Priisid, Still, Trans. Ent. Soc. Lond. ser. 3, vol. i. p. 57-1 (1803). As all the specimens of this genus in my own collection are of the female sex, and bials description was founded on female specimens in the British Museum, I have thought it hest to give the original generic diagnosis.
"Caput parvuin, thoracis antico hand latins, vertice aiif^usto; fronte compressa, Talde prominentc, basin versus angustata. Antennarum articulus primus elongatus. Thorax postice quam antice latior, margine antico utiinKiuo Icviter elevate, subrecto, limbo postico angusto, angulis basalibus retrorsum leviter produetis.

"Cystosomati*affinegenus."
To the above description may be added the male characteristic of having the abdomen considerably dilated.
Prasia is a genus, according to present knowledge, quite confined to the Malayan Archipelago. Its species are rare in collections, and those of the male sex are particularly scarce.

2 . Head trianrjular, the froat protniueutlj' and subacutely produced ; the vertex with the lateral margins slightly convex beliiud the eyes and prominently produced in front of the eyes. Pronotum at posterior angles about twice as broad as anterior margin; the posterior angles ampliated, deflexed to base of tegmina, and broadly rounded at apices. Abdomen above distinctly and longitudinally raised and carinate. Face very prominent, strongly compressed and wedge-shaped, concavely narrowing on its apical half. Eostrum reaching the intermediate coxiB. Tegmina elongate ; the costa very slightly depressed immediately beyond base, and then slightly raised and convex from about the apex of upper ulnar area ; the interior ulnar area with the apes slightly but distinctly broader than base ; the space between the apices of the postcostal vein and the postcostal ulnar ramus ampliated, and the costal margin very finely hirsute ; apical areas eight, the eighth broadest and shortest ; an additional curved and rudimentary vein conuectmg the base of the second and the apex of the fifth ulnar areas ; this vein is distmct and perfect for a short distance from the base of the second and into the third ulnar areas, after which it is subobsolete ; basal area almost twice as long as broad.
^ . Abdomen inflated ; tegmina shorter than in female ; tympana totally uncovered ; opercula rudimentary.
Since I founded this genus on a Cclebesian species, two other species have been described by Dr. Karsch, one from Port Moresby in New Guinea, and the other from Thursday Island in Torres Straits. These habitats at present constitute our knowledge of the geogi-aphical distribution of Lembeja, and two of the three species are included in our restricted fauna. 1. Lembeja maculosa. (Tab. VII., ligs. 13, a, //.)

2 . Pale ochraceous or greenish ; ocelli castaneous ; mesonotum with two central obconical dark spots, the bases of which rest on anterior margin ; on each side of these is a much longer and more acutely pointed spot, and a small round spot in front of each anterior branch of the cruciform basal elevation, which is marked by two central darker lines ; abdomen above sparingly pilose, the apical segmental margins paler. Body beneatli and legs pale ochraceous or greenish ; femora near apices, tibiro ne-ir bases and at apices, and apices of tarsi, fuscous. Rostrum with the apex pitchy. Tegmina and wings pale hyaline, the first minutely spotted along all the veins anil more or less across its apical half.

Head including eyes narrower than the base of the mesonotum ; ocelli about as wide apart from eyes as from each other ; eyes large, oblique, and l^rominent ; front broad and obtusely convex. Pronotum with the lateral margins non-ampliated, the posterior lateral angles ampliated and rounded. Metanotum distinctly produced and visible. Tympanal coverings absent, the tympana entirely exposed and uncovered. Anterier femora robust and strongly spined. Opercula short, somewhat rudimentary, not covering the sonorous cavities. Tegmina and wings hyaline ; tegmina with eight apical areas, the seventh area longer than the eighth ; interior ulnar area with the base and apex about equally broad, its anterior margin slightlj' convex ; basal cell considerably longerthanbroad.
The Malayan Archipelago is clearly the head-quarters of this genus, which is also probably largely represented throughout the Pacific region.
