10 Mr. F. P. Pascoe on some new or little-hnown 



portance to allow of its being referred to that group. Bitoma prolata 

 {ante, vol. i. p. 102) belongs to Phormesa*. 



PJiorraesa lunaris. (PI. III. fig. 6.) 



P. fusca ; prothorace lateribus rotimdatis, utriuque bicostato, costis vix 

 elevatis, interiore postice duplicata, exteriore interrupta ; elytris luteo 

 bifasciatis. 



Hah. New Guinea (Dorey). 



Moderately broad, dark brown ; head finely and thickly granulose, 

 considerably dilated before the eyes, and hiding the basal joint of the 

 antennae ; mentmn quadrate ; labium transverse, slightly emarginate ; 

 maxillary lobes narrow ; prothorax rough, granulated, rather contracted 

 at the base, tbe disk with two slightly elevated costae on each side, the 

 interior approximating anteriorly, and forming a short, closed canal 

 towards the head, posteriorly also approximating, then doubling back, 

 and forming a short loop at the base, the exterior costa interrupted in 

 the middle ; el}i;ra ovate, wider than the prothorax at its junction, with 

 five crenulated costae on each, the intervals with a double row of large, 

 deeply impressed punctm^es, a yellow semilunar band near the middle, 

 and a narrower and straighter one below it; legs pale ferruginous; 

 body beneath dark brown. Length 1^ line. 



On comparison with Phormesa pi^olata it will be seen that, besides 

 the markings on the elytra, the differences will be found chiefly in 

 the prothorax, which in that species is not contracted, except close 

 to the base, and is then a little before the base as broad as the 

 elytra, that the costge are much more strongly marked, and the 

 outer one especially is entire in its whole length. Phormesa prolaia 

 is also larger, and proportionally not so broad. 



Phormesa inornata. 



P. fusca ; prothorace lateribus medio subparallelis, basi rotundatis, utrinque 

 bicostato, interiore postice duplicata, exteriore vix elevata ; elytris pos- 

 tice obsolete lateo signatis. 



Ifab. New Guinea (Dorey). 



A longer species than the last; the sides of the prothorax less 

 regularly rounded, and broader in proportion to its length, the ex- 

 ternal costa straighter and nearly entire ; the elytra altogether brown, 

 except a very faint spot on each near the base. 



* The diagnosis for this will now read thus : — ■ 

 Phormesa prolafa. 

 P. fusca ; prothorace utrinque bicostato, costis fortiter elevatis, interiore postice 



duplicata ; elytris obsolete luteo-maculatis. 

 Hab. Batchian.
