ao Mr. F. P. Pascoe on some new or little-known 
portance to allow of its being referred to that group. Bitoma prolata 
(ante, vol. i. p. 102) belongs to Phormesa*. 
Phormesa lunaris. (Pl. III. fig. 6.) 
P. fusca; prothorace lateribus rotundatis, utrinque bicostato, costis vix 
elevatis, interiore postice duplicata, exteriore interrupta ; elytris luteo 
bifasciatis. 
Hab. New Guinea (Dorey). 
Moderately broad, dark brown; head finely and thickly granulose, 
considerably dilated before the eyes, and hiding the basal joint of the 
antenne ; mentum quadrate ; labium transverse, slightly emarginate ; 
maxillary lobes narrow ; prothorax rough, granulated, rather contracted 
at the base, the disk with two slightly elevated coste 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 ; elytra ovate, wider than the prothorax at its junction, with 
five crenulated costz on each, the intervals with a double row of large, 
deeply impressed punctures, a yellow semilunar band near the middle, 
and a narrower and straighter one below it; legs pale ferruginous; 
body beneath dark brown. Length 13 line. 
On comparison with Phormesa prolata 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 costz are much more strongly marked, and the 
outer one especially is entire in its whole length. Phormesa prolata 
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 luteo signatis. 
Hab. 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 prolata. 
P. fusca; prothorace utrinque bicostato, costis fortiter elevatis, interiore postice 
duplicata ; elytris obsolete luteo-maculatis. 
Hab. Batchian.
