132 Mr. F. P. Pascoe on the Colydiide 
slightly elevated granules, which is interrupted in the middle, the inner 
costa forming posteriorly a triangular loop, the interval between the two 
loops forming alozenge-shaped space ; scutellum punctiform ; elytra as 
broad as the prothorax, with crenate coste, the intervals so impressed as 
to form three lines of oblong elevations; body beneath rufous brown, 
finely punctured ; antenne and legs ferruginous. Length 13 line. 
The triangular form of the posterior loops, which are confluent at 
one of their angles, thus forming a lozenge-shaped space at the 
base, will readily distinguish this species. 
Phormesa elevata. ; 
P. fusca; prothorace costa exteriore obsoleta, interiore postice breviter 
incurva. 
Hab, Macassay. 
Rather broad and convex, especially posteriorly, dark brown; head 
broad, dilated below the eyes, granulate; prothorax granulate, rounded 
at the sides with an obscurely rugose margin, no external costa, internal 
costa simply incurved posteriorly, not forming a loop; scutellum punc- 
tiform ; elytra rather broader than the prothorax, strongly costate, the 
inner and second costée depressed near the base, the intervals with ob- 
scure transverse impressions, three or four ill-defined luteous bands on 
the disk; body beneath dark ferruginous; legs and antenne ferruginous. 
Length 13 line. 
A very distinct species. The absence of the external costa, 
together with the internal costa not forming a loop, will distinguish 
it from all Phormese hitherto described, as well as some others in 
my collection, in which the last-mentioned character is also present. 
GEMPYLODES. 
Cuput exsertum, oblongum. Antenne basi tectee, 11-articulate, haud 
clavate, articulo basali brevi, vix incrassato, tertio longiore, ceeteris 
gradatim crassioribus. Oculi prominuli, integri. Prothorax elon- 
gatus, basi constrictus, medio canaliculatus vel suleatus. Elytra cylin- 
drica, carinata, apice declivia. Tibie trigonate, calcarate.  Tarst 
elongati. Corpus angustum, elongatum. 
Erichson has described in very few words a genus from Madagascar 
named Mecedanum, evidently allied to this, but which, I think, will 
be found to differ in the character of its prothorax ; and, according 
to the deseription, in the antenne fringed with fine hairs, and in the 
greater length of the basal joint of the tarsi. Colydiwm is also 
another genus to which this is allied. I have another species, 
from Siam, for which I am indebted to the kindness of W. Wilson 
Saunders, Esq., which is one of the finest of the Colydians.
