156 REV. H. S. GORHAM ON NEW COLEOPTERA. [ Mar. 16, 
spines. The apex of the prosternum is not so widely rounded but sub- 
mucronate. The apex of the jaws is notched, much as in EZncymon 
and Hngonius, the teeth being of equal length and the exterior one 
not bifid. The front tibiz of the males have a very small tooth 
near their apex. Engonius, to which this genus approaches in some 
of its characters, has the apex of the elytra obliquely truncate, so 
that they are open at the sutural angle; in the present genus the 
elytra are together uniformly rounded. 
1. SticTOMELA CHRYSOMELOIDES. (Plate XVII. fig. 6.) 
Oblonga, elytris apice equaliter rotundatis, nigro-enea, nitida ; 
capite prothoraceque inequalibus, crebre sat fortiter punctatis, 
hoc profunde canaliculato ; elytris crebrius subtiliter punctatis, 
perobsolete subsulcatis, callo humerali modice elevato, obtuse 
carinato, punctisque quatuor aurantiacis, duobus basalibus, duobus 
subapicalibus, oblique positis. Long. 9 millim. 3 9. 
Mas. Tibiis anticis ad apicem intus excisis, intermediis leviter cur- 
_  vatis, apice mucronatis. 
Hab. Dickoya, Ceylon. 
Head brassy black, a little shining ; epistoma thickly and strongly 
punctured, posterior part less thickly ; antennee as in Spathomeles, 
but the club rather lax, apical joint obliquely compressed at the tips. 
Thorax with the surface shining but uneven, the principal impression 
being a central channel with a punctiform pit on each side in the 
middle, a basal transverse line, and the ordinary basal sulci; the 
sides are, however, wrinkled; the lateral margins are much rounded 
in front, and the front margin rather deeply excavated and bisinuate, 
the front angles being acute. The humeral callus is raised into a 
blunt carina, terminating in the external one of two basal, orange, round 
spots; the two apical ones are placed somewhat obliquely, that 
nearest the suture being furthest from the apex, and oblong but 
irregular in shape. The femora are clavate and distinctly punctured ; 
the tibiz are bent a little in both sexes, but more strongly so in the 
male, and in that sex terminate inwardly in a short mucro; they are 
pubescent at the tips. The tarsi and claws are pitchy, clothed with 
golden pile beneath. The intercoxal plate of the basal ventral seg- 
ment is sparsely but deeply punctate. 
Four specimens, three males and one female, of this beautiful 
species were captured by Mr. Lewis. 
2. STICTOMELA OPULENTA. 
Oblonga, nitida, nigra ; elytris confertim crebrius punctatis, singulis 
maculis sex rubris, tribus basalibus, tribus subapicalibus irregu- 
laribus, quasi fasciam formantibus. Long. 10 millim. 6. 
Mas. Tibiis anticis dente parvo adjacente, juxta apicem infra dentem 
excisis ; segmento apicali ventrali, tuberculo instructo. 
Hab. Ceylon. 
Head strongly and deeply punctured, the epistoma especially so, 
with fewer and more scattered punctures; antennee as in Engonius, 
but with the club a little more lax. Thorax uneven but shining,
