This species also bears a superficial resemblance to Synia 
melanaria, but has the clypeus of a Celophora. It is not unlike 
C. Jansoni, Crotch, but is smaller, with the prothorax and under- 
side marked with black, and the tips of the elytra only very 
narrowly reddened ; its puncturation, moreover, is considerably 
less strong. It is also near C. vidua, Muls., from Java, but is a 
little smaller, with the median line of the prothorax red, the 
elytra tipped with red, the abdomen (except at the sides) black,

C. guttata, spec nov. Subcircularis ; sat convexa; sat crebre 
minus subtiliter punctulata; nigra, prothorace (parte mediana

anterioribus 4 rufo-testaceis, elytris maculis binis magnis 
sanguineis (altera antemediana transversa, altera subapicali

A very distinct species. Ido not think any very near it has 
been described.

C. flavidus, sp. nov. Hemispheericus; minus sabtiliter sat crebre 
punctulatus, puncturis magnis seriebus binis in elytris latera 
versus irregulariter positis; callo humerali valde prominenti; 
flavus, elytris macula communi elongato-triangulari in sutura 
alteraque transversa postmediana nigris, his maculis in 
sutura confluentibus. Long., 23.1; lat., 2 1. 
The puncturation is very similar to that of C. renipustulatus, 
Scriba. The sides of the prothorax are not pubescent. The 
black markings on the elytra consist of an elongate triangle, with 
its base occupying about the middle quarter of the base of the 
elytra, and its apex on the suture considerably behind the middle, 
and a post median fascia touching the margin on both sides, and 
of very irregular shape, with its hindmargin produced on the 
suture nearly to the apex. The two black marks meet on the 
suture. The spine on the tibie is very strongly developed.

This genus might easily be subdivided on structural characters 
of considerable importance. The species differ in the form of 
the clypeus to an extent that seems inconsistent with the im- 
portance attributed to that character in founding the sub-family 
Chilocorites upon it. In O. bilunulatws, Boisd., the clypeus is
