albo-margiuato : infra subnitida, marginibus segmentorum abdo- 

 minis albis. 



Deep glossy black ; line below the eye, another behind, and 

 one on the vertex, posterior border of the prothorax, scutellum, 

 and several transverse spots on the elytra, pure white (formed 

 by dense patches of short hairs) ; body beneath and legs black, 

 less glossy than on the upper surface, sparingly covered with a 

 delicate ashy pubescence ; margins of the abdominal segments 

 white. Length 10 lines. 



This handsome insect is nearly allied to the Philippine Agnia 

 clara. Agnia differs from Cereopsius, principally, in its unarmed 

 prothorax. 



Trihammatus. 



Chevrolat, Rev. et Mag. de Zool. No. 2. 1857. 



Trihammatus tristis. 



T. niger, nitidus, subtiliter griseo-pubescens ; prothoracis marglne 

 antico et vitta suboculari, lateribusque pectoris infra albis ; elvtris 

 maculis quatuor atris. 



Glossy black, covered with a short, dense, greyish pubescence, 

 giving the upper surface a dull leaden hue; head sulcated in 

 front, an oblique yellowish white band beneath the eye, which 

 is continued along the sides of the thorax beneath ; prothorax 

 strongly spined on the side, the anterior margin narrowly bor- 

 dered with yellowish white ; scutellum triangular, truncated 

 posteriorly ; elytra thickly and irregularly punctured, with se- 

 veral small shining tubercles at the base, and two opake deep- 

 black irregular spots on each (one before, the other behind the 

 middle) ; antennje (c?) t\Wce as long as the body. Length 12 

 lines. 



The females of this genus (which have not been hitherto 

 described) differ essentially from the males in the fourth joint 

 of the antennae, only, being enlarged; and this enlargement 

 assumes a cylindrical form, not rounded or pear-shaped, as in 

 the other sex. 



Cylindropomus. 



Blanchard, Voyage au Pole Sud, iv. p. 268. 



Cylindropomus grammicus. 



C. niger ; prothorace utrinque vittis duabus albis ; elytris fuscescen- 

 tibus, lineis duabus longitudinalibus, antice posticeque conjunctis, 

 albis. 



Dull black ; head broader than the prothorax, impunctate, 

 minutely pubescent, a raised line on the vertex and an oblong
