44 Longicornia BJalayana. 



" ventricose," that is, a joint gradually swelling out to ihe middle, 

 but only on one side. As usual, there are gradations even in the 

 same antenna, and the form also appears to pass into the obconicil 

 joint we see in Ebceides. The type of this genus bears a strong 

 general resemblance to Callia, the members of which group are 

 also found to imitate various species of the Galleruc'idoi. The 

 thoracic spine is well marked, and directed obliquely backwards ; 

 the prothorax behind it curving inwards to the base. The pro- 

 tibiae are slightly curved, a character which finds its greatest deve- 

 lopment in Ebceldes. The anterior acetabula are strongly angulated 

 in this genus, especially in C. tr'inlis.

C. nigra, nitida ; capite prothoraceque croceis ; elytris violaceis. 



Hah. — Aru. 



Dark violet, shining, covered with a very fine and thin pubes- 

 cence ; head saffron-yellow, narrower than the prothorax ; eyes

 small, triangular ; elytra irregularly and rather strongly punctured 

 at the base and along the suture, the punctures linearly arranged 

 at the sides; body beneath chesnut-brown, shining, the breast 

 yellowish ; legs dark brown, the coxse and last two joints of the

Camptomyne bicolor. (PI. III. fig. 10.) 



C. nigra, vix nitida ; capite prothoraceque luteo-croceis. 



Hab. — Batchian. 



Closely allied to the last, but the yellow of the head and pro- 

 thorax is darker and duller ; the elytra are quite black, only slightly 

 shining, the punctures more crowded and more impressed, so as 

 to leave more the appearance of lines between them, and the pro- 

 thorax is proportionally smaller when contrasted with the head. 



Length 2 lines. 



Camptomyne tr'istis. 



C. nigrescens ; prothorace fusco-lutescente. 



Hab. — Batchian. 



Very slightly pubescent, reddish, or rather perhaps purplish- 

 black ; head blackish, obsoletely punctured, as broad as the pro- 

 thorax ; eyes black ; prothorax very minutely punctured, dark 

 luteous; scutellum roundish ; elytra purplish-black, with the 

 punctures less crowded than in the last two species, althougli quite
