Longicornia Malay ana. Ill 



cence is longer, denser, and uniform in its colour, and the character 

 of the insect is altogether different ; the brown portion of the 

 pattern, however, remains nearly the same, except that the bands 

 are a little more angular ; the legs are somewhat longer and 

 stouter; the antennae are not tufted, at least in my solitary speci- 

 men, and the fourth and fifth joints are white at the base.

Cacia plagiala. 



C. fusco-castanea ; capite prothoraceque tenuiter griseo-pubes-. 

 centibus, hoc fusco-quadriplagiato ; elytris castaneis, singulis 

 tribus plagis griseo-pubescentibus. 



Hab. — Saylee, Aru. 



This is also a suspicious species, having precisely the same 

 style of coloration on the prothorax as the last two, with the addi- 

 tion of a patch on each side, but this is also the case with some 

 individuals of C. intricata. In C. plagiala the prothorax is very 

 much broader than in C. scenica, (but even this character is vari- 

 able in C. instablUs). As to the elytra, we have only to connect 

 the three bands of C. intricata by a stripe along the suture and 

 carry the stripe down to the apex, and we have pretty nearly 

 C plagiata. The two specimens before me show some differences, 

 and probably belong to a variable species, but the evidence is not 

 sufficient at present to justify its union with the last.

Cacia picticornis. 

 Pascoe, Trans. Ent. Soc. ser. 2, iv. 249. 



C. fusca, subtilissime griseo-pubescens ; elytris flavo-guttatis ; 

 antennis pedibusque nigris, albo-annulatis. 



Hab. — Sarawak. 



Dark brown, covered with a very fine and thin greyish or 

 reddish-grey pubescence ; head with a large triangular whitish 

 patch below the eye, and a broad line between the eyes ; protho- 

 rax with an indistinct yellowish stripe on each side, or this is broken 

 up into spots ; soutellum with a triangular impressed spot on the 

 apex ; elytra convex, regular at the base, with several yellowish 

 round spots ; body beneath black, with a pale ashy pubescence, 

 and a yellowish tint at the sides ; legs black, annulated with white ; 

 tarsi black, with the two basal joints white; antennse half as lontr 

 again as the body in the males, the third and fourth joints at the 

 base, and nearly the whole of the fifth, white, apex of the fourth 

 joint tufted.
