lOti VESTA SIMATI{KNSI«. 



One .specimen (inaleV) taken at, Leboug (Sum. Exp.), 

 These species seem to me , while pertaining to the true 

 subfamily Lyndae, to form a passage to the Calochro- 

 midae, and perhaps ,Homalisidae. The abdominal segments 

 are however normal in the two males here described.

16. Vesta sumatrensis , sp. n. 



Nigro-picea , sub-nitida ; prothorace , coxis anticis et in- 

 termediis , abdominisque segmentis duobus ultimis ventra- 

 libus rufis; thorace brevi, disco obsolete canaliculato , an- 

 tice et ad latera fortiter subrugose punctato. — Long. 10 

 millim. cT (?). 



Antennae as long as would reach to the middle of the 

 abdomen, joint 2 short but easily seen, three much larger 

 triangular , four to ten compressed widely serrate , apical 

 as long as preceeding one, simple. 



The thorax is transversely semicircular, narrowed in front, 

 so that the hind angles are acute and a little produceil 

 backwards , the central part is raised and smooth , and 

 with a short channel, distinct in the middle, but not con- 

 tinued on the punctured part in front. The elytra have 

 three distinct raised nervures, and a fourth less distinct 

 sub-costal one. The legs are black excepting the bases of 

 the two anterior pairs.

 Alahan pandjang (Sum. Exp.) , and a specimen of a va- 

 riety from Solok (Schagen van Leeuwen). 



The smaller species of Vesta are so singularly like spe- 

 cies of the American genus Lucidota that the only charac- 

 ters by which I can distinguish them are that the second 

 joint of the antennae is quite distinct and obconic , whe- 

 reas in fjucidota the same joint is venj small and trans- 

 verse and closely articulated with the third joint. Again 

 in Vesta the first tarsal joint is always as long as the two
