S2 MR. M. JACOBY ON THE [Feb. 1, 



Easily distinguished by tlie densely rugose-punctate thorax and 

 the cupreous margin of the latter and of the elytra. 



Dermorrhytis lewisi, sp. nov. 



Greenish or brownish cupreous ; basal joints of the antennae and 

 the legs obscure fulvous ; head and thorax closely and strongly 

 punctured ; elytra strongly punctate-striate, the interstices trans- 

 versly strigose throughout. 



Length 2|-3 lines. 



Head closely rugose-punctate, the epistome not separated from 

 the face ; labrum fulvous. Antennae very slightly thickened at 

 the apical joints, the third and fourth joints equal, the five or six 

 lower joints fulvous, the others fuscous. Thorax transverse, the 

 sides nearlj' straight, the surface closely and strongly punctured, 

 the interstices everywhere transversly rugose. Elytra subcylindrical, 

 slightly narrowed behind, punctured like the thorax, but the inter- 

 stices transversly raised and extending across the entire surface ; 

 underside covered with fine silky-white pubescence. 



Dikoya. 



The straight sides of the thorax, in connection with the trans- 

 versely rugose interspaces of the same part, and those of the entire 

 disk of the elytia, will help to distinguish this species principally 

 from B. piceipes, Brdy. 



Dermorrhytis ornatissima, Baly. (Plate X. fig. 6.) 



Dermorrhytis fasciato-rutilans, Leto vre. 



Balangoda. 



This species, of which the two above names are synonymous, seems 

 to vary greatly in regard to size and coloration ; all the specimens 

 contained in my collection are devoid of any cupreous spots on the 

 thorax. In the present collection the specimens obtained by Mr. 

 Lewis are much smaller, and have a broad transverse reddish-cupreous 

 band occupying nearly the entire disk of the thorax. 



Dermorrhytis variabilis, sp. nov. 



Greenish aeneous below ; above metallic green, the shoulders, 

 sides, and apices of the elytra reddish cupreous ; head and thorax 

 remotely punctured, the interstices flat ; elytra punctate-striate, 

 the sides transversely strigose ; basal joints of the antennae and the 

 legs fulvous. 



Var, Above brownish cupreous. 



Length 2-2| lines. 



Head rather flattened, finely and moderately closely punctured, 

 the interstices slightly rugose anteriorly only ; the epistome not 

 separated from the face, its anterior margin nearly straight ; labrum 

 fulvous. Antennte longer than half the length of the body, the five 

 terminal joints slightly dilated, black, the others fulvous. Thorax 

 nearly twice as broad as long, the sides straight and slightly subangulate 

 or dentate; surface remotely and distinctly punctured, the interstices 

 not raised. Elytra punctate-striate at the inner disk, irregularly
