COLEOPTERA 555 



Oi.iGOTA, Deroligota subo-. nov. 



Metasternuin short; middle coxae only moderately distant, breast between them 

 without transverse suture. Elytra not longer than the pronotum. Form slender. 

 This is probably an apterous torm.

This is distinguished from all the other Oligotinae by the very short elytra. 



The short series before me comes from three or four islands and exhibits a good 

 deal of variation, so that I think there may prove to be more than one species oi 

 Deroligota. 



The island my original type came from is somewhat uncertain. Mr Blackburn 

 mentioned Maui and Hawaii as the homes of the species. When he sent me the 

 specimen I described he did not tell me which island it came from. It does not agree 

 with the other individuals before me, except with one specimen from the island of Lanai. 

 These two individuals are darker in colour and have the elytra rather longer than the 

 examples from Oahu and Kauai. 



Without a larger series of specimens I cannot decide as to the treatment of these 

 lorms as more than one species. The species appears to be rare ; usually only one 

 specimen has been found at a time.

 (2) Oligota [Holobus) clavicoruis, Sharp. 



Oligota clavicoruis Sharp, Tr. ent. Soc. London, 1880. p. 44. 



Distinguished abruptly from all the other species, by the short convex form and by 

 the abdomen narrowed from base to apex and by the terminal half of the abdomen being 

 bright yellow. 



In addition to my original type I have seen but one other example; and even this 

 I think will ultimately prove to be another species, as the club of the antenna is not so 

 broad, and the 6th joint not transverse. 



Mr Blackburn's example was found in straw imported from England, and that had 

 lain for two years in Honolulu. Dr Perkins' example was iound twent\- years sub- 

 sequently, in July 1900. So that it would appear that this subgenus is now constantly
