(14) Die slot a kauaiensis, sp. no\'. 



Nigricans, antennarum basi palpisque fusco-testaceis, pedibus testaceis ; capite 

 fortiter punctate, thorace elytrisque subtilissime sculpturatis, peropacis. Long. 2\ mm. 



This differs from D. sitbplagiata as follows : the head and the thorax are a little 

 narrower, the punctures of the head are not quite so large, and there is a very small 

 obscure depression on the middle of the head ; the sculpture ot the thorax and elytra is 

 very obsolete; the antennae are a little stouter, though the insect is smaller. One female 

 specimen. 



Hab. Kauai, Koholuamano, 4000 ft. 15. iv. 1895 (Perkins).

Diestota piincticeps Sharp, Tr. ent. Soc. London, 1880, p. 41. 



Ls unusually coarsely sculptured all over, but is not in any way to be compared 

 with D. scitlpt2trata, and the sculpture and form are very different from D. carinata. 



Hab. Oahu, Honolulu (Blackburn).

I am indebted for the identification of this species — the type of the genus Diestota — 

 to Mons. A. Fauvel, who examined Mr Blackburn's type. The species seems to be 

 very rare; Mr Blackburn found only one specimen; as Dr Perkins met with another 

 example in the same locality after an interval of about 30 years, it would appear to be 

 really an inhabitant of Hawaii. 



D. testacea is not at all like any other Hawaiian species; it may be distinguished by 

 its short robust form, rulescent colour, thick antennae, and a more numerous punctuation 

 of the abdomen. As it is the type of the genus we give a figure of our unique — and 

 unfortunately mutilated — example. 



Hab. Oahu. "Unique, on the shore near Honolulu" (Blackburn); Honolulu, 

 coast, XI. 1900 (Perkins) — S. France and Ceylon.
