COLEOPTERA 575 



bad preservation but seems to indicate that this species is rather variable, or else that I 

 have placed more than one under the name.

 Oahu : mountains, in decaying wood (Blackburn); Waianae mts. iv. 1892 (Perkins, one

Dicstota plana Sharp, Tr. ent. Soc. London, 1880, p. 38. 



This species is certainly very close to D. parva, and I should like to see more 

 specimens before I can say that I quite understand these minute Diestotas.

(28) Dicstota clavicornis, sp. nov. 



Minus lata et depressa, nigricans, antennis fuscis, basi palpis pedibusque fusco- 

 testaceis; capite subtiliter obsolete punctato, anterius minus opaco, medio subtiliter 

 longitudinaliter foveolato ; prothorace minus transverse, cumque elytris subtilissime 

 sculpturatis et pubescentibus; antennis validis aj^icem versus fortiter incrassatis. 

 Long. 2^ mm. 



This is a distinct little species, the comparatively narrow head, and the very thick 

 antennae, separate it from all the others. D. molokaiensis, with a narrow head, is coarsely 

 sculptured. We have only one specimen, its sex is uncertain. The mesosternum is 

 carinate, and the metasternal process between the middle coxae is narrower than usual. 

 This last character distinguishes D. clavicornis strongly from D. testacca, which though 

 it has somewhat similar antennae differs greatly in nearly all other characters. 



Hab. Maui, Haleakala, 5000 ft. April 1894 (no. 125, Perkins). 



(29) Dicstota trogophlcoidcs, sp. nov. 



Minus lata et depressa, nigra, antennis fuscis, palpis pedibusque fusco-testaceis; 

 obsoletissime sculpturata et pubescens; prothorace vix transverse, antennis mediocribus 

 apicem versus fortiter incrassatis. Long, vix 2 mm. 



This minute form will not be mistaken for any other, in consequence of the narrower 

 and more elongate head and thorax, though D. clavicornis to a considerable extent 

 connects it with the rest of the genus. We have only one specimen and I do not think 

 it desirable to take it off the card to examine the under surface. 



Hab. Molokai, 21. ix. 1893 (Perkins).
