394 FAUNA HAWAII EN SIS 



(19) Droinacolus elateroidcs, sp. no\. 



Robustus, sat latus, anterius satis, posterius magis acuminatus, nigricans, elytris 

 postice rutesctntibus, parum nitidus, crebre punctatus et tlavo-pubescens, antennis 

 pedibusque piceis vcl rufis. Long. 5f — 7^- mm. 



Smaller than D. obtiisns, more acuminate, with rather closer and finer punctuation 

 and somewhat longer antennae. 



Mr Perkins found six specimens that I assign to this species and portions ot two 

 others ; they are most of them much mutilated, and as they exhibit a good deal of 

 difference I am not sure that all are one species. Two or three of them have the 

 antennae thicker than in any of the other Hawaiian species. As a similar difference 

 occurs in the specimens which I have determined as D. obfiisns, it is possible that this 

 is a sexual character. They were found on various occasions, and therefore, on the 

 other hand, they may not be all one species. 



Hab. Maui. Haleakala, 3000 — 4000 ft. in April and May, 1894 and 1896 (Perkins). 



(20) Dromaeohis sp. 



Mr Perkins found thorax and head, without appendages, of a Dromaeolus, prob- 

 ably near D. elatcroidcs and of about the size of that species, but with the thora.x 

 evenly and strongly narrowed from the hind angles to the front. 



Hab. Hawaii. Olaa, Sept. 1896 (no. 688, Perkins). 



(21) Dromaeohis sp. 



Mr Perkins found portions of a specimen on Molokai that resembles an extremely 

 small D. elateroides but has the wings reduced to mere rudiments. Although I am 

 not sure that D. elateroides is a winged form yet I have little doubt of it, and I consider 

 therefore that the Molokai fragment represents a distinct species. 



Hab. Molokai : mountains, in June, 1896 (no. 593, Perkins). 



(22) Dromaeolus brachycemis, sp. nov. 



Nigro-fuscus, subparallelus, flavo-pubescens, haud nitidus, dense punctatus, antennis 

 pedibusque ruhs ; antennis articulis quarto et quinto subaequalibus, singulo quadrate. 

 Long. 7-i- mm. 



We have only one example of this species, and it is mutilated, having been found 

 dead (as is often the case with Eucnemidae), but it is so distinct that I venture to 

 describe it.
