398 FAUNA HAWAIIENSIS 



(31) Droniaeoliis pachydercs, sp. nov. 



Brevis, i:)Osterius angustatus, piceus, flavo-pubescens, antennis rufo-piceis, pedibus 

 rufis ; prothorace subobsolete punctate. Long, 3^- — 4^: mm. 



This little insect is smaller than D. puncticcps or D. Iiaivaiiensis, and has the 

 thorax less narrowed in front than the first of these. The antennae are rather long, 

 formed much as in D. puncticeps. but rather less long and stout, the fourth joint, as in 

 that species, as long as the fifth : the elytra are finely striate, the sutural stria rather 

 deep, and distinctly deeper at the ape.x, but not so as to gi\'e rise there to the appearance 

 of foveation that exists in many of the species. The fourth and fifth joints of the 

 tarsi are small, the fifth being much smaller than it is in D. puncticeps. The wings 

 in this species are reduced to small functionless slips a little longer than the metathorax, 

 remarkably narrow, without nervures. 



Three examples of this species were bred by Mr Perkins in August, 1900, from 

 Pipiuriis \ Tantalus (no. 785). I also assign to this species four individuals bred by 

 Mr Perkins from Koa wood, in August, 1900 (no. 892). The locality though not 

 stated is doubtless the mountains near Honolulu. 



H.\B. Oahu (Perkins, as above noted). 



Dromacohis pachydcrcs, var. kauaicnsis, var. now 



Brevis, posterius angustatus, ferrugineus, flavo-pubescens, antennis extrorsum ob- 

 scuris, basi ciilutiore, pedibus fiavis ; prothorace subtilius punctato. Long. 4 mm. 



Hab. Kauai : mts. Waimea (nos. 267, 862, Perkins). The two specimens are 

 so near to the specimens from Oahu that I do not venture to separate them on such 

 slight evidence. There is however a little difference in the form of the angles of the 

 thorax, which are straighter than in the Oahu examples, and not in the least incurved 

 (no. 267). 



A third specimen is considerably smaller, narrower, and less punctate. I have 

 little doubt it is a different species, but the individual is too mutilated to treat as a 

 type of a named species in so difficult a group. 



(32) Drouiaco/iis graiidicollis, sp. now 



Brevis, posterius acuminatus, thorace magno, ferrugineus vel fusco-ferrugineus, 

 crebre subtiliter punctatus, flavo-pubescens ; elytris striatis. Long. \\ — 5 mm. 



Very close to D. pacliydcres ; slightly longer and narrower behind, with elytra 

 a litde more distinctly striate, the antennae a little thicker, and the terminal joint of 

 the tarsi distinctly longer ; the fourth joint of the antenna is short, not longer than broad. 



In addition to the three examples from Hawaii from which I describe this species, 

 Mr Perkins found a single individual in each of three other islands ; they are so near to
