COLEOPTERA 397 



Group 4, 



(28) Droiiiaco/its ccplialotcs, sp. nov. 



Parum elongatus, convexus, piceo-niger, antennis pedibusque rufis, dense subtiliter 

 punctatus, flavo-pubescens, parum nitidus : capite fortiter profundequc punctate. Long. 



5l mm- 



In size and form this comes nearest to D. concolor, but differs irom it and from 



all the other species, except D. pnncticcps, by the punctuation of the head differing in a 

 very remarkable manner from that ot the rest of the liody. From P. puticticcps it differs 

 in not being shining, owing to its denser and finer punctuation and pubescence. The 

 antennae are rather long, and bear a conspicuous setosity, the fourth joint is longer 

 than broad, and as long as the fifth : the terminal joint is longer than usual but not 

 twice as long as the tenth. In the unique specimen it is peculiarly flattened or com- 

 pressed. It is possible this insect may be the other sex of P. pitncticcps, liut I think 

 this is highly improbable. In fact I shall not be surprised if P. ccphalotcs [jrove to be 

 a winged, and P. puncticcps a wingless, form. 



Hab. Kauai : high plateau, August, 1S96 (no. 6S2, Perkins). 



(29) Proiuacolus puucfiaps, sp. nov. 



Parum elongatus, anterius et posterius angustatus, piceus, nitidus, flavo-pubescens, 

 antennis ruio-piceis, pedibus rufis ; thorace magno, anterius fortiter angustato ; capite 

 fortiter punctato, nitido. Long. 4^ — 5 mm., lat. i| mm. 



This insect has the thorax large in proportion to the elytra, and the hind angles 

 large. The antennae are rather long and pilose, the space by which they are .separated 

 is less than usual. There is not much punctuation on the thorax, so that the deep 

 coarse punctures on the head are strongly contrasted with the other sculpture. 



Four specimens. I think the two sexes are among them, but am not at all sure. 

 The species will I think prove to be apterous, its proportions being more like those of 

 P. pachydcres than those of the forms I have assumed to be winged. 



Hab. Kauai : on the high plateau, August, 1896 (no. 682, Perkins). 



(30) Proniaeohis haivaiicnsis, sp. nov. 



Piceo-niger, subtiliter flavo-pubescens, nitidus, antennis piceis, pedibus fusco- 

 testaceis ; thorace obsolete punctato. Long. 4I mm. 



This is closely allied to P. puncticcps, but lacks the salient features of that species ; 

 it is distinguishable from it by the less coarsely punctured upper surface, and by the 

 thorax being less broad behind and less narrowed in front. The antennal cavities are 

 not at all margined above. One specimen.
