I40 FAUNA HAWAIIENSIS 



are covered with a cinereous bloom. The apical portion of the rostrum in the ? (from 

 the insertion of the antennae to the apex) is impunctate, or at the most has a few 

 excessively feeble and fine punctures. 



(2) Diyophthortis distinguendus, sp. nov. 



Niger, piceus, vel rufescens, haud robustus, grosse punctatus. Rostri (?-is pars 

 anterior opaca, rugoso-punctata, $-ae nitida, subtilius sat distincte fere ad apicem 

 punctata. Oculi sat magni. Pronotum densissime punctatum, antice fortiter constrictum. 

 Elytra satis profunde sulcata, sulcis confertim grosse punctatis, interstitiis haud cinereo- 

 sericeis, subtilissime punctulatis, et brevissime pallide setulosis. Long, (rostr. incl.) 

 4—5-5 mm. 



This species greatly resembles D. squalidzis Shp., and is often found in company 

 with that species, but is certainly distinct. The interstices of the elytra are never 

 covered with the whitish bloom as in that species, and the minute punctures which they 

 bear give rise to short pale-coloured setae. The % is readily distinct from that of 

 D. sqtialidiis by the fact that the rostrum has an evident, though not coarse, punctura- 

 tion on its anterior shining portion. Like most of the Hawaiian species this varies 

 considerably, but it is by no means improbable that I have included more than one 

 species under the above name. The raised apical margin of the elytra is continuous 

 with the sixth interstice as in D. squalidus. 



Hab. Found on all or nearly all the islands of the group. 



(3) Dryophthorus peles, sp. nov. 



Niger, robustus, grosse punctatus. Rostri % pars praeantennalis nitida, subtiliter 

 sat evidenter punctata. Pronotum latum, grosse punctatum, antice fortiter constrictum. 

 Elytra fortiter seriatim punctata, interstitiis distinctissime punctulatis, brevissime pallide 

 setulosis, haud cinereo-sericeis, margine apicali elevato cum interstitio sexto continuo. 

 Long, (rostr. incl.) 6 — 6 '5 mm. 



This species somewhat resembles D. distingttendus, but it is altogether larger and 

 more robust. The interstitial puncturation of the elytra is larger, and more distinct and 

 definite than in most of the species. The punctures in each row are closely set, and the 

 spaces dividing one from another are more than usually convex, grooved on each side 

 where they meet the interstices. This convexity gives them a strongly marked knob- 

 like appearance in certain aspects. The whitish bloom seen in D. squalidus is entirely 

 absent, but the interstitial punctures bear excessively minute pale setae. The interstices 

 themselves are all of nearly similar height, and the sixth is confluent with the elevated 

 apical side-margin. 



Hab. Hawaii. Kilauea (June 1895). Half-a-dozen examples, no doubt obtained 

 in a batch, as they stand under the same number. The species appears to me to be 

 most closely allied to D. nesiotes.
