COLEOPTERA 655 



Rostrum not densely nor coarsely punctate, apically at least strigose-punctate. 

 Pronotum broad, generally dull and very finely but distinctly punctured. Elytra with 

 the interstices conspicuously punctured, the punctures much more fine than the rather 

 coarse and deep serial ones. The antennae vary a little, the second joint usually 

 appearing stouter and shorter than the third, but when the basal constricted part of the 

 former is fully exposed, it is sometimes as long as the latter. Length 4-5 — 6 mm. 



Closely allied also to O. coj-ticis, but at once distinguished by the coarseness of the 

 serial punctures of the elytra. 



Hab. Maui ; Haleakala ; a common species, I believe, previously confounded with 

 the very abundant O. corticis of Maui, Molokai and Lanai. 



(2) Oodciuas fiazcancnse, sp. nov. 



Brassy, robust, the tibiae and tarsi testaceous, rostrum dilated apically, second and 

 third joints of the antennae subequal when the second is fully exposed. 



Allied to O. punctiilatissimuni of Oahu by the second joint of the funiculus being 

 much less elongate than is usual in the group of the genus, but very distinct by the 

 larger serial punctures of the elytra, which are coarse as compared with the very feeble 

 interstitial ones. The punctures in the series are remote, and the inner series tail at 

 about the middle of the length of the elytra or before this. There is no striation, 

 except posteriorly, where the interstices become convex. The eyes are hardly at all 

 convex. Length about 3 '5 mm. I have not seen the male of this species. 



Hab. Hawaii, Mauna Loa at 4000 ft. Probably common, but overlooked. 



Orothreptes callithrix Perkins. 



O. callithrix Perkins, huj. op. 11., p. 147. 



Originally described from Kona, Hawaii, this species has now occurred on mount 

 Tantalus near Honolulu. Though I did not take many specimens, I found it quite 

 common in the month of November. It will probably be found on the other windward 

 islands. 



Hab. Hawaii. Oahu ; mount Tantalus, not rare. 



Pentarthrnin blackburni Sharp. 



Pentarthruin blackburni Sharp, huj. op. 11., p. 147. 



On several occasions I have seen imported boxes, with the wood largely destroyed 

 by a Pciitarihntiu, which appears to be the above species. It is no doubt an imported 

 insect.
