22 Mr. D. Sharp's descriptions of some neiv species 



sidered an entirely isolated group, and should be placed 

 at the commencement of the Rhyncophora, being Avidely 

 distinguished from Leconte's series Haplogastra by the 

 minute, embedded and globose front coxae, by the more 

 rudimentary trophi, and by the subtetramerous tarsi. 

 Though the two species of Agh/cyderes Avould not, from 

 their facies at first sight, suggest a proximity with Rliino- 

 maceridce. as a natural position for the family, this difficulty 

 is removed by an inspection of the male of Proterhinus, 

 which has, perhaps, more the appearance of a Rldnomacer 

 than of any other insect. 



Dryophthorus squalidus, n. sp. Piceus, vel fusco- 

 niger, opacus ; prothorace subconico, antrorsum leviter 

 constricto, jequali, dense fortiterque punctato ; elytris sat 

 elongatis, subparallelis, thorace paululum latioribus, sat 

 profunde striatis vel sidcatis, striis fortiter punctatis, in- 

 terstitiis tequalibus, planis, hand velutinis, 6° ad apicem 

 sat cariuato-elevato ; metasterno elongato. Long. 3| — 

 4| mm. (exc. rost.) 



In the male the rostrum is punctured and opaque till 

 just before the apex, where there is left a transverse smooth 

 space ; in the female the rostrum is longer, and all the 

 portion of it in front of the insertion of the antenna is 

 smooth. 



The species is a good deal larger than the European 

 Dryophthorus lymexylon, and the thorax is broader, with 

 a much less distinct constriction in front : the sculpture is 

 very similar, except that the interstices are broader in 

 D. squalidus. 



]Mr. Blackburn says this is the commonest species in 

 Oahu, and occurs at a lower elevation than most of the 

 others. 



Dryophthorus gravid us, n. sp. Robustus, niger, vel 

 piceus, opacus ; prothorace antrorsum angustato, lateribus 

 rotundatis, antrorsum leviter constricto, dense grosseque 

 punctato, fequali ; coleopteris latis, haud elongatis, pro- 

 thorace evidenter latioribus, grosse seriato-punctatis, inter- 

 stitiis ad basin nullo modo elevatis, ad a})icem declivam 

 evidenter (prassertim secundo) carinatis, 6° versus apicem 

 carinato-elevato ; metasterno haud elongato. Long. 5 — 

 5 1 mm. 



I have seen four specimens of this species ; its very
