24 Mr. D. Sliarp's descriptions of some neiv species 



in the European species. I have seen only males of this 

 species ; according to Mr. Blackburn it is rare, and has 

 been found by him in the stems of a species of fern in 

 Oahu. 



Note. — The sculpture of the species is very much 

 that of D. squalidus ; but independently of its much 

 smaller size the present is readily distinguished therefrom 

 by the fact that the apical side margin of the elytra is 

 connected with the fourth interstice instead of the sixth. 



Dryoplithorus pusillus, n. sp. Subgracilis, nigro- 

 ferrugineus, opacus ; prothorace subcylindrico, antrorsum 

 evidenter constricto, dense fortiterque punctato, disco vix 

 injequali ; elytris hand elongatis, prothorace paululum 

 latioribus, sat profunde sulcatis, sulcis .minus conspicue 

 crenato-punctatis, interstitiis vix latis, subtequalibus ; 

 margine apicali fortiter elevato, cum interstitio quarto 

 conjuncto. Long. 21 mm. 



This is the smallest Dryoplithorus Mr. Blackburn has 

 yet brought to light; he informs me it is found in the 

 mountains of Oahu and is not common. I have seen 

 only two males. It has the eyes more reduced than is 

 the case with the other species here described ; and may 

 also be readily distinguished from D. modestus by the 

 more acutely-elevated apical margin of the elytra. 



Dryoplithorus insignis, n. sp. Fuscus, opacus, grosse 

 pimctatus; rostro brevissime setuloso; prothorace antror- 

 sum profunde constricto, post constrictionem subquadrato ; 

 fortiter ruguloso-punctato, breviterque (ad marginem an- 

 te riorem dense) setuloso; coleopteris brevibus, latis, pro- 

 thorace evidenter latioribus, fortiter seriatim punctatis, 

 interstitiis 2", A", 6° valde carinato-elevatis et dense setu- 

 losis, 2°, 4°, que pone basin fere interruptis, ceteris 

 omnino inconspicuis. Long. 3 mm. 



This species is found in rotten wood at a considerable 

 elevation; it is so readily distinguished from the others 

 by its acutely-elevated alternate interstices of the elytra, 

 and by the almost total disappearance of the other inter- 

 stices, that it is not necessary here to allude more fully 

 to its other characters. I have received eight specimens 

 from Mr. Blackburn ; in all of them the rostrum is rugose 

 and opaque till very near the tip ; in some of them the 

 rostrum is a little more slender than in others; whether
