and a new genus of Rhyncophorous Coleoptera. 23 



robust build, and large size, and the rows of very coarse 

 punctures on the elytra, the interstices of which, on the 

 basal portion, are not in the least elevated, will readily 

 distinguish it. The sexual differences are much the same 

 as in Dryophthorus squalidus. 



Dryophthorus crassus, n. sp. Robustus, piceiis, opacus ; 

 prothorace antrorsum angustato, lateribus rotundatis, an- 

 trorsum sat constricto, fortiter punctato, a^quali ; coleopteris 

 latis, haud elongatis, prothorace latioribus, minus pro- 

 funde sulcatis, sulcis fortiter crenato-punctatis, interstitiis 

 paululum elevatis, lutosis, latis, 6° versus apicem acute 

 carinato - elevato ; metasterno haud elongato. Long. 

 4^ — 5^ mm. 



This species, on account of its large size and heavy 

 form, resembles Dryophthorus gravidus, but the differ- 

 ence in the sculpture of the elytra renders the two species 

 quite easy to distinguish. I have seen a single pair, the 

 sexual distinctions being the same as in the preceding 

 species. 



Dryophthorus declivis, n. sp. Piceus, opacus; pro- 

 thorace antrorsum fortiter constricto, lateribus minus 

 rotundatis, dense fortiter punctato, inasquali ; coleopteris 

 haud latis, sed prothorace evidenter latioribus, versus 

 apicem planato-declivis, fortiter seriato-punctatis, inter- 

 stitiis 2°, 4°, 6°que elevatis, 6° versus apicem alte carinato ; 

 rostro ad apicem fortius bidentato. Long. 3^ mm. 



Rare ; I have seen only two males ; they have the ros- 

 trum very rugose except just at the tip. The form of the 

 apical portion of the elytra reminds one somewhat of the 

 Tomicides ; both the fourth and sixth interstices coalesce, 

 to form the acutely-raised apical margin. 



Dryoj)hthorus modestus, n. sp. Subgracilis, nigricans, 

 opacus ; prothorace subcylindrico, antrorsum evidenter 

 constricto, dense fortiterque punctato, disco vix in^equali ; 

 elytris haud elongatis, prothorace paululum latioribus, 

 evidenter sulcatis, sulcis sat fortiter crenato-punctatis, . 

 interstitiis latis, a?qualibus, minus elevatis ; margine apicali 

 sat elevato, cum interstitio quarto conjuncto. Long. 

 3 mm. 



This species is just about the size of Dryophthorus 

 lymexylon ; the thorax is broader in comparison with the 

 elytra, and the interstices of the elytra are broader than
