collected in Vancoicver^s Island. 381 



The scape of the antennae is slender and extends to the back 

 part of the eves ; the funicukis is slender, and longer than the 

 scape ; the first and second joints are equal and elongate, the 

 third is two-thirds as long as the second, the fouiih, fifth, and 

 sixth equal, each a little shorter than the third, the seventh a 

 little longer ; club elongate-oval, acute at tip. The first ven- 

 tral suture is distinct and straight, the second and third are 

 deeply exarate; the last ventral segment is convex towards 

 the tip, and the extreme tip is carinated and acute. 



In D. sejnis the third joint of the funiculus of the antenna? 

 is scarcely shorter than the second, the carina of the rostrum 

 is very feeble, almost obsolete, and the lateral oblique lines 

 below the antennal grooves are entirely wanting. 



Dyslobus decoratus. 



Niger, squamis obscure argenteis et cupreo-fuscis variegatus, parce 

 breviter pubescens, rostro subcarinato ; tborace latitiidine haud 

 loiigiore, antice subangustato, lateribus rotundatis, apice basique 

 fere truncatis, angulis omnibus obtusis, disco transversim conveso, 

 profunde rugose punctate et granulato ; elytris thoraco latioribus, 

 elongato-ovalibus, apice rotundatim valde decbvibus, striis e 

 pimctis magnis magis approximatis compositis.

Vancouver's Island. 



Smaller and somewhat more robust than D. granicolUs^ but 

 apparently congeneric with it ] the carina of the rostrum is 

 more feeble, and does not end in an anterior elongate fovea ; 

 the lateral oblique lines below the antennal grooves are dis- 

 tinct ; the funiculus of the antennae is rather stouter, and the 

 third joint is not longer than the following, which are nearly 

 as broad as they are long ; the elytral stria? are feebly impressed 

 and composed of more approximate large punctures. 



Two other species of this genus are before me — one from 

 Oregon, one from California, which await description when a 

 general synopsis of the Curculionida? of the United States is 

 prepared. 



Tyloderes ? gemmatu^, Lcc. 



is related to Dyshhus^ but differs by the beak being more 

 slender, much more dilated at tip, and by the antennal grooves 

 being longer and deeper. The first and second joints of the 

 funiculus are elongate, the tliird to the seventh are nearly equal 

 in length, except that the fifth is a little shorter. The postocular 

 lobes of the prothorax are equally broad, but more prominent 

 and less fimbriate. The first ventral suture is deep, and feebly 

 convex forwards at the middle ; the other three are straight
