282 CURCULIONIDES. 



dented between the eyes antennae dark piceous, inserted beyond 

 the middle of the rostrum ; second joint rather long; third not 

 . er than the fourth; club obtuse; thorax subconic with ap- 

 proximate orbicular punctures and a glabrous middle line ; basal 

 edge deeply sinuous [ 18 ] elytra with deep punctured striae; in- 

 terstitial lines hardly broader than the striae and each with a 

 single series of rounded punctures : anal tip naked, densely punc- 

 tured : pectus slightly indented : anterior feet not very distant. 



Length one-fifth of an inch. 



This is the true striatus of Melsheimer's Catalogue ; the follow- 

 ing species which I formerly confounded with it, is different. 



6. B. interstitialis nob. (Rt/nchsenus) Journ. Acad. Nat. 

 So. 3, p. 814. 



Much like the preceding, but the thorax is more rounded 

 being more abruptly contracted before and the punctures are 

 much smaller. The interstitial lines are broader and their punc- 

 tures have a transverse rugulous appearance. 



7. B. trans versus. — Thorax at the scutel obtusely lobed ; 

 scutel transverse. 



Inhabits Missouri. 



Body black, punctured : head transversely indented between 

 the eyes : antenn83 obscure piceous, inserted beyond the middle 

 of the rostrum; third joint but little longer than the fourth: 

 club ovate : thorax rather abruptly contracted before ; punctures 

 numerous, rather dense ; middle lobe of the base very obtusely 

 rounded : elytra with deep, punctured striae ; interstitial lines 

 with close set, almost confluent punctures ; third line with more 

 than one series ; exterior and posterior edges piceous : tibiae a 

 little tinged with piceous : anal segment naked, punctured. 



Length over one-fifth of an inch. 



In the form of the thorax it resembles interstitialis nob., but the 

 punctures are much larger, the posterior lobe is more rounded, 

 and the punctures of the interstitial lines are rounded.

 I. C. ANAGLYPTicus. — Thorax bilineate each side ; elytra with 

 elevated lines; a fulvous spot on each at base. 

 Inhabits United States.
