alytfit with deep punctured striae; interstitial lines hardly broader than tb« 

 striae and each with a single series of rounded punctures; anal tip naked.dense" 

 If punctured." pectus slightly indented .• anterior feet not very distant. 

 Length one fifth of an inch. 



This is the true striatus of Melsheimer's Catalogue ; the following speciei 

 which I formerly confounded with it, is different. 



6. B. inter stitialis, Nob. (Rynchaenus) Journ. Acad. Nat. Sc. 3,p. 314. 

 Much like the preceding, but the thorax is more rounded, being more abruptly 



contracted before & the punctures are much smaller. The interstitial lines are 

 broader & their punctures have a transverse rugulous appearance. 



7. B. transversus, Thorax at thescutel obtusely iobed ; scutel transverse. 

 Inhab. Missouri. 



Body black, punctured : head transversely indented between the eyes : an* 

 fennae obscure piceous, inserted beyond the middle of the rostrum ; third 

 joint but little longer than the fourth : club ovate : thorax rather abruptly con-> 

 tracted before ; punctures numerous, rather dense ; middle lobe of the base 

 very obtusely rounded: eZy^ra with deep, punctured striae; interstitial lines 

 with close set, almost confluent punctures ; third line with more than one se- 

 ries ; exterior & posterior edges piceous : tibiae a little tinged with piceous : 

 anal seg-meiit naked , punctured. 



Length over one fifth of an inch. 



In the form of the thorax it resembles interstiliaJis, Nob. but the punctures 

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

 interstitial lines are rounded.

L C. anaglypicus. Thorax bilineate each side ; elytra with elevated lines ; 

 » fulvous spot on each at base.

£ody blackish piceous, punctured ; eyes small ; antennae piceous ; rostrum 

 eulcated ; ^/joraa;lobed at the eyes; subinequal, somewhat rugose; two whitish 

 longitudinal lines on each side divergingbefore & behind with numerous minute 

 cinereous hairs, & withjtwo or three oblique uniting lines .- elytra triangular 

 much wider at base than the thorax & sub acute at tip, each with four eleva- 

 ted acnte striae,the exterior ones united at tip,- interstitial grooves dilated - con- 

 e&ve, with a double series of transverse punctures, an oblique, fulvous, oval Bpot 

 at the humeral base, tip brown ; epipleura a series of punctures, base hirsute 

 with a double series ; /ee? varied with cinereous hair ; thighs with arobustj 

 prominent'spine beneath near the middle, 6c a smaller one nearer the tip. 



Length from the front to anus less than one fifth of an inch. 



Found many specimens ascending a hickory tree (Juglans) in the fruit of 

 which they deposit their eggs, in thejlatter part of June & beginning of July. 



2. C, elegans, Piceous brownish ; elytra with a paler, more or less dilated 

 space behind.

 sulcated, carinate, piceous': antennae sufous : thorax \ohed at the eyes ; punc- 

 tured ; an obsolete, oblique, cinereous line each side preceding to the posterior 

 angles: eZy<ra with four somewhat elevated, acute lines, the exterior one« 

 uniting behind ; interstitial spaces wide, with double series of punctures, ob- 

 solete behind ; behind the middle is a more or less dilated common space, nar-
