CERAMBYCIM: 253 



2 Head and prothorax relatively rather large, the latter much wider 

 than long and very coarsely, closely punctate; elytra with the 

 punctures relatively only moderately coarse, close-set throughout, 

 each elytron with two very feeble discal riblets; body black in color, 

 the elytra obscure rufous throughout; testaceous part of the outer 

 antennal joints short and nubilous. Length (9) 11.5 mm.; width 

 4.2 mm. Kansas dehiscens Lee. 



Head and prothorax relatively much smaller, the latter fully as long as 

 wide to a little longer; elytra more rapidly narrowed from the 

 base, still shorter and apically more dehiscent, very coarsely punctate 

 basally, rapidly less coarsely apically 3 



3 Male with the last ventral simply feebly impressed medially, the 

 impression not limited laterally by prominent sides, though with 

 the usual apical emargination and prominent acute angles 4 



Male with the last ventral more broadly and apically, more or less 

 deeply excavated, the depression bounded laterally by acutely 

 elevated margins, which posteriorly, form part of the acute apical 

 angles 5 



4 Body deep black, rather shining, the elytra black, with a broad 

 dusky rufous vitta along the summit of the flanks from the humeri 

 to the tips; pubescence not conspicuous, erect anteriorly, short and 

 inclined on the elytra; head very densely punctate and dull; eyes 

 (c?) large, separated by twice their widths, the tempora very oblique 

 and retracted as usual; antennae four-fifths as long as the body, simi- 

 lar in the sexes; prothorax very convex, parallel, obliquely narrowed 

 anteriorly, coarsely, deeply and closely punctate, with narrow shining 

 interspaces; elytra one-half wider than the prothorax, two-thirds 

 longer than wide, the apices very obtusely rounded; punctures very 

 close-set and without lineal arrangement; last ventral segment (c?) 

 smooth and barely at all punctate, the medial impression very 

 feeble and indefinite. Length (cf 9 ) 9.5-10.0 mm.; width 3.0- 

 3.5 mm. Wisconsin (Bayfield), Wickham; also Ontario. 



cuneatula n. sp. 



5 Head with the punctures rather small and very densely crowded, 

 giving an opaque appearance; eyes (cf ) separated by barely twice 

 their width; antennae nearly as in the two preceding species; pro- 

 thorax very convex, with the herissate vestiture unusually obvious, 

 the punctures close-set or dense, rather coarse (c?) or less so (9 ) ; 

 sides almost evenly converging and broadly arcuate from base to 

 apex; elytra two-fifths wider than the prothorax, short and very 

 rapidly cuneiform, the apices narrowly and arcuately subtruncate; 

 external outline posteriorly notably sinuate (cf), or feebly arcuate to 

 the tip (9), the punctures very coarse, deep and close basally, 

 sometimes with traces of lineal arrangement postero-externally, 

 pale red-brown throughout in specimens at hand. Length (cf 9 ) 

 7.5-9.0 mm.; width 2.5-3.2 mm. Northeastern States and Canada.

Head with the punctures larger, not so crowded, the lustre not opaque. .6 



6 Black, somewhat shining; elytra pale red-brown, the suture infuscate 

 in the type from near the scutellum to the apices, which are nar-
