CERAMBYCID^E 363 



wide, bitruncate, with the sides feebly arcuate, becoming rather 

 fuller behind the middle, the surface strongly granose and much 

 more coarsely so in the female than in the male. The head is 

 nearly as in undulatus in both sexes, minutely sculptured and dull 

 in the male, excepting a narrow shining basal band, extending 

 forward in a fine line bordering the eyes internally and coarsely 

 punctate, almost uniformly and more coarsely punctato-rugose 

 throughout in the female. It is a very clearly circumscribed group, 

 containing several species and subspecies as follows: 



Body more rhombiform, very convex, with the elytra tapering very 

 rapidly from base to apex, dark red-brown in color throughout; 

 head well developed, the frontal carinse low and rather ill-defined, 

 separated by much more than the distance between either and the 

 supra-antennal carina, the vertex behind the line of the antennae 

 not carinulate medially; antennae (d 71 ) fully one-half as long as the 

 body, the third joint distinctly longer than the first, the outer joints 

 feebly canaliculate on their under surface nearly to the base; pro- 

 notum uniform in sculpture and vestiture, having numerous sharp 

 transverse granules and short, sparse, inconspicuous and subde- 

 cumbent pale hairs, also a few that are longer and erect; scutellum 

 less than twice as wide as long, arcuato-truncate at apex; elytra 

 distinctly wider than the prothorax, slightly more than twice as 

 long as wide, strongly, closely punctate, the punctures transversely 

 confluent, the marginal pale and sparsely pubescent line with two 

 small offsets opposite the offsets of the sutural line but not very well 

 developed; under surface uniformly and sparsely punctulate, 

 coarsely pilose; legs long, the femora notably stout, very sparsely 

 punctate and pilose, scarcely more than attaining the elytral tips 

 in the male. Length (cf) 17.5 mm.; width 4.9 mm. Florida. 



sagittatus Germ. 



A Similar to sagittatus but smaller, more slender, the elytra less 

 strongly tapering, relatively more elongate and with the punctures 

 more clearly defined and less coalescent; head with the frontal 

 carinse fine and sharply defined, exactly trisecting the space be- 

 tween the supra-antennal carinae; antennae more slender and notably 

 shorter, the third joint longer than the first, the canaliculation of 

 the outer joints shorter and more apical; vertex with a fine shining 

 carina extending almost to the base; elytra only slightly wider 

 than the prothorax; scutellum more than twice as wide as long, 

 circularly rounded; pronotum with smaller and closer transverse 

 carinules and with more numerous erect bristling hairs; legs 

 shorter, the femora much more slender, the posterior not attaining 

 the elytral tips. Length (cf) 12.0 mm.; width 3.2 mm. Penn- 

 sylvania pubescens Hald. 



Body more slender, much less rhombiform, the pale pubescence coarser 

 and much longer, frequently sprinkled over the entire surface
