CERAMBYCID^E 303 



elytra more than three times as long as wide, similarly coarsely 

 and closely punctate but with the punctures more rapidly smaller 

 and fine apically, the sparse vestiture but feebly and loosely 

 nucleated; fifth ventral nearly semicircular. Length (9) 12.0 

 mm.; width 2.5 mm. Canada (Ontario). .. canadensis n. subsp. 

 B Nearly similar to the preceding in general form but larger, piceous- 

 black, the elytra brighter testaceous, the legs and antennae dark 

 red-brown; antennae (9) two-thirds as long as the body, very 

 slender, finely, sparsely punctured basally, with moderate spines, 

 the third joint a little longer than the fourth and correspondingly 

 shorter than the first, which is more densely pubescent; prothorax 

 (9 ) about as long as wide, the sides parallel but broadly, feebly 

 angulate at or just behind the middle, dull in lustre, the punctures 

 much smaller than usual in the female and very dense, with a small 

 impunctate area behind the centre, the pubescence short, coarse, 

 closely decumbent, rather abundant, nubilously aggregated toward 

 the sides and along the median line anteriorly; scutellum moderate; 

 elytra parallel, more than three times as long as wide, two-fifths 

 wider than the prothorax, the sinus at the tips as in the preceding 

 but rather larger, the punctures but very little larger though much 

 deeper than those of the pronotum, well separated, smaller but 

 distinct apically; fifth ventral very broadly and feebly arcuate at 

 apex. Length (9 ) 14.5 mm.; width 3.1 mm. Florida. 



densicollis n. subsp. 



Male with the densely and finely punctate pronotum even, except a 

 narrow short impunctate line just behind the centre; elytral apices 



as in villosus 8 



8 Male with the fifth ventral broadly and evenly rounded. Body very 

 slender, parallel, pale red-brown, the elytra, legs and antennas rather 

 paler and testaceous; head with rather small, close punctures and 

 a flat glabrous impunctate median line posteriorly, becoming finely 

 impressed anteriorly; antennae (cf ) very slender, not quite as long 

 as the body, loosely and not coarsely punctate, with small spines, 

 the third joint slightly longer than the fourth and almost as long as 

 the first; prothorax slightly wider than long, the sides broadly but 

 sharply angulate at the middle, thence rather strongly convergent 

 and straight to the base and less convergent and also perfectly 

 straight to the apex, which is evidently wider than the base; surface 

 very finely, densely and evenly though shallowly and irregularly 

 punctate and dull, the pale yellowish hairs sparse but condensed into 

 a subeven narrow sublateral line, bending outward slightly, from 

 the apical margin to behind the middle, this line from the middle to 

 the base feebly subtumid, more coarsely punctate and again pubes- 

 cent at base; elytra parallel, more than three times as long as wide, 

 only very little wider than the prothorax, the punctures moderately 

 close and strong, smaller apically, the vestiture rather sparse, feebly 

 condensed. Length n.o mm.; width 2.4 mm. A single unlabeled 



male from the Levette collection defectus n. sp. 



Male with the fifth ventral truncate at apex 9 



9 Form slender, parallel, the coloration and sculpture nearly as in the
