CERAMBYCID^E 297 



Form more slender, the elytral fasciae extremely nubilous and faint or 

 wanting 4 



4 Color pale reddish-brown throughout; antennae very pale, with the 

 basal joint not decidedly darker and bristling throughout with stiff 

 short setae; punctures of the head rather strong, deep and moderately 

 close, of the prothorax slightly smaller and dense, of the elytra rather 

 coarse, well separated, becoming rugose toward the humeri, the 

 vestiture of the elytra very short, rather coarse, dense, feebly and 

 indefinitely mottled with pale brown, almost entirely so basally, and 

 with a very feebly defined entire transverse fascia of the same near 

 posterior third. Length (9) 20.7 mm.; width 5.9 mm. New 

 Jersey pulverulentus Hald. 



Color darker brown, the prothorax and legs partially blackish; antennae 

 very pale, with the basal joint much darker and more evenly and 

 sparsely punctate and pubescent than in the preceding; head strongly, 

 very deeply and closely punctate throughout; prothorax more strongly 

 and deeply punctate than in pnlvcridentns and with two small sub- 

 anterior ill-defined areas, which are less coarsely, densely punctured 

 and not visible in that species; scutellum more impressed medially; 

 elytra with coarser and perforate, less widely spaced punctures, 

 denser posteriorly, more feebly rugose at the humeri, clothed more 

 sparsely but more evenly throughout with short whitish pubescence, 

 which is everywhere faintly mottled with more condensed irregular 

 spots of the same tint; tarsi but feebly dilated. Length (c? ) 18.0 

 mm.; width 5.2 mm. New York (Bluff Point, Lake Champlain). 



laurenticus n. sp. 



5 Form rather narrow, convex, densely punctate, the punctures of the 

 elytra well separated and in part subserial in arrangement, blackish, 

 the hind body, legs and antennae throughout pale, the basal joint 

 pubescent and moderately herissate; head, prothorax and nearly 

 posterior third of the elytra with dense uneven yellow pubescence, 

 the remainder of the elytra with white and dark brown pubescence, 

 the latter forming two uneven broad fasciae, near basal third and 

 just behind the middle; tarsi slender. Length (cf 1 9 ) 1 1.5-12.3 mm. ; 

 width 3.2-3.6 mm. Illinois and Pennsylvania (the elytral punctures 

 closer 'and less serial in the latter example) debilis Lee. 



There is a distinct difference in elytral punctuation between the 

 western males of debilis at hand and the single old and more or less 

 imperfect male from Pennsylvania, but there is not sufficient 

 material upon which to form any certain opinion. The single 

 male of laurenticus was obtained by the writer by beating from 

 some low bushy trees near Plattsburg, during the past summer; 

 it has quite a different general habitus from pulverulentus, due to its 

 smaller size, coarser and closer elytral punctures and more uniform 

 vestiture.
