2l8 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [BuU. 



pygofers, length one-third greater than width, outer margins 

 rounded, exceeded by ovipositor one-fourth their length. Male, 

 last ventral segment weakly convex, length slightly less than basal 

 width, narrowing apically ; plates long, tapering processes, length 

 one-half greater than basal width, outer margins sinuate, inner 

 margins fused in basal third, thence attingent until just before 

 black tips, where they narrow slightly and diverge. 



Color : Varying tawny, punctured with darker ; spot either side 

 of tylus, median carina throughout entire extent, anterior half of 

 pronotum, and angles of scutellum, lighter ; an oblique, broad band 

 from scutellum to costal margin, another shorter and more obscure 

 behind it, and a marginal spot at base of costa, dark brown variably 

 margined with whitish. 



Distribution : Specimens have been examined from Washington, 

 Oregon, Colorado, and Montana. It has been reported from 

 Vancouver's Island and Idaho (Ball), and from Utah (Uhler). 

 A. saratogensis (Fitch). (PI. iv, 28.) (Fig. 19, 29-32.) 



Lepyronia saratogensis Fitch. Cat. Hom. N. Y., 53, 185 1. 



Ptyelus detritus Walker. List Hom. Brit. Mus., 713, 1851. 



Ptyelus gelidus Walker. List Hom. Brit. Mus., 714, 1851. 



Color deep fulvous, a broadening median stripe from anterior 

 margin of tylus to base of scutellum, and elytra obliquely banded 

 with light; form narrow and elongate, front scarcely inflated, 

 apex of elytra acutely angulate. Length 8.5-iimm. ; width 

 3-4 mm. 



Vertex, length on middle one-third greater than at eye, disc 

 elevated in median line, bluntly carinate, anterior margin from 

 eyes to tylus nearly straight; tylus, length one-third width, disc 

 flattened ; front small, scarcely inflated, angle with vertex very 

 acute; pronotum, disc weakly convex, transverse depressions 

 before middle slight, carina weak except across depressed area, 

 where it appears as a blunt elevation, lateral margins parallel; 

 elytra long and narrow, costal margins scarcely reflexed, apex 

 sharply, acutely angulate. 



Genitalia : Female pygofers long, length one-half greater than 

 width, exceeded by stout ovipositor almost one-half their length. 

 Male, last ventral segment very short, convex, laterally tooth- 

 notched on posterior margin ; plates subquadrate, fused, medially 

 notched to one-third their depth at apex, outer margins produced, 

 broadly rounded behind. 



Color: Varying fulvous to grayish-brown; vertex and prono- 

 tum darker, with a broadening median light stripe from anterior 

 margin of tylus to base of scutellum ; elytra lighter, usually with 

 distinct light bands running obliquely from the scutellum to costal 

 margins, in obscurely marked specimens the banded area of the 

 disc appearing mottled with light gray. 



Distribution: Specimens have been examined from the New 

 England States, New York, Maryland, District of Columbia.
