sparsely spaced along the beading; punctures not coarse but very 

 distinct, partially arranged in rather impressed series, which are 

 more close-set, unimpressed and more coarsely punctate toward the 

 sides, finer postero-laterad; pygidium about one-half wider than long, 

 triangular, having the lower angle broadly rounded, the surface 

 rather convex, shining, very finely, sparsely punctate, subrugulose 

 laterad; abdomen impunctate, excepting a single entire transverse 

 line of setigerous punctures on each; hind tarsi slender, distinctly 

 longer than the tibiae, which are much shorter than the femora. 

 Length (9) 13.7 mm.; width 7.7 mm. Mexico (Durango City), 

 Wickham *nubeculina n. sp. 



Body less stout, shining, elongate-oval, strongly convex, pale brownish- 

 flavate, the legs and entire under surface still paler flavate; head 

 rufous throughout, or blackish, with the clypeus obscure rufous; 

 pronotum with two dark red-brown vittae, broader basally, parallel 

 internally, with the outer contour biemarginate, the sublateral dark 

 dot evident; scutellum pale, rather wider than long, with scattered 

 small punctures; elytra dark red-brown, with a pale flavate sublateral 

 vitta, the area thence to the sides nubilously blackish-brown except 

 basally; head (9 ) not quite half as wide as the prothorax, variably 

 punctate but rather strongly, the clypeus twice as wide as long, the 

 sides parallel and rounded basally, thence oblique and nearly straight 

 to the more arcuate and reflexed apex, which is about half as wide 

 as the base, shining but densely, confluently punctate, the suture 

 strongly sinuate at the middle; eyes well developed; antennal club 

 not as long as the six preceding joints; prothorax two-thirds or 

 more wider than long, the sides strongly, evenly arcuate, a little 

 more converging apically, the apical angles short but sharp, the 

 basal rounded; basal margin with a fine entire bead, but with the 

 bead broadly obsolete medially in another example; punctures 

 sparse, small but distinct, becoming larger though shallow laterally, 

 fine and sparse throughout in the second example; elytra slightly 

 elongate, about a fifth wider than the prothorax, parallel, with 

 arcuate sides and obtusely rounded apex; punctures strong, partially 

 in series; lateral margin (9) feebly arcuate for a short distance 

 at the middle, not otherwise modified; pygidium feebly punctato- 

 rugulose, subalutaceous, glabrous; sterna with rather fine, moderately 

 long, decumbent and not at all dense hairs. Length (9) 13.0-13.5 

 mm.; width 7.0-7.4 mm. Arizona (Douglas, Cochise Co.) [ Cyclo-

3 Elytra brownish-rufous, clearer flavate near the scutellum and broadly 

 toward the sides. Body stout, oblong-oval, convex, moderately 

 shining; pubescence of the elytra and pygidium (c?) persistent, 

 rather long and distinct, virtually wanting (9); head small, much 

 less than half as wide as the prothorax, rufous, sometimes blackish 

 basally, rather closely punctate, more sparsely (9), the clypeus 

 two-thirds wider than long, shorter in the female, in outline, sculp- 

 ture and apical reflexion nearly as in the preceding, the suture 

 distinct, strongly sinuate in about median half, less in the female; 

 antennal club (cf ) as long as the preceding six joints, or ( 9 ) much
