California (middle coast regions). 



The male has the fifth ventral unmodified, the genital segment 

 small, short, pale and coriaceous, trapezoidal, with the apex feebl}' 

 emarginate throughout the width, the bottom of the emargination 

 broadl}' straight and transverse ; the copulator}- sheath is rather 

 less densel}' corneous than usual, dorsally it is gradually narrowed 

 to an obtuse and simple point, Avith the surface impressed along 

 the median line except near the apex, widely excavated along the 

 under surface, straight in profile but narrowed near the distal ex- 

 tremity above and beneath, the prolongation being feebly swollen 

 toward its rounded apex. This species occurred in large numbers 

 at Gilroy Springs, together with jyunctulatiis, and there is no dis- 

 cernible variability. 



86. A. !>«aticiil!ii 11. sp. — Somewhat stout, convex and dull, hlack, the legs 

 and antenuif tlirou<ihout and, on each elytron, a large oval spot at basal fourth 

 and another, large but rounded, at apical fourth, rufous; pubescence rather 

 dense, cinereous, short, clavate and recurved everywhere on the upper surface 

 except toward the front of the head and narrowly along the elytral suture, 

 where the hairs become longer and simple. Head as long as wide, thick and 

 convex, truncate and medially impressed at base, the angles broadly rounded; 

 eyes large and prominent, the tempora scarcely as long and feebly convergent 

 behind them; disk finely but rather closely punctate, the smooth line not dis- 

 tinct toward base; antennaj fully as long as the head and prothorax; strongly 

 incrassate, the tenth joint about as long as wide. Proihora.r distinctly nar- 

 rower than the head, as long as wide, convex, obtusely constricted at basal 

 fourth, somewhat finely but deeply, densely punctate. Elytra large, three- 

 fourths longer than wide, distinctly more than twice as wide as the prothorax, 

 broadly rounded behind, the sides parallel and feebly arcuate; humeri widely 

 and transversely exposed at base; omoplates subobsolete; punctures dense and 

 deep, moderately large. Abdomen alutaceous, minutely aud densely punctate. 

 Legs somewhat long and slender. Length 3.0 mm. ; width 1.1 mm. 



Iowa (Keokuk). 



Tlie sexual characters of the male are simple, the copulatory 

 sheath being elongate, parallel, graduallj^ narrowed in apical 

 third to a very olitusely rounded and simple point, the surface 

 unusually flat, perfectl}' straight and thin in profile, excavated 

 throughout its length beneath. A single male. 



37. A. Tiilnei'atu§ n. sp. — Subparallel, strongly depressed, dull, black 

 or piceous-black; abdomen pale toward tip; legs throughout pale tlavate; an- 

 tenme ruf o-testaceous ; each elytron with a large elongate-elliptical testaceous 

 spot at basal fourth, and another raucli smaller and rounded at apical fourth; 

 pubescence of the elytra short, even, dense, coarse but not clavate, of
