DYNASTIISLE 157 



clypeus, which is more transverse than usual, more than one-half 

 wider than long, trapezoidal, the sides feebly sinuate anteriorly, 

 the apex truncate, with broadly rounded angles, strongly reflexed; 

 surface strongly, coalescently punctured, impressed along the median 

 line and broadly toward the sides; suture fine but distinct, strongly 

 sinuate at the middle; antennal club strongly curved, longer than 

 the stem; eyes separated by evidently less than twice their width; 

 prothorax only one-half wider than long, the sides strongly rounded, 

 more converging anteriorly, the basal angles broadly rounded; 

 base arcuate, not margined except feebly near the sides; punctures 

 minute and very remote, more distinct and closer laterad; elytra 

 not quite one-half longer than wide, oval, circularly rounded in apical 

 two-fifths, more than a fourth wider than the prothorax; surface 

 subrugulose, finely, sparsely, sublineately punctate; pygidium 

 convex, scabriculate, with very few extremely short hairs basally; 

 hind tarsi not distinctly longer than the tibiae. Female similar but 

 with the elytra a little shorter and more broadly oval, the head and 

 also prothorax relatively smaller, the frontal suture less sinuate, 

 the prothorax shorter, the stronger basal bead only interrupted 

 medially; hind tarsi tapering, thickened basally, three-fourths as 

 long as the tibiae. Length (cf 9 ) 11.5-12.2 mm.; width 6.0-6.3 mm - 

 Arizona (Congress Junction), F. H. Snow. Three examples. 



prona n. sp. 



II Body elongate-oval, strongly convex, rather shining, pale brownish- 

 rufous; head (cf ) slightly more than half as wide as the prothorax, 

 with well separated punctures, rufous and rugose anteriorly; eyes 

 separated by fully two and one-half times their width; clypeus one- 

 half wider than long, the sides at first straight and feebly, then 

 straight and more strongly, converging, to the strongly reflexed 

 apex, the angles rounded; surface coarsely and deeply rugose 

 basally, feebly in the concave anterior part, feebly impressed along' 

 the middle; side margins fine and elevated; suture coarse, entire, 

 broadly, circularly sinuate medially; antennal club as in prona; 

 prothorax fully three-fifths wider than long, the sides parallel and 

 scarcely arcuate, rounding and converging in nearly apical half; 

 base evenly arcuate, with a thick entire bead; basal angles moder- 

 ately broadly rounded; punctures minute and remote, rather close 

 and strong near the sides; scutellum obtusely ogival, with strongly 

 rounded sides; elytra one-half longer than wide, more than a fourth 

 wider than the prothorax, the parallel sides arcuate; apex circularly 

 rounded in two-fifths; pygidium convex, transverse, with numerous 

 erect hairs basally; tibiae rather stouter than usual; hind tarsi 

 slightly though evidently longer than the tibiae. Length (cf ) 14.4 

 mm.; width 6.8 mm. California (the locality not definitely re- 

 corded). One specimen rustica n. sp. 



Form elongate, testaceous, shining; head sparsely punctate, nigrescent; 

 front testaceous; clypeus parabolic, subtruncate, the apical margin 

 strongly reflexed; prothorax sparsely punctate, somewhat narrowed
