P. castauea, n. sp. — Body parallel, moderately and evenly convex, 

 rather stout in build, strongly shining, with a feebly alutaceous or sub- 

 opalescent lustre, very dark blackish-castaneous above, less dark and more 

 rufo-castaneous beneath ; head large, transversely trapezoidal, smooth, 

 with a few very fine scattered pubiferous punctures toward the base of the 

 vertex, the occiput smooth ; prothorax fully twice as wide as long, feebly 

 trapezoidal, with almost evenly and moderately arcuate sides ; apex and 

 base truncate, the latter arcuate laterally, the basal angles rounded ; sur- 

 face sparsely punctate throughout, very finely medially, less so and more 

 asperately laterally, the punctures medially bearing very short erect stiff 

 hairs, becoming longer but still very short laterally, the sides explanate, 

 concave, except basally ; scutellum polished, transversely triangular ; elytra 

 one-half longer than wide, not quite as wide as the prothorax, the sides 

 straight and parallel, broadly rounding at the humeri and becoming feebly 

 convergent in less than apical third to the broadly-rounded external angles, 

 the apex broadly arcuato-truncate, the sutural angles rounded ; surface 

 evenly convex, each with nine even unimpressed series of small asperate 

 punctures bearing stiff erect seta 1 , the punctures subequal throughout, 

 except the ninth and a partial tenth series on the flanks, which are very 

 minute and barely traceable; there is also a partial basal series between 

 the first and second ; fine, acute lateral margins with a series of close-set 

 asperate setigerous punctures on and not wiihin the edge itself; first 

 abdominal suture abruptly arcuate at the middle, the second segment, and, 

 to a less degree, the third and fourth finely and closely punctate, and with 

 short decumbent fulvous pubescence except laterally, and also with a 

 single irregular transverse series of fine close setigerous punctures. Length, 

 9.8 mm.; width, 4.0 mm. Utah (Stockton). 



This species may be placed near the Arizonian angustata, Horn, — 

 printed in table, text and over the original description "augustata" ; but 

 presumably angustata is meant. It differs, however, in the absence of 

 any indication of the subsutural row of larger punctures characterizing 

 that species and in its decidedly larger size.

 The following appears to be a form worthy of a name, though closely 

 related to parallelus : 



D. nanus, n. subsp. — Similar in form, coloration and general structure 

 to parallelus, but very much smaller and differing ( $, ), in having the head
