with some coarse punctures about fovea near eye; pale, with usually 

 a small spot in middle of occiput, the tubercles frequently brown and 

 the labrum always dark. Antennae short, dark with paler basal 

 joints. Prothorax a little more than twice as wide as long, somewhat 

 convex, a little narrowed anteriorly, with sides arcuate; surface more 

 or less distinctly and quite densely punctate, alutaceous; pale, with 

 two anterior dark spots not close together and somewhat oblique. 

 wScutellum dark. Elytra broadly oblong oval, convex, with humeri 

 not prominent and without intrahumeral sulcus; surface alutaceous, 

 somewhat shining, densely and often coarsely punctate; sutural, 

 median and submarginal vittae only moderately wide, the submarginal 

 one uniting with sutural at apex. Body beneath usually finely and 

 densely pubescent, but in Arizona specimens only sparsely pubescent; 

 entirely pale, the apex of tibiae and tarsi brown, and sometimes the 

 middle of the anterior femora with a brown marking. Length 4.6 

 to 6.5 mm., width 2.6 to 3.2 mm. 



Type: Female, USNM 49225 (Casey collection), from Arizona, 

 collected by H. K. Morrison. 



Other localities: United States: From Maine to Ai'izona. It 

 has been taken in shipments from Mexico: one in purslane and another 

 on vegetables, both taken at El Paso, Texas, and a third in a Selaginella 

 plant from San Miguel de Guanajuata, taken at Laredo, Texas, 



Remarks: It may be that this species occurs commonly in Mexico 

 although only the three specimens recorded above are known from 

 there. The Biologia material labeled "N. Sonora, Mexico," Morrison 

 collector, is really from Arizona. As stated in my earlier revision, 

 this last was identified as D. glabrata (Fabricius), presumably by 

 Jacoby.

Figure 35 



About 5 mm. in length, oblong oval, shining although finely aluta- 

 ceous ; pale yellow; the head with a dark occipital spot and usually dark 

 tubercles and labrum; pronotum with two small spots anteriorly and 

 traces of a median and sometimes two faint lateral spots; elytra with 

 narrow sutural, median, and submarginal vittae not joined at apex; 

 body beneath pale, with the tibiae and tarsi tending to be deeper 

 brown. 



Head elongate, the interocular space more tliaii half the width of 

 head, a somewhat produced moderately wide carina, the area under the 

 antennal sockets deeply excavated, upper vertex with coarse punctures 

 on either side, sometimes nearly across front, a dark spot on occiput, 

 tubercles and also labrum tending to be dark. Antennae short and
