but little longer than the tibiae. Length (9) 10.8 mm.; width 5.9 

 mm. Iowa (Keokuk). A single example pagana n. sp. 



8 Tibiae rather stout. Body oblong-oval, moderately convex, shining, 

 pale castaneo-rufous in color; head (cf ) half as wide as the prothorax 

 to somewhat less, dark rufous, gradually black and finely, sparsely 

 punctate basally, more closely frontally; eyes separated by barely 

 more than twice their width; clypeus less than twice as wide as long, 

 trapezoidal, with rounded and feebly reflexed sides and arcuate, more 

 reflexed apex, the angles broadly rounded; surface densely punctate, 

 more convex medially as a rule, the suture feeble, inconstant; an- 

 tennal club a little longer than the stem; prothorax fully three-fourths 

 wider than long, the sides broadly rounded, converging at apex; 

 punctures sparse but distinct; scutellum sharply triangular, sparsely 

 punctulate, fully as wide as long; elytra slightly elongate, some- 

 what inflated posteriorly, obtusely rounded at tip and distinctly 

 wider than the prothorax, the punctures not coarse, rather sparse, 

 the geminate series evident; pygidium rather finely, closely punctato- 

 rugulose throughout, having basally a few short sparse hairs; 

 hind tarsi two-thirds longer than the tibia?. Female a little larger 

 and slightly stouter than the male but otherwise nearly similar, 

 except that the head, eyes and antennal club are much smaller, the 

 elytra perhaps a little more coarsely punctate, the pygidium glabrous 

 and finely, sparsely punctate; hind tarsi about as long as the tibiae. 

 Length (6 cf , 2 9) 11.4-14.2 mm.; width 5.9-7.4 mm. Southern 

 California pasadenae n. sp. 



Tibiae all notably slender as in immaculata, which the general habitus 

 imitates rather closely 9 



9 Head (cf 1 ) much more than half as wide as the prothorax. Body 

 pale brownish-yellow, the head black, sparsely punctate, the front 

 densely; eyes large, separated by rather less than twice their width; 

 clypeus rufous, much less than twice as wide as long, almost evenly 

 parabolic, except that the reflexed apex is rather feebly arcuate, the 

 surface densely punctate, the suture fine but very distinctly defined 

 throughout the width, deeply but broadly sinuate medially; antennal 

 club a third longer than the stem; prothorax three-fourths wider 

 than long, the sides rounded, less so and converging from rather 

 behind the middle to the apex; punctures fine but distinct and sparse 

 medially, strong and closer laterad; scutellum rather small, sparsely 

 punctate; elytra distinctly longer than wide, circularly rounding in 

 about apical two-fifths, slightly wider than the prothorax, the punc- 

 tures very shallow and feebly impressed; humeral umbo strong and 

 elongate; side margins finely punctate and with erect stiff hairs; 

 pygidium with some very short hairs basally; hind tarsi not so long 

 as usual, scarcely one-half longer than the tibiae in the male. Length 

 (2 cf ) 10.0-10.5 mm.; width 5.2-5.5 mm. Southern Arizona.
