shorter than in the male; prothorax three-fourths wider than long, 

 the rounded sides becoming subparallel in fully basal half, strongly 

 converging apically, the short apical angles sharp but more than 

 right, the basal only moderately rounded; fine basal bead obsolete 

 medially; surface sometimes indefinitely clouded in two large discal 

 spots, with the sublateral dark dot distinct; punctures not very 

 small, deep, distinct and only moderately sparse, only slightly larger 

 laterad; elytra short, but little longer than wide, only slightly wider 

 than the prothorax, obtusely rounded at apex; punctures rather 

 strong and close-set, uneven, partially in series, the geminate lines 

 impressed; lateral margin (9) not modified, having a very feeble 

 sinuation in both sexes near basal third; first four abdominal seg- 

 ments equal, short, each distinctly shorter than the fifth in both 

 sexes: larger claw of the anterior tarsi (cf ) unequally cleft at apex, 

 the slender ramus apparently broken off at the base in the single 

 male at hand. Length (cf 9 ) 11.0-15.0 mm.; width 6.0-8.4 mm. 

 California (San Diego). [Cyclocephala hirta Lee.] hirta Lee. 



Elytra paler flavate-brown, each with a narrow, very irregular oblique 

 brown vitta medially, which is very widely interrupted. Body 

 rather longer, oblong-elongate, strongly convex, rather shining, pale 

 .and uniform yellow-brown in color throughout, the outer edge of 

 the anterior tibia deep black as usual; head less than half as wide 

 as the prothorax, blackish, the clypeus bright rufous throughout, 

 nearly as in the preceding, except that the frontal punctures are 

 mingled with numerous smaller punctures; antennal club (cf) a 

 little longer than the preceding six joints; prothorax very evidently 

 less transverse, the sides feebly converging and broadly arcuate 

 from base to apex, the basal angles more broadly rounded; basal 

 bead entire; punctures everywhere strong and distinct, larger and 

 rather dense toward the sides; ground color uniform; median line 

 feebly impressed; scutellum with numerous punctures bearing long 

 hairs; elytra nearly as in the preceding but more elongate, with 

 smaller and sparser punctures and even more distinct pubescence 

 throughout; pygidium with similar long erect conspicuous yellowish 

 hairs; hind tarsi (cf ) nearly one-half longer than the tibiae; abdomen 

 as in the preceding but with still shorter sixth segment. Length 

 (cf ) 16.0 mm.; width 8.4 mm. Southern California, .magister n. sp. 



Elytra without any definite or constant trace of nubilate maculation, the 

 elytral setae sparser and still less obvious, easily removed 4 



4 Body very stout, oblong, convex, very variable in size, rather shining, 

 pale yellow-brown in color throughout, the head as in the preceding, 

 piceous-black, rather strongly, discretely punctate, with some minute 

 punctures intermingled; clypeus dark rufous, fully twice as wide as 

 long, the sides parallel basally, sinuato-oblique thence to the rounded 

 and strongly reflexed apex; punctures rather coarse and dense but 

 not very deep; median line frequently feebly impressed, the suture 

 sinuate medially, narrowly (cf), broadly (9); eyes not differing 

 much sexually, in the female separated by two and one-half times 

 their width; antennal club (cf) fully three-fourths as long as the 

 stem, not differing much in the female; prothorax three-fifths to
