70. Polycaon megalops, sp. nov. 



Allied to P. confertus, with which alone it can be compared because of 

 its ten- jointed antennae. It differs most conspicuously in the very large 

 and prominent eyes, which are separated by three times their own diam- 

 eter when viewed from the front, while in P. confertus they are distant 

 fully six times their own diameter. Further differences are arf follows: 

 prothorax distinctly wider than long, not canaliculate, the transverse 

 impression less distinct, the granulation less dense; elytra two and one- 

 half times as long as the head and prothorax (scarcely more than twice as 

 long in P. confertus), rather sparsely punctate, much as in the male of 

 P. confertus, but not at all granulate towards the sides and apex; second 

 and third tarsal joints with only a group of projecting hairs, instead of 

 the densely matted brushes which in P. confertus assume the appearance 

 of membranous lobes. 



Two examples have been seen, both apparently 

 females; one, in the writer's collection, is 5 mm. in 

 length, the other, in the collection of Dr. Van Dyke, is 

 7 mm. long. The larger specimen barely reaches the 

 stature of the smallest P. confertus, which varies in 

 length from 7.5 to 10.5 mm. 



Specimens taken at Pomona, Los Angeles County. 



71. Aphodius ungulatus, sp. nov. 



Oblong, scarcely broader posteriorly, antennae testaceous, club not 

 darker; head piceous, margin paler; sides fimbriate posteriorly; surface 

 not distinctly tuberculate, punctures moderate, a little finer and sparser 

 at the middle; clypeus emargiuate and distinctly though not sharply 

 angulate at sides. Thorax piceous with paler side margins, about one-half 

 wider than long, sides parallel, slightly arcuately narrowed in front, mar- 

 gins finely and rather sparsely fimbriate with short hairs; hind angles 

 obtuse; disk finely, rather sparsely punctate at middle, more closely and 

 coarsely at sides, with larger punctures intermixed; marginal basal line 

 distinct at sides but tending to become obsolete at middle. Elytra dull 

 yellow, immaculate, but with a lateral, not very sharply defined, fuscous 

 shade reaching from the humerus to beyond the middle; striae fine, with 

 fine punctures which are well separated, interspaces nearly flat, with two 

 more or less regular series of punctures which are about equal to those of 

 the striae. Beneath brownish, abdomen paler; surface alutaceous, abdo- 

 men and sterna, except at sides, sparsely punctate. Mesosternum not
