North American Rhynchopliora. 245 



distant, and indistinct punctures ; intervals alternately slightly more 

 strongly convex, each with a single row of fine, semi-erect, widely 

 distant setae. Abdomen more sparsely covered with scales which are 

 plumose, also with excessively short, sparse setae. Legs finely setose, 

 densely squamose ; tarsi densely pubescent above and much more 

 densely so beneath. Length 6.8 mm. 



California (Los Angeles Co. 1). 



Easily distinguished from the next by its larger size, more 

 robust, depressed form, and finer, longer dorsal setae. 



A. gracilior n. sp. — Form elongate-oval, convex, densely clothed 

 with pale, uniform, cinereous scales which are densely crowded, glazed 

 and graniform above, plumose beneath. Head small, moderately 

 convex ; beak sparsely squamose ; surface feebly granulose or finely 

 rugulosely punctate ; eyes prominent, very coarsely granulated, large. 

 Prothorax cylindrical, fully as long as wide, evenly and not strongly 

 rounded at the sides, constricted just behind the anterior margin, the 

 groove becoming very broad and shallow at the middle of the disk ; 

 base and apex truncate, the former slightly the wider ; disk convex^ 

 even, not punctate, densely granulato-squamose. Scutellum small but 

 distinct, ogival. Elytra elongate-oval, but slightly less than twice as 

 long as wide, acute at apex, more than one-half wider than the pro- 

 thorax ; sides broadly arcuate ; humeri broadly rounded ; disk convex, 

 finely striate, the striae with very fine distant punctures ; alternate 

 intervals more strongly convex, all with a single row of short, sub- 

 recumbent white setae which are rather distant. Abdomen with fine, 

 erect, sparse setae, much longer than those of the upper surface, densely 

 squamose. Legs setose, densely squamose ; tarsi setose above, densely- 

 pubescent beneath. Length 5.5 mm. 



California (Los Angeles Co. 2). 



The scales of the under surface are rather large and are 

 beautifully plumose around their entire circumference. 



This species is easily distinguished from the preceding, in 

 addition to the characters given above, by the longer setae of the 

 abdomen and the rather shorter second ventral segment, the 

 first suture being less strongly arcuate in the middle. 



PERITAXIA Horn. 



In this genus the ocular lobes are of less than usual impor- 

 tance, and in several other minor characters it is more or less 

 heterogeneous. 



P. perforata n. sp. — Form elongate-oval, convex, black through- 

 out, except the antennae which are piceous-black and rufous toward the
