North American Rhynckophora. 251 



middle. Legs very sparsely squaraose, more densely setose, long ; tibiae 

 long and slender, the anterior strongly denticulate along the inner edge. 

 Length 8.5 mm. 



California (Anderson Valley, Mendocino Co. 1). 



In the type, which is probably a male, the anterior tibiae are 

 strongly bent inward near the apex. The middle tibiae are 

 slightly shorter than either the anterior or posterior, and both 

 the middle and posterior have a few small denticles along the 

 inner edge. The posterior tibiae are nearly straight, and not 

 abruptly, but at apex, as is related of the male of Dyslobus by 

 Dr. Horn (Proc. Am. Phil. Soc, XV., p. 41). This species in 

 fact appears to unite the characters of Dyslobus and Amnesia, 

 and perhaps indicates the propriety of uniting them under the 

 name Dyslobus. 



The present specimen was found in the sandy bed of the 

 Navarro River, under dried leaves, in the latter part of June. It 

 is probably one of the species peculiar to the great redwood 

 belt.

\. vestitus n. sp. — Form rather elongate-oval, convex; very densely 

 clothed throughout the body, legs and antennal scape with rather large, 

 widely overlapping scales, which are dark-brown in color, and very 

 deeply and coarsely striate. Head very short and broad, deeply in- 

 serted; beak three times as long as the head, more than twice as long 

 as wide; sides parallel, straight; alse rather large and dilated; surface 

 nearly flat, extremely, broadly, and feebly impressed transversely at 

 base, having in the middle near the apex a minute, elongate fovea, sparse- 

 ly, finely punctate, with prominent setiform erect scales, tip with a 

 small angular glabrous area; scrobes beginning at the apex, deep and 

 cavernous, feebly arcuate, rapidly becoming evanescent before the eyes, 

 and at a distance from them more than equal to their own width; an- 

 tennae rather robust; scape gradually enlarged from base to apex, pass- 

 ing just beyond the anterior margin of the eye, distinctly shorter than 

 the funicle; the latter not squamose, but with robust setae, fine pubes- 

 cence and a roughly pitted surface, two basal joints elongate, subequal, 

 remainder short, seventh slightly wider than long; eyes rather large and 

 finely granulate, feebly convex, wider than long, slightly pointed be- 

 neath. Prothorax scarcely as long as the head and beak, slightly wider 

 than long, widest slightly before the middle; sides distinctly and broadly 

 arcuate, constricted at the sides just behind the apex; ocular lobes 

 moderate in size, very strong, with a row of very short fimbriae, almost 

 entirely beneath the eyes, the latter free; base broadly arcuate; apex 

 truncate between the ocular lobes, distinctlv narrower than the base;
