Pediliis flabellatus Horn 

 Trans. Am. Ent. Soc. X, 1883, p. 306. 



Length 4.5-6.5 mm. (teste Horn), S-S.S mm. in the material 

 before me. 



Black, prothorax and legs reddish yellow, integuments strongly 

 shining. 



Antenna piceous, flabellate in the male. 



Head with a few fine punctures. Eyes distinctly more promi- 

 nent than the tempora, the latter slightly convergent. 



Prothorax widest before the middle, narrowed posteriorly, very 

 finely remotely punctate. 



Elytra finely, not closely, punctate. 



Male: Antennae with joints 2 and 3 short, 4-10 branched,, the 

 processes shorter on joints 4-5, but on 6-10 nearly as long as the 

 width of the head across the eyes; joint 1 1 as long as the five 

 preceding and equal in length to the process of joint 10. Elytra 

 unmodified at apex; tarsi not at all dilated and without squamules 

 beneath. 



Female: Antennas normally serrate, the second joint alone small. 



A very distinct and isolated species, unique in the structure of 

 the $ antennas and In the form of the prothorax. According to 

 Horn, one $ out of six examples seen has the elytra pale. 



The type series was from Western Nevada — doubtless from the 

 Eastern slope of the Sierras. 



There are before me nine specimens — 8 5 's, 1 2 — from the fol- 

 lowing localities, all in California: Lake Tahoe (Tallac and 

 Tahoe City, taken by Dr. Fenyes and myself respectively) ; Sugar 

 Pine, Yosemite region (Fenyes) ; Plumas Co. (Van Dyke Coll.) ; 

 Mohawk (Fenyes) ; Castle Crag (Fenyes) ; Sisson — June (my 

 Coll.) ; McCloud (Van Dyke).
