tinguish it. The nonvittate examples which, notwithstanding Horn's 

 remark, seem to be about as often 5 's as 2 's, somewhat resemble 

 pale specimens of picipcnuis, but the latter has a sparsely punctured 

 head and the male genitalia very different. 



All specimens before me with one or two exceptions are from 

 the vicinity of San Francisco. Most of them were taken by Drs. 

 Blaisdell and Van Dyke and bear labels Muir Woods or Redwood 

 Caiion, Marin Co., April 23-May 17. One example is from Ala- 

 meda Co., another in Dr. Fenyes' collection is from Point Reyes, 

 Marin Co.; one in Dr. Van Dyke's collection is from Santa Cruz 

 Co., and one from Mr. Hopping was taken at San Joaquin Mill, 

 Tulare Co., April 4. 



Pediliis Uneatiis n. sp. 



Length 5.6-8 mm. Closely similar to vittatiis, but more coarsely 

 punctate throughout. The head is quite as densely punctate as in 

 vittatus, the tempora as a rule a little more noticeably convergent. 

 The prothorax is rufous with a discal darker cloud which is vari- 

 able in extent; the punctuation though coarser, is rather sparser 

 than in vittatus, and there is in every specimen I have seen a very 

 fine median sharply impressed line which attains neither base nor 

 apex and may be quite short. This impressed line is indicated in 

 only one of the twenty-eight examples of vittatus before me. The 

 elytra are typically vittate in all examples. The sexual characters 

 are apparently the same as in vittatus. 



Described from 1 $ (type) and 5 2 's, all but one of which were 

 taken at Pasadena, Cal., in April and May, by Dr. Fenyes. The 

 remaining specimen bears simply the label "So. Cal." (Van Dyke 

 coll.).
