sides of the face. Length of body 24 to 25 mm. ; to tip of the elytra 35 to 



37 mm. 



Described from one male and two feinales taken by Dr. F. E. 

 Blaisdell at Shasta Retreat, Siskiyou Co., Calif., at an altitude of 

 2,416 feet on July 11, 1905, one female taken by Dr. E. C. Van Dyke 

 at Nash Mine, Trinity Co., Calif., at an altitude of 8,000 feet, June 

 28, 19 1 3, and one female taken in April at Eldridge, Sonoma Co., re- 

 ceived from Mr. Davis. The elongated form, somber black color and 

 fulvous venter will distinguish this form.

Closely allied to rimosa and vanduzcei but larger than either. It 

 has the dull pubescent surface found in vandnzeei and the long male 

 valve of rimosa. It can be best distinguished from either by its having 

 the male uncus oblong and scarcely narrowed to the truncated apex. 

 The only specimen I have seen was a male type kindly sent me for 

 examination by Mr. W. T. Davis. It was taken in Mariposa Co. 

 in June.

This is a deep black, almost a bluish-black, species marked with 

 bright or reddish-orange. In this species the hind margin of the 

 pronotum and usually the lateral and anterior margins more narrowly, 

 are bright fulvous, and there may be a pale line on the middle of the 

 pronotum anteriorly extending a little on to the base of the vertex; 

 the supra-antennal plates are broadly fulvous and the usual six pale 

 marks on the mesonotum are well developed and I have considered 

 them typical in this species (two on the crown of the X, two at the 

 points of its anterior branches and two before these on the apex of 

 the loops). Here the ventral segments are vittate with black, the 

 head is 3^ by 7 mm., measuring on the slope of the head and across 

 the eyes; the pronotum is 35^ by 9 mm.; the width of the mesonotum 

 is 8 mm. ; and the elytra measure 8 by 28 mm. Uncus of male with- 

 out an apical hook. Length of the body 23 to 24 mm. ; to the tip of 

 the elytra 33 to 35 mm. This species occurs across the whole 

 continent from Vancouver Island to Quebec and as far south on the 

 west coast as Fresno Co., Calif.
