tures, intervals with a single series of submuricate punctures, colored with 

 reddish yellow in the followinsj manner: a small spot at middle of base, some- 

 times wanting, two spots at basal third, a fascia at middle, three spots near 

 the apex sometimes confluent. Body beneath black with feeble bluish lustre. 

 Prosternum and side pieces coarsely punctured, anterior margin strongly tri- 

 sinuate with a strong tooth on each side of the middle etnargination. Abdomen 

 at middle sparsely punctured, at sides densely and finely punctured and clothed 

 with long whitish recumbent hair. Last ventral with tlie apical margin dis- 

 tinctly double. Length .34 — ^.42 inch ; 8.5 — 10.5 mm. 



Several specimens from Owen's Valley, California. The ventral 

 character of this species rarely distinguishes it in the present group. 

 This species begins a small series in which the thorax is not margined 

 with yellow.

Two specimens before me from the Mariposa region of California. 



J)r. Leconte's specimen was obtained Irom the cabinet of Count 

 Mnizech of Paris with the above manuscript nanie. I do not know 

 that it has ever been published. My specimen is due to the late 

 Jules Thevenet of Paris and was collected by his brother in 3Jari- 

 posa County, California.

 near the tip which are reddish at the margin. Head coarsely punctured, front 

 slightly impressed, vertex with feeble carina. Thorax unicolored, twice as 

 wide as long, apex feebly emarginate, base truncate, sides moderately arcuate 

 in front, nearly straight posteriorly, margin narrow, scarcely visible from above
