shorter than tibiae, and the first joint nearly as long as the follow-

 with a more or less bronzy tinge, and the surface more coarsely 

 punctate and rugose, outer antennal joints about as long as wide, eyes 

 equally rounded above and beneath, usually more greenish above and 

 beneath, abdomen beneath more coarsely punctured, and the first 

 segment slightly flattened at middle, prosternum more densely punc- 

 tured, and densely clothed with long, erect, fine hairs, and the an- 

 terior and middle tibiae more or less arcuate, and armed with a short, 

 arcuate tooth on inner margin at apex. 



Kedescribed from the lectotype No. 3477 in the Academy of Natural 

 Sciences, Philadelphia. Doctor Horn had three females before him 

 when he described this species, and from his description considered 

 the specimen from near Los Angeles as the type, although not labeled 

 as such by him. The other two paratypes are from the Santa Cruz 

 Mountains, Calif., and are in the United States National Museum. 



Type locality. — Near Los Angeles, Calif.

Valuations. — Specimens examined vary in length from 4.75 to 6.75 

 millimeters, and in width from 1.25 to 2.25 millimeters. The females 

 are rather uniform in coloration, but in the males the pronotum 

 varies in color from dark bronzy green to a coppery red, and the 

 elytra from a bronzy brown to a bluish black, with a feeble greenish 

 reflection. In some examples the prosternal lobe is nearly truncate 

 in front, the anterior median depression on pronotum is variable in 

 size, and sometimes the basal half of the pronotum is deeply depressed 

 in front of the scutellum.
