34 CYRTIDAE OF NORTH AMERICA 



I have two large specimens from San Bernardino, California, 

 which are dull metallic blue with whitish pile and light brown 

 antennae (Coll. Van Dyke, in the U. S. N. M.). The tarsi are 

 darkened, the ocellar tubercle low. The coxae and the pleura 

 just above are purple. These specimens are apparently males. 

 Another specimen of the same size and from the same locality is 

 green in color with darker yellowish legs. The body has a slight 

 purple tinge and golden yellow pile. The antennae are pale 

 brown, the third joint very slender and pointed. Length, 12 mm., 

 wing, 11 mm. One of the males was figured in Dr. L. O. Howard's 

 Insect Book. A specimen from Los Angeles, California, has 

 golden yellow pile and a veiy long proboscis, with a low ocellar 

 tubercle. One specimen from Claremont, California, is dark 

 bluish green with lilack antennae and a low ocellar tubercle. 



One specimen from the Giant Forest, California, collected July 

 21, 1907, at 7,000 feet elevation by Prof. J. C. Bradley, is in the 

 Cornell University collection. This specimen is large and has a 

 very long proboscis. Some specimens from Lake County, Califor- 

 nia, have a rather low ocellar tubercle, and are blue green in color 

 with reddish yellow pile on the thorax. The venter is blue green 

 with narrow yellow margins to segments two, three (ind four. In 

 a specimen from Los Angeles County, California, the pile on the 

 occiput, eyes, and squamae is golden and long. The vein between 

 the discal cell and the outer fi^rst basal does not reach the wing 

 margin. In examining a large series of this species it will be found 

 that (as in tristis) the second submarginal cell varies from long 

 petiolate to subsessile. It is the only species with a curved 

 proboscis.
