Kedescribed from the male lectotype, No. 3433, in the Academy of 

 Natural Sciences of Philadelphia. 



Female. — Differing from the male in having the front of the head more 

 sparsely pubescent, the prosternum more sparsely punctured and not quite so 

 densely pubescent, the last visible sternite more elongate and shallowly, broadly, 

 arcuately emarginate at apex, the middle tibia straight, and the anterior tibia 

 unarmed at apex. 



Type locality. — Nevada, no definite locality.

Chamberlin (1926) records viridicyanea from other localities in 

 California and Oregon, and Horn (1886) records it from Montana, 

 but no specimens from Montana have been examined by the writer, 

 and this locality record should be verified. 



Hosts. — Chamberlin (1917) records this species as breeding in the 

 limbs and smaller branches of incense cedar (Lioocedrus d-ecurrens 

 Torrey) in California, and (1925) records it in western juniper 

 (Junipenis occidentalis Hooker) in Oregon. The adults have been 

 collected on Douglas fir (Pseiiaotsuga taxifolia (La Marck) Brit- 

 ton), Jeffrey pine (Pinus jeffreyi "Oreg. Com."), and Port Orford 

 cedar (Chamaecyparis lawsoniana (A. Murray) Parlatore). 



The sculpture on the dorsal surface of the body is slightly variable, 

 and the color varies from bright green to violaceous blue. In some of 

 the specimens there are two more or less distinct, smooth callosities 

 on the front of the head, and the emargination at the apex of the last 

 visible abdominal sternite of the female is slightly variable in width. 

 In a few specimens there is a very narrow median lobe on the pros- 

 ternum. The length is from 7.5 to 11 mm. 



(37) Chkysobotheis xeoptisiela, new species 



(Fig. 37) 



This species is closely allied to pusilla Castelnau and Gory but it 

 differs from that species as follows : 



Male. — -Head, and antenna in part, bright green, and the genitalia more 

 strongly expanded at the middle, more uniformly brown in color, with the 

 median lobe broadly rounded at the apex, and the transparent parts of the 

 lateral lobes much shorter than in pusilla. 



Female. — Last visible abdominal sternite rather deeply, arcuately emargin- 

 ate at the apex, whereas in pusilla it is rounded or shallowly emarginate at the 

 apex. 



Length 6.5-8.5 mm., width 3-4 mm.
