OF WASHINGTON. 355 



and classification, and have here merely brought together a few of 

 my notes relating to the species found in our fauna. 



ORASEMA Cameron. 



In this genus two specimens have been described, as follows : 



1. O. violacea Ashm. Ent. Am., Vol. Ill (1888), p. 187. 

 Hab. Fla. 



2. O. minuta Ashm., 1. c. p. 188. 

 Hab Fla. 



To these I now add a third species from California. 



3. O. occidentalis sp. n. 



9. Length, 2.5 mm. Dull bronzy green, closely, finely punctate, the 

 head of a brighter metallic green ; scape, trochanters, tips of femora, tibiae 

 and tarsi, pale brownish-yellow; flagellum black, the joints after the first 

 quadrate; mandibles brownish. Thorax not very gibbous; the collar is 

 not visible from above; the mesonotum trilobed," the furrows punctate, 

 the lobes convex ; scutellum rounded, elevated posteriorly and with a trans 

 verse furrow before the tip, while the metathorax slopes obliquely off pos 

 teriorly with lateral sulci. Wings hyaline with brownish nervures ; the 

 marginal nervure is long, two-thirds the length of the subcostal, the stig- 

 mal minute, the postmarginal developed. Abdomen seneous, the petiole 

 short, stout, finely rugose, one and a half times as long as thick, or as long 

 as the hind coxae, and metallic green ; body of abdomen subtriangular, sul- 

 cate above at base. 



Hab. Los Angeles, Cal. 



Type in National Museum. 



Described from a single specimen collected by A. Koebele. 



CHALCURA Kirby. 



(i) C. gibbosa Prov. 



Eucharis gibbosa Prov., Pet. Faune Ent du Can. II, p. 591. 



Hab. Canada and United States. 



This species was described by Provancher, from a fjemale 

 specimen taken in Canada, but the discovery of the male shows 

 that it does not properly belong to the genus Eucharis as now 

 restricted, and that it must be relegated to Chalcura, the antennae 

 in this sex being ramose. 



Although rare, the species extends from Canada to Texas. 



In the National Museum there is a second species closely allied, 

 but evidently distinct, that may be described as follows :
