THE FAMILY EUCHARIDAE — GAHAN 455 



in the San Francisco earthquake and fire. Five specimens in the U. S. 

 National Museum, collected in Pinery Canyon, Chiricahua Mountains, 

 Cochise County, Ariz., July 26, 1919, by Dr. Witmer Stone, seem to 

 agree perfectly with Ashmead's brief description of viridis and are 

 taken to be representatives of that species. 



The same collection contains two small series of specimens identified 

 by A shmead as ymW«5 that appear to agree with the above-mentioned 

 specimens except that they have a longer and more slender stigmal vein 

 and the scape of the female is usually yellowish instead of metallic. 

 These characters are the only ones by which I am able to separate what 

 I believe to be mridis from wheeleri Wheeler, and consequently I have 

 transferred both series of specimens to the latter species (see remarks 

 on loheeleH). 



Orasema viridis^ as represented by the five specimens already men- 

 tioned, is very similar to neomexicaTia^ new species, but is readily dis- 

 tinguished from that species by the metallic-colored femora and scape. 

 It differs from cockerelU^ new species, by having the petiole of the 

 female more slender and obviously longer than broad, by having the 

 scape metallic, and by its distinct green color. From occidentalis Ash- 

 mead it can be distinguished by the strongly sculptured second sternite, 

 the shorter stigmal vein, and its brighter green color. 



The head, thorax, propodeum, and abdominal petiole are nearly 

 uniformly alveolately punctate with only the clypeus, metapleura, 

 and upper half of mesepimeron somewhat more weakly sculptured. 

 The hindcoxae are sculptured above, smooth beneath. The clypeal 

 margin is very nearly straight and the separation between clypeus 

 and supraclypeal area is indistinct, being merely a broad shallow 

 depression. The scutellum is without a median depression but the 

 transverse groove is distinct as are also the lateral grooves. The 

 wings are hyaline with the stigmal vein about one and one-half times 

 as long as thick and not especially slender, the postmarginal vein 

 weak but distinctly longer than the stigmal and the costal cell is 

 sparsely hairy. The antennal flagellum is a little thicker than the 

 pedicel, its first funicle joint about twice as long as the pedicel and 

 about one and one-half times as long as broad, the following funicle 

 joints subquadrate. 



The male is like the female except that the antennae are very 

 slightly longer, the abdominal petiole is about one and one-third 

 times the length of hind coxa and the gaster is smaller. 



Besides the 5 specimens from Cochise County, Ariz., there is 1 

 female in the U. S. National Museum collected in the Huachuca 

 Mountains, Ariz., a gift of the Brooklyn Museum and bearing their 

 catalog number 320.
