CHARLES W. HOOKER. 27 



Thorax polished, sericeous, with deeply impressed, black sutures ; 

 the posterior suture of the metapleurae finely beaded ; scutellum rounded ; 

 metathorax smoothly rounded behind, without distinct carinas ; wings 

 subhyaline, fulvoferruginous, stained with yellowish at the base and 

 with fuscous along the costal and apical margins, deepest in the radial 

 and marginal cells stigma well developed, flavous ; discocubital vein 

 evenly bent, not appendiculate, nervulus slightly postfurcal, nervellus 

 broken well above the middle ; first recurrent vein not over half the 

 length of the second, basal vein slightly bent at its lower end, towards 

 the base of the wing ; legs ferruginous, except the anterior and median 

 trochanters and the articulation of the trochanters and coxae, which 

 are black ; claws pectinate. 



Abdomen strongly compressed, slightly darker colored and varied 

 with black. 



Redescribed from the type and one additional female spe- 

 cimen. 



Type. — 9. No. 63, American Entomological Society of 

 Philadelphia. 



This species is closely related to O. bifoveolahcs, and may 

 prove to be only a subspecies. Mr. E. T. Cresson described 

 this species from a single female, which has long stood as 

 unique, and consquently has been regarded as possibly a 

 sport. On examining the 9 type of Genophion gilletti Felt, 

 however, I found that it was synonymous, and the existence 

 of this second specimen shows that the characters are fairly 

 well fixed. Dr. Felt erected for this and another species a 

 new genus — Genophion — based on " the very elongated face," 

 but this occurs in other species and genera to an equal degree, 

 and can not, I believe, be given generic value. The apparent 

 length of face is largely due to the decrease in the size of 

 the eyes and is frequently seen in the specimens of O- biio- 

 veolatus. 



Distribution. — This rare species is recorded as having been 

 taken in Klamath County, Cal.,* and Colorado, but as it is 

 represented by only two specimens its range is not known. 



Nothing is known of the life history, habits or hosts. 



* There is no Klamath County, Cal., so this must refer to the town 

 of Klamath in the northwestern corner of California County, Oregon, 

 which lies on California's northern border.
