Ophion costale Cresson 1 



This rare species is represented by only one individual, the 

 type being in Mr Cresson's collection. It may be that this form 

 is but a sport, though at present we can do no better than to allow 

 it to stand as a distinct species. 



Description. Female. " Fulvo-ferruginous, shining, face broad, 

 the middle closely punctured, subtuberculate immediately be- 

 neath base of antennae; clypeus strongly punctured, tips trun- 

 cate, lateral sutures and tips of mandibles black ; cheeks swollen ; 

 antennae shorter than usual, reaching about to tip of second ab- 

 dominal segment; mesothorax convex, polished; scutellum very 

 convex; metathorax confluently punctured, without transverse 

 carina, sutures of thorax narrowly black; wings subhyaline, 

 stained with yellowish at base and with fuscous along apical 

 costal margin, darkest at tip of marginal cell; basal margin of 

 third and fourth abdominal and an oblique mark on sides of 

 second segment^ black." Length 13 mm. Habitat: Klamath 

 county, Cal. 



" Keadily distinguished from all other species known to me by 

 the ornamentation of the wings." [Cresson] 



Genophion n. gen. 



This genus is proposed to include certain forms remarkable for 

 the development of the lower portions of the head, resulting in a 

 very elongate face and considerable distance between the normal 

 sized eye and the base of the mandible. This is specially marked 

 in Genophion gilletti Felt, the generic type.

Genophion gilletti n. sp. 

 This small form resembles O. color adensis Felt, but may 

 be easily separated from it by its shorter antennae, longer face 

 and the dark fuscous coloration of the wings. It is described 

 from one female from Colorado, no. 2565, kindly sent me by Prof. 

 C. P. Gillette, in whose honor it is named. 



Description. Dark ferruginous, with the head and thoracic 

 sutures black and the wings tinged with dark fuscous. Wing 

 spread about 18 mm, length of- body 9 mm.
