REPORT OF THE STATE ENTOMOLOGIST 1.903 119 



Distribution. This species is widely and probably generally dis- 

 tributed in the northern United States and southern Canada. It 

 was described from Massachusetts, has been met with in numbers 

 at both Albany and Ithaca N. Y. and was repeatedly reared by 

 Professor Davis in Michigan. In addition Ave have specimens be- 

 fore us from New York city [Joutel] ; Ottawa, May 19, 24 and 

 June 8, Toronto, August 21, Grimsby, June 6, Port Hope, May 5, 

 and Vancouver Island, May 3, all from Canada through .the kind- 

 ness of Mr W. H. Harrington.

Ophion bifoveolatum Brull^ 

 This species is one of the more common forms belonging to the 

 genus and if one may judge from trap lantern records, it is 

 largely diurnal and not crepuscular or nocturnal as in the case 

 of some of its close allies. This conclusion is further borne out 

 by the reduced size of the eyes, being decidedly smaller than in 

 related species and distant from the mandibles. This species 

 occurred in the trap lantern material taken at Ithaca in very 

 small numbers compared to those of the closely allied Ophion 

 bilineatum Say. It has a somewhat exceptional host in 

 white grubs, compared with other members of the g-enus and so 

 far as known to us has not been reared from any other species. 



Description. Fulvo-ferruginous with small eyes distant from 

 mouth; costal vein inclined to black; cubitodiseoidal nervure 

 rarel}^ appendiculate ; bulla of the second recurrent nervure 

 usually close to tip of cubitodiseoidal nervure and abdomen less 

 compressed than in its close allies. 



Head medium ; face frequently fulvous laterally, broad ; man- 

 dibles stout with black tips; clypeal fossae deep and usually 

 black; antennae dark brown, stout and not as long as the body; 

 ocelli black and ecpiidistant. Thorax sometimes dark brown, 

 finely punctured and with sutures more or less black; meso- 

 thorax convex; scutellum and postscutellum prominent, the 

 former sometimes a light ferruginous; dorsum of metathorax is 

 usually smooth. Wings hyaline; stigma well developed; costal
