f 



Ophion ferruginipennis n. sp. 

 One example of this unique form was in the collection of the 

 United States National Museum and through the kind forbear- 

 ance of Dr Ashmead its characterization has fallen on the writer. 

 Another specimen was taken by Mr L. H. Joutel in the vicinity of 

 New York city. 



Description. Ferruginous ; wings ferruginous and with a spread 

 of about 40 mm ; metathorax strongly areolated in much the same 

 way as in O. t i t y r i Pack.

 fossae deep ; antennae nearly as long as the body. The fossae at 

 their bases are well marked. Eyes large, extending nearly to the 

 mandibles; ocelli black and the posterior pair almost contiguous 

 to the eyes ; thorax sericeous ; mesothorax convex ; scutellum and 

 postscutellum prominent. Metathorax with two well developed 

 transverse carinae and a number of longitudinal ones radiating 

 from the insertion of the first abdominal segment. Wings sub- 

 hyaline with a distinct ferruginous and, in places, fuscous tinge, 

 specially at their base and along the anterior margins. Cubito- 

 discoidal vein with its appended vein stub extending one third 

 across the cell from the well marked angle; bulla of second re- 

 current nervure a little distance from the cubitodiscoidal vein 

 [pi .2, fig.l]. Legs light ferruginous, concolorons ; claws pectinate; 

 abdomen strongly compressed and somewhat darker at the tip.
