Ferruginous ; wings fuliginous to fuscous ; body especially frequently 

 marked with black ; nervulus a7itefurcal ; nervellus broken below the 

 middle. 



Length, 20-33 mm. ; wing, 15-22 mm. ; spread, 33-47 mm. ; antennae, 

 20-30 mm. 



Ferruginous, varied with black and fulvous ; head impunctate or 

 finely punctured, clothed with fine, short, white pubescence, longer on 

 the labrum ; vertex of the general color — in one specimen black — eyes 

 and ocelli black or dark brown ; eyes emarginate, medium to small, 

 distant from the base of the mandibles, clypeal fovese deep ; mandibles 

 bidentate, tipped with black. 



Thorax ferruginous to fulvo-ferruginous, shining, densely but finely 

 punctured and clothed with fine, short pubescence ; mesonotum with 

 parapsidae indistinct or lacking ; scutellum deeply excavated in front, 

 connected with the mesonotum by lateral carinae ; metathorax gradu- 

 ally sloping and slightly flattened behind, with median furrow and 

 shallow arcuate carinae originating about the insertion of the abdo- 

 men ; a lateral carina at the edge of the posterior area bordered with 

 a reticulate band ; spiracles large, linear, surrounded by a groove. 



Wings light to dark fuliginous, somewhat lighter towards the apex; 

 stigma flavous ; nervures fuscous, nervulus antef ureal to interstitial, 

 nervellus broken below the middle ; radial vein slightly sinuate, a 

 small glabrous area below its base in the discocubital cell ; discocubital 

 vein unevenly arcuate ; the outer half of the third discoidal cell en- 

 larged ; legs fulvo-ferruginous, claws pectinate ; abdomen of the gen- 

 eral color, often varied with black beyond the first segment ; in one 

 specimen almost entirely black beyond the second ; in another this 

 color occupies the ventral half of the fourth and succeeding, while in 

 the third the ventral half of the abdomen beyond the first segment is 

 of this color. 



In redescribing this species I have examined the type and 

 eight specimens. 



Type.— 9 . No. 2053, U. S. National Museum, Texas. 



A good species, easily separated from other members of 

 this genus by the more or less distinctly fuliginous wings.
