jcephalic or caudal margins of the wings. There are at least two cilia arising 

 from the apex of the marginal vein and one from the apex of the submar- 

 ^inal. Posterior wings with no discal ciliation centrally but a line or two of 

 minute cilia follow the margins on each side. 



Funicle of the antennae thicker after (distad) the third joint, the club 

 the longest joint ; joint 6 of the funicle is distinctly longer than the pedicel 

 ■and funicle joint 4 longer than joint 5 and subequal to joint i of the funicle. 

 the joints 4, 5 and 6 of the funicle each shortening. Club and joints 4, 5 

 and 6 of the funicle more hairy, subhispid, the white setae close, short and 

 •dense on the club. 



Mandibles 3-dentate, symmetrical, the dentations subequal but somewhat 

 variable, the middle tooth slightly the largest, all subobtusely conical. 

 ' From 16 specimens, g-inch objective, i-inch optic, Bausch and Lomb. 



Male. — Length, somewhat shorter in general than the female. 



Same in general habitus as the female but with longer, filiform, slender 

 antennae and shorter, less pointed abdomen. Characteristics the same. 



Antennae 13-jointed, pubescent with short white hairs, most noticeable 

 distad of the first funicle joint, the scape, pedicel and first funicle joint honey 

 yellow, the remaining joints brownish black, becoming gradually darker distad. 

 Scape short, dilated or convex ventrad, compressed, much longer and wider 

 than the pedicel but not as long by about a third as the proximal funicle 

 joint; pedicel smallest, obconic, about a third of the length of the proximal 

 funicle joint and slightly thicker ; remaining joints filiform and all subequal, 

 excepting the conic-ovate club joint and the proximal funicle joint; funicle 

 joints 2 to 5 about equal, longest, joint i a fourth shorter; joints 6 to 10 of 

 the funicle about equal, slightly shorter than joints 2 to 5, slightly longer than 

 joint I ; club joint slightly shorter, subequal to joint i of the funicle. Funicle 

 Vith the usual longitudinal carinae. 



Abdomen (lateral aspect) fusiform, obtusely convex dorsad, ridged 

 slightly along the meson ventrad ; (dorsal aspect) ovate, the second and third 

 segments united covering three-fourths of the surface, each subequal to the 

 other, the fourth segment a fourth the length of the third, the fifth shorter, 

 the sixth apparently minute, barely visible, the seventh and eighth apparently 

 equal or subequal, each slightly shorter than segment 5, the eighth short, 

 conic, with a loose tuft of hairs. Petiole (segment i) smooth, at least three- 

 fourths the length of the main body of the abdomen or nearly equal in length 

 to the united lengths of segments 2 and 3. 



From 7 specimens, 5 inch objective, i-inch optic, Bausch and Lomb. 



In addition to the specimens already named in this connection, I 

 liave received for determination from Mr. W. D. Pierce of the 

 National Bureau of Entomology a set of one male and three females 

 all mounted on tags and each bearing the following label : " Clarendon,
