Chrysops fulvistigmn, n. sp —Female. Palpi yellowish, antennae 

 slender, first segment yellowish, slightly darker at apex, second and third 

 segments brown, annulate ])ortion nearly black. Face shining black, 

 covered next the eyes and on the anterior parts of the cheeks with 

 yellowish-gray pollen. Front yellowish-gray pollinose, callosity and region 

 surrounding the ocelli shining black. Thorax dark, nearly black, with 

 grayish pollen above, giving the impression of stripes before the suture ; 

 coxa, basal two-thirds of femur and base of tibia of anterior leg, and nearly 

 the whole tibia and base of tarsus of middle leg, yellow ; remainder of legs 

 daik, nearly black. Wing almost hyaline, costal margin from base to 

 apex, and a narrow cross-band abbreviated behind pale brownish, stigma 

 conspicuously brownish-yellow. Abdomen yellow at base, black at apex. 

 Dorsally, a large, nearly square, black spot beneath the scutellum reach- 

 ing the posterior margin of the first segment. Second segment with two 

 contiguous, black triangles, their bases on the posterior margin of the 

 segment and their apexes not attaining the anterior margin ; otherwise the 

 first two segments are yellow ; remainder of the abdomen black, witii the 

 exception of a small, pale yellowish triangle on the third segment. 

 Ventrally the first two segments are yellow, with the exception of a linear, 

 black spot on each lateral margin, and a suggestion of the same colour at 

 middle. The yellow also extends back on to the third segment on each 

 side of the midventral line. 



Length slightly more than 7 millimeters. Two females taken at 

 Raleigh, N. C, by C. S. Brimley, July 15 and 17. 



A very distinct and interesting species. It has somewhat the aspect 

 of lugeiis, Wied., utiivittatus, Macq, and obsoletus, Wied., but the nearly 

 hyaline wings and black face are characteristic. As a pale brownish 

 colouring follows the costa to the apex of the wing, the species may be said 

 to belong to the group with an apical spot, and is the second North 

 American species of the group with an entirely black face, but this one 

 lacks the yellow pollinose stripe from base of antennae to margin of mouth, 

 a character very evident m/rigidus, O. S. 



The species is larger than iiigribiinbo, Whitney, and not to be con- 

 fused with it except in coloration of wings. 



Chrysops Brimley i, n. sp. — Female. Palpi and proboscis black, 

 antenna? about normal in length and thickness, first segment yellow,
