Anihophora fedorioa n. sp.— 'J,. Length about 16 miu. ; black, the 

 head, thorax and first abdominal segment with pale hair, not mixed with black ; 

 this hair is strongly tinged with yellowish on the head above and mesothorax, 

 but otherwise is white or nearly so, being long and pure white on the cheeks; 

 eyes greenish-yellow ; facial quadrangle longer than broad ; mandibles all dark ; 

 face markings chrome-yellow, including the labrnm (except the narrow anterior 

 edge, and a large spot at each upper corner), clypeus (except narrow anterior 

 edge, and a large irregularly quadrangular mark at each upper corner), a naiTow 

 transverse supraciypeal band, and the lateral marks, which end narrowly on 

 orbital margin about the level of antennae ; scape yellow in front, tlagellum en- 

 tirely black ; tegulse ferruginous; wings clear, with a ferruginous stain in upper 

 part of first submarginal cell ; abdomen shining black, the hind margins of the 

 segments dark reddish; no hair bands; the second segment beyond the middle, 

 the third and fourth, and the base of the fifth and sixth have short erect black 

 hair; hair about apex white; apical plate broad ; legs (including the tarsi) black, 

 with mainly white hair; long hair of middle tarsi black and white mixed ; basal 

 joint of hind tarsi neither distorted nor spined or toothed. 



Hab. — Fedor, Texas, April 29. (Birkmami.) Looks something 

 like a pale example of A. montana, but is easily separated by the 

 dark markings of the clypeus and the much broader apical plate, 

 as well as the abundant black hair on the middle tarsus. From 

 A. crotchii it is known by its broader face, dark markings of cly- 

 peus, and absence of any broad black brush at end of middle tarsus. 

 The clypeal marking resembles that of ^4. simillwm, but that differs 

 greatly in the legs, etc.
