Two pairs of presutural and four pairs of postsutural macro- 

 chaetae on mesonotum ; acrostichals indistinguishahle from the rather 

 long discal hairs. 



Fore femur with a short, sharp, forwardly directed tooth at about 

 apical fourth on the postero-ventral surface, on the base of which, 

 on the posterior side, are 2 bristles ; antero-ventral surface with an 

 elongate, ridge-like callosity slightly nearer to base of femur; bristles 

 at base on postero-ventral surface very long, decreasing in length to 

 middle; beyond the postero-ventral thorn there are 2-3 short bristles 

 on same surface; fore tibia attenuated at base, hollowed out on ventral 

 surface, the postero-ventral margin with a slightly raised ridge on 

 middle; one long bristle on apical third of postero-ventral surface, 

 one, shorter, on dorsal surface nearer to apex and another short one 

 at apex on almost the posterior surface: fore metatarsus as long as 

 next 3 joints. Mid femur thin, slightly curved, and except at near base 

 almost bare ; mid tibia without any bristles. Hind femur elongated, 

 reaching slightly beyond apex of abdomen, curved, and slightly dilated 

 on beyond middle ; ventral surface with two short, closely approxi- 

 mated thick thorns, which have the tips dilated ; anterior surface with 

 a row of bristles which become longer and stronger, are more widely 

 placed and descend slightly as they approach apex of femur ; postero- 

 ventral surface bare ; hind tibia curved, apically becoming slightly 

 thicker, and four-fifths as long as femur; ventral surfaces on apical 

 half with numerous closely placed hair-like bristles which are at middle 

 rather more than equal in length to the tibial diameter, and rapidly 

 decrease in length to apex; dorsal bristle very long; antero-dorsal 

 surface with a series of short bristles from base to upper antero- 

 dorsal bristle. 



Wings with veins 3 and 4 slightly convergent ; last section of fourth 

 vein 2^2 times as long as penultimate section. Calyptrae with the 

 lower scale distinctly protruding. Length 4.5 mm. 



Holotype: Cloudcroft, New Mexico, May 24, 1902, (H. 

 L. Viersck). Type No. 6053. 



Allied to ciliata, Fabricius, but the absence of the very long 

 mid femoral apical bristles, so conspicuous in that species, 

 readily distinguishes it frotn ciliata. 



Pseudostenophora bispinosa n. sp. 



Female. — Black, subopaque. Antennae, tibiae and tarsi brownish- 

 yellow. Wings slightly grayish. Halteres yellow, knob black-brown. 



Frons twice as broad as long; second row of bristles straight, ot)e 

 pair of bristles only in first row; antennae normal in size; arista 

 nearly twice as long as width of frons, distinctly pubescent; palpi
