CERATOMYIELLA AND PARADIDYMA — REINHAED 15 



Legs largely black, trochanters yellow, coxae less distinctly so; 

 fore tarsal segments normal, the claws and pulvilli short but dis- 

 tinct; mid tibia with a whorl of three bristles near middle, the one 

 on outer front side stout; hind tibia with only three strong bristles 

 on outer posterior edge. 



Wings with a brownish tinge on broad anterior margin, some- 

 what paler behind; venation bare except third vein, which is setu- 

 lose almost to small cross vein ; fourth vein with a broadly rounded 

 stumpless bend, concave beyond; hind cross vein perpendicular to 

 fourth, joining it midway between small cross vein and bend; api- 

 cal cell closed, petiole short, reaching costa shortly before the wing 

 tip; epaulets blackish; costal spine developed but not very strong. 



Female. — Front at vertex 0.296 of the head width (average of five : 

 0.3; 0.29; 0.29; 0.29; 0.29), widening uniformly to antennae; the 

 usual two proclinate orbitals present; verticals two pairs; antennae 

 a little shorter than face, third segment narrow but wider than para- 

 facial below, about five times longer than the second; arista thick- 

 ened on proximal fourth, pubescent to tip; cheek about one-fourth 

 the eye height; fore tarsi comjDressed, the segments slightly swollen, 

 claws and pulvilli minute. 



Length. — Male, 6 mm ; female, 5.5 to 7 mm. 



Type.—MalQ, U.S.N.M. no. 44758, from College Station, Tex. 



Remarks. — Described from eight specimens. In my collection, 1 

 male and 3 females, College Station, Tex., September 25 and October 

 11, 1930, August 24, 1931, and October 19, 1933 (H. J. Reinhard). 

 In the United States National Museum, 4 females as follows: 1, 

 Brownsville, Tex., June (C. H. T. Townsend) ; 1, Yuma, Ariz., June 

 26, 1917 (J. M. Aldrich) ; 2, Las Cruces, N.Mex., one labeled " Ckll. 

 2293, Aug. 1894 ", the other without collector's label. The specimen 

 collected by Cockerell also bears Coquillett's determination label, 

 Paradldyma siiigularis Townsend. 



The species is strictl}^ congeneric with the type species, conica^ 

 from which it differs in having black legs and broad, well-defined 

 thoracic stripes; in being more robust in build; and in other 

 characters.
