by the ferrugineous color. The anterior femora of the male are 

 thin, concave beneath and produced ventrally as in nodosa except 

 that they are widest in the apical third, where the width is about one- 

 half the length of the femur. The anterior tarsi are flattened and 

 resemble very closely those of nodosa. 



DIDINEIS SANCTACRUCAE Bradley 



Didineis sanctacrucae Bradley, Trans. Amer. Ent. Soc, vol. 46, No. 801, 1920, 

 p. 129. 



This species is unknown to us except through the description. 

 The types are in Cornell University. Bradley suggests that these 

 may be the female of nodosa, and it is very probable that this 

 association is correct. 



DIDINEIS TEXANA (Cresson) 



Alyson texana Ceessok, Trans. Amer. Ent. Soc, vol. 4, 1873, p. 226. 



The type of this species is in the United States National Museum. 

 It was originallj^ described from a single male from Texas. There 

 are specimens before us from Texas, Pennsylvania, District of 

 Columbia, St. Augustine, Fla. (April 20, 1919, C. W. Johnson), 

 Columbus, Ohio (July 15, 1921, A. E. Miller), St. Louis, Mo. (Eau 

 No. 2633), and Tifton, Ga.

 closure of propodeum elongate U-shaped, its basal width over half 

 its greatest length, the surface with a more or less complete central 

 carina and three or four diverging carina on each side of it which 

 are more or less connected by weaker rugae ; laterad of the enclosure 

 there are numerous fine rugae which are almost transverse, and the 

 posterior face is finely rugoso-reticulate ; mesopleura and sides of 

 propodeum finely rugoso-punctate. Basal sternite coarsely longi-
