tour of body. Moreover, as they were taken together, the differences 

 in this case do not seem to be of specific value. Briefly, the points 

 of difference between the two individuals may be stated thus: 



a. Head brown ; ocelli large, the distance between the eye and 

 hind ones less than the diameter of an ocellus ; stigma fuscous, 

 marginal cell projecting beyond the stigma by nearly the width of 

 the latter. 



b. Head concolorous; ocelli small, the distance between the eye 

 and the hind ones considerably greater than the diameter of ocel- 

 lus ; stigma black, marginal cell projecting from it by less than 

 one half the width of the stigma. 



These specimens differ from the description ofincequalis as follows : 

 antennae not darker; marginal cell longer, second submarginal 

 longer than the third, third submarginal subquadrate, but higher 

 than long. 



The petiole of the abdomen is highest just behind the middle, and 

 then is flattened to the tip, which seems to be different from the 

 conformation in huequalis. Until the specimens are compared with 

 the types of Mr. Fox's species it would be unwise to found another 

 species on them. 



111. Brachycistis glabrella Cresson (12). 



Twenty-two specimens, variable in the length and shape of the 

 petiole of the abdomen. Alberquerque, Silver City, Arrogo, and 

 Organ Mountains, New Mexico, taken at light (Cockered) ; New 

 Mexico, Texas (M. C. Z.). 



112. * Bracliycistis castaueus Cresson (14). 



"Texas" (Chicago Acad. Sci.); Mesilla Park, La Cueva, Silver 

 City, Deming, Arrogo, New Mexico (Cockered). At light. Numer- 

 ous specimens. 



113. ' Brachycistis indiscretus Fox (16). 



Eight specimens, taken at light at Mesilla Park, May (Cockered ), 

 appear to belong here. The variability lies in the sculpture of the 

 mesonotum, which is generally very finely granular and with a 

 broad, shallow dorsal groove, and in the neuration of the wings. 

 The third submarginal is inconstant as to form, ranging from a 

 nearly closed circle to a subquadrate cell larger than the second 

 submaro;inal.
