Baracoa, Cuba, August, 1902 (A. Busck). 



Type.— Cat No. 20712, U.S.N.M. 



This is very probably a red variety of T. wilsoni, but it seems to 

 deserve a distinctive name. I have no specimens of wilsoni to com- 

 pare; possibly they would show structural differences. The light 

 orange-fulvous markings of the abdomen are very bright and beau- 

 tiful. 



NOMADA AZTECORUM PEATENSIS. new Bubspeciei. 



Female. — Length 10.5-11.5 mm. Differs from the typical form as 

 follows: Legs (except coxae) bright ferruginous, the hind femora 

 suffused with blackish behind ; yellow area of clypeus triangular ; lat- 

 eral face-marks more extended above, but variable; cheeks red or 

 with a red band behind eyes; mandibles ferruginous, blackish api- 

 cally; labrum ferruginous; mesothorax with two broad dull red 

 bands, or these absent ; spots on metathorax red ; yellow band on first 

 abdominal segment widely interrupted; venter with variably devel- 

 oped yellow bands, on fifth segment a yellow spot on each side. 



Allotype — Male. — Length, 10-12.5 mm. Similar to the female, 

 but with the following sexual characters: Face yellow, except a black 

 line bounding clypeus and supraclypeal mark; labrum and large 

 spot on mandibles yellow ; red band on cheeks narrow or nearly 

 obsolete; scape greatly swollen, punctured, black, red at base and 

 at apex on outer side; third antennal joint conspicuously longer than 

 fourtli; tegulae with a rather obscure yellow spot; femora marked 

 with black near base and with variable yellow stripes, which may 

 be obsolete; apical plate of abdomen entire or very faintly notched, 

 its surface often marked with yellow. 



Meadow Valley, Mexico, 2 females, 5 males, collected by C. H. T. 

 Townsend. 



Type.— Cat. No. 20713, U.S.N.M. 



This seems to be a subspecies rather than an individual variety; 

 the locality is far north of that (Amecameca) of typical N. aztecorum 

 Cockerell. 



NOMADA HEILIGBRODTI Creaaon. 



Both sexes from Cypress Mills, Texas, from the Ashmead collec- 

 tion. The male described by Cresson does not belong to this species ; 

 the true male has yellowish-white markings, face all light below 

 antennae, apical plate of abdomen notched. The abdomen of the 

 male looks just like that of N. scita Cresson, but the antennae are 

 entirely different. The metathorax is obscure reddish without spots. 

 The densely and coarsely punctured mesothorax distinguishes this 

 from the very similar N. vierecki Cockerell. 



COELIOXYS (LIOTHYRAPIS) FENESTRATA Smith. 



Soochow, China (N. Gist Gee) ; Hakone, Japan, August 15 (Sasaki 

 No. 154). Both are females; the Japanese one has the last ventral
