Soldier. Head twice as long as broad ; and the antennae and man- 

 dibles scarcely as long as width of the head. 



The male is readily separated from T. flavipcs by its smaller size, paler 

 color, paler wings; and the soldier by its more elongate head; both 

 forms being more slender throughout than T. flaripcs. 



The new species I have taken from Falls Church and Chain 

 Bridge, Ya., and from Washington, D. C. The T. flavipcs, I 

 have from Falls Church, Va., Washington, D. C., Angelsea, 

 N. T., and Sea Cliff, N. Y. 



Two new species of Perdita (Hymenoptera). 



BY H. L. VIERECK. 

 Perdita bradleyi n. sp. 



cT. In size and structure very much the same as octomaculata, in color 

 more like monardae, in sculpture this differs from both of the preceding. 

 Dorsulum highly polished, with rather widely separated and somewhat 

 inconspicuous setigerous punctures. The scutellum and postscutellum 

 are shining with scattered setigerous punctures, the pleura are in struc- 

 ture very like the scutellum ; Metathorax shining, smooth and seemingly 

 impunctate ; abdomen shining, with widely separated setigerous punc- 

 tures ; dark portion of head dullish, the yellow portion polished, the en- 

 tire surface with sparse setigerous punctures. Color : head and thorax 

 mostly dark and metallic ; the dark portion of the head and metathorax 

 bluish the same portion of the rest of the thorax greenish ; dorsum of 

 abdomen mostly brown, seemingly black at base and near the apex ; the 

 lower half of the face and a little more also the front of the scape are 

 lemon-yellow, as are the tubercles and an interrupted band on the pro- 

 notum. Longitudinally half of the flagellum is orange yellow with a 

 brownish cast ; anterior and middle legs and venter of abdomen almost 

 exclusively lemon yellow ; the posterior legs are partly yellow and partly 

 brown as follows : Coxae with the greater portion of the upper half 

 brown, more than half of the outer side of the femora brown, and the 

 outer side of the tibiae entirely brown. There is a slender interrupted 

 band of yellow along the apical margin of the first dorsal abdominal seg- 

 ment and a similar band at base of the fifth, as well as the fourth, dorsal 

 abdominal segment. In addition there is a similar band at base and 

 apex of the second and third dorsal abdominal segments. The wings 

 are practically colorless, excepting for the nervures and the stigma, the 

 former being dark brown along the costa and pale brownish, rather 

 brownish testaceous elsewhere, the latter being translucent testaceous. 

 The left wing has three submarginal cells by virtue of the first transverse 

 cubitus forking near its base where it joins the cubitus. In the right 

 wing there are but the normal (for this genus) two submarginal cells.
