INVESTIGATIONS ON THE MUTILLID WASPS 177 



female, Lee County, August 7; female, Lee County, September 12, 1905; 



female, Lee County, September 13, 1905 ; female, Fedor, September 16, 1905 ; 



2 females, Fedor. 

 Electra differs not only in color and markings from quadriguttata 

 but is also much more coarsely sculptured throughout than the latter 

 species. It should be considered as a distinct species. 



61. DASYMUTILLA WILEYAE, new species 



Female.— R^didi and thorax black, abdomen red dorsally. Length, 

 11 mm. Head black with a slight reddish tinge, sparsely clothed with 

 erect and recumbent black hairs ; mandibles acute at the apex, a small 

 tooth within ; clypeus concealed by long, black hairs ; scape sparsely 

 clothed with coarse hairs ; first segment of flagellum equal in length 

 to segments two and three united ; antennal scrobes not carinate above ; 

 front and vertex rugoso-reticulate ; genae very closely and moderately 

 punctate; postero-lateral angles of head with a rectangular shiny 

 tubercle (similar in character and position to those found in inter- 

 Tupta and quadriguttata) ; relative widths of head and thorax 5-5.5. 



Thorax black, much longer than broad, sparsely clothed with erect 

 and recumbent black hairs; dorsum of the thorax rugoso-reticulate; 

 propleura coarsely and very closely punctate; mesopleura sparsely, 

 microscopically punctate on the anterior third, coarsely and closely 

 punctate on the posterior two-thirds ; metapleura shining with a few, 

 large, scattered punctures ventrally; sides of propodeum shining, 

 with large, scattered punctures on the anterior one-half, very closely 

 and coarsely punctured on the posterior half; posterior face of 

 propodeum at right angles to the dorsum, coarsely rugoso-reticulate. 



Abdomen black; first tergite coarsely punctated, especially toward 

 the apex, sparsely clothed with long, black hairs; integument of 

 second tergite black on the basal two-fifths, red on the median two- 

 fifths, and bladi on the apical fifth; second tergite with very deep, 

 coarse, and confluent punctures, the latter more separated at the 

 lateral margins; basal and lateral margins of second tergite with 

 scattered black hairs; remainder of tergite with thin, brilliant red 

 pubescence; tergites 3-5 closely punctured and with thin, brilliant 

 red pubescence; pygidium longitudinally striated; second sternite 

 with large, rather close punctures and scattered, long, pale hairs, de- 

 pressed and confluently punctate at the apical margin; sternites 3-5 

 confluently punctate ; sternites two and three with a thin apical fringe 

 of brilliant red hairs, the fringes on sternites 4 and 5 obscure and 

 dark, but with a tinge of red. 



Legs black; the femora sparsely clothed with black hairs above, 

 pale hairs below ; tibiae with black hairs.
