INVESTIGATIONS ON THE MUTILLID WASPS 287 



Superficially this species resembles intermixta, but is smaller, has 

 the abdomen entirely pale ferruginous except the first segment, while 

 in intermixta the apical segments of the abdomen are black. The 

 genitalia of the two species also indicate that they are not closely 

 related. I have used the manuscript name suggested by Dr. J. C. 

 Bradley, who first recognized this species as new. 



130. DASYMUTILLA REPERTICIA, new species 



Plate 4, fig. 34 



Male.— BUck; vertex, pronotum, mesonotum, scutellum, apical 

 third of second abdominal tergite, tergites 3-7, sternites 3-6 laterally, 

 all with yellow pubescence, the remainder of the body with black 

 pubescence; second sternite with a very large, deep, median pit, 

 densely filled with hairs; length, 10 mm. 



Head black; front and vertex with scattered, long, erect, yellow 

 pubescence, the remainder of the head with sparse, long, erect, black 

 pubescence; mandibles acute at the tip, bidentate within subapically; 

 anterior margin of clypeus not noticeably bidentate medially; 

 clypeus densely, confluently punctate; scape bicarinate beneath, 

 densely punctured and clothed with coarse, erect, black hairs; first 

 segment of flagellum slightly shorter than the second (measured 

 dorsally); antennal scrobes strongly carinate above; front coarsely, 

 confluently p'unctate; vertex with shallow, indistinct punctures; 

 genae with sparse, small punctures, not nearly as coarsely sculp- 

 Uired as the front; posterior margin of vertex excavated laterally; 

 relative widths of head and thorax, 7-9. 



Thorax black; pronotum, mesonotum and scutellum clothed with 

 long, semi-appressed, yellow pubescence, the remainder of the thorax 

 clothed with sparse, long, erect, black pubescence; cephalic face 

 of pronotum punctate at the sides, glabrous, impunctate and dis- 

 tinctly emarginate medially, not rounded evenly into the dorsum; 

 pronotum, mesonotum, and scutellum very coarsely, confluently, 

 almost foveately punctate; narrow basal and lateral margins of 

 tegulae setigerously punctate, the hairs yellow; the tegulae for the 

 most part glabrous, impunctate; propleura with large punctures 

 at the margins, finely p'unctate medially, mesopleura with large, 

 scattered punctures anteriorly, posteriorly with the punctures foveate, 

 contiguous, somewhat confluent; metapleura, glabrous, impunctate, 

 except for scattered large punctures ventrally; sides of propodeum 

 glabrous, not sculptured anteriorly, foveately reticulate posteriorly; 

 posterior face and dors'um of propodeum deeply, foveately reticulate. 

 Abdomen black, apical half of second tergite, tergites 3-6, base 

 of ultimate tergite, and apical fringes of sternites 3-6 laterally, 

 clothed with yellow pubescence ; remainder of abdomen with sparse,
