INVESTIGATIONS ON THE MUTILLID WASPS 297 



less separated punctures, clothed with rather sparse, erect, very pale 

 yellowish pubescence; apical tergite with a fringe of pale yellowish 

 pubescence at the base, indistinctly rugose ; first sternite with a promi- 

 nent median carina, the latter somewhat dentiform posteriorly; 

 second sternite with large, elongate punctures at the sides, very small 

 sparse punctures medially; sternite 3-6 with small, confluent punc- 

 tures along the apical margins ; sternites 2-5 with a thin apical fringe 

 of pale yellowish pubescence. 



Legs mahogany red, clothed with brownish pubescence. 



Wings fuliginous; cell K4 present, but indistinct. 



Eolotyj)e.—M2i\e^ San Bernardino Ranch, Douglas, Arizona (F. H. 

 Snow), in collection of University of Kansas. 



Superficially this species resembles subMjalina very much, the 

 distribution of pale pubescence being almost the same in the two 

 species. However, it lacks the large eyes and ocelli, and the sub- 

 hyaline wings of suhhi/alina, and obviously is not closely related to 

 that species. 



It is difficult to determine whether the yellowish cast of the pubes- 

 cence is natural or whether it is due to staining during the collecting 

 process. It is possible that in nature the pale pubescence is pure 

 white. 



136. DASYMUTILLA DORIPPA, new species 



Plate 5, fig. 37 



Male. — Black; clothed with black pubescence, except vertex, dor- 

 sum of thorax and abdomen above from and including apical 

 half of second tergite clothed with yellow pubescence; ocelli very 

 large and conspicuous, but eyes of normal size ; last tergite with an 

 apical fringe of erect hairs; second sternite without a median pit 

 or row of hairs simulating a carina. Length, 13 mm. 



Head black, clothed with black pubescence, except the front and 

 vertex clothed with sparse, erect, yellowish pubescence; mandibles 

 acute at the apex, bidentate within near the apex ; clypeus bidentate 

 medially on the apical margin ; disk of clypeus densely, finely punc- 

 tate ; scape bicarinate beneath, densely punctate above ; first segment 

 of flagellum subequal in length to the second; antennal scrobes 

 distinctly carinate above ; front densely, confluently punctate ; vertex 

 and genae closely, more or less confluently punctate; ocelli very 

 large and conspicuous, the median ocellus larger than the lateral 

 ocelli and separated from the latter by about its own diameter; 

 relative widths of head and thorax, 8-10.25. 



Thorax black, clothed with long, erect, black pubescence, except 

 the pronotum, mesonotum, scutellum and postscutellum clothed with 

 long, erect, yellow pubescence; propodeum with black pubescence
