Dasymutilla 'permista Mickel from a cocoon of Elis quinquecincta 

 Fabricius several years later. Is is possible that permista may be 

 the male of quadriguttata but it does not seem probable inasmuch as 

 quadriguttata does not occur east of Minnesota, Illinois, and Missis- 

 sippi, while permista occurs east to the Atlantic coast. If permista 

 should prove to be the male of quadriguttata, the latter must be repre- 

 sented in the east by some female closely related to it. Such a species 

 is interrupta. What the real relationships of quadriguttata, per- 

 mista and interrupta are, remains to be determined and until these 

 relationships are definitely known it is best to regard each as a 

 single species. The specimens of quadriguttata at hand vary in 

 length from 7 mm. to 15 mm.

This species has been identified in all collections as cypris but an 

 examination of the type of the latter has shown that the name cypris 

 should apply to the specimens which have been described by Rohwer 

 as mutata miam^nsis and by Bradley as ruhicunda. 



The description of this species is as follows : 



Female. — Ferruginous, very sparsely clothed above with recumbent, 

 golden yellow pubescence; the second abdominal tergite sparsely 

 clothed with black, recumbent pubescence except a pair of small, 

 basal, pale ferruginous spots and a pair of large, apical, pale ferrugi- 

 nous spots with golden yellow pubescence; apical fringes of abdomi- 

 nal tergites 2-5, and pubescence of body at sides and beneath, silvery 

 gray; postero-lateral angles of head, each with an oblique, subrec- 

 tangular, glabrous tubercle; posterior margin of head slightly con- 

 vex; pygidium longitudinally striate, the striae continuous to the 

 apical margin ; length, 9 mm.
