Closely related to canso Blake and Mrkmami Melander. Differs 

 from those species in the dense, very pale golden pubescence of the 

 head and thorax, the maculation and sculpture of the second tergitc 

 and the color of the pubescence of the third tergite. The paratype 

 is smaller than the type, its length being 5 mm. 



80. DASYMUTILLA BONITA, new species 



Female. — Ferruginous, coarsely sculptured throughout, and 

 sparsely clothed with silvery pubescence; second abdominal tergite 

 with very large, contiguous, foveate punctures, and a submedian 

 spot of black pubescence ; apical fringes of second and third abdom- 

 inal tergites pale, interrupted medially by a small spot of black 

 pubescence ; length, 7 mm. 



Head ferruginous, clothed throughout with sparse, erect and re- 

 cumbent, silvery pubescence, and a few, scattered, erect, black hairs; 

 mandibles acute at the apex, weakly unidentate within; anterior 

 margin of clypeus not noticeably bidentate medially ; anterior half of 

 clypeus glabrous, impunctate, separated from the posterior half by 

 a sinuate carina ; the posterior half punctate and sparsely clothed with 

 long, pale pubescence, the latter forming a clypeal fringe; antennae 

 dark ferruginous; scape with moderate, indistinct punctures; first 

 segment of flagellum about twice as long as its own width at the apex, 

 and almost equal beneath to segments three and four united ; antennal 

 scrobes not carinate above ; front and vertex with large, coarse, more 

 or less confluent punctures; genae with moderate, more or less con- 

 fluent punctures ; relative widths of head and thorax, 5-5.5. 



Thorax feruginous, sparsely clothed throughout with silvery pubes- 

 cence and scattered, erect, pale hairs, except the disk of the pronotal 

 area, and a small area anterior and posterior to the scutellar scale, 

 with sparse, black pubescence ; dorsum of thorax and propodeum with 

 coarse, large, contiguous punctures, the punctures larger and deeper 

 on the propodeum than on the dorsum of the thorax; scutellar scale 

 well-developed; propleura with large, indistinct punctures near the 

 margins, very small, indistinct punctures on the disk; anterior half 

 of mesopleura finely punctate, the posterior half with large, confluent 

 punctures, the posterior margin of the latter with dense, silvery 

 pubescence ; metapleura with large, confluent punctures near the ven- 

 tral margin and fine punctures elsewhere, the ventral half of the 

 posterior margin with dense, silvery pubescence; sides of propodeum 

 with very large, close punctures. 



Abdomen ferruginous; first tergite short, nodose, the disk glabrous, 

 impunctate, the posterior fourth with large, deep, contiguous punc- 

 tures; clothed with scattered, erect, pale hairs and a conspicuous, 

 transverse spot of dense silvery pubescence at the apical margin;
