may be the male of either dilucida or chrysocoma. The paratype 

 is much smaller than the type, its length being 7 mm.

SPECIMENS EXAMINED 



Texas: Male. 



The black pubescence of the mesonotum and the apical abdominal 

 segments and the greatly developed, glabrous, lateral processes of 

 the scutellum, distinguish it from related species. The type has 

 been examined and this specimen found to be identical with it. 



120. DASYMUTILLA DIGRESSA, new species 



Male.— Head and thorax black, abdomen ferruginous; front 

 vertex, pronotum, anterior margin of mesonotum and scutellum 

 with silvery gray pubescence, remainder of head and thorax with 

 black pubescence; apical fringe and pubescence of apical half of 

 second abdominal tergite black, pubescence of remainder of abdomen 

 pale; first segment of flagellum distinctly shorter than the second; 

 lateral processes of scutellum small, punctate ; middle and hind femora 

 squarely truncate at the tip, the surface of the truncations sulcate; 

 calcaria pale. Length, 11 mm. 



Head black, clothed with sparse, long, erect, black pubescence, 

 except the front and vertex with sparse, long, erect and appressed, 

 silvery gray pubescence ; mandabies acute at the tip, apparently not 

 dentate within; anterior margin of clypeus very strongly dentate 

 medially; disk of clypeus densely, confluently punctuate; scape 

 bicarinate beneath, one carina strong, the other very weak, punc- 

 tate above; first segment of flagellum distinctly shorter than the 

 second; antennal scrobes carinate above; front densely, confluently 

 punctate; vertex densely but not confluently punctate; genae with 

 moderate, more or less separated punctures; relative widths of head 

 and thorax, 5.5-6.25.
