Two specimens. Allied to M. californica, but is distinguished by 

 the color of the body being rufo-piceous, instead of black, and by the 

 abdomen having only the large basal segment reddish above. 



12. Mutilla JEgina, n. sp. 



Rufo-piceous: head, thorax and large basal segment above, except extreme 

 base, with reddish pubescence, the. remainder with black pubescence. 



Female. — Very closely allied to M. Bellona, from which it differs 

 only by having the pubescence of the legs and of the abdomen, except 

 on the large basal segment above, entirely deep black, and the segments 

 not fringed with yellowish. The pubescence of the head, thorax and 

 large basal segment of the abdomen above varies to yellowish-ferrugi- 

 nous. Length 6 lines. 



Two specimens. 



13. Mutilla Asopus, n. sp. 



Black; head and thorax above and the large basal segment of abdomen red, 

 clothed above with bright red pubescence: metathorax tinged with reddish; 

 wings blackish ; large basal segment of abdomen beneath with a sharp longi- 

 tudinal, central carina. 



Male. — Black, with large, close, deep punctures, and long black 

 pubescence; head, above the antennae, clothed with long red pubes- 

 cence ; eyes small, rounded, entire and convex ; antennae black at base, 

 the flagellnm brown-sericeous. Thorax ; prothorax, mesothorax and 

 scutellum rufous and clothed with long, dense bright red pubescence ; 

 pleura and metathorax rufo-piceous, the latter more reddish at base, 

 reticulate with coarse punctures and clothed with long thin black pu- 

 bescence ; teguloe with reddish pubescence. Wings blackish, paler 

 about the middle, with a subhyaline dash in the second submarginal 

 and second discoidal cells ; marginal cell short, very abruptly and 

 broadly truncate at tip ; two distinct submarginal cells, the first as long- 

 as the marginal, the second a little shorter, receiving the first recurrent 

 nervure about the middle; the third submarginal cell obsoletely defined. 

 Legs entirely black, with black pubescence. Abdomen ovate, gradu- 

 ally narrowed behind, the punctures not so large as those of the thorax; 

 large basal segment rufous, less bright beneath, with a blackish longi- 

 tudinal stripe on the dividing suture between the dorsal and ventral 

 surface, the dorsal surface, except extreme base and apex, is clothed 

 with a dense bright red pubescence ; on the rest of the abdomen, the 

 pubescence is deep black ; large ventral segment with a central longi- 

 tudinal carina, more sharply developed on the posterior half of the seg- 

 ment. Length 5} lines; expanse of wings 91 lines. 



One specimen. May be the % of M. jEgina, as it resembles that 

 species in the distribution of color.
