103. IVIiitilla albicincta n. sp. 



%i . — Palecastaueous, alidominal segments 3 and following fuscous; oeel 1 a r region 

 black ; head considerahly narrowed and produced behind eyes, so that when 

 viewed from above it has a somewhat triangular form, punctures not strong, 

 scattered ; antennae nearly as long as head and thorax ; space between hind ocelli 

 a little greater than that between them and eyes; mesopleurse with an irregu- 

 larly oblique ridge from base of wings downward ; first abdominal segment with 

 coarse, scarcely confluent punctures, nodose, but not strongly, being rather more 

 of a strongly convex form at apex, longer and narrower than in helicaon, but still 

 not as long as middle segment; punctures of rest of abdomen sparse and not 

 very strong, those on second ventral strongest; wings subhyaline, not yellowish, 

 stigma dark, nervures pale; entire insect clothed with erect, white pubescence, 

 and apex of segments 1-6 with a fringe of white pubescence. Length 11 mm. 



Arizona. One example. 



104. iTIutilla brevicoruis n. sp. 



%. — Castaneous; apical segments but little, if anything, darker; legs and 

 antennse testaceous ; head with separated punctures, rather square when viewed 

 from above in consequence of not contracting very much behind eyes, posterior 

 margin rather evenly rounded ; space between hind ocelli less than that between 

 them and eyes; antennae short, about equal to length of head and that portion 

 of thorax anterior to middle segment; dorsulum with large, separated punc- 

 tures; mesopleurae not ridged ; first abdominal segment with large, well-separated 

 punctures, rather broad and strongly convex, rather than nodose at apex ; .second 

 segment above sparsely, beneath strongly punctured, remaining segments finely 

 and closely; wings subhyaline, nervures pale, stigma darker; entire insect with 

 erect, pale (not white) pubescesce, apex of second or second and third segments 

 with a fringe of white pubescence. Length 11 mm.

 and legs paler than thorax ; head rather well produced behind eyes, not much 

 contracted, subrouuded, punctures strong and separated ; space between hind 

 ocelli distinctly less than that between them and eyes; antennae shorter than 

 head and thorax, its length somewhat greater than the head and that portion of 

 thorax anterior to middle segment; first abdominal segment broad, widened at 

 least three times apically, strongly convex, the punctures confluent basally, dis-
