HENRY L. VIERECK. 401 



C'rabro einctibelliis n. sp. 



Predominating color black ; pubescence golden and mostly incon- 

 spicuous. 



9 . — 10 mm — Head. — Very as in bellus, its scrobe vvliich is nearly as long as the 

 first joint of the flagel and nearly four times as long as wide, lies parallel to the 

 inner eye margin, from which it is si'parated by a space about equal in width to 

 the shortest diameter of the scrobe itself, the posterior edge of the scrobe is prac- 

 tically tangent to an imaginary line drawn across the vertex immediately ante- 

 rior to the posterior ocelli ; front, clypeus and malar space witii conspicuous pu- 

 bescence; scape and pedicel almost entirely yellow. 



T/wivix.^Propodeuin nearly as in interruptus, its dorsal aspect separated from 

 the posterior aspect by an impressed line rather than a series of foveee : tibite and 

 metatarsi almost entirely yellow, pronotu'm yellow, excepting a medial quadrate 

 black space, which separates the yellow into two parts, two oval yellow spots on 

 the scutel, tubercles and tips of femora yellow ; tarsi mostly brownish, as are the 

 claws; wings transparent and brownish, stigma and nervurcs of anterior margin 

 and basal half of the wing brownish testaceous, remainder of nervures brown. 



Abdomen. — With a transverse band on each of the dorsal segments, except the 

 apical one, yellow; excepting the band on the penultimate segments, the bands 

 of yellow are narrower in the middle than lateriilly; the dorsal segments have 

 the greater part of the apical fourth depressed below the level of the remainder 

 of the segment, th's depressed portion as well as the basal third of the segments 

 are not yellow, pubescence quite conspicuous on the apical segment. 



%. — 8.5 mm. — SnfHciently like the opposite sex, to be recognizable by com- 

 p? risen with the description of the latter, the posterior aspect of the nietathorax 

 i.s mo 'e rugose than in the female and not separated from the dorsal aspect by 

 an impressed line or a series of fpvese; each of the dorsal abdominal segments 

 has a yellow band analagous to that of each of the segments 1-5 in the female, 

 but with the band on the first, second, third and seventh segments interrupted 

 by a narrow brown line. 



Type. — University of Kansas. 



Type locality. — Thomas' Ranch, Oak Creek Canon, 6000 ft., 20 

 miles soutlivvest of Flagstaff, Coconino Co., Arizona. 



One $ paratopotype is somewhat larger than the type. Two 

 male paratopotypes seemingly differ from the type only in having 

 all the yellow abdominal bands except the apical one entite. 



Taken in August, 1902, by F. H. Snow, 



('rabro papagoruni n. sp. 



Related to nigrifrons. Black, with yellow markings, 



9. — 10 mm. — Head. — Presumably very much the same as in nigrifrons. 



Thorax. — Pronotum and tubercles very likely as in nicjrifrons, or nearly so; 

 dorsuliini and scutel so closely punctured as to appear granular although mani- 

 festly punctate in certain parts, mesopleura as, \x\ nigrifrons ; nietathorax above 

 as in nigrifrons, with exception of the longitudinal furrow, wliich is not much
