9 . — Head large, uot lower tlian usual when seen from the front, strongly pro- 

 duced behind the eyes, with tolerably close and coarse punctures, closest and 

 finest in front : impressed line extendinfj from fore ocellus to the frontal depres- 

 sion tolerably distinct; ocelli as usual, the space between hind pair less than that 

 between them and the nearest eye-margin; pronotum strongly margined ante- 

 riorly, subangular laterally; dorsulum with coarse punctures, closest anteriorly ; 

 sciitellum more spai'sely and less coarsely punctured ; mesopleune coarsely striato- 

 punctate throughout ; middle segment with the medial furrow narrow, not deep, 

 closely punctato-striate, above the striae rather indistinct, on posterior face stronger 

 and transverse, lateral ridges not developed, sides almost smooth, though evi- 

 dently delicately striated, the upper ridge not very strong ; abdomen distinctly 

 punctured, the first dorsal segment rather coarsely so, second ventral with large 

 separated punctures. Black ; mandibles except apex, scape, two large spots on 

 pronotum, tegulje, scutellum more or less, and a small lateral spot just anterior 

 to it, metanotum more or less, femora above in part, tibise, tarsi (the apical joints 

 darker), spot on each side of abdominal segments 13, those on segments 1 and 2 

 shortest, broadest and more or less obtuse within, those on the third segment long, 

 narrow, pointed internally, and a band on segments 4 and 5, yellow ; the femora 

 are in part also rufous and sometimes are entirely of that color and yellow ; tro- 

 chanters sometimes rufous or yellowish ; head and thorax scarcely pubescent ; 

 wings paler than in viUosus, nervures and stigma testaceous. Length 10-13 mm. 



% . — Veiy much like the 9 , but more coarsely sculptured, particularly the 

 abdomen ; first joint of medial tarsi as long, or longer than the following two 

 united, slightly produced at apex, not at all angular; second joint more strongly 

 produced at apex, somewhat curved ; colored as in the other sex, but no spots on 

 scutellum, and the abdominal marks narrower. Length 8-11 mm. 



Illinois, westward to Montana, south to Nebraska ; eastAvard to 

 Massachusetts, south to New Jersey, north to Canada. I have re- 

 ceiv^ed this apparently common species from most of my correspon- 

 dents. Its geographic distribution is no doubt greater than the 

 material at hand indicates. 



31. Crabro villosus n. sp. 



9 . — Head low, when seen from the front, strongly transverse, but little 

 produced behind the eyes, with very clo.se, tolerably coarse punctures, or the sculp- 

 ture particularly that of the front may be described as granulated; impressed 

 line extending from fore ocellus to frontal depression indistinct ; hind ocelli placed 

 behind an imaginary line drawn across the vertex from the outer orbit of one 

 eye to the other, the space between them not quite as great as that separating 

 them from the eye-margin ; pronotum not margined anteriorly, but transversely 

 furrowed, at the sides rounded ; dorsulum with tolerably coarse punctures, which 

 are closest anteriorly ; scutellum sparsely puuctured ; mesopleurje coarsely striato- 

 punctate, sparsely so on lower portion of epimerum ; middle segment with the 

 medial furrow broad and deep, above with rather coarse sti'iations curving some- 

 what to the sides, the posterior face roughened and punctured, lateral ridges well 

 developed, sides less rough than the posterior face, somewhat striated, bounded 

 above by a strong ridge, which does not reach the posterior face : abdomen not
