on pronotum, and four anterior legs below trochanters, except a line 

 on femora, reddish-yellow (the reddish tint may be due to potassium

 venation dark brown. 



Brownsville, Texas. 



Type. — In the Museum of the Brooklyn Institute, New York. 



Orbital carina strong, the area between it and the eye margin 

 foveolate. 



Genus CRABRO Fabricius. 



CRABRO (SOLENIUS) TOWNSENDI, new species. 



Allied to the North American species interruptus and cinctibellus, 

 but much different in the sculpture of the propodeum. 



Female. — Length nearly 11 mm. Production of the clypeus 

 broader at the apex, the emargination very shallow; facial fovea 

 very narrow and deep, without a bounding carina above but never- 

 theless well denned; ocellar line subequal with the ocellocular line; 

 supraorbital fovea as long as first two joints of the flagellum; head 

 with close, large, distinct punctures, the punctures of the front a little 

 larger than those of the cheeks; first joint of flagellum a very little 

 longer than second; pronotum sharply carinated, the lateral tooth 

 small; dorsulum striato-punctate, anteriorly a few distinct punctures; 

 scutellum striato-punctate; mesopleurae striato-punctate above; 

 below mostly punctured though there is a tendency to striation; 

 propodeum dorsally and posterior face strongly striato-reticulate; 

 the broad median furrow foveolate; strongly longitudinally, propo- 

 deum laterally striate; legs and venation normal for Solenius; abdomen 

 with strong, distinct, rather close punctures, larger on the first seg- 

 ment and becoming smaller apically; apical margins of the first two 

 segments somewhat depressed; pygidal fringe thick. Black; tegulae 

 rufotestaceous; scape, two elongate spots on pronotum, tubercles, 

 two oval spots on scutellum which meet, four anterior knees, all the 

 tibiae and tarsi, elongate spots on the firsc three dorsal segments 

 (narrowly separated) and bands on the fourth and fifth dorsal seg- 

 ments yellow. Wings f usco-hy aline ; venation pale brown, stigma

CRABRO (subgenus?) SCHWARZI, new species. 



Very distinct and belonging to an undescribed subgenus, falling 

 near Metacrabro and Xylocrabro. Easily known by the head nar- 

 rowing behind eyes, the occiput margined, and coarse sculpture. 



Male. — Length 8 mm. Clypeus strongly carinated; distance 

 between the eyes at the clypeus slightly less than the length of the
