 wanting; ocellar line slightly longer than ocellocular line; head 

 strongly narrowing behind eyes, the occiput strongly margined; 

 antennae short, simple; pronotum strongly crested, dentate laterally;

 posterior face transversely so ; propodeum laterally rather strongly lon-

Cacao, Trece Aguas, Alta Vera Paz. Guatemala, March 23, 1906. 

 One male collected by Schwarz (for whom the species is named) and 

 Barber. 



Type.— Cat. No. 13742, U.S.N.M. 



CRABRO (HOPLOCRABRO) FERRUGINEIPES Rohwer. 



This species was described from a single male collected at Pecos, 

 New Mexico. From the C. H. T. Townsend collection of Meadow 

 Valley, Mexico, there are five males and four females. The female is 

 much like the male but is of course larger and has the antennae 

 simple. 



CRABRO (HOPLOCRABRO) NOVANUS, new species. 



Of the described Mexican species perhaps this is more like sonorensis 

 Cameron, but is at once distinguished by the sculpture. Belongs in 

 with decemmaculatus Say, but may be known at once by the sculpture 

 of the propodeum. 



Female. — Length 13.5 mm. Anterior margin of the clypeus 

 slightly produced into a truncate process, middle carina strong; facial 

 fovea as on Hoplocrabro, as is the rest of the head; post ocellar line a 

 little shorter than ocellocular line; third joint of antennae distinctly 

 longer than fourth; head with small close punctures, much sparser 

 on the cheeks; pronotum feebly carinated, not dentate, separated by a 

 broad furrow from mesonotum; dorsulum with rather close, distinct 

 punctures; scutellum more sparsely punctured; mesopleurae striato- 

 punctate; propodeum dorsally with rather large, well separated, dis- 

 tinct punctures; median furrow broad, well denned, striolate; posterior 

 face with separate striato-punctations; propodeum laterally very finely 

 longitudinally striate ; legs robust ; first dorsal segment with scattered,
