Becords of Bees. 425 



San "Rafael, Jicoltepec, Mexico. U.S. National Museum. 

 From the Ashmead collection ; no doubt collected by C. H. 

 T. Townsend. 



Resembles P. mexicana, Cresson, but easily separated by 

 the linear lateral face-marks, and other characters. It is 

 evidently closely allied to P. maculipennis, Smith, known 

 only in the male, but that has yellow markings aud the 

 first abdominal segment rather strongly punctured. 



Prosopis knabi, sp. n. 



S . — Length about 3*75 mm., anterior wing 3. 



Black, with yellow markings ; scape black, broadly red 

 at end, and largely in front ; flagellum entirely bright 

 ferruginous, a little darker above ; clypeus entirely, sub- 

 triangular supraclypeal mark (broader than long), and lateral 

 face-marks ail light yellowish, the latter ending obtusely on 

 orbital margin about halfway up front (former practically 

 as in P. episcopalis, Ckll.) ; pale marks of thorax confined 

 to tubercles and a broadly interrupted line on prothorax 

 above ; tegulse testaceous, hyaline in front, with a yellow 

 spot ; mesothorax closely and strongly punctured, scutellum 

 rather more sparsely, the surface between the punctures 

 smooth ; base of metathorax .with strong longitudinal and 

 transverse rugae, but the sculpture is mainly and essentially 

 transverse ; whole sides of thorax strongly punctured, the 

 metathorax at sides bare (without grey tomentum) ; knees, 

 anterior tibiae (except a large patch behiud), middle and 

 hind tibia?, very broadly at base and narrowly at apex, and 

 the tarsi all pale yellow. Wings clear; stigma and nervures 

 sepia ; first recurrent nervure joining first submarginal cell 

 a short distance before its end. Abdomen appearing im- 

 punctate under a lens, but the microscope shows minute 

 punctures on first segment. 



Champerico, Guatemala, Aug. 4, 1905 [Frederick Knab). 

 U.S. National Museum. 



This minute species recalls some of those of the United 

 States, such as P. modesta, Say, but it will be readily 

 known by the red flagellum and transverse rugse at base of 

 metathorax.
