NEW SPECIES OF WASPS— ROHWER. 



467 



Two males from Springfield, Idaho, collected July 30, 1906, by 

 Mr, A. J. Snyder. 



BEMBYX CAMERONI, new species. 



Related to spinolse Lepeletier. Differs from the original descrip- 

 tion of this species in some minor points of coloration, viz, anus with 

 a pale spot. From Handlirsch's interpretation of spinohe the shape 

 of the gentaha stipes and dentation of 

 the antennae will separate it. 



Male. — Length 17 mm. Labrum not 

 depressed; vertex, seen from in front, 

 biemarginate ; head with very sparse, 

 irregular punctures; apex of flagellum 

 dentate beneath, as in figure 4 ; the first 

 joint slightly longer than the two follow- 

 ing; thorax finely granular; legs prac- 

 tically as in spinolse, except that the 

 anterior femora are more robust and 

 sUghtly flattened beneath; second and 

 seventh ventral segments -with large, sim- ^i«- 4.-apical joints of the flagel-

 bles (except piceous apices), inner orbits broadly 

 to near vertex, supraclypeal area, scape in front, 

 tubercules, tegulae, legs below bases of femora, 

 large spots on first dorsal, sinuate bands on the sec- 

 ond, third, fourth, and fifth dorsal segments, con- 

 tinuous band on sixth and a spot on seventh dorsal, 

 small lateral spot on second and following ven-

Named for Mr. P. Cameron, the writer on this group of insects 



in "Biologia Cen trali- Americana. " 



BEMBYX OBSOLETA Howard. 

 Bembex obsoleta Howard, Insect Book, 1904, pi. 4, fig. 36. 

 This species has never been described, but the figure is enough to 

 hold it, and the type must be the actual specimen figured, which is 

 in the U. S. National Museum definitely labeled as such.
