AMERICAN HYMENOPTERA. 22* 



Descriptions of New Species of* HYMENOPTERA taken 



by Mr. Edward Whyiuper on the "'Higher 



Andes of the Equator." 



BY P. CAMERON. 



(New Mills, by Stockport, England.) 



The circumstances under which the Hymenoptera described here- 

 with were taken are related by Mr. Whymper in his "Travels 

 amongst the Great Andes of the Equator," 1892, p. 856. The 

 parasitic species I have described in "The Entomologist" for the 

 present year. 



SCOLIID.E. 

 t'ainpsomeris (Elis) ephippiuin Say. 



The form taken by Mr. Whymper is C. Wagneriana Saussure, 

 which was described from Chimborazo. It differs from the type in 

 having the wings clear, or almost clear, hyaline; whereas in the 

 type they are dark fuscous violaceous. The orange bands on the 

 abdomen are paler than in the type. The species was taken by Mr. 

 Whymper at Betiocen, Pinantura and Antisanella, 11,000 feet; 

 Guallabamba to Guachala, 7500 feet, and Ambato, 8000 feet. 



The var. Wagneriana is probably a high-mountain form. It is 

 figured by Mr. Whymper in his travels, p. 96, and he mentions there 

 that it is known by the name of "the Bishop." 



CampMomeris (Elis) costalis Lep. 

 One example of this common neotropical species from 8. Lucia, 

 8000 feet. 



Caiiipsomeris (Dielis) argenteopilosa sp. nov. 



Black; the head and thorax densely covered with silvery pubescence and with 

 black hair; the apices of the second and third abdominal segments fringed with 

 white hair; the wings hyaline, the radial cellules tinged with dark fulvous; the 

 radial cellule long, projecting largely beyond the cubital. % . Length 20-21 mm 



Head punctured, except for a broad curved line on the top of the front and 

 the clypeus, except round the sides and tojt ; the smooth parts are bare ; the rest 

 punctured and bearing stiff black hairs; the occiput and outer orbits are thickly 

 covered with pale hair. Mesonotmn punctured closely, but not strongly; the 

 apical part in the middle smooth. The scutellum is similarly punctured, except 

 in the middle which is smooth, the smooth part being broadest at the apex. The
