16 PROCEEDINGS OF THE NATIOjSTAL MUSEUM. vol. G4 



In tlie above series are specimens from Canada, Connecticut, Long 

 Island, New York, Illinois, Colorado, South Dakota, and Idaho. 



OPHELTES GLAUCOPTERUS, variety BARBERI, new variety. 



Female. — Differs from Jlavipennis in its larger size (26-27 mm,), 

 more strongly swollen and wider temples, darker yellow wings with 

 the apices deeply infnmate and from most individuals of Jfavipennis 

 in having that portion of the mesopleurum above the furrow, the 

 propodeum dorsally and the coxae almost entirely red. 



Type-locality.- — Plummer Island, Maryland. 



Type.— Cat. No. 25978, U.S.N.M. 



Two female specimens from the type-locality, both taken by 

 H. S. Barber, the type at light on July 19, 1920, and the para type 

 on July 26, 1908. 



OPHELTES MAJOR, new species. 



Female. — Length 26 mm.; antennae 26 mm. 



Closely allied to glaucopterus Linnaeus, but at once distinguish- 

 able by its much stouter form, this being especially obvious in the 

 very broad and weakly compressed abdomen. The thorax is also 

 obviously broader and deeper in proportion to its length. The 

 propodeal areola is complete, the carinae strong from their junction 

 to the apical carina; while the legs are slightly stouter than in 

 glaucopterus. 



In color it resembles typical specimens of Jlavipennis (Provancher) 

 in having the propodeum entirely black, but the black of the abdo- 

 men extends nearly or quite to the base of the fourth tergite, the 

 mesoscutum and scutellum are red, the former with a black median 

 vitta and fainter lateral vittae. The wings are deeply infumate 

 at apex. 



Male. — Essentially like the female. 



Type-locality. — Gifu, Nippon, Japan. 



Type.— Cat. No. 25979, U.S.N.M. 



Described from two females and one male, the type and allotype, 

 from Gifu, Y. Nawa, collector, and bearing his number 58; and the 

 paratype female labelled simply "Japan, Mitsukuri." 



The species apparently varies structurally in much the same 

 manner as does glaucopterus. In the type and allotype the temples 

 are very broad and swollen and the propodeum long and dorsally 

 without any indication of costulae ; while in the paratype the temples 

 are hardly broader than the eyes and the propodeum is shorter above 

 and transversely elevated in the positions of the costulae. 

 NEPHOPHELTES. new genus. 



This genus is easily recognized by the characters made use of in 

 the key. What others of its features are of more than specific sig- 

 nificance are embodied in the description of the type species. 



Genotype. — NepJiopheltes japonicus, new species.
