in the allotype is about one fifth of the head-width, in the holotype 

 about one fourth. The abdominal pile of the allotype is nearly all 

 deep black, while that of the holotype is practically all bright rufous, 

 only the tip of abdomen showing a lighter pile mixed apically with 

 black in both cases. I do not consider that these two specimens can 

 represent two distinct species, notwithstanding the differences in 

 frontal width and pile coloration, since they issued from puparia 

 which appear to be identical. Moreover, they came from a lot of 

 eight larv^ all evidently the same species. They simply furnish an 

 emphatic illustration of the scope of variation in the species of this 

 genus. 



C. pratti is distinguished from pJiobifcr practically only in retain- 

 ing the mesoscutal band of black pile and losing the infuscate area 

 of the wing, in both points conforming to the European species. It 

 differs from the European stimulator, which it closely duplicates in 

 appearance, by the narrow front of male, short discal abdominal pile, 

 and the restriction of the light pile of femora to the basal region, in 

 all three points conforming to phohifcr. The larval characters in 

 general approach closely those of nlrichii, as stated by Hunter; the 

 anal stigmata, one of the best specific guides, being practically the 

 same. This explains Brauer's determination of the larva as nlrichii. 



1913. Two flies were taken by Mr. Frank E. Watson, one on the 

 summit of Mt. Marcey, New York, 5,344 feet, on July 3, and the 

 other at North Elba, New York, in July. The latter specimen has 

 been donated to the U. S. National INIuseum by Mr. Wm. T. Davis 

 and is a male of phohifer (syn. abdominalis Aid.). Mr. Davis pub- 

 lished a note on these two specimens in 1916 (Journ. N. Y. Ent. Soc, 



XXIV, pp. 92-93)- 



1914. Three male flies taken by Mr. Wm. T. Davis on White Face 

 Mountain, in the Adirondacks, New York, were described by Dr. J. 

 M, Aldrich in 191 5 as abdominalis (Journ. N. Y. Ent. Soc, XXIII, 

 pp. 145-150, pi. II). This was the first record to be published on 

 Cephenemyia flies of American origin since Bracy Clark's time, and 

 was of unusual interest as indicating the rediscovery of phohifer after 

 a lapse of just one hundred years. It emphasizes the rarity of the 

 capture of these flies. Clark's description and figure seem to leave 

 no doubt of the identity of the species. The available data indicate 

 quite positively that the discal abdominal pile of Clark's specimen was
