in numbers about two weeks later at 4000 feet. A. Cybele, however, is 

 rare, and I saw only a single specimen, which was smaller than the asso- 

 ciated Aphrodites, although Cybele is represented by really huge examples 

 in the warmer valleys of Virginia. The single specimen of A. Diana was 

 seen at 3800 feet, at which level E. Claudia is not uncommon. P. Tharos 

 is found occasionally ; Pyrameis Atalanta and Huntera were seen on the 

 topmost crags, as well as lower levels. Limenitis Ursula frequented the 

 roads ; Thecla Humuli, Chrysophanus Americana, Lycaena Comyntas, 

 with an occasional L. Pseudargiolus, represented the Lycaenidte ; and a 

 few Hesperidas were seen, but not collected. 



The list is noteworthy, chiefly for the absence of nearly all the butter- 

 flies characteristic of the latitude, and of many others which one would 

 expect to meet in so favourable a mountain region. It is possible that 

 some of these missing species may be found in the early spring, when the 

 mountains are said to be one blaze of colour with Azaleas and 

 Rhododendrons and all manner of vernal blossoms. These butterflies 

 may lay their eggs early — so that the larvae may have the whole season to 

 grow — -and then disappear ; but this is mere conjecture, based on the well- 

 attested abundance of early flowers of gay colours well suited for butterfly 

 fertilization. 



A NEW GENUS OF UIPTERA ALLIED TO RHAPHIOMIDAS. 



BY D. W. COQUILLETT, LOS ANGELES, CAL. 



In the " West American Scientist" for January, 1891, I gave a brief 

 description of Rhaphiomidas acton n. sp., comparing it with the only 

 other described species, R. episcopus O. S. The description was drawn 

 from a single male specimen now in the National Museum at Washington, 

 but during the past season I was fortunate enough to capture four ad- 

 ditional specimens of this species, three males and a female, all of them 

 having been taken on the wing while hovering over flowers in the hottest 

 part of the day, the time being the first week in July. The possession of 

 these specimens permits me to make a few corrections to my published 

 description. In profile, the lower edge of the third antennal joint is not 

 conspicuously less convex than the upper edge, and the tip is pro- 

 vided with a minute tubercle (this may have been broken off in the 

 type specimen) ; the three ocelli are shining, but sometimes lose their 

 lustre in drying ; the relative length of the fifth, sixth and seventh ab-
