6. FORCIPOMYIA PERGANDEI Coquillett 

 CeratopogoH pergandci Coquillett, Proe. U. S. Nat. Miis., Vol. 23, 1901, p. 602. 



This species differs from a urea in being much darker in color, the 

 abdomen having only the apical third of dorsal segments yellow, and 

 in having the legs considerably blackened. The male is very simi- 

 lar to that here described as aiirea, but the antennal and hind tarsal 

 proportions are quite dissimilar (PI. XXI, Fig. 5). The hypopygium 

 is similar to that figured for aurca. 



Length, 2.5-2.75 mm. 



Illinois localities, Grand Tower, April 22, 1914, and Urbana, July 

 7, 19 14, both at light (C. A. Hart and J. R. Malloch). 



Originally described from the District of Columbia. 



The larva of what I consider as the typical form of this species was 

 taken by Prof. A. D. MacGillivray under bark of a fallen tree. Larval 

 and pupal details are given in Figures 15, 8, and 21 of Plate XVIII. 



Var. concolor, n. var. 



Similar to the foregoing except that it is noticeably smaller, 1.75 

 mm., and has the dorsum of the abdomen without distinct pale post- 

 marginal band to the segments. 



Localities, Grand Tower, along with the type form, and Urbana 

 July 4-7, on windows (C. A. Hart and J. R. Malloch). 



Palpomyia Meigen 



I have recently revised this genus in the Bulletin of this Labora- 

 tory,* and herewith present a synopsis of the species with such altera- 

 tions and notes as are recjuired to bring our information up to date. 



Since the publication of the paper referred to I have succeeded in 

 obtaining several additional species which have caused me to change 

 the generic location of some of those I had placed in Palpomyia. I 

 suggested in the previous paper that riifa Loew might belong to the 

 genus Heteromyia, and I find this to be the case on examination of a 

 specimen from Ithaca, N. Y. I have also removed trivialis Loew to 

 Heteromyia. 



My knowledge of the early stages of the species of this genus is 

 not sufScient to warrant even an opinion as to whether the larvae or 

 the pupae may be separated from those of allied genera by any charac- 

 ters which the species possess in common.
