NOTES ON THE NORTH AMERICAN SPECIES OF 

 CHOEROPORPA 



(Dipt era, Culicidce) 

 By HARRISON G. DYAR 



Since my last account (Ins. Ins. Mens., viii, 54-81, 1920), 

 some matter worthy of record has transpired.

 Culex (Choeroporpa) erraticus Dyar, Ins. Ins., Mens., viii, 55, 

 1920. 

 This species was described from the larva, Baton Rouge, 

 Louisiana. The mesonotum of the adult is commonly much 

 marked with bright golden; but a specimen from the type 

 locality (J. W. Dupree) is much abraded. The types of 

 abominator were said to be ten, including five localities. There 

 are seven specimens in the Como series, though but six are 

 called for, leaving one specimen each for the other localities. 

 The Como specimens have very little golden on the mesonotum 

 and the abdomen is without the characteristic spottings, and I 

 think they are probably not erraticus; they are at least doubt- 

 ful, and may be excluded from the types. The remaining 

 types are much worn, the golden color obscured. 



Positive records exist from Louisiana, Arkansas, Mississippi 

 and Tennessee ; the Florida record has not been confirmed by 

 male. It is doubtful, for the specimen has no gold on the 

 mesonotum. I would refer it to egberti D. & K.
