THE 3[ALARIAL MOSQUITOES 113 



The North American Species of Anopheles. 



So far as known at the present time we have but three 

 species of the mahirial g-enus in the United States, namely 

 A. rnacuUpetirds Meigen (equals A. qaadmiiaculatus Say), 

 A. 2Ju?ictipe?in:is Say, and A. crucians Wied., although Mr. 

 Theobald, in his monograph, which will include the mos- 

 quitoes of the world, will describe forty-two species of this 

 genus, and possibly more. 



A. 7/iaculi2)en7m is a rather insignificant species, 

 which is well illustrated in Figure 15, its wings being 

 nearly clear, but marked Avith four rather small dark 

 spots composed of groups of darker scales. Its palpi are 

 entirely black. 



A. 2>(nidi2Miuiis is our handsomest species, and has a 

 yellowish white spot occupying about three-fourths of 

 the length of the front margin of the wing. The scales 

 on the last vein are white and those at each end black. 



A. crucians has the palpi marked with white at the 

 bases of the last four joints, and the scales of the last 

 wing vein wliite, marked with three black spots. The ac- 

 companying figures will enable a much readier differentia- 

 tion of this species than will any description. 



As to distribution,^. 7)iaculipen?iis and A. 2nincti2)ennis 

 are found almost everywhere in this country. I have seen 

 specimens of A. maculi2yennis from New Hampshire, Con- 

 necticut, New York, District of Columbia, Maryland, Vir- 

 ginia, Florida, Texas, Louisiana, Indiana, Illinois, Min- 

 nesota, and Oregon. Dr. A. S. Packard has recorded its
