Phaonia apicata Johannseii 



Fhaoiiki apicata Johannsen, Trans. Amcr. Eiit. Soc, xlii, ]). 396, 191(5. 

 Phaonia paUicornis Stein, Arch, fiir Naturges., 1918, abt. A, heft 9, p. 12, 1920. 



This species is common in the northeastern United States and 

 extends into Canada. I have grave doubts as to its being 

 distinct from bysia Walker. 



I have before me specimens from Mt. Equinox, \'ermont; 

 Bretton Woods, New Hampshire; New Bedford, ^Massachusetts; 

 Homestead, Iowa, and Youghall, New Brunswick, Canada. 



Phaonia bysia Walker 



Antlioimjia bysia Walker, List Dipt. Ins. Brit. Mus., pt. 4, p. 936, 1849. 



This species and the last very closely resemble Mydaea occi- 

 dentalis Malloch in habitus and color, and are often confused 

 with it in collections. Lack of sufficient material of this form 

 prevents me from attempting to decide whether or not they are 

 distinct species. 



I have seen bysia only from North Adams, Massachusetts, 

 and Ctlen House, New Hampshire, (C. W. Johnson). 



Phaonia winnemanae Malloch 



Phaonia winnemanae jMalloch, Proo. Biol. 8o(\ Wash., xxxii, p. 3, 1919. 



This species closely resembles apicata, but has the humeri, 

 posterior lateral margins of mesonotum and tarsi yellow. The 

 eyes are separated by more than the width acroi-s posterior 

 ocelli, the ])realar bristle is very long, the hind femora have 

 some weak bristles on the basal half of posteroventral surface, 

 while the hind ti])ia has two or three anteroclorsal, and four or 

 five anteroventral l)ristles, and four or five long setulae on the 

 anterior surface, as well as some shorter setulae on posterior 

 surface. 



Length, 7 mm. 



Originally described from riunnner's Island, .Maryland. 



Phaonia parviceps Malloch 



Phaonia parvircps Malloch, Trans. Amcr. Kiit. Soc, xi.iv, p. 2()7, 1918. 



Phaonia caesia Stein, Arch, fiir Naturges., 191S, abt. A, heft 9, p, 4, 1920. 



This species was originally described from one female. I am 

 now able to present the description of the male.
