ANTHOMYIDAE. 165 



thomyidae of North America (Ent. Monthly jNIagazine, April 

 187JS, p. 250 — 252), I have reproduced his conclusions below, at 

 the end of each corresponding genus; compare also the note-'' 

 for the general conclusions. 



About Aricin he writes: 



The genus Policies (Kond.) of which the well-known (european) 

 M. lardaria F. is the principal species, is not represented in the 

 (North American) collection. 



„In the genus Hyetodesia (Aricia pt. Macq.). I determined 

 seven distinct (North American* species, several of which closely 

 resemble european, as Blusca lucorum Fall., A. lugxihris Meig., 

 and A. ohscurata Meig., but none of them, 1 think, are quite 

 identical." 



,,Tn the genus Mydnea (Aricia pt. Macq.). I found ten species, 

 only one of which was similar to any in Europe, viz. the common 

 M. pagana F., which has a yellow scutellum.''

Observation. Mr. Meade says (1. c.) : 

 „In Spilogaster there where eleven (North American) species, one 

 or two of which closely resembled european species, but were, 

 however, distinct. One fly in this genus possessed several inter- 

 esting characters, which deserve especial notice. There was only 

 one male in the collection and it bore a remarkable resemblance 

 to Cyrtoneura (Myospila) mcditahunda F. The fif^h longitudinal 

 vein was curved in a similar manner towards the fourth vein, 

 though in a less degree; the si)Ots upon the abdomen and the 

 general color, size and appearance, were also very like those of 

 that fly; but it differed in having the eyes naked and the arista 

 fui'nished with nmch shorter hairs."

Rob. De-voidy, JVIyod., 503; 1830. 

 „The genus was represented by three (N. A ) species , all of 

 small size , one of which was similar to Musca ambigua Fallen."
