 S. Dakota and Illinois. It is found mostly in early Spring and 

 late Fall. The larva feeds on putrefying animal matter. 



I have four specimens of a Cynomyia from Greenland which I 

 refer, with a doubt, to this species. They are imperfect, but 

 seem, on the whole, a little more like C. mortuorum than ameri- 

 cana ; possibly they represent a new species. The following 

 points clearly distinguish this species from C. mortuorum ; The 

 face of americana is brownish yellow, that of mortuorum golden- 

 yellow, and in the latter the yellow color extends much further

 The hypopygium and its terminal hooks are of moderate size in 

 americana, very large in mortuorum, and on this account the 

 abdomen of mortuorum seems more elongate. The normal 

 chaetotaxy is identical, except that americana has two posterior 

 achrostical macrochaetae, mortuorum but one. 



Cynomyia elongata nov. sp. — Length twelve to fourteen millimeters. 

 Resembles americana so much that I shall limit my description mainly to 

 pointing out the differences between the two. Front of male one-fourth 

 the width of the head, in americana one-fifth. According to the inci- 

 dence of the light the color of the frontal vitta varies from dark brown to
