stout as the femora. Facii tibia lias an elongate bare space on inner side 

 on basal half. Wings hyaline, rather narrow at base. Costa distinctly 

 thickened at tip of first vein. Fourth vein not sharply angulate. Incision 

 at tip of fifth vein well marked. 



Austin, Texas, May, 1900. 



This species is readily recognized by the peculiar ornamenta- 

 tion of the male fore tarsus and the configuration of the pos- 

 terior tibiae. The front tarsi approach most closely to D. 6- 

 articulatits L,w. from which they differ by their very small 

 appendage. It is a peculiar form. 



A New Callimorpha. 



BY H. D. MERRICK. 



I wish to describe through the NEWS what appears to be a 

 new variety of Callimorpha lecontei, for which I propose the 

 name ' ' dyan'i ' in remembrance of the many courtesie- 

 show r n to me by Dr. Dyar during a recent visit to the 

 National Museum. 



In color, this fly is a uniform creamy yellow, with all the 

 markings of Iccontfi. It appears with it together with an 

 immaculate form similar to vcstalis, but of the same yellow 

 tint. I have taken this fly for three seasons, near New 

 Brighton. Pa. 



1 IIAVK lately received a note from a very intelligent and observing 

 teacher, whom I asked to note the positions of the baggy and slender 

 Cecropia cocoons in a region where they abound. She says that the baggy 

 otu-s were high as well as low, " about even," while all the slender ones 

 were low. She sent me between fifty and sixty after supplying some of 

 the teachers, so she had a fair amount of material to observe. I have 

 been testing these by weight, and so far I find that the heavier cocoons 

 always gave 9 9 an< J tne lighter ones c?c?. The slenderest cocoon \va^ 

 one of the heaviest and gave a 9- 



With my present supply of cocoons I have not failed to select the 9 by 

 weight, nor have I found any difficulty in selecting. I should not dare 

 say, however, that this would always be the case and a sure test. If you 

 try water on the two forms I think you will find that the baggy ones will 

 be soaked more quickly than the firm ones, disposing of Mr. Roberts' 

 theory. CAKOI.INE G. Son.K, Urookline, Mass.
