blackish about to the distal end of the small basal cells. 

 The third vein is spinose about half way to the small cross-vein. 



The abdomen is metallic purple in all the specimens before 

 me, but this is in all probability subject to the usual variations 

 of the Calliphorina?. The first segment and a fascia on the 

 caudal borders of the second and third segments are much 

 darker, almost black. With a very oblique light, the abdomen 

 appears almost everywhere whitish pollinose. There are no 

 bristles on the first segment. The second and third segments 

 have each a marginal row of slender appressed bristles, which 

 are larger toward the sides of the segments. The fourth segment 

 has both marginal and discal bristles. 



The legs vary in color from brown to black. Their bristles 

 are as in C. seginentan'a. 



For the excellent drawings of the wings which accompany 

 this and the following papers, I am indebted to my friend. Dr. 

 Emma H. Wheeler. 



MUSCIN^ MUSCIFORMES. 



Morellia bipuncta Fabr. 



Seven males and two females ; Chapada ; no dates. 



Agrees with Wiedemann's description, to which I wish to add 

 the following : 



The color of the face varies in different individuals, and, ac- 

 cording to the incidence of light, from yellow through brown to 

 black. The bucca and vibrissal ridge are wholly polished. The 

 gena is polished, except for a small white pollinose patch near 

 its dorsal third. The ventral half or so of the posterior orbit is 

 white pollinose*; in the female the dorsal half and the vertex is 

 metallic green ; in the male the posterior orbit, owing to the 

 greater occipital extension of the eye, only exists along the 

 ventral half of the occipital border of the eye. The antenna^ 

 in most of these specimens are brownish yellow rather than 

 brownish red, and the third joint is more or less pollinose ; 

 the arista is only sparsely plumose and has a yellow rachis ; 

 the third antennal joint is hardly more than twice as long as 

 the second. While many male Muscina^ have an area of en- 

 larged facets on the cephalic surface of the eye, this species 

 stands out prominently as having an area with facets very much 

 larger than in any other species known to me, some of them 

 measuring as much as one-twentieth of a millimeter.
