THE CANADIAN ENTOMOLOGIST. 95 



except the first and last joints, reddish; anterior and middle tibiae except 

 wide median annulus and their tarsi except the apical joint, yellowish. 

 All the femora have a fringe of strong black hairs on the apical portion 

 of the posterior side. Claws, except their apical half, reddish. Wings 

 long, everywhere tinged with brownish ; veins all brownish. Long, corp., 

 ID mm ; al., 9 mm. 



This species is very closely allied to C. tristis, Loew, but is easily 

 separable from that species by the colour of the antennae and the form of 

 the third joint, which is not at all " subrotundo," as well as by several 

 other characters. 



One specimen [Marin County, California; Haines], in the collec- 

 tion of Cal. Acad, of Science. It was kindly transmitted to me for 

 examination by Mr. Chas. Fuchs, through the courtesy of Mr. H. H. 

 Baer, of the Academy. 



This specimen is the identical one referred to by Mr. C. H. Tyler 

 Townsend, in the Proc. Cal. Acad. Sci., Ser. 2, Vol. IV., 611, under the 

 head of Chilosia^ n. sp. ? 



Allograpta fracta, O. S. Western Diptera, 331, 1877. 



The type of this species, a single male, was captured by Baron Osten 

 Sacken, at Santa Monica, California, February 20, 1876. Since then no 

 record has been made of its capture. In the collection of the University 

 of Nebraska is a single female specimen captured at Los Angeles, Cali- 

 fornia, November, 1887, by Prof. Bruner. It differs in no respect from 

 Osten Sacken's description of the male. The front is yellow laterally and 

 the first segment of the abdomen has the sides as well as the anterior 

 margin yellow. 



It is quite a remarkable fact that of the two specimens of this species 

 known in collections, the latter one was captured in exactly the same 

 locality as the type, though eleven years later. 



Mesogramma parvula, Loew. 



This species has been recorded from Florida and Georgia only. 

 There is a male specimen in the collection of the University, labelled 

 Orizabo, Mex., Jan., '92 ; Prof Bruner. It agrees exactly with the 

 description, except that the black of the second segment of the abdomen 

 is entirely shining and that the third and fourth segments have the black 

 markings very obscure, but like the typical ones in outline. Two other 

 specimens from St. Augustine, Florida, collected by Mr. C. W. Johnson, 

 of Philadelphia,
