Otherwise similar to, and apparently conspecific with, the two first 

 noted specimens. 



Mixogaster breviventris Kahl. 



1897. Kahl, Kans. Univ. Quart., vi, 137. 



Originally described from Kansas. Before me are two specimens 

 from Yaphank, Long Island, New York, September, (W. T. Davis). 



Callicera johnsoni Hunter. 



1896. Hunter, Can. Ent., xxviii, 87. 



One male from Round Mountain, Texas, differs somewhat from 

 the original description. It wants the opaque marks on the face, 

 cheeks, and abdomen, except that there are faint indications of nar- 

 row, semi-opaque bands on second and third segments. 



Callicera montensis Snow. 



1892. Snow, Kans. Univ. Quart, i, 34 (pi. vii, f. 4). 



One specimen, Grand Canyon, Arizona, 7000 feet alt.. May, (F. M. 

 Jones). This agrees with the original description but the pile of 

 the pleura, pectus, and venter of the abdomen is black. Snow says 

 that the pile of the thorax and abdomen is ''everywhere" golden 

 red. The pile of the eyes in this specimen is blackish brown, not 

 golden. The third antennal joint is at least four times as long as 

 the first and second together. No pale articulations on the tarsi. 



Can this be distinct from montensis? The species was originally 

 described from Colorado, 9000 feet alt., and subsequently reported 

 from New Mexico, at 9500 feet alt. 



Merodon equestris var. validus Verr. 



1822. Merodon validus Meigen, Syst. Beschr., iii, 365. 



1901. Merodon equestris Fab. var. validus Verrall, Brit. Flies, viii, 559. 



One female, San Francisco, California, April, (C. L. Fox), [Cal. 

 Ac. Sci.]. 



CONOPID^. 

 Dalmannia blaisdelli new species. 



Differs from pi da Will, and nigriceps Lw. in having the pilosity 

 black, although on the second and third abdominal segments of the 

 male it is somewhat paler. 



cf . Abdominal segments 2, 3, 4, narrowly yellow at apices, which 

 color extends basally at the middle as a wedge but not attaining the 

 bases of the segments; fifth segment with a medial yellow spot. All
