I cannot at this moment go into the matter again. A male M. 

 snowii (Cresson cotype before me) looks distinct by the white 

 pubescence and very long antennae. In favor of the validity of 

 snoioii is the fact that it does not seem to occur in southern New 

 Mexico, where agilis is so very common." 



Before proceeding to describe another fly as a new species, I 

 have to acknowledge the synonymy of Leria caccahata, as described 

 by me in the preceding papers, as mentioned on pages 301-302, 

 with Leria latens Aid. My name must, therefore, fall, according 

 to the authority of Mr. D. W. Coquillett, of the U. S. National 

 Museum, Washington, D. C, who compared my specimen with de- 

 termined examples of Leria latens of Aldrich, and found it to be 

 identically the same species. My description is in fault regarding 

 the statement of single vibrissa, when in fact an additional one on 

 each side had been broken off. The basal pits showed where these 

 missing bristles had been attached. The record, however, of the 

 insect being new to the Kansas list still holds good, even with a 

 change of name. 



Dolichopu3 jugalis, n. sp. Colorado, Tabernash, 8310 feet, western side of the 

 continental divide of the Rocky Mountains, 89 miles west of Denver; 

 August, 1906. Type: one male specimen. 

 General color shining green. Femora and other joints of legs, except as 

 specified, yellow; cilia of inferior orbit pale; tegulse with black cilia, 

 fourth longitudinal vein deflected, running somewhat forward at 

 the tip. 

 Closely allied to coloradensis Aldrich. from which it differs in the follow- 

 ing particulars: The first antennal joint is yellow only on the under 

 side; face golden yellow, decidedly concave for the greater part above; 

 eyes subopaque black, with comparatively coarse facets; front with a 

 bronze reflection; thorax with a distinct median stripe of shining 

 bronze. Fore coxse yellow, touched with black at base, and trans- 

 versely marked on the front side with a preapical black line bordered 

 by a row of fine black bristles. The two outer bristles are equally long, 

 but inwardly the bristles are much reduced in size, and all are set be- 

 hind the line. Fore tarsi are two- thirds longer than their tibiae; first 

 three joints extremely slender; the second scarcely longer than the 

 first; the third hardly less than two- thirds the length of the second; 

 fourth and fifth together equal in length to the third, black and en- 

 larged to all appearances the same as with coloradensis, unless more 

 symmetrically equal on each side of the axial line. Lamellae of 

 hypopygium more than twice as long as wide, the tips touching pos- 

 terior coxae. Costa of wing slightly thickened at junction of first 

 vein. The posterior margin of seutellum is slightly tinged with yellow. 

 In other respects, the tarsi of middle legs are strongly black from the 

 tip of the first joint; posterior tibiae are infuscated at apex, their tarsi 

 black; the middle and posterior tibiae bear two rows of long, stout 

 black bristles behind, and a few similar bristles are attached in front.
