 longer than wide, oval, but a little pointed at tip; fore tarsi plain, 

 fii-st three joints yellow, last two black (sometimes only the firet) and

 broader than fourth; middle tibiae with three bristles below, one pair

No. 118. DOLICHOPUS JUGALIS Tucker. 



Dolichopus jugalis Tucker, Trans. Kansas Acad, of Sci., vol. 23, 1911, p. 160. 



The following is a copy of the original description: 



Colorado, Tabernash, 8,310 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 the legs except as speci- 

 fied, yellow; cilia of inferior orbit pale; tegulae with lilack cilia, fourth vein de- 

 flected, running somewhat forward at tip. 



Closely allied to coloradensis Aldrich, from which it differs in the following par- 

 ticulars: The first joint of the antennae is yellow only on the under side; face sub- 

 opaque black, with comparatively coatse facets; front with a bronze reflection; 

 thorax with a distinct median stripe of bronze. Fore coxae yellow, touched with 

 Ijlack at base, and transversely 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 behind the line. Fore 

 tarsi two-thirds longer than their tiljiae; first three joints extremely slender; the second 

 scarcely longer than the first, the third less than two-thirds the length of the second, 

 fourth and fifth together equal in length to the third, black and enlarged to all ap- 

 pearances the same as with coloradensis, unless more symmetrically equal on each 

 side of the axial line. LameHae of the hypopygium more than twice as long as wide, 

 the tips touching posterior coxae. Costa of wing slightly thickened at junction of 

 first vein. The posterior margin of scutellum is slightly tinged with yellow. In 

 other respects, the tarsi of middle legs are strongly black from the tip of the first joint;
