2. Procladius scapularis Loew 



Tanypus scapularis Loew, Berl. Ent. Zeitschr., Vol. 10, 1866, p. 2. 



Male. — Black, subopaque. Head white behind and above eyes ; 

 antenna: black, the plumes on the basal two-thirds pale brown, on 

 apical third almost black, apical joint with white hair. Pronotum, lat- 

 eral margins of mesonolum anterior to wing-base, and almost the 

 whole central and anterior portion of pleura: creamy white; scutellum 

 and postnotum black. Abdomen black with three yellowish white 

 bands, a broad one at base, a much narrower one at middle, and the 

 third on the apical half of the sixth segment; apical portions of hypo- 

 pygium white. Legs black; coxae at apices, trochanters and bases of 

 femora, tibiae except bases and apices, and the basal two-thirds of 

 first tarsal joint of all legs wdiitish yellow\ Wings clear, cross vein 

 blackened. Halteres pale yellow. 



Antenna slightly longer than head and thorax together, basal joint 

 much swollen, plumes long and dense. Mesonotum with short discal 

 hairs, those on lateral margins in front of wing-base most distinct; 

 scutellar hairs not strong. Abdomen with numerous short surface 

 hairs; hypopygium as in Figure 8, Plate XXVIII. Legs slender; fore 

 tarsus without long hairs, its basal joint two thirds as long as fore 

 tibia, and distinctly longer than the remaining joints combined; fourth 

 tarsal joint on all legs obcordate. Costa reaching almost to apex of 

 wing ; radius reaching well round the curve at apex ; petiole of cubitus 

 barely longer than its own width. 



Female. — Similar to male in coloration, except that the head is 

 almost entirely yellow, and the antennal hairs are unicolorous brown; 

 the abdomen is unicolorous black except the base of venter, which is 

 yellowish; the fore legs are entirely black except the bases of the 

 femora, and the yellow tibial bands are much narrower. 



The antenna is very much shorter than the thorax, the basal joint 

 slightly swollen and the apical joint very slightly so, the surface hairs 

 are very short. Thorax as in male. Abdomen stout. Leg propor- 

 tions as in male, and also the wing venation. 



Length, 3.5-4 mm. 



Localities, Savanna, 111., Julv 20, 1892, and Havana, 111., August 

 8, 1896. All females. 



The only males I have seen belong to the collection of the Bureau 

 of Biological Survey, and were taken at Washington, D. C, and on 

 Plummer's Island, Aid., by W. L. McAtee. 



The species was originally described from W^ashington, D. C, and 

 has been subsequently recorded from New Jersey by Johannsen. 



The early stages are unknown to me.
