Genus ELEPHANTOMYIA Osten Sacken. 

 1859. Elephantomyia Osten Sacken, Proc. Acad. Nat. Sci. Phila., p. 220. 



The genus Elephantomyia has long been referred to the tribe 



Antochini and later to the Eriopterini. The presence of distinct 



tibial spm-s would indicate that this genus, hke Atarha, is an aberrant 



hexatomine form. 



Elephantomyia supemvuneraria sp. n. 



General coloration dark brown; thoracic pleura gray pruinose 

 with two narrow dark brown longitudinal stripes; legs black; wings 

 subhyahne with a heavy l)rown pattern; a supernumerary cross- 

 vein near the outer end of cell R2. 



Male.— Length, (excluding rostrum) about 5.4 mm.; wing 5.8 mm.; 

 rostrum about 3.9 mm. 



Rostrum long and slender, dark brown. Antennae dark brown; 

 verticils elongate. Head gray. Mesonotum dark brown. Pleura 

 pale brown, sparsely pruinose, with two narrow dark .brown longi- 

 tudinal stripes, the dorsal stripe beginning at the cervical sclerites, 

 extending beneath the wing-root; the ventral stripe begins on the 

 mesosternum before the middle coxa, passing beneath the halter to 

 the base of the abdomen. Halteres yellow, the knobs infuscated. 

 Legs with the fore and middle coxae infuscated; posterior coxae 

 less darkened; trochanters obscure yellow, the margin with a brown 

 spot; remainder of the legs black, the bases of the femora narrowly 

 pale; the joint between the femur and tibia is narrowly and indis- 

 tinctly pale. Wings subhyaline with a heavy and conspicuous 

 brown pattern, distributed as follows: At arculus; a large area at 

 the origin of Rs, extending caudad to vein M; a small spot at the tip 

 of *Sci; a conspicuous seam at the stigma, continued along the cord 

 to the fork of M; rounded spots at the tips of veins Ri and R2, the 

 latter extending onto the supernumerary crossvein in cell R-; wing- 

 tip infumed; brownish seams along the outer end of cell 1st M2 and 

 the ])asal deflection of Cui; veins light brown, slightly darker in the 

 infuscated areas. Venation: »Sc long, *Sci extending to about oppo- 

 site four-fifths the long Rs; Rs strongly arcuated at origin; Ri 

 very short, a little less than m; a supernumerary crossvein in cell Ri 

 near its outer end, the tip of vein Ri beyond it pale and without 

 rnacrotrichiae; cell 1st Mi large, rectangular, about as long as as a 

 little shorter than vein il/1 + 2 beyond it; basal deflection of Cui at 

 or beyond midlength of cell 1st M2, a little longer than Cu2. Abdo- 

 men dark brown, the base of the hypopygium a little brighter. 

 Male hypopygium with the two pleural appendages subequal in
