376 Professor Williston on the 



Epiplatea. 



Loew, Berl. Ent. Zeit., 1867, 324. 



1. Epiplatea amahilis, n. sp. 



$ . Front moderately broad, slightly narrower above, opaque 

 yellowish-red, with short black hairs. Face shining translucent 

 reddish-yellow ; gently excavated under each antenna; nearly 

 vertical and straight in profile. Frontal, facial and occipital orbits 

 narrowly silvery- white. The clypeus forms a narrow, horse-shoe 

 shaped body, not projecting in profile. Antennae reddish-yellow ; 

 third joint elongate oval, not reaching quite to the lower margin of 

 the face ; arista black, bare. Proboscis stout ; palpi slender, 

 yellowish, except at the base. Mesonotum uniformly yellowish- 

 red (about the same colour as the front) ; scutellum somewhat 

 brownish, with four bristles. Pleuras shining, more brownish, in 

 the middle below brown. The short hair of the mesonotum and 

 the bristles are black. Abdomen wholly deep shining black, with 

 short black hair ; ovipositor but little longer than the last 

 abdominal segment, black. Legs deep brown, the knees and 

 tarsi more yellowish ; middle tibias with a stout spur ; front 

 femora with some bristles below. Wings nearly hyaline ; the 

 costal and subcostal cells, reaching back through the beginning of 

 the submarginal cell to the fourth vein, a band beginning at the 

 outer part of the first vein and reaching over the anterior cross- 

 vein, an elongate spot of about the same width covering the pos- 

 terior cross-vein, and the apex of the wing, save a rounded interval 

 at the very tip, brown ; third and fourth veins somewhat con- 

 vergent at the tip ; anal cell rounded distally, not at all drawn out 

 into a point. Length 4^-5 mm. 



This species, it will be seen, does not agree in all its 

 details with the characters given by Loew for the genus, 

 but the discrepancies are trivial. In some specimens the 

 brown spots of the wings are narrower, and that at the 

 tip might be called an incomplete band. Four speci- 

 mens.
