oval pupa of dark brown silk, 12 mm. long by 6 mm. broad, 

 is formed within the skin of the host several days subsequent 

 to its death. One larva spun up in this way on February 13 

 and the adult emerged March 15, a period of thirty-one days 

 being required for the transformation.

Fulvous, head in part and scutellunt flavous, apical half of antennce 

 fuscous; mesonotum with three carince ; metanotutn with two lateral 

 subtriangular fuscous spots; the head roundly narrowed behind the eyes ; 

 ocelli large, close to tops of the eyes. 



Length, 23-25 mm. ; antennae, 27 mm. 



Fulvous ; head varied with flavous ; face narrow ; cheeks narrow, 

 flattened ; face and clypeus together twice as long as broad ; ocelli 

 large, well separated, close to tops of eyes, arranged as an isosceles 

 triangle ; apical two-fifths of antennae fuscous, especially above. 



Mesonotum with two longitudinal furrows converging on the scu- 

 tellum, dividing it into three lobes : keels more or less distinct on the 

 lateral lobes ; scutellum flavous, with lateral keels connecting it with 

 the mesothorax in front with an inconstant rounded lateral fuscous 

 spot at the base ; metathorax short, with anterior transverse carina, 

 sometimes stronger in the middle, running at the sides into a small 

 protuberance ; shallowly excavated behind, with irregular arcuate 

 wrinkles and a varying bronze reflection most constant below, as well 

 as an irregular, somewhat ragged lateral fuscous spot. 



Wings with the ba^e of the radial vein somewhat " drawn out." 



This species resembles E. {Allocamptus) undulatus Grav. I 

 have not seen a specimen, but give a free translation of the un- 

 fortunately incomplete original description from the German. 



Type. — Collection of Dr. Hans Brauns. 



Distribution. — Santos, Brazil. 



This species is evidently semitropical, as the type was taken 

 at Santos, Brazil, just south of the Tropic of Capricorn.
