base of the coxse; evenly reticulate, coarsely so behind the inser- 

 tion of the abdomen, finely so at the base. Pleurae punctate- 

 reticulate, the mesopleura with a long smooth space above that 

 extends downward anteriorly. Metasternal process long and very 

 narrow medially, its tines well-developed, widely divergent, and 

 but slightly curved. Legs slender; hind coxae microscopically 

 transverse-reticulate; hind femora simple; hind leg not over twice 

 as long as the body; longer spur of hind tibia half the length of 

 the metatarsus. Petiole of abdomen coarsely obliquely striate 

 except near the base. Wings with the basal vein lying closer than 

 usual to the subcostal vein; cubitus arising very close to the junc- 

 tion of the basal and subcostal veins; nervulus interstitial with 

 basal vein; radial vein meeting the subcosta at an acute angle; 

 cubitus and subdiscoideus wanting beyond the cells. Hindwing 

 with seven frenulum hooks. 



This species is somewhat similar to E. verrucosiyes KiefiF. and 

 might possibly be the male of that species which is known from 

 the female only. However, the sculpture of the temples, scutel- 

 lum, propodeum and petiole is entirely different and the thorax is 

 nearly twice as long. From E. cristatifrons Kieff. also known from 

 the female, it differs by the absence of the carina on the vertex 

 and the pectinate process between the antennae, by the sculpture 

 of the petiole, and form of thorax. From E. divergens Kohl it is 

 evidently distinct, although Kohl's description is very incomplete. 

 The cheeks are shorter and the basal joints of the antennae are 

 much longer, and the color is different. The thorax is very much 

 more elongate than in any other Evania that I have seen and the 

 antennae are more slender. The thorax is fully twice as long as 

 high and the propodeum slopes gradually from base to tip, whereas, 

 it usually bends abruptly with an almost vertical posterior face.
