178 FAMILY EVANIID^. 



Evaniella canieroiii n. sp. 



Black; pronotum and mesonotum red; anterior legs, excejit ilie apex of the 

 trochanters externally, which are lirown, and base of the middle and posterior 

 trochanters, yellow. Sparingly pubescent. Head from above transverse-quad- 

 rate; eyes prominent; posterior ocelli nearer the compound eyes than to each 

 other. From the side the temples are narrow, little widened below; tlie eyes 

 very large ; the malar space quite small. From in front the face is nearly round, 

 the inner margins of the compound eyes almost straight, slightly diverging 

 below; the sculpture of the face almost obscured by vestiture, in a favorable 

 light seen to be finely and irregularly but not very roughly punctate; a long 

 distinct carina extends on each side froru the outer margin of the clypeus 

 upward to below a point midway between the anlenna* and the margin of the 

 eyes; forehead with fine close punctures, in front of the compound eyes these 

 are replaced by larger more sepai'ated round punctures, which continue on the 

 vertex, temples and cheeks; forehead with a distinct median carina. Antennaj 

 filiform; scape over four times as long as the pedicel, five-eighths as long as 

 joints 3+4; the pedicel one-third as long as joint 3. the latter thiee-fourths as 

 long as joint 4. 



Pronotum scarcely notched above by the mesonotum ; humeral angles squarel.v 

 cut; mesonotum anteriorly and the side of the scutellum with a few scattered 

 round punctures, otherwise smooth; anterior, parapsidal and lateral grooves 

 very distinct; mesopleurse punctured, with a small smooth and polished area 

 above; furcula with short indistinct parallel tynes; propodeum reticulate; the 

 reticulations produced into oblique bars over a short area on the sides. Poste- 

 rior tibial spur two-thirds as long as the metatarsus. 



Petiole impunctate; abdomen broadly elliptical ; the apical segments pubescent.

ZEUXEVA]VIA Kieffer. 

 1902. Zeuxevania Kieffer, Gen. Insec, 2, p. 4. 



Type. — Evania dinarica Schletterer. 



In this genus (see Figs. 80 and 81) the cell M4 is elongate and 

 situated nearer to the base of the wing than in Evania, the veins 

 nicu and part of the base of M form its anterior boundary, and 

 join together to form a regular arc. At the same time r-m and 

 M3+4 become interstitial, appearing as a single almost longitudinal 

 vein, instead of r-m joining M a short distance before the separa- 

 tion of Mil 2 and M3 j 4, as is the case in Evania. It is evident that 

 the modilication has proceded from the type that we liave in Evania 

 by the base of the free part of M migrating backward along R to a 

 distance almost halfway between the base of the wing and the 

 stigma, and then in some of the species becoming lost, but in a new 

 species that I have here to describe remaining as a faint vein (Fig. 

 80).* The mouthparts are shown in Fig. 32. 



Occurs in tlie Palearctic, Etliiopian and Oriental regions. Six 

 species in all. 



* This has been recently described as I'drevania, see addenda.
