138 FAMILY EVANIIDyE. 



area. The groove for the reception of the middle femora is not 

 very deep. The sides of the propodeum are not peculiarly sculp- 

 tured, as in Hyptia. The metanotuni is sunk deeply between abrupt 

 walls formed by ttie scutellum and propodeum (Fig. 62). The fur- 

 cula forming the posterior border of the mesaventer is of great 

 importance and may be with parallel or divergent lobes or tynes 

 (Figs. 64 and 65). 



The abdomen of the female is the shape of an isosceles triangle, 

 the pygidium being produced into a projection which contains the 

 ovipositor (Fig. 18). In the male the abdomen is oval. 



The posterior legs are long (Fig. 60), and always without spines. 

 The proportion of the longer tibial spur to the metatarsus is of 

 importance, as also that of the metatarsus to joints two to four 

 together. The shape of the tooth on the tarsal claw and its size 

 and angle are of importance (Figs. 44 and 45). 



The wings are as shown in Figs. 76 and 77. 



The genus is the most generalized of the subfamily. It is dis- 

 tributed throughout the world, except in the Australian region, 

 where one, perhaps accidental, species is found, and three otliers 

 just over the border in the Island of Lombok. But Evania appendt- 

 gaster, believed to be originallv European, has been introduced into 

 every country. 



TABLE TO THE NORTH AMERICAN SPECIES OF EVANIA. 

 1. Face with only a few small punctures; tarsal claws with two rays placed so as 

 to form an acute angle, the inner one shorter {Fig. 44); antenna; 

 inserted close together in a broad shallow basin, wiib an abrupt but 



scarcely ridged front margin appf iidigaster Linnaeus. 



Face coarsely longitudinally striate ; tarsal claw bearing a tooth within nearly 

 at right angles to the outer ray (Fig. 45) ; autennte situated rather far 

 apart in a deep and well-marked basin, the anterior and lateral mar- 

 gins of which are limited by a distinct carina, with a sharp angle in 

 the centre below the antenna; urbiina n. sp.
