226 Mr. Edward Saunders on 



especially the 8th 9th and 10th, thorax clothed with very pale 

 ochreous hairs above, with white hairs beneath ; mesonotura in- 

 cluding the scutellum shining, remotely punctured, wings hyaline, 

 nervures piceous, 2nd recurrent received in the 2nd submarginal 

 cell, propodeal area depressed dull and finely rugose, bounded 

 posteriorly by a shining curved somewhat raised line, abdomen 

 strongly and remotely punctured and clothed with scattered pale 

 hairs, the segments much raised across the disc, apical impressions 

 very deep, pale and impunctate and crossed by a fringe of fine hairs 

 which grow on the apex of the raised portion of the segments, legs 

 with pale calcaria and clothed with white hairs. 



5 differs from the ^ in the ordinary sexual characters, also in 

 being more finely punctured. The antennse are testaceous beneath 

 and at the apex, and the joints of the flagellum are very short and 

 transverse, vertex of the head and mesonotum rather closely but 

 irregularly punctured, in this respect very diff"erent from vulgaris, 

 propodeum like that of the ^, puncturation of the abdomen less 

 strong than in the (J but well marked, that of the basal segment 

 stronger and more remote than of the others, impressions very wide 

 and pale i:)iceous, legs more or less piceous varying very much in 

 depth of colour.

This specimen, which bears a label in Herr Friese's 

 handwriting siviilis (?) is very like the above, but diifers 

 in the shallower abdominal impressions and the more 

 polished mesonotum wliich is scarcely punctured.
