Some New Species of Hymenoptera. 333 



the anterior tibiae and tarsi and the four hinder legs, except their 

 coxae, bright red ; wings hyaline to near the base of the stigma, dark 

 fuscous, slightly tinged with violaceous beyond the stigma and 

 nervures black. $ . 



Length 6 mm. 



The third joint of the antennae is almost twice the length of the 

 second, i.e., the pedicle; its base is pale rufous. Head above the 

 antennae distinctly, uniformly, but not closely, punctured ; a stout 

 keel between and below the antennae ; the space bordering it opaque, 

 impunctate ; there is a smooth line below the ocelli ; which are 

 arranged thus '* ; the anterior separated from the posterior by a 

 distinctly greater distance than these are from each other ; they are 

 separated from each other by about one-fourth the distance they are 

 from the eyes. Mesonotum sparsely punctured, the apex almost 

 impunctate ; the furrows indicated only close to the apex. Scutel- 

 lum very smooth and shining. Base of metanotum opaque, 

 aJutaceous, the centre almost obscurely finely obliquely striated ; 

 the apical slope smooth and shining, as are also the metapleurse, 

 except at the base where there are a few striae. 



Head slightly wider than the thorax, transverse behind, as wide 

 there as the length of the eyes and temples united ; the latter slightly 

 shorter than the eyes. Prothorax short ; mesonotum wider than 

 long. Scutellum large, wider than long, narrowed behind ; bounded 

 by a wide shallow furrow at the base, the furrow widened into foveae 

 at the outer edges. The metanotum is not so long as the mesonotum 

 and the scutellum united. The first abdominal segment is furrowed 

 down the middle on the basal half ; the third abdominal segment is 

 longer than any of the others. Sides of head and thorax covered 

 sparsely with white pubescence. Antennal scape as long as the 

 following two joints united ; the third joint is shortly but distinctly 

 longer than the fourth.
