134 SPOUA ZEYLANICA. 



large central area extending from the base to the apex of the metano- 

 tum, the base being narrowed owing to the basal arese. There is a 

 curved black line on the occiput. 



A variable species as regards the size of the black markings. The 

 scutellum may have no black mark ; the size of the black lines on the 

 legs varies, that on the hind femora may be cleft, wholly or in part, 

 the pleurae may be marked with black, and, as is the case with many 

 Pimplides, there is a considerable variation in size. 



Erythrotheronia, gen. no v. 



Median segment areolated, not toothed ; the spiracles longer 

 than wide. Scutellum raised, stoutly keeled laterally to near the 

 apex. Abdomen smooth, without furrows. Eyes incised, but not 

 deeply on the inner side ; malar space almost absent. Last joint of 

 antennae shorter than the preceding two united. Areolet oblique, 

 5-angled ; the transverse median nervure interstitial. Transverse 

 median nervure in hind wings broken distinctly above the middle. 

 Temples moderately large, obliquely narrowed. Legs stout ; the 

 claws large, edentate. 



The type of this genus looks like a red Xanthopimpla or Theronia . 

 In Dr. Ashmead's system it comes near to the New Zealand 

 genus Allotheronia, from which it differs in the regularly areolated, 

 not dentate median segment. Theronia and Neotheronia differ, 

 inter alia, in having pectinated claws.

 lines on the mesonotum, inner side of tegulae, the edges of mesonotum 

 at the base, scutellar keels, apex of scutellum, post-scutellum, apical 

 slope of metanotum, pleurae except above and the apices of the 

 abdominal segments, yellow. Legs ferruginous, the four anterior 

 coxae and trochanters yellow, as are also the hinder trochanters.

Antennae black, the scape yellow, the Hagellum brownish beneath. 

 Face sparsely, but distinctly punctured, the sides raised. Thorax 

 and abdomen smooth, shining, impunctate ; the mesonotum thickly 

 covered with fuscous pubescence. On the base of the metanotum 

 are tive large arctu, a large central, twice longer than wide, with two
