A small black species with stout legs, and abdomen more or less red. 

 Head transverse, not broader than eyes and somewhat rounded posteriorly ; 

 vertex and face shining, sparsely punctate with long villosity, the latter 

 somewhat deplanate though intumescent beneath antennae ; cheeks broad 

 and buccate, clypeus small and testaceous ; mandibles narrow and, like 

 the palpi, flavidous. Antennae black, filiform and pubescent, of $ slightly 

 attenuate apically ; flagelium consisting of about eighteen joints and 

 extending beyond a[)ex of metathorax ; with basal joint only slightly longer 

 than second and twice longer than broad. Thorax strongly convex with 

 griseous pubescence ; mesonotum very finely and closely punctate with no 

 notauli, the mesopleural sulci strong ; metathorax somewhat shining with 

 complete areae, of which the areola is sub pentagonal, centrally explanate, 

 confluent with the basal area, and apically truncate ; petiolar area discreted 

 and of normal length, apophyses wanting. Scutellum black, sparsely 

 punctate and hardly convex. Abdomen of c^ sub-cylindrical, of 9 slightly 

 rounded centrally ; red, with the first segment always, usually apices of 

 the apical ones and sometimes of all the segments, black or infuscate ; 

 basal segment not contracted basally, parallel sided, sparsely punctate and 

 pubescent, centrally canaliculate throughout, with the prominent spiracles 

 jilaced far l)efore its centre ; following segments somewhat strongly niti- 

 dulous, though with fine flavidous pubescence ; terebra one-third of the 

 abdomen and longer than basal segment. Legs dull testaceous ; coxae 

 black, with front ones infuscate, apices of trochanters flavous, hind femora 

 piceous ; intermediate tibiae curved and hind ones incrassate before the 

 often white base. Wings hyah'ne ; stigma l)road and piceous, radix and 

 tegiilae bright flavous ; areolct not indicated ; its recurrent nervmv strongly 

 sinuate, with fcncstrae very widely separated ; nervellns opposite and not 

 intercepted. Length, 3-5 nun. 



The larva (see figure i) and pupa of this species are, I believe, figured 

 by Ratzeburg in the Act. Ac. L.C. xvi. pi. 9, fig. 1 1 ; but this I have not 

 seen. I^arvae I have noticed, however, are entirely yellowish white, 

 apodous and adipose with no dorsal prolegs at all, the spiracles are
