ERTTHROTHEKON1A. PIMPLA. 151 



iridescent, with a slight inf umate-violaceous reflection ; tegulas 

 internally flavous, stigma testaceous and iiervures black. 



Length 12-14 ruillim. 



CEYLON : Kandy, vii. and ix. (E. E. Green, 0. S. Wickivar}. 



No mention is made of the disposition of the wing-nervures 

 in the above description, but from the figure (I. c.) it seems 

 evident that the areolet is remarkably transverse and fully 

 twice as broad as high, emitting the recurrent nervure from 

 slightly before its apex ; the radius is bisinuate, above the areolet 

 and a little before its apex ; the basal nervure is poorly figured ; 

 nor does it appear clear whether the nervellus is emitted at, or 

 distinctly a little above, the centre of the obviously postfurcal 

 first recurrent of the hind wing ; the figure given by Cameron is 

 that of the c? . In my females all these points are correct, the 

 basal nervure is continuous through the median, and the nervellus 

 is intercepted very distinctly above its centre. 



Superficially this species has much the facies of a pale EcWiro- 

 morplia.

 GENOTYPE, Ichneumon instigator, F. 



Head transverse, short and broad, somewhat narrowed behind 

 the usually slightly emarginate eyes ; frons subim pressed, shining, 

 centrally a little concave, with the scrobes large ; clypeus basally 

 distinctly discrete, towards the apex strongly depressed, and not 

 emarginate apically ; labrum but slightly exserted ; mandibles 

 apically attenuate, with the teeth of equal length. Antennae 

 filiform and in $ very slender ; scape strongly excised exter- 

 nally and in J often pale beneath. Thorax stout and convex, 

 often pilose and shining ; notauli usually obsolete ; metathoracic 

 areae never entire, usually the lateral alone traceable ; spiracles 

 not circular. Scutellum not strongly convex ; often pale. Abdo- 

 men broadly sessile and usually wider in the middle ; first segment 

 excavate at the base and, at least there, carinate, with the spiracles 

 before the centre ; remaining segments usually distinctly broader 

 than long, especially in the $ , with the surface strongly punctate, 

 distinctly uneven, laterally tuberculate, transversely impressed 

 before the subelevated apices ; two apical ventral segments of $ 

 divided for the passage of the terebra, which is always exserted, 

 though never longer than the abdomen. Legs not unusually short 

 or stout ; tarsal claws simple, neither lobate nor pectinate. 

 Wings with the areolet complete and subtriangular ; nervellus 

 always intercepting the first recurrent of the lower wing above 

 its centre. 



Range. Both hemispheres.
