British Bracorddee. 121 



to Euthe's description (lib. cit., p. 46), records the 

 rearing by himself in two successive years of about 100 

 of M. versicolor from the larvae of Laria L-nigrum, Mull. 

 About a fifth part of them had the recurrent nervure 

 rejected, as in Bignell's specimen, but not in Wesmael's. 

 The second generation was not so highly coloured as the 

 first, corresponding to Euthe's description rather than to 

 that of Wesmael. The latter writer mentions that in 

 June, 1831, he found two caterpillars of Asteroscopus 

 sphinx, Hufn., on a lime-tree near Charleroi, which pro- 

 duced a number of these parasites. They made oval 

 brown cocoons about 2 lines long, irregularly heaped 

 together, and connected by threads of silk. In this 

 case the cocoons were evidently not suspended by a 

 thread; but that of Bignell's specimen, produced singly, 

 is pensile, resembling the cocoons of ictericus, except in 

 being of a darker colour. Van Vollenhoven mentions 

 the capture of this species near the Hague, and Leyden; 

 he has figured one of the specimens. Euthe possessed 

 four males, two females, from the neighbourhood of 

 Berlin.

Black ; palpi whitish ; face, clypeus, mandibles, and sides of the 

 prothorax partly, dull testaceous ; legs, and (in the J ) the base of 

 the antennae, rufo -testaceous ; hind femora and tibiae sometimes 

 infuscated. Wings hyaline ; squamulae testaceous ; nervures 

 fuscescent ; stigma fuscous, its inner angle paler ; recurrent ner- 

 vure subrejected ; 2d cubital areolet not narrowed towards the 

 radius. First abdominal segment elongate, with a linear, slender 

 petiole ; reticulato-rugulose, with arcuate striae on each side of the 

 suddenly dilated condylus ; tracheal grooves obsolete. Terebra 

 curved, as long as the abdomen. $ ? . Length, 2\ — 2!,- ; wings, 

 4—43 ii n . 



Distinguished from the other black species by the elongate 

 petiole, and absence of the tracheal grooves ; also, in the female 

 sex, by the short antennae. Head large, broader than the thorax ; 

 eyes large, prominent ; ocelli small ; face subquadrate, not carinated, 

 sparingly punctured. Antennae of the $ scarcely longer than the
