120 Eev. T. A. Marshall's monograph of 



tipped with fuscous ; recurrent nervure subinterstitial. M. bimacu- 

 latus, Wesm. 



Var. d. $ . First abdominal segment not whitish at the base ; 

 hind femora and coxae rufous. Taken by Capron. 



The typical form bas the head rufo-testaceous ; face yellowisb ; 

 antennae fuscous, testaceous towards the base ; palpi wbitish ; 

 thorax rufo-testaceous, sides of the prothorax paler ; metatborax 

 rufous, more or less black above, or entirely black ; 1st abdominal 

 segment whitish nearly to the tubercles, afterwards jet-black with 

 a white bind margin; 2d segment either yellow, with 2 lateral 

 black spots varying in size in the 3 ; or in the ? entirely black 

 from the coalescence of the spots, which leave only the fore 

 margin narrowly yellow ; segment 3 (connate with 2) black in the 

 5 , or only the suhiriform articulation is pale ; the following seg- 

 ments are entirely black, or the apex of the abdomen, with the 

 belly, more or less testaceous. Stigma pale, or the inner margin 

 brown, and that colour more or less diffused over the disk. Legs 

 either wholly testaceous, or the femora and tibhe of the hind pair 

 blackened, except at the base ; hind coxae fuscous at the base. 



Head narrower than the thorax ; face flat, quadrate ; eyes and 

 ocelli prominent ; cheeks narrow. Antennae s'etaceous, as long as 

 the body, and nearly equal in both sexes, 29 — 30-jointed in the ? , 

 32-jointed in the 3 . Metathorax short, reticulato-rugulose, the 

 posterior declivity in the J distinct and margined above ; less con- 

 spicuous in the 3 ', somewhat excavated behind. Abdomen hardly 

 longer than the head and thorax, at its broadest part not narrower 

 than the latter ; segment 1 occupying almost \ of the entire 

 length, curved at the end of the petiole, which is smooth; from 

 thence gradually dilated to the apex, and striolated ; the apex less 

 than 4 times wider than the base. Tracheal grooves none. Terebra 

 about i as long as the abdomen ; Wesmael, according to his usual 

 practice, makes it longer, and equal to the whole abdomen. 



Described from a pair, of which the ? is British ; the 

 3 is preserved in one of Wesmael's boxes sent to me 

 from Brussels, and containing all the Braconids of the 

 Musee Koyal, except Wesmael's types. In the same 

 boxes are several specimens of M. bimaculatus, Wesm. ; 

 and I find three more in the Hungarian collection of 

 Dr. Cornelius Chyzer : one of these has the metathorax 

 infuscated ; their cocoons are paler than those of the 

 typically coloured examples. Capron has twice taken 

 the $ at Shiere ; Bignell bred the same sex from 

 Geometra papilionaria, L. Reinhard, in a note appended
