100 THE ENTOMOLOGIST. 



INTRODUCTORY PAPERS ON ICHNEUMONID^. 

 By John B. Bridgman and Edward A. Fitch. 

 No. v.— OPHIONIDiE (continued), 



Charops, Holmgr. 



Middle of abdomen red ; front legs reddish, base black. 



1. clecipiens, 5 lines. 



This species is much like Campoplex pugillator, but with no 

 areolet in the front wings. It appears to be rare. According to 

 Giraucl it is parasitic on Zygcsna JilipendulcB, and has been bred 

 by Perris from Botys lupulinalis. 



Since the publication of the generic table of the Ophionidse, 

 another of Forster's genera has been detected in this country. 

 This will necessitate a slight alteration. In Section II., Division I., 

 Subdivision 1, after B. must be added : — 



I Eyes hairy. 



! Wings without an areolet ; post-petiole with a transverse depression. 



Thymaris. 

 !! Wings with an areolet. - - - - - Cymodusa. 



Thymaris, Foist. 



2nd and 3rd segments of abdomen red-banded, 4th obscurely so ; front 

 legs pale red, base black, hind legs black, middle of tibiae red. 



fasciatus, 3^ lines. 



This vei-y distinct subdivision of Cymodusa has been added 

 on the strength of a male specimen captured in Norfolk by 

 Mr. Thouless, in 1884. Forster, as was so often his custom, 

 described no species of the genus he created. Brischke described 

 T. pulchricornis in the Danzig. 'Schriften' (vol. v., pt. 1, p. 38), 

 but that is very distinct from the one now under consideration. 



Cymodusa, Holmgr. 



A. Abdomen black (male). 



Front legs and apex of hind trochanters yellow, middle of hind tibiae 

 yellowish red. ------ fiavipes, 3 lines. 



B. Middle of abdomen more or less red; legs red, coxae and base of 



trochanters black, tarsi fuscous ; aculeus about as long as the 

 1st segment (males and females).
