name. As an example of the frequent use of the same specific 

 name in different genera, in other branches of Natural History, I 

 may mention an instance in the latest standard work on British 

 Fishes (Dr. Day's ' Fishes of Great Britain and Ireland ') in 

 which the trivial name vulgaris is indexed to no less than fifty- 

 two genera, and this is by no means an isolated case.

INTRODUCTORY PAPERS ON ICHNEUMONID^. 

 By John B. Bridgman and Edwakd A. Fitch. 

 No. v.— OPHIONID^ {conti7iued), 



Opheltes, Holmgr. 



Fulvous ; part of head and thorax and apex of abdomen black. 



1. glaucopterus, 7 — 9 lines. 



This fine species, of which the male is almost unknown 

 (Entom. xii. 55), is not common in Britain. It is figured by 

 Panzer (Schsef. Ic, pi. 82, fig. 3). It is a sawfly parasite, having 

 been bred from the three species of Cimhex, thus being a con- 

 spicuous exception to the general lepidopterous parasitism of the 

 Ophionidse. Hartig, Drewsen, Reissig, Giraud and Brischke 

 bred it from Cimhex femorata (variabilis), Giraud from C. hume- 

 ralis [axillaris), and Siebold from C. connata ; the latter from 

 eggs deposited by a virgin mother (Ent. Nach., x. 95). 



Paniscus, Schr. 



Almost entirely fulvous. 



A. 1st segment of the abdomen hardly shorter than the hind coxae and 



trochanters ; aculeus of female about as long as tbe 1st segment 

 (males and females).

b. Tarsi and tibise of tbe same colour. 



* Sides of head behind the eyes, seen from above, parallel, 

 f Larger ; elevated line before apex of metathorax. 



1. cephalotes, 6 — 9| lines.

fuscicornis, 3—5 lines. 

 ** Sides of head behind the eyes slanting. - 3. testaceus, 4^ — 9 lines. 



B. Ist segment of abdomen shorter than the hind coxae and tro- 



chanters ; aculeus of female hardly exserted ; hind tarsi paler than 

 tibiae (male and female). - - - 2. virgatus, 3 — 5 lines.
