Catalofine of British Ichneumonidce. 361 



1st joint of tarsi, yellowish red. Wings smoky ; stigma fuscous ; 

 tegulae yellowish, piceous at the base. 



The male differs from the female in having the face and antennae 

 black, hmd legs entirely black, and tegulae piceous. Abdomen : 2nd, 

 3rd, and 4th segments red ; 2ud sometimes with a dusky spot on 

 the back. 



Male and female. Length about 9 mm. 



Norwich, end of July, 1879. 



I believe these are the two sexes of the same insect, 

 although the colour of the face is the reverse of what is 

 generally the case ; usually the male has the yellow face, 

 and the female black. 



Pheudus, n. g. 

 Caput supra subquadratum. Clypcus rotundatus, discretus. 

 Antennre fere corporis dimidio lougitudine, filiformes. Ocelli 

 oblougi. Thorax robustus gibbulus, scutello vix elevato, meta- 

 thorace altitudine multo breviore, areis completis, spiraculia 

 minutis circularibus. Abdomen petiolatum, ovatum, glabrum. 

 Segmenta 2 — 7 transversalia. Segmentum primum fere equilatura, 

 curvatum, latitudine triple longiore, aculeo segmento primo dimidio 

 breviore. Pedes mediocres, femoribus anticis validiusculis, ungu- 

 lis tarsorum pectiuatis. Alse areola instructse, 5-zona. 



This insect is very peculiar. I can find nothing 

 described like it. In general appearance it is not unlike a 

 small PJiyfiadeuon, but the pectinated claws and the 

 antennffi clearly take it from this genus ; the pectination 

 of the claws is like that of the genus Pcmiscus, whilst 

 the antennae are like those of Thersilochus, and, viewed 

 sideways, it resembles this latter, but the shape of the 

 head, form of the areolet of the wings, as well as the 

 arrangement of the costae on the metathorax, will 

 prevent its being placed in this genus. 



Thomson thinks its proper place is in the TrypJionidce, 

 and should come under his Ctenopelmidce ; I am indebted 

 to him for the suggested names.
