Catalogue of British. Ichiieumonidce. 163 



This species Mr. Marshall has placed in his Catalogue 

 as a synonym of L. hellator, but Mr. Billups's specimens 

 differs from L. hellator in having the j)unctures on the 

 back of the mesothorax rather larger and more scattered, 

 aculeus is shorter, face and thorax entirely black.

In Marshall's Catalogue this insect is included as a 

 synonym of L. irrisoria. I think this must be a mistake ; 

 the description of the two insects are so very different. 

 I have taken six males, and the only variation seems to 

 be in the two central pale lines on the face, which are 

 sometimes absent. I am inclined to think the L. lepto- 

 gaster, Holm., is this latter variety. I once sent this 

 insect to Mr. Marshall, and he returned it as a Mesoleptus 

 which he could not name ; the narrow 1st abdominal 

 segment certainly gives it at first sight a right to a place 

 in that genus. 



Lissonota femorata, Holm. 



Holm., Mon. Pimp. Suec. 55, 20, ? . 



I have taken three females in this neighbourhood which 

 agree exactly with Holmgren's description. 



Lissonota Fletcheri, n. s. 



Niger, abdominis medio, femoribus, tibiis tarsisque 

 rufis ; abdominis primo segmento subaciculato. 



Head transverse, slightly narrowed behind the ej'es ; 

 antennae of male rather shorter than the body, of female 

 rather more than half the length of the body ; 1st joint 

 of flagellum rather longer than the 2nd, about three 

 times as long as wide ; cheeks slightly descending below 

 the base of the mandibles ; lower part of face and 

 cheeks covered with fine dense white pubescence ; face 

 transverse ; head, thorax, and abdomen finely and 

 densely punctured ; interstices reticulate ; 1st segment of 

 abdomen about as long as the hind coxse, gradually 

 tapering from base to apex, this latter about twice as 

 wide as the base ; apical portion distinctly but finely 

 aciculate ; 2nd segment quadrate ; 3rd and following 

 ones transverse ; aculeus as long as the abdomen.
