198 BRITISH ICHNEUMONS. [Lissonota. 



with the basal segment about two and a half times longer than apically 

 broad, finely and transversely aciculate with its apical fourth part bright 

 red ; second to fourth segments entirely bright red ; second a little longer 

 than broad ; third a little broader than long, glabrous with obsolete acicu- 

 lation ; terebra about as long as, or slightly longer than, the abdomen. 

 Legs red, with the anterior trochanters infuscate and the hind ones black ; 

 apices of the hind tibiae and their tarsi subinfuscate. Wings with the 

 areolet triangular, narrow and subsessile ; nervellus opposite and inter- 

 cepting at the lower fourth. Length, 6J mm. 



Bridgman says this species is similar to L. hellator and L. van'pcs, but 

 is stouter and more glabrous, especially as regards the abdomen, which is 

 differently sculptured. 



I possess two 9 9 which obviously belong to this species, since they 

 agree in every way with the above description of Bridgman, excepting in 

 having the mandibles and palpi also testaceous, and in one all the coxae 

 red while in the other they are nigrescent-badious. The antennae are 

 three-quarters the length of the body, immaculate with their apices obtuse ; 

 the mesonotum is dull, closely and confluently punctate ; the metathorax 

 scabriculous with obsolete indications of an areola and the basally strong 

 petiolar area much smoother ; the basal segment is remarkable : — black, 

 gently arcuate and very finely reticulate to a strong and aciculate trans- 

 verse impression at its apical third or fourth, whence it becomes deplanate, 

 subglabrous, nitidulous and bright red ; the second segment is certainly 

 not broader than long ; the terebra is distinctly reflexed ; the stigma pale 

 piceous and the recurrent nervure is emitted from the centre of the 

 areolet. 



It has probably been mixed, like L, Icucogona, with L. bcUator but is 

 easily recognized by its immaculate red tibiae and three central segments, 

 short terebra and entirely black vertex. The sparsely pilose cheeks and 

 sessile areolet will distinguish it from L. Bletcheri. 



Schmiedeknecht suggests the synonymy of Szepligeti's $ Z. vaga from 

 Hungary with this species. 



Only one female bred, without locality, from Botjs asmalis was known 

 to Bridgman ; my two females, mentioned above, were both taken on the 

 flowers oi Aiigelica sylvestiis in August, one on the 8th in 1901 at Matley 

 Bog in the New Forest and the other at noon on the 29th at INIonks' 

 Soham in 1907 ; it is, however, very probably not uncommon with us.
