232 BRITISH ICHNEUMONS. [Fezomachus. 



red, the latter black at the sides ; metalhorax black, with two red spots at 

 base. Abdomen with segments one and two entirely, three partly, red, 

 the rest black. Legs red. 



(?. Winged. Antennae attenuate towards apex. Wings sub-hyaline, 

 with two indistinct fuscous bands ; stigma broad, radius emitted behind 

 its middle ; ncrvellus antefurcal ; parallel nervure emitted below middle. 

 Abdomen dilated behind, first segment sub-linear, post-petiole one-and-a- 

 half times as long as wide, second sub rugulose. 



Black ; base of antennae, segments two and three of abdomen, and the 

 legs pale red. Length, 4-6 mm. 



Distinguished from F. cursilaiis in the female by the transverse meso- 

 notum, shorter mesosternum, stouter antennae and legs, and by the red 

 mesothorax ; in the male by the colour. 



This species has, I believe, been taken by Sladen at Dover. My record 

 of it (E.M.M., 1900, p. 43) is an error and must be referred to F. vagatia, 

 with which it appears to be much mixed in Britain.

Head with the frons alutaceous and dull ; face broad below, with the 

 cheeks smooth, their costa almost continuous and sulcus deeply impressed ; 

 clypeus apically elevated and rounded ; mandibles scarcely tuberculate 

 basally. Antennae with the basal flagellar joint slightly longer than the 

 second and half as long again as the scape, the fifth twice longer than 

 broad. Meso- and meta-thorax of about equal length, the latter smooth 

 and shining ; petiolar area distinct and oblique, with its basal costa sharp 

 and centrally angulated ; acetabula occupying nearly the whole meso- 

 sternum. Scutellum not indicated. Abdomen somewhat closely punctate 

 and pubescent to the apex ; basal segment somewhat long and narrow, 

 with no projecting spiracles ; terebra as long as, or slightly shorter than, 

 the basal segment. 



Head black ; antennae red and hardly darker towards their apices. 

 Thorax entirely red. Abdomen with the two basal segments entirely, 

 third and fourth more or less, red, the second sometimes discally infuscate ; 

 remainder black with red or flavescent apical margins ; terebra dull red, 

 apically piceous. Legs testaceous with the apical tarsal joint hardly 

 darker. 



cj. Winged. Black, with segments two and three red with a small 

 black discal spot. Legs flavous with the coxae black. Wings ample and 

 hyaline ; stigma broad, black with the base white ; radius emitted from 

 beyond its centre ; nervellus antefurcal ; fenestrae small and broadly dis- 

 creted. Length, 3^ mm. 



This species bears a superficial resemblance to F. corrupior, var. fai/nus, 

 but the petiolar area is decidedly more oblique and the abdominal punc- 

 turation close to the anus. From F. analis it differs in the broader 

 abdomen, denser pubescence, and shorter terebra. The male is also
