414 ICHNEUMONli^E. 



Genus MAGNIBUCCA, Mori. 

 Magnibucca, Morley, Rev. Ichn. Brit. Mus. ii, 1913, p. 79. 



GENOTYPE, M. testacea, Mori. 



Head posteriorly much broader than the eyes, with the vertex 

 broad and basally margined ; occiput perpendicular and concave ; 

 mandibles stout, margined below, their teeth strongly obtuse 

 apically, with the lower somewhat distinctly the shorter; eyes 

 glabrous, internally parallel and not emarginate ; clypeus apically 

 rounded and slightly but obtusely produced centrally ; face 

 deplanate and not discrete ; cheeks strongly buccate ; frons 

 laterally convex and with a very fine central carina. JVotauli 

 obsolete and hardly impressed ; metathorax convex, with no 

 cariuae ; spiracles elongate, ovate and not small. Scutellum 

 convex, large, apically subtruucate and laterally imrnarginate. 

 Abdomen fully twice the length of the head and thorax, laterally 

 compressed ; basal segment glabrous and linear to its centre and 

 thence gradually dilated to the subapical spiracles. Legs stout 

 and not elongate, with the hind tarsi distinctly spatuliform, with 

 calcaria hardly longer than the breadth of the tibia! apex. Wings 

 not ample ; stigma distinct ; basal nervure subpostfurcal, with the 

 lower basal strongly oblique ; first recurrent nervure emitted 

 before centre of first cubital cell, which is apically strongly obtuse 

 below; second recurrent nervure continuous with the submarginal, 

 more than half fenestrate ; anal nervure emitted far above centre 

 of brachial cell ; all nervures distinct to apices of wings ; nervellus 

 strongly intercepted very slightly below its centre. 



Perhaps this genus is most closely allied in its continuous second 

 recurrent to the Lapliyctes group of the genus Barylypa, but the 

 structure of the head is much closer to Exochilwn ; it is, however, 

 entirely distinct in the structure of its vertex and occiput, and the 

 peculiar coloration, which approximates it to Labrorychus amabilis, 

 Tosq., from Transcaspia. 



306. Magnibucca testacea, Mori. 



Maynibncca testacea, Morley, Rev. Ichn. Brit. Mus. ii, 1913, p. 80. 



A large, stout and entirely testaceous species, with only the 

 ocelli and disc of the second segment black. Head and thorax 

 coarsely punctate, with only the metanotum somewhat smoother. 

 Antenna; (broken) testaceous and multiarticulate, with the thirty 

 or forty basal flagellar joints cylindrical ; scape hardly excised. 

 Wings distinctly flavescent, with the radix, tegulae and stigma 

 fulvous. 



Length 23 millim.
