GENOTYPE, Ichneumon scotoptents, Grav. 



Head with the eyes not internally emarginate ; clypeus apically 

 rounded and strongly punctate ; mandibles not stout, with the 

 lower tooth hardly the longer. Thorax with no notauii, epomife 

 or areae, and the epicnemia abbreviated above ; metapleural carinse 

 distinct. First abdominal segment short and not dilated basally, 

 with the spiracles before centre, somewhat prominent and emit- 

 ting no carinae to apex of segment ; postpetiole with no lateral 

 margin ; second segment with no basal lateral cariuse or thyridiL 

 Legs not slender, with tibial calcaria short ; tarsal claws very 

 small, simple and hardly curved. Areolet distinct, irregularly 

 oblique, petiolate, neither large nor rhomboidal ; nervellus of hind 

 wings intercepted below its centre. 



Range. United States, IS orth-West Europe, Himalayas. 



This genus differs from Syndipnus, of which it was considered 

 to form a section by Thomson (loc. cit.\ in the possession of a 

 distinct areolet, etc. So little has been known of the single 

 Palaearctic representative of this genus, Ichneumon scotopterus r 

 Grav. (Mem. Ac. Sc. Torino, 1820, p. 377), that Marshall left it 

 in 1872, as placed by Stephens in 1835, in the genus Tryplion,. 

 and in 1880 Bridgman redescribed it (Entom. xiii, p. 54) under 

 the name Perilissus fumatus. Two American species are also- 

 known. The testaceous body and dark wings of the Oriental 

 species render it a very conspicuous insect. 



233. Labrossyta nigriceps, Cam. 



Lapaphras nigriceps, Cameron,* Journ. Bombay Nat. Hist. Soc, 

 1902, p. 428 ($). 



. A testaceous species, with the head and apices of legs black 

 and the wings distinctly infumate. Head transverse, with the 

 temples subbuccate behind the prominent eyes ; face nitidulous. 

 deplanate and longitudinally impressed on either side, distinctly 

 discrete from the apically strongly punctate and prominent 

 clypeus ; mandibles weak, with the apical teeth subequal ; palpi 

 infuscate ; labrum exserted and ferruginous ; vertex narrow, 

 Antennce a little shorter than the body, black and filiform 

 throughout. Thorax immaculate testaceous, with the notauii 

 wanting; metathorax shining, convex, pilose and punctate, longi- 

 tudinally unicarinate, with the petiolar area distinctly carinate, 

 lateral carinae curved and not weak, spiracles minute and circular. 

 IScutellum testaceous, convex, pilose and obsoletely punctate.
