GrENOTYrE, Ichiieumoii aunculatHS, F. 



Head very smooth, baccate posteriorly, with the vertex deeply 

 emarginate and the cheeks large ; clypeus hardly discrete basaily, 

 its apex dentiformly produced centrally; mandibles stout and 

 bidentate, with the teeth of equal length ; eyes entire and not 

 Bmall. Antennas fihform and fully as long as the body, with their 

 apices subatteuuate ; scape obliquely truncate apically. Meta- 

 notal arese wanting ; spiracles oval. Abdomen petiolate, moi'e or 

 less compressed laterally ; basal segment deplanate and straight, 

 parallel-sided, with tlie spiracles before its centre; terebra short 

 and not extending beyond the anus. Hind legs longer and stouter 

 than the front ones, with bicalcarate tibiae, more or less iucrassate 

 tarsi and closely pectinate claws. Areolet wanting. 



Range. North and Central America, Europe, Himalaj^as. Erro- 

 neously recorded from New Zealand. 



This species is, I think, best recognised by the peculiarly large 

 and shining head, its centrally produced clypeus and distinctly 

 compressed abdomen. Originally its main feature was the iu- 

 crassate hind tarsi, and this is very conspicuous in certain species, 

 though but feebly developed in the Indian ones ; on account of it 

 and the compressed body this genus was thought at first to be 

 allied to Anomalon and it was even retained in the Ophionin^ by 

 Holmgren in 1858, though in the aberrant group of the Ban- 

 chides, with which it obviously has nothing in common. It 

 certainly belongs to the Ctenopelmid group of the Tryphonin^ 

 and is somewhat closely allied to Euceros, Grav., the species of 

 which have, like it, been bred from Lepidopterous hosts. Scolo- 

 hates is also said to prey upon Syrphid flies and TEoS'tiiredinid^ ; 

 but cf. Bassus Icetatorius (p. 278).
