Genus IDECHTHIS, Forst. 

 Idechthis, Forster, Verh. pr. Rheinl. 1868, p. Io4. 

 GENOTYPE, not cited. 



Head transverse and not broad ; clypeus apically very broadly 

 rounded and not produced; eyes internally parallel and not 

 emarginate ; metanotum striate and not rugose, with the petiolar 

 area not excavate ; spiracles small and circular : abdomen with 

 the spiracles of second segment very distinctly beyond its centre; 

 terebra not extending beyond anus ; hind calcaria shorter than 

 second joint of their tarsi ; areolet entire and pentagonal, with 

 the radius angled above it ; anal nervure emitted exactly from 

 centre of first recurrent ; nervellus straight and not intercepted ; 

 basal abscissa of radius in hind wings shorter than their recurrent 

 nervure. 



Range. Palsearctic Region. 



It is very improbable that the genus LatJirostizus, Forst., is 

 distinct from the present one ; my diagnosis above includes the 

 characters of both, since they are combined in the species herein 

 comprised. Cameron incorrectly placed his species in Tranosemu, 

 Forst. (Verh. pr. Rheinl. 1868, p. 157), with considerable doubt ; 

 but it differs from it in having the second segmental spiracles 

 distinctly behind the centre.
