TRICHOMMA. 429 



mouth ; eyes broader below, internally broadly emarginate and 

 distinctly pubescent ; clypeus obsoletely discrete basally, 

 snbprocluced centrally at the apex ; labruin concealed ; mandibular 

 teeth acute, with the lower slightly the shorter. Antenna? hardly 

 longer than half the body, with the scape apically subtruncate 

 and hardly emarginate. Mesouotum rugosely punctate, with the 

 notauli often very indistinct; metathorax extending distinctly 

 beyond base of hind coxa3. Scutellum flavous, apically reflexed or 

 subemarginate. Abdomen slender and compressed ; terebra longer 

 than the basal segment, with linear valvulse. Hind legs some- 

 what stout, with the claws slender ; tarsi incrassate, with the 

 basal joint about double the length of the second, trochanter 

 longer than trochanterellus. Anal nervure emitted from nearly 

 the centre of the first recurrent, lower basal oblique and post- 

 furcal ; nervellus neither intercepted nor geniculate. 



Range. United States, Europe, Africa, Iudia> Ceylon, Malaya. 



The distinctly pilose eyes will at once distinguish this genus 

 from the remainder of the ANOMALIDES, except certain Ayrypon, 

 in which they are but obsoletely pubescent. 



The Indian species have the head anteriorly buccate and 

 posteriorly truncate, with the orbits very broadly pale.

c? $ . A black and linear species, with flavous markings on the 

 head and thorax. Head glabrous, with white pubescence and 



adopted in place of Anomalon, Grav., in his " British Entomology" (pi. et fol. 

 736, April 1839), as he there explains: "Having published the genus 

 Anomalon before Gravenhorst's work appeared, it may appear necessary to 

 give my reasons for rejecting some of his names in the Guide. 1st, BASSOS of 

 Fabriotoa is Gravenhorst's 3rd family of Cryptus, siductorius being the type 

 given in the Piezatorum ; 2ndly, Jurine's 1st family of ANOMALON, which of 

 course is his type, Gravenhorst has called Bassus. Srdty, Jurine's 2nd family 

 of Anomalon I have called TIIERION, because it is not trie typical Anomalon'}' 

 The type of his genus Therion is Ichneumon amictus, Fab. (*Syst. Ent. p. 341), 

 but he also catalogues, without description, species now referred to four or 

 five different genera of ANOMALIDES; and the only new species he brings 

 forward was thought by Bridgeman and Fitch, in 1884, to be a variety of a 

 Gravenhorstian Anomalon. If Therion be adopted at ali, it must be Schizoloma,. 

 Wesm., and not Trichomma, which falls.
