TRICirOMMA. 429' 



mouth ; ejes broader below, internally broadly emarginate and 

 distinctly pubescent ; clypeus obsoletely discrete basally, 

 subproduced centrally at the apex; labriun concealed; mandibular 

 teeth acute, with the lower slightly the shorter. Antenmc hardly 

 longer than half the body, with the scape apically subti'uucate 

 and hardly emarginate. Mesouotum rugosely punctate, with the 

 notauli often very indistinct ; metathorax extending distinctly 

 beyond base of hind coxae. Scutelkun iiavous, apically reflexed or 

 pubemarginate. Abdomen slender and compressed ; terebra longer 

 than the basal segment, with linear Aalvula;. 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 lirst recurrent, lower basal oblique and post- 

 f ureal ; nervellus neither intercepted nor geniculate. 



Ramje. United States, Europe, Africa, India, Ceylon, Malaya. 



The distinctly pilose eyes will at once distinguish this genus 

 from the remainder of the Anomalides, except certain Ayriipon, 

 in which they are but obsoletely pubescent. 



The Indian species have the head anteriorly baccate and 

 posteriorly truncate, with the orbits very broadly pale.

c? 2 . A black and linear species, with tlavous markings on the 

 head and thoi'ax. Head glabrous, with white pubescence and 



adopted iu place o? Anomalon, Grav., in his "British Entomology" (pi. et fol. 

 730, April 1S3D), as be tliere explains: "Having publisiied the genus 

 Ano'inalon before Gravenliorst's work appeared, it may appear necessary to 

 give my reasons for rejecting somic of bis names in tbe Guide. 1st, Bassus of 

 Fabricius is Gravenliorst's ord family of Cri/ptux, liiducloriut^ being tbe tvpt- 

 given in tbe Piezatoriim ; L'ndly, J urine's Ist family of Anomai.on, wliicb of 

 course is his type, Gravenhors( has called Bassns. .'Jrdly, Jurine's liiid faniilv 

 <>i' AiioDialon I have called Tiii'.uroN, because it is not tbe typical Anomalon." 

 Tlie type of his genus Therioii is Ichiiftunon amictits. Fab. (Syst. Eiit. ]). 341), 

 but be ;ilso catalogues, without descri[)tion, species now referred to four or 

 five dilferent genera, of Anomai.idks ; and tbe only new species be brings 

 forward was tiiongbt by Bridgenum and Fitcb, in 1SS4, to be a varielv of a 

 Gravenborstian Anormloii. If 'I'hirtoii be adopted at ali, it must be ><chi~oloinu, 

 AVesm., and not Trichumma, whicli falls.
