and tlie .somewhat long and slender legs. This is nieiely tluown 

 out as a hint to any Entomologist who will revise the various 

 species of" Cretnaslocheilns and distribute thein into natural sub- 

 genera. 



[P.S. Mr. Saunders having placed in my hands the two insects 

 above described, with a view to the examination of their trophi 

 and the investigation of their generic characters, with reference to 

 the Monograph of Dr. Burmeister recently published upon the 

 Cremaslocheili in Dr. Germar's " Zeitschrift fi'ir die Entomologie," 

 the following remarks have been rendered necessary : — In their 

 narrow mentum, exposing the base of the maxillae, the elongated 

 body, rounded sides of the protliorax (which is narrowed before 

 and behind), in the channelled mentum, in the galea and mando 

 of maxillae being bidentate, in all the tarsi being bidentate and 

 longer than the tibiae, these two species come into Burmeister's 

 new genus Ccenochitus'f (Germar's Zeitschr. vol. iii. p. 250, 2G8) ; 

 but all the species of that genus are from South Africa. From 

 Genitchus they differ in having the bidentate galea and mando, the 

 mentum not tuberclcd, and the tibial not 3-dentate; and from 

 Centrognat/ms {Guerin, an Indian genus formed of a single species) 

 in the mentum not tubercled, and the galea not 1-dentate ; from 

 the other CrcniastochcUldes they ditt'er in having the mentum nar- 

 rowed at the base. See also Burmeister, Handb. d. Ent., vol. iii. 

 p. 667.-7. 0. W.']
