XrLONOMUS. ~, 



narrower ; aiinellus smooth and subobsolete ; i3agellar joints cylin- 

 drical, gradually decreasing in length and apically hardly nodulose. 

 Thorax cylindrical, much longer tlian high ; no'tauli distinct and 

 elongate ; epomise and epicnemia distinct ; metanotal area? and 

 apophyses well defined ; spiracles oblong or linear. Scutellum 

 more or less convex, triangular and apically obtuse. Abdomen 

 subsessile, somewliat deplanate discally, iinely punctate and rarelv 

 shining; of c? elongate, sublinear or a little dilated !o\^ards the 

 apex, narrower and usually twice as long as the thorax ; of 2 

 shorter and as broad as the thorax, oblong or oblong-ovate. 

 Basal segment longer than broad, scabriculous, usually with 

 distinct longitudinal carinte, parallel-sided or (in 2 ) apicallv 

 dilated, sometimes laterally impressed, with the spii-acles slightlv 

 behind the centre ; eighth segment exserted in $ . Terebra 

 emitted before the apex, not or only slightly longer than the 

 abdomen. Legs normal or subelongate ; anterior tibia?, especiallv 

 iu 5 , incrassate and constricted at the base ; tarsal claws small 

 and simple. Wings somewhat narrow ; areolet entirely wanting ; 

 lower wings with the radial abscissa shorter than the recurrent 

 nervure.

Cijanox'orides and S^nJoxorkUs, Cam. (Jour. Str. Br. Eoy. As. 

 Soc. 1903, pp. 141 et 143) may be useful here as subgenera. 



This genus differs from Xorides in the rugulose petiole and 

 broader basal segment, as well as in its internally parallel eyes, 

 which in the latter are subcouvergent towards the apex ; its 

 I'elationship with Banclius tiwdArotes is remarked upon by Graven- 

 horst. The species are few in number iu Europe, though more 

 numerous in America, 'and Smith has described several from the 

 Malays Archipelago and Japan ; they are well known to prey 

 beneficially on larvae of Longicoi-n Coleoptera, which are often so 

 destructi\'e to forest and other trees.
