lONaiCOEN BEETLES OF JAPAN. 233 



The peculiar colour and thread-like markings of the elytra are 

 nearly the same as in X. Jiirctis, Gebl., with the exception that 

 jr. alhif-lis Has a large, triangular, grey-white spot at the sutural 

 apex. But the two species difi'er very greatly in many points of 

 structure : in X. Mrcns th.e frontal carinas are divergent behind, 

 and there is no single carina in continuation along the vertex ; the 

 antennae are formed of shorter and rather more triangular joints 

 instead of being filiform ; the thorax is very broadly dilated and 

 rounded (" globosus," as Gebler describes it), in X. alhifilis it is 

 oblong-ovate, and the elytra are rounded at the apices and of less 

 elongated outline in shape. 



The Amur specimen, which differs a little in elytral markings 

 from Mr. Lewis's series from Japan, was obtained from the same 

 collection, made on the Am.ur, which contained examples of 

 X.. hircus. The species appears not to have been described by 

 any of the numerous writers on East-Siberian Coleoptera.

 race (margine antico nigro escepto) supra sanguineo, elytris 

 basi, fascia subrecta subbasali (suturaque inter fasciam et scu- 

 tellum), fascia ante-apicali (vittaque marginali inter fasciam et 

 apicem) cinereis (interdum testaceo-cinereis) ; subtus nigro, 

 cinereo-pubescenti,metathoracis episternis, apice ventrisque seg- 

 mentis 1-8 postice densius cinereis ; fronte medio sex-carinata ; 

 thorace subgloboso, dorso grosse intricato-ruguloso ; elytris cur- 

 vatim modice angustatis, apice subrecte-truncatis angulis acutis, 

 adpresso-pilosis. Antennae in utroque sexu filiformes nee apice 

 incrassatae. Long. 9-10 millim. S $ .

In X. pyrrhoderus the middle frontal carinae are obsolete and 

 undistinguishable, but the lateral carinas very acute ; the antennae 

 are greatly thickened (excessively so in $) after the 4th joint; 

 the thorax finely intricate rugulose-punctate and red beneath as 

 well as above ; the elytra have no part of the suture grey, and 

 want the apical lateral grey streak ; lastly, the body beneath is 

 differently clothed with grey pile, the middle being shining 

 black, and one fascia only being present across the ventral 

 segment.
