the pattern on the elytra is almost exactly as in E. notata but the 

 scales are not so closely set ; from E. notata however the present 

 species differs inter alia in its less robust build and especially in 

 the antenna} being inserted in the male not much (and in the 

 female scarcely) in front of the middle of the rostrum, while in $ 

 notata their insertion is distant from the a])ex scarcely a quarter 

 of the length cf the rostrum and in the ^ scarcely a third. The 

 rostrum is not at all unlike that of E. gravis but scarcely so long, 

 and in the female less strongly curved ; from this species, however, 

 the presence of a pattern on the upper surface and the much 

 feebler constriction of the prothorax anteriorly, inter alia, will 

 I'eadily separate E. tnunda.

Emplesis assimilis, sp.nov. 



Elongata ; i-obusta ; ferrnginea, squamis cinereis confuse 

 vestita ; funiculi articulo 1° quam 2"^ duplo longiori, ceteris 

 sat brevibus, ultimis vix transversis.

Maris rostro quam prothorax vix longiori leviter arcuato ;

Feminse rostro quam prothorax sat longiori, sat fortiter 



arcuato ; antennis vix ante rostri medium insertis. 

 This species is extremely close to E. notata, Blackb., but the 

 sexual characters are very distinctive ; apart from these I find 

 little difference between the two species except that the mottled 

 appearance on the elytra resulting from the mingling of ashy and 

 dark ferruginous scales is more confused in assimilis, — so that the 

 quasi-pattern which in E. notata is fairly well defined is here very 

 obscure. The rostrum does not differ much in the males of the 

 two species except in the insertion of the antennae being a good 

 deal nearer the apex in E. notata. The rostrum of E. assimilis is 

 much longer in the female than in E. notata and is very much 

 more strongly arched, with the insertion of the antennae scarcely 

 at all in front of the middle. Compared with E. munda, Blackb.,
