convex behind than in E. mutilaiun ; t,he punctuation almost as in that species, 

 but slightly sparser. Legs darker in colour than in R. mutilatus, the tarsi longer 

 and more slender. 



This species was discovered during the past summer by my old 

 friend T. G. Bisbop and myself, at Grantown, in Inverness-shire. We 

 secured fifteen individuals by shaking twigs and branches of dead 

 birch. They differ but little, except in size, and in the colour of the 

 antennfe and legs, and in the latter respect the variation is but slight. 

 Had 1 seen but one specimen of this insect, I should have treated it 

 as a variety of M. mutiJalus, but the specimens agree so well inter se, 

 that I think it will prove tliat we have really two closely allied s[)ecies, 

 a. hishopi being of darker colour, more slender build, with deeper 

 impression behind the base of the elytra, which, moreover, are a little 

 shorter, and are more convex behind. 



Eabocerus championi, sp. n. 



^neo-niger, nitidus, antennarum bast rufa, tihiis tarslsque fusco-testaceis, 

 illis ad basin Jlavis ; rostro prothoraccque hrevissimis, hoc transvevso, for titer 

 -punclato, profunde quadri-imprcsso ; elytris post-scutelliini im2}ressis, seriatim 

 punctaiis. Long. 2f mm. 



Although 1 have seen but a single example of this species, and 

 it is evidently closely allied to R. mutilattcs, yet the very short rostrum 

 and thorax render it highly probable that it is distinct. There is no 

 smooth sclerite between the front and the labrum : this would be a 

 highly distinctive character, but as the specimen has had the front of 

 the head a little damaged, it is just possible this may not be a natural 

 condition, though I believe this to be improbable. 



The si)ecimen described was found by Mr. Champion, on July 

 20th last, at Evolena, in the Val d' Kerens, Switzerland, by beating 

 the dead branches of an old sallow. 



We have besides R. foveolatus and B. hishopi, another species of 

 the genus in Britain, viz., B. mutilatus, which is supposed to be the 

 S. {Colposis) virescens of Mulsant. JR. mutilatus appears to be 

 everywhere a rare insect ; a description (;f it has recently been 

 published by tSahlberg (Medd. Soc. Fauna fenu. 29, 1901, p. 40). 

 Through the kindness of Dr. Sahlberg 1 have before me the specimen 

 on which this description was based, and have thus been able to 

 compare it with British examples, as well as with an individual from 

 Vienna, in the collection of Mr. Champion. The Finland specimen 

 agrees with the one from Vienna, but they differ a little from our own 

 examples in colour. As these latter are very few in number, and
