fore Herr Schaum's doubts on the value of Kuster's species (cf. Catal. 

 Coleopt. Eur. Berlin, 1859) were well founded. 



Acwpalpus longicornis, Schaum. 



This little Acupalpus is one of the numerous instances of per- 

 plexity and trouble in which the conscientious study of authors may 

 place you. After having spent much time without ascertaining the 

 specific name of my Consputus-Vike specimens, I had therefore con- 

 cluded that they represented an imdescribed species, which, although 

 evidently aUied to Schaum's longicornis (Berlin. Entom. Zeitschr. i. 

 145), could not be identified with his description*. Having by 

 mere chance read that acute author's new description of the same 

 (Naturgesch. d. Insect. Deutschl. I. i. p. 622), (which is so different 

 from the former, that, except the identity of the name, one would 

 believe it quite another species,) I have just in time been enabled 

 to withdraw my manuscript. 



The specimens under my inspection were caught in Albania 

 by S. S. Saunders, Esq., and belong to Mr. W. W. Saunders. They 

 are a trifle smaller, reaching not above 3| miUim. ( = lf lin. Par. 

 mens. = Ih lin. Angl. mens.). Their labrum is of a reddish hue, like 

 the sides of the thorax, of which the red margin is well circumscribed, 

 with the disk quite black, as wcU as that of the elytra, in which the 

 large triangular humeral patch is, together with the narrow limb, of 

 a well-defined pale-yeUow hue. They quite agree with Schaum's 

 latter description, made upon matui'e specimens, and which alone 

 applies to the species. 



MiCROLARiNtJS, Hochhuth, and Rhinocyllus Lareyriii, Jacq. Duval. 



It is evident to me that RJiinoc. Lareynii, Jacq. Duv. (Ann. Soc. 

 Entom. France, 1852, p. 714), belongs to the genus Microlarinus, 

 Hochh. (BuU. Soc. Imp. Nat. Moscou, 1847, ii. p. 540). 



But the most interesting, as a geographical point, is its specific 

 identity with Hochhuth's Microl. rhinocylJoides, of which I have no 

 doubt, having carefully compared several extreme specimens of Bhin. 

 Lareynii with the excellent description of the Russian author. 



This brings an addition to the genera of the European fauna ; 

 the valuable characters pointed out by Hochhuth are most clear, 

 besides a difference of habit which would destroy the homogeneity 

 of RJiinocyllus. 



No doubt this species will be found along the zone extending be- 

 tween these two extreme points, viz. Caucasus and South France ! 

 * That description was very likely made upon immature specimens.
