abdomen and the edges of the abdominal segments more Or less rufous-piceous ; the 

 legs and base of the antennae testaceous. O. annularis is entirely rufous-testaeeous, 

 with the exception of the head and middle of the abdomen, which are somewhat dusky. 

 O. brachyptera is usually intermediate in its colouring between the above-mentioned 

 two species; its antennae, thorax, elytra, and the base and apex of the abdomen, are 

 ferruginous. Here the antennae, if bent backwards, would nearly extend to the apex 

 of the elytra (the same organs would fall considerably short of the same point in the 

 other two species) ; the intermediate joints are moderately transverse, and the terminal 

 joint is fully twice as long as broad. The elytra are rather longer, and the punctuation 

 is more distinct and somewhat rugulose, which is not the case in O. misella and O. 

 annularis. 



"3. Of the specimens of Trechus obtusus which are exhibited, one is from the 

 Continent, having been kindly sent to me by Dr. Schaum; the second is British, and 

 stood in my collection for many years under the MS. name ' laevis,' it having been so 

 named by me and separated from the T. minutus, chiefly in consequence of the almost 

 total obliteration of the strise of the elytra. Jn the fifth volume of Stephens' ' Illustra- 

 tions' (Mandibulata), and in the 'Manual' by the same author, an insect is very 

 briefly described under the name 'T. leevis, Waterh.^ ; whether the description was 

 taken from this specimen I am not aware, but as there is no insect in Stephens' col- 

 lection to represent the species, the exhibited specimen is probably the original of the 

 description. However this may be, it will be seen by the members present that the 

 , British specimen agrees perfectly with the continental one, and differs from T. minutus 

 chiefly in having the elytra shorter, more convex, and of an ovate form, the broadest 

 part being in the middle (whilst in T. minutus the elytra are broadest behind the 

 middle), and the strife of the elytra being all obliterated, or very nearly so, excepting 

 the three nearest the suture. In T. minutus there are at least four distinct striae on 

 each elytron. The last-named insect, moreover, is provided with perfect wings, whilst 

 in T. obtusus the wings are rudimentary. 



" 4. For Bembidium Mannerheimii, recently detected by Mr. Rye amongst 

 our British species, I have a new locality to record ; the specimens exhibited were 

 taken by me at Darenth Wood." 



The Secretary read a letter from Dr. Hagen, of Konigsberg, in which, after 

 thanking the Society for having elected him one of its Honorary Members, he 

 expressed a hope that British entomologists would assist him in rendering more perfect 

 his recently-published ' Bibliotheca Entomologica'; if the entomologists of this 

 country would communicate to this Society every error or omission, with respect either 

 to the authors or their works, which they noticed in the ' Bibliotheca,' and such addi- 

 tions as from time to time became necessary, and the Society would communicate the 

 same to him (Dr. H.), he trusted that, by the assistance and co-operation of this and 

 other Societies, which had been requested to do likewise, a future edition of his recent 

 work might be made a good foundation for a complete and perfect record of ento- 

 mological bibliography. 



The President mentioned that Professor Lacordaire, of Liege, in a letter returning 

 thanks for his election as an Honorary Member, had enclosed a photograph of him- 

 self, in the belief that this Society, like that of France and other scientific bodies, was 

 forming a collection of likenesses of its members. The Council had taken the subject 

 into consideration, and having regard to the regret which was now felt at the absence
