Eiichs., Aube, &c., but is readily distinguished by the comparatively large size of the 

 central fovea on the back of the thorax, this being nearly as large as the lateral fovete, 

 whilst in B. impressa it is very small, as in B. Juncorum ; moreover, the male sex of 

 the present insect has the anterior trochanters armed with a spine, and the first abdo- 

 minal segment has a small curved groove at the apex, enclosing a small, slightly raised 

 area. The middle tibia has a distinct spine at the apex in the same sex. Usually the 

 red of the elytra is darker than in B. impressa. 



On the Continent this species is said to be found in the neighbourhood of salt or 

 brackish water, and such was the case with most of his specimens, these being taken at 

 Sheppey, Southend and Gravesend, but it does not confine itself to such situations, 

 since Mr. W. found a specimen at Hawkhurst, in Kent, and a second in the Crystal 

 Palace.

Mr. Waterhouse has in his British collection a female Bryaxis which in size 

 and colouring greatly resembles B. Helferi, but which is certainly distinct. He has 

 no note of its locality. When compared with B. Helferi it differs in having the abdo- 

 men more finely and less thickly punctured, and hence this part is more glossy, and 

 the two striolae at the base of the first segment are much more widely separated:* the 

 insect is furthermore narrower, and has the humeral augles of the elytra more promi- 

 nent. He has in his possession a male insect, from Paris, named B. Lefebvrii, which 

 agrees most closely with the present insect in the points just noticed, and it agrees 

 with the characters laid down for B. Lefebvrii (including the small size of the spur to 

 the middle tibise), but here he finds a small spur to the anterior tibiae, and he could 

 see no spur to the hind tibiee : in the descriptions the spur is said to exist on the 

 middle and posterior tibiae. 



The third species belongs to the same section as B. fossulata, having the abdo- 

 men simple in both sexes ; the anterior coxae unarmed in the male, which sex is only 

 distinguished by a small spine at the apex of the intermediate tibiae ; the three foveas 

 on the thorax nearly equal. In size it is equal to B. sanguinea, and its antennae are 

 as long as in the female of that insect, and hence longer than in B. fossulata : its 

 colour is rufo-piceous ; the elytra red, with the margins dusky ; the legs fusco-testaceous. 

 This species being apparently undescribed, the name Bryaxis simplex was proposed 

 for it. A detailed description was communicated to the Meeting. 



Lastly, Mr. Waterhouse called attention to a fine species of Anobium which had 

 just been found by Mr. Turner in the neighbourhood of London: this would most 

 probably prove to be the A. denticoUe of Panzer ; but the only specimens Mr. W. had 

 had an opportunity of examining were two in Mr. Stephens's collection, one in very 

 bad condition. Mr. Turner's insect differed from these in being very much larger, and 

 apparently rather broader, being very nearly as large as A. tessellatum ; its scutellum 

 was apparently broader, and of a truly quadrate form. 



•* In these insects usually may be seen three transverse depressions at the base of 

 the abdomen, close to the edge of the elytra, and the central depression is bounded 

 by two nearly longitudinal but slightly diverging striae ; in the male of B. Helferi the 

 space between the striae is very nearly equal to one-third of the width of the convex 

 part of the abdomen ; in the female it is less, since it scarcely exceeds one-fifth ; whilst 

 in the female insect which Mr. W. supposes to be that of B. Lefebvrii, the space 

 between the striae is decidedly more than one-third of the width of the abdomen, not 

 includincr the subreflected lateral margin.
