The very small size of tliis insect (though, of course, stouter, it 

 is scarcely, if at all, larger than my largest specimen of Smicronyx 

 jungermannics) renders any lengthened comparison with other British 

 species unnecessary ; but it may be remarked that it differs from the 

 smallest L. ovatulus in its lighter coloured and more slender legs, of 

 which the femora are untoothed beneath and the anterior tibiae almost 

 straight, with no projection on the inner side and a very minute 

 apical spur, its more slender antenna?, less stout rostrum, which is 

 not so evidently thickened before the insertion of the antenna3 and is 

 much more strongly punctured (the punctures running into irregular 

 longitudinal furrows), its more ojDaque and much more closely punc- 

 tured thorax, the interstices of which are alutaceous and in parts 

 almost converted into wrinkles, &c. From ollongiolus, our only other 

 known species, its much less size and shorter and broader build, 

 duller and more closely punctured head and thorax, the more evident 

 humeral angles and more marked striae of its elytra, and its antennae 

 being inserted not so near the apex of the rostrum, will serve to 

 distinguish it. 



Being unable to make this species satisfactorily accord with any 

 of which the descriptions are known to me, I sent it to M. Ch. 

 Brisout de Barneville, who agrees with me in thinking it as yet un- 

 described. He considers it to come nearest to certain varieties of 

 his L. pyreiKsxis^ from which it differs in its rather more massive 

 form, stronger punctuation, and thicker rostrum. 



Two examples, both females, were found by Mr. J. J. Walker 

 during April last, at Faversham, Kent, in moss.

Notes on certain British Coleoptera. — 



Bemhidium U-striatum. — Thomson (Opusc. Ent., fasc. iv, p. 361) bo names 

 B. velox, Er., nee Liun. (= impressum), which ho recognises as a distinct species 

 from celer (lampros) by its rather larger and wider build, the greater dorsal de- 

 pression and less lateral rounding of its elytra, which have 7 (not 6) more lightly 

 impressed strije, with wider and flat interstices, and the more acute posterior angles 

 of its more strongly transverse thorax. The insect (race or species) is well known 

 to occur in this country. 



Calathus nuhigena, Hal., is distinguished from melanocephalus as a good species 

 by Thomson, I. c. p. 364, by its antennae before the base and its tarsi being fuscous, 

 the usually infuscate disc of its thorax, which sometimes is (with the antennae and 

 legs) entirely blackisli, its more shining elytra, which are less acuminate behind, 

 and its habitat. Apart from colour, there seems to me no difl^erence between the 

 two ; if anything, the elytra appear to me to be inore acuminate behind in the dark 

 form, and I hare taken dark melanocephahis at Shirley.
