in this country. All the specimens in our collections appear to be ^ . nigri- 



cornis, Hofl'm. The differences between the two species are as follows : 



Pronotum without a transverse row of punc- 

 tures near the base. Habitat under bark 

 and in rotten wood (according to one 

 author, generally with ants) . . .A. minutus, Ilerhst. 



Pronotum with a slightly impressed sinuous 

 row of punctures near the base. Habitat 

 in decaying vegetable matter . . . A. xigricornis, i/o^7?i. 



At present no one appears to possess a British Acritus without a row 

 of punctures at the base of the thorax, and living under bark or in 

 rotten wood, but there is every reason to believe that A. vi'mutus will 

 be found, if looked for, as it is widely spread over nearly all Europe, 

 and is not rare. 



COCCINELLID^. 



Mysia oblongoguttata, var. nigroguttata, Dollman, Ent. 

 Record xxiv. l'J12, p. 5o, Plate ii. In form, sculptui'e and size the 

 variety resembles the type-form, but the elytra, which are usually quite 

 free from black markings, exhibit six well detined black spots, and the two 

 dark longitudinal lines on the thorax that are sometimes visible in normal 

 specimens are very strong and thick, the dark colour x-eaching the base 

 and ceasing before apex : the clubs of the antennae, the femora and the 

 tibite in part are also black : the elytra are light testaceous brown with 

 the mai'gins somewhat lighter, with the usual light longitudinal lines 

 and oblong spots, but each of the latter is maiked with a very defined jet- 

 black centre ; the inner spot or centre of disc is very small, but distinct. 



One specimen taken from Pinus si/lvesiris at Oxshott, Surrey, on 

 July 4, 1911, by Mr. Dollman. 



The dark elytral markings are interesting and I have not seen them 

 in any specimen : I have however an example is my collection without 

 locality, in which the whole central portion of the thorax is dark, except 

 a small spot at base, and the tibise are almost entirely black. 



CLERID^. 



Thanasimus rufipes, Brahm. Hoppe. Tschb. 1797, 13G. Closely 

 allied to 2\ foriaicarins L., but smaller on an average, with almost 

 entirely red legs and antennte ; the head and thorax are much more 

 finely and sparingly punctui^ed ; the basal red colour of the elytra is 

 broader, and the first band of white pubescence lies entirely in this red 

 band, and not in the black band, as is the case in T. formicarius. 



Length G|^ mm. 



Nethy Bridge, Scotland. About half-a-score specimens taken by 

 Professor Hudson Beare by beating the tops of felled Scotch fir trees ; 

 it will probably be found in some numbers, now that it has been 

 recognised as a distinct species ; it has been recorded from northern,
