DESCRIPTION OF A NEW STAPHYLINID BEETLE. 

 BY DAVID SHARP, M.A., F.E.S. 



HoMALOTA (hydkosmecta) muiri, sp. n. 



Depreasa, nigra, tihiis extrorsum tarsisque sordide testaceis, omnium 

 denslssima punctata, puhescentia densa cegre discernenda ; antennis gracilibus, 

 extrorsum-leviter crasxiorihiis ; capite suhquadrafo,prothorace Jiaud transversa, 

 posteriiis leniter angustato. Long. 2^ — 2-2" mm. 



Tliis delicate little creature belongs to a division of Homalota 

 containing but few species, from all of which it may be separated by its 

 blacker coloiu' and the excessive minuteness of its dense pubescence. 

 Its place is next to longuJa, Heer. H. mairi is distinguished from that 

 species by the characters just mentioned, as well as by the fact that the 

 antennte certainly become slightly stouter at the extremity. The thorax 

 appears to be quite as long as broad, but measurement shows that the 

 width is slightly greater, in proportion of about 9 to 8. The external 

 differences of the sexes are very slight. The species was first captured 

 by my friend, Mr. F. Muir, a few days ago, in the shingle on the banks 

 of one of the small rivers here. A return to the spot I'esulted in a few 

 additional specimens. The insect, however, is a very difficult one to 

 secure. The shingle must be pushed into the water, and then the beetle 

 is immediately seen floating on the surface ; but so active is it, that it 

 takes flight almost as quickly as the eye can see it.

PERICLISTA PUBESCENS, Zadd., AN UNRECORDED BRITISH 



SAW-FLY. 



BY THE REV. F. D. MORICE, M.A. 



{Pres. Ent. Soc. Lond.). 



I am again, as last year (Ent. Mo. Mag., July, 1910), indebted 

 to my friend Mr. Horace Donisthorpe for the pleasm-e of making 

 an interesting addition to the List of British Tenthredinidse. On 

 April 28th last he swept or beat from oak leaves at Porlock (Somerset) 

 a V Periclista, evidently differing from anything previously known iu 

 this country, and agreeing completely with Zaddach's description of 

 his Selandria (sic) puhescens. 



Before venturing, however, to record it under that name, I
