of the perfect male insect, a small creature with little power of flight, in localities 
where water was absent. Accoi'ding to a letter received from M. Snellen Van 
Vollenhoven, the larva occurs " in millions" in the wood of La Haye, in Holland. 
May I ask obsei-vers to keep a look-onfc for this most peculiar insect ? — E. McLachlan,

Tenthredo olivacea of King, a new British saw-fly. — Of this I took a single 
specimen at Rannoch, in June, 1865, and have received five examples from Dah-y, 
Ayrshire, taken by Dr. Sharp. It much resembles the common and variable T. 
scalaris, but may be at once distinguished by its olive-green, instead of bright 
green, gi'ound-colour, and by the thoracic black markings, which here form only 
slender lines marking the sutures of the lobes ; whereas in scalaris they are more 
conspicuous, and form distinct blotches, even in the least-marked individuals. — Id. 
Occurrence of a genus of Coleoptera nevj to Britain. — I have just received for 
determination from Miss Catherine C. Hopley, of Lewes, a S specimen of PhosphcB- 
nus hemiptsrus, Geoff., captured in her garden at that town. Another example has 
been taken. This luminous beetle occurs commonly in France and Germany, and 
is distinguishable from the " Glow-wonn" by its much smaller size and long and 
stout antennae, and the very short gaping elytra of its male. A full account will 
appear in our next No. from Miss Hopley's pen. — E. C. Rye, 7, Park Field, Putney, 
June, 1868. 
Capture of a species of Omia.s new to Britain. — During the last and the early 
part of the present month, I have taken in Hackney Marshes a few examples of 
both sexes, including a pale form, of an Omias evidently different from our recorded 
species, and which Mr. Rye thinks is to be referred to the O.pellucidus of Schonherr. 
Of those already known as British, it most resembles 0. hrunnipes, ivom which 
it may readily be distinguished by the thin scattered grey hairs on its elytra. It 
is a little larger than that abundant insect (pallid forms of which have, I believe, 
before now been mistaken for it), dark pitchy-brown in colour, with reddish-yellow 
antennae and legs, a strongly-punctured rostrum, which is furrowed towards the 
apex ; a wide, flattish, laterally much rounded, strongly and somewhat irregularly 
punctured thorax, and strongly punctate-striate elytra. The anterior femora are 
untoothed, but the tibiae are curved inwardly towards the apex, where they terminate 
in a sharp point. The male is much narrower than the female. I observe that 
Stephens, in the " Manual," describes 0. pellucidus, Schon., and does not prefix his 
desideratum mark ; but, from the absence of the insect in our more reliable recent 
Catalogues, I presume that in this case, as in many others, he copied the descrip- 
tion from the original author, under the erroneous idea that he really possessed 
the species. — W. G. Pelekin, 55, Sandringham Road, Dalston, June, 1868. 
Capture of Aphodius villosus. — I captured a very few examples of this rare 
species on the 8th inst., crawling over the diy sand-hiUs at Llandudno. It is just 
ten years since Mr. Cooke found his single specimen under similar circumstances 
at Southport.— Jos. Sidebotham, 19, George Street, Manchester, 16th June, 1868.
