bottle being flat on the top and bottom is also an advantage. The accompany- 

 ing sketch, drawn to exactly half the actual size, will I hope make the con- 

 struction of this killing bottle quite clear. 



The glass used is that made for " sight feed lubricators," 4 in. x 2^ in.=2£ 

 in. inside measurement — the glass being J in. thick. For A, a ring was cut out 

 of i in. leather, 2£ in. diameter full, the width of the ring about f in., a piece 

 of brass wire gauze was then " blocked on " — in practice a piece of muslin or 

 leno over the gauze is an advantage ; this was then forced into the glass to, say 

 1 in. from end ; below this, to hold the ether, a rubber valve (B) was cut, A in. 

 thick, 2i in. diameter full, and a small tin, 1 in. diameter, J in. deep, was let 

 into the middle to hold the cotton wool ; the base of the India rubber must 

 project below the glass to enable it to be taken out when more ether has to be 

 added, the advantage being that the bottle has not to be opened to put in the 

 ether. — H. M. Hallett, 64, Westbourne Road, Penarth : April 17th, 1914. 



Note on Mysia oblongo-guttata, L., ab. nigroguttata, Dollm. — In 1912 I 

 recorded (Ent. Mo. Mag., xlviii, p. 215), the breeding of Syrphus torvus, O.-S., 

 from larvse found on some young pines in this district. Dtxring the past month 

 the same pines have been examined from time to time, and amongst the 

 Syrphid larva and imaginal and larval Coccinellids to be seen attendant upon 

 the very numeimis Aphides (Chermes) I noticed, on different occasions, three 

 freshly-emerged specimens of Mysia oblongo-guttata, L., one of which matched 

 Dollman's figure of his ab. nigroguttata* These immature examples were kept 

 alive with living Chermes for a week or so, but all died without maturing. It 

 will be found, I think, that this aberration will only be found amongst immature 

 examples in which the whitish pigment has incompletely filled the usual dorsal 

 giittse of the elytra, and the absence of it causes a certain amount of discolora- 

 tion or transparency, thus giving the appearance of dark spots. In one of the 

 three examples mentioned the right elytron only has a single dark dorsal 

 marking of this kind. Amongst the eight species of Coccinellids seen on these 

 particular pines, Exochomus 4-pustulatus was as common as Adalia bipunctata. —

Pygolampis bidentata, Goeze, in the New Forest. — Mr. W. West, of Lewisham, 

 has shown me a specimen of this rare Hemipteron, which he had the good 

 fortune to capture in the New Forest on May 22nd. This is one of the 

 most interesting captures of recent years, as it provides the second recorded 

 British example of a species which seemed to be hopelessly lost. As stated in 

 Douglas and Scott's " British Hemiptera," the first specimen was taken by 

 Mr. Thomas Marshall, of Leicester, about 30 years before the publication 

 of that work, and therefore about 80 years ago from the present date. It 

 was found in September under a piece of sandstone at Quatford, near Bridg- 

 north, Salop. Mr. West's specimen, which is a $ , was taken by sweeping on the 

 railway bank between Brockenhurst and Beaulieu Road Station. This insect 



* Ent. Record, 1912, pi. II. The reference to the description (p. 53) is not included in the 

 Special Index for that year, and the name therefore is likely to be overlooked.
