any of these species from the northern counties of England and from 

 any part of Scotland. — J. W. Tutt. Novcuiber 2Qth, 1901. 



Hybrid Smerinthus ocellatusc? X S. populi $ . — On the morning 

 of June 4th I found a &neS S. ocellatits paired Avith a large $ S. popiili 

 in one of my cages, the specimens stayed in cop. till dusk, when I placed 

 the 2 S. ])opidi in a large muslin-covered box. She started to lay at once, 

 her ova were not scattered but laid in large batches all stuck together ; 

 one batch consisted of 43 eggs, and, in all, 135 ova were laid. These were 

 watched carefully, and, on June 15th, I was delighted to see three young 

 larvae. All the ova were immediately sleeved on black Italian poplar, 

 but only 45 emerged, the others did not appear to be able to break the 

 shell ; all went well, and I reared the 45 to the pupal state (at least 

 twelve of them were sent away as full-fed larvfe, and I heard that they 

 pupated satisfactorily). The larvte were very variable. On looking at them 

 in the sleeve one would have supposed there were larvae of S. pnpuli and 

 S. occllatus mixed, some were very pale green with a blue horn, while 

 others were of a dark vivid green, exactly like -S'. pnpuli ; but what struck 

 me particularly was that the larva of pale green hue were in shape 

 precisely like those of S. ocellatns, and those of the dark green colour 

 exactly like larvae of S. jmpuU. All the pupse were alike — S. ocellatus 

 in shape with the roughness of S. popnli. I do not possess these pupa 

 now, but I feel sure that some of our leading collectors will describe 

 the imagines when they emerge. — L. W. Newman, Bexley, Kent. 



A NEW British flea. — In the Fhitoiiioloi/isfs Becnrd, vol. xii., p. 

 19 (1900), I recorded Ti/jihlopHijlla oncntaliii, Wagner, as a British 

 species. The insect referred to is really Tupldopanlla hisFtejiteiinlenfata, 

 Kol. {cf. Wagner, Hur. Soc. Knt. Iloss., t. xxxv., p. 24, 1900), also a 

 species not previously recorded from the British Islands. — N. Charles 

 Rothschild, B.A., F.E.S., Tring Park, Tring.

Egg of Nepticula, sp. — While taking cases of ColeopJiora 

 liemcyohiella off a whitethorn at Putney, May 28th, 1901, about 

 4.30 p.m., I saw a Nepticulid alight on a whitethorn leaf. She ran 

 over the leaf in the warm sunshine, then, suddenly stopping, she 

 seemed to examine the leaf surface, and, as suddenly reversed her 

 position, bringing the abdomen to the spot where the head had been. 

 After remaining a second or two, as if ovipositing, she flew off before 

 I could box her. I picked the leaf, and, on examining the spot where 

 she had rested with a strong lens, found the egg. The moth was 

 black with an uneven fascia rather beyond the centre of the wing. I 

 fancy it was a specimen of Xcpticida atricollis. The egg, laid on the 

 underside of the leaf (this surface at the time being exposed to the 

 sun's rays), was situated in the angle between the lamina and the first 

 lateral rib, at its junction with the midrib. To the unaided eye the 

 ovum appeared as a minute dull white bead. Under the microscope 

 it was pale green, the surface reflecting the light but not glistening. 

 I believe the ovum itself was really almost colourless, the green tint 

 being due to the leaf. The ovum might be described as a globule of 

 transparent fluid enveloped in a delicate colourless collapsible skin, in 

 shape conforming more or less with its surroundings. In outline this 

 one was fairly circular, very flat, the height as compared with the
