to C. vulgaris, from which it can at once be separated bj the form of the third caibital 

 cellule, and the partially black neuration, &c. It is apparently inodorous.— R. 

 McLachian, Lewisham : 2nd August, 1878. 



Potamanthus luteus at Weyhridge. — On the 6th of last month (July) , I captured 

 a large ? imago of this Ephemeron close to the mouth of the Wey. With the ex- 

 ception of a c? in my collection, a very old specimen obtained by me years ago (from 

 a source I cannot now trace), the species has been only known as Bi'itish by a sub- 

 imago described by Curtis, in 1834, as Baetis mellea, for which he gave no locality. 

 A recent capture (with a definite locality) is worthy of record. — Id. 



Cordulia Curtisi hi Hampshire. — On the 1st July last, I caught six specimens 

 (2 c? , 4 $ ) of this handsome species on a heath lying to the north of Pokesdown, 

 near Christchurch, Hants. As I understand from Mr. McLachian that he is not 

 aware of any specimens of this local species having been caught in this country for 

 many years, my captures may, possibly, be considered worth recording. — H. Goss, 

 Surbiton Hill : 17tk Avgust, 1878. 



[This insect (now known as Oxygadra Curtisi) used to be taken not uncommonly 

 in the New Forest Disti-ict by the late Messrs. Dale and Curtis. Probably it may 

 have been found continuously since, but I know of no recent records of its capture. 

 On the Continent, it has been found in France up to as far north as Le Mans (lat. 

 48°), but is essentially southern and western, occurring only in the south of England, 

 southern and western France, and in Spain and Portugal. — E. McLachlan]. 



Note on Trioza galii. — The sallow-pit at Lee, which, during the last thirty years, 

 has afforded more rare species of Lepidoptera, Coleoptera, and Hemiptera than any 

 other place of the same small extent in the kingdom, still exists, in spite of the near 

 approach of houses, and its productions are not yet exhausted. On the 1st inst., 

 from Galium uliginosu7n, which grows sparingly among the sallow-bushes, and also 

 in the open part among the rushes,* I beat some twenty examples of the hitherto 

 scarce Trioza galii into an umbrella, where they walked leisurely about, as though 

 the domain were tlieir own, not jumping except on persuasion ; yet, on the other 

 hand, one individual of a more venturesome or restless disposition flew down among 

 his quieter relations. Even on the dark-coloured nmbrella these black creatures, 

 looking very like Aphides, were rendered conspicuous by their lustre, and by the snow- 

 white band and spot on tlie abdomen. These latter are mentioned only by Flor, not 

 by Foerster, the original describer, nor by others ; and supposing the latter had to 

 deal only with dry insects it may have been that in the process of drying the white 

 markings wei'e retracted under the preceding segments and thus became invisible. f 

 Yet it should be remembered that Foerster had taken the species liimself, and must, 

 therefore, have seen the white markings noticed by Flor, which show through the 

 closed wings, if tliey existed on his examples ; further, that Foerster's species was 

 found on Galium verum, which grows only in dry places, while Flor's species was 



* Galium paluaire also straggles \ip among the herbage under the bushes, and I am not sure 

 that some of my captures did not come fiom it. 



t Flor considers that these markings are of the nature of a secretion, but does not say they are 

 evanescent : they are always regular in form.
