iag outline figures will serve to show the diversity whicli exists in the 

 cases of the British HydroptiUdcB. Figs. 3 and 4 represent respec- 

 tively the larval and nymph cases of the subject of the present notice ; 

 fig. 5, larval case of Oxyetliira costalis ; fig. 6, larval case of OrtJio- 

 trichia angusfella (?) ; and fig. 7, larval case of Agraylea muUipicnctata. 

 In addition to these, there is the case of the true Hydroptilce, more 

 or less reniform, and differing from the others in being covered with 

 minute grains of sand.

P.S, — I have just received the Entomol. ]S"achrichten for Novem- 

 ber, containing a paper by Dr. Fritz Miiller, entitled, " Eine deutsche 

 JJagenopsycJie,'" in which he describes a case at first referred to 

 Layenopsyclie (on account of its resemblance to Brazilian cases so 

 named by him), but now held by him to belong to OxyetJiira, and 

 probably to O. costalis. He does not appear to know that O. costalis 

 has been bred in this country, and the cases noticed by Mr. MeLachlan 

 and myself (Ent. Mo. Mag., vol. xxiii, pp. 17 and 201). In my notes 

 I quoted Miiller' s description of the case named Layenopsycke to give 

 a better idea of that of O. costalis ; he says that save in the matter of 

 colour, the description of the subject of his paper in the Entomol. 

 Nachriehten agrees word for word with that of the cases he formerly 

 named Lagenopsyche. Although Dr. Muller's figure differs from 

 mine slightly (the only case I have now is in balsam, and possibly 

 altered a little from pressure), I have no hesitation in referring it to 

 O. costalis.—^. J. M. 



Neuronia elatJirata, KoL, reported from the London District. — A sliort time 

 ago I noticed at Mr. Doncaster's in a box of miscellaneous and mostly very common 

 British insects, two very fine examples of this pretty and rare British caddis-fly. 

 The few British Bpecimena known to exist had come from certain woods in 

 Staffordshire and vicinity. I asked Mr. Doncaster to obtain further information as 

 to the locality of these two specimens. He says that all the insects in the box were 

 taken by Mr. Boden, a London collector, and the latter assures him the caddis-flies 

 were captured in the Tottenham Marshes some three years ago. Supposing no en-or 

 of memory to have occurred, this is very interesting. There is a parallel to it, for 

 the unique British example (now destroyed) of Af/rt/j^nia picta (a near relative of 

 Neuronia) was taken on a gas lamp at Highgate by Mr. H. Pryer, now of Japan, in 

 June, 1868 {cf. Ent. Mo. Mag., vol. v, pp. 125 and 143).— R. McLachiah",
