needless to say that I at once pounced upon a seedbead, on opening which a fine fat 

 reddish Ettpoecilla larva bustled out in great haste. Subsequent examination revealed 

 larvae of all sizes in these seedheads from the full-fed stage to mere babies, one head 

 often containing several larvse in various stages of growth. Owing to an accident 

 my own batch came to grief, but Messrs. E. R. Bank'es and W. H. B. Fletcher have' 

 been more successful, and have dOly bred several specimens of Eupcecilia pallidana 

 from these larvse this year, the imago emerging in June. — C. R. Digbt, Studland

The true position of the genus Chimarrha. — When making a critical examination! 

 of the pretty Chimarrha marginata, L., for my Revision and Synopsis of the European. 

 Trichoptera, certmn points in its structure induced me to hold grave doubts as to the 

 correctness of its position in the family Rhyacophilidce in which it had been placed 

 by Trichopterists, and in which I retained it provisionally. Dr. Fritz Miiller haa 

 just published (Entomologische Nachrichten, xiii, No. 15, -Aug., 1887) notes on a 

 Brazilian species of Chimarrha which tend to prove that the genus should really be 

 placed in the Hydropsychidce, which accords with my own idea suggested in 1879. 

 He found a pupa in a fixed case of small stones attached to a larger stone, and bred 

 therefrom a Chimarrha. He urges that the case belonged to the Hydropsychida 

 because its fixed side was closed by a web which is absent in the otherwise very 

 similar cases of RhyacophilidcB, and, as I read his remarks, there was no special inner 

 pupal cocoon* (which exists in Rhyacophilidce) . For some other interesting details 

 I refer the reader to Dr. Miiller's original remarks. He ofPers no opinion on the, 

 condition of the terminal joint of the maxillary palpi, which, in the Hydropsychida, 

 is multi -articulate, or, at any rate, with a semblance of being formed of more or less 

 numerous small joints, a poirt on which I could not satisfy myself in 1879, so far as 

 Chimarrha was concerned. But I think we may now assume that the genus belongs 

 to the Hydropsychidce, a change that will not alter its sequential position in my 

 European arrangement, where it immediately follows that family, heading the 

 RhyacophilidcB as a special " Section." As Ch. marginata is usually very abundant 

 where it occurs, there should be no difficulty in finding its larva, and Dr. Miiller's 

 remarks furnish a clue. — R. McLachlan, Lewisham : August 6th, 1887. 



Concerning TcBniopteryx maracandica, McLach. — Having been attempting 

 to-day to effect a provisional re-arrangement of some of my smaller Perlidce of the 

 European Fauna, which had fallen into a chaotic condition, and being occupied with 

 the genus TcBniopteryx, I had occasion to re-examine T. maracandica, McLach., 

 from Turkestan, described (and wing figured) in the Neuroptera of Fedtschenko's 

 Travels in Turkestan, p. 34, pi. iv. (1875). The insect resembles a TcBniopteryx in 

 its elongate form, and even the neuratiou is not distinctly opposed to its position in 

 that genus ; but I find the second joint of the tarsi is very short, and as Pictet 

 makes this one of the essential characters in separating Tceniopteryx (in which all 

 three joints are long) from Nemoura (in which the middle joint is very short), I think 

 it will be better to transfer T. maracandica to the genus Nemoura. On parallel 

 grounds Pictet retains monilicornis (not personally known to me) in Tceniopteryx, 

 although its neuration (as figured) does dot appear to differ from that of Leuctra. — '
