" 3. Psychomia (Horaoecerus) derelicta (n. s.). I propose this name for an insect 

 belonging to a rather obscure group, and which I cannot make out to have been pre- 

 viously described ; a specimen sent to Dr. Hagen last year was returned as unknown 

 to him. It belongs to a group mentioned by Dr. Hagen in the ' Stelliner Enlomolo- 

 gische Zeitung' for 1860, p. 279, differing from the true Psychomiae in the broader 

 and more obtuse wings, in the more widely dilated intermediate legs of the female, 

 and especially in the possession by that sex of a rather long and curved ovipositor ; 

 nevertheless Dr. Hagen thinks that the proper place of the group is with Psj'chomia. 

 Kolenati, in the second part of the ' Genera et Species Trichopterorum,' places it as a 

 subgenus of Tinodes, which he calls Homoecerus, a position it can scarcely retain, as the 

 females of Tinodes have undilated intermediate legs. Kolenati describes four species under 

 the names of (1) albipunctatus, Steph., known to him only from description ; the type 

 of Stephens' species is a small Hydropsyche ; (2) obscurus, Steph., which cannot be 

 Stephens' species, the type of which is a female of Glossosoma fimbriata, Steph. ; (3) 

 affinis, Kolenati, a new species, differing in the venation of the under wings; and (4) 

 pusilla, Fabricius, of which I may say that what Fabricius' species really is must, I 

 think, always remain conjectural : pusilla, Stephens, is a true Psychomia, and the same 

 as his phseopa ; pusilla, Curtis, is a small True Tinodes. 



" I have drawn up the following diagnosis of the new species. 



" Psychomia (Homoecerus) derelicta. 



" Nigro-fusca ; antennis saturate brunneis, testaceo annulatis; palpis brunneis; 

 capite thorace abdomineque nigro-fuscis; oviducto testaceo-fusco, sursum incur- 

 vato ; pedibus fuscis, vix testaceis ; alls anticls fuligineo-fuscis, vix iridescenti- 

 bus, dense pilosis; posticis fusco hyalinis. {Fcem). 



" Long. corp. If lin.; exp. al. 5 — 6 lin. 



" Of this I have seen five specimens, all of which are females. It has been taken 

 by Mr. Parfitt near Exeter, by Mr. Fenn at Wallingford, by Mr. Barrett at Haslemere, 

 in July, and by myself near Kew, in August. It is larger and darker than the other 

 described species." 



Mr. Stainton exhibited specimens of Tinea vivipara,' Scott, and read the following 

 notice of the habits of that species : — 



" This insect has been described in the first part of the ' Transactions of the Ento- 

 mological Society of New South Wales,' by the Hon. A. W. Scott, of Ash Island, 

 Hexham, which is about seventy-five miles N.N.E. of Sydney. The specimens exhi- 

 bited were captured by Mr. Diggles at Moreton Bay, which is three hundred miles 

 further to the north. Its beauty is not the only interest which this elegant species 

 possesses, for it appears from the observations of Mr. Scott that the females do not 

 deposit eggs, but living larvae. 



" 'It was after dark, in the early part of the month of October, 1861, that we first 

 captured a specimen with the hand, being attracted at the moment by its elegant 

 colouring, and wishing to secure it for the cabinet. Fearful that the plumage might 

 be injured by the struggles of the moth while endeavouring to escape, it was gently 

 compressed, and on opening the hand we observed numbers of minute but perfect larvae 

 being ejected from the abdomen in rapid succession, and moving about with consider- 

 able celerity, evidently in search of suitable shelter and food. This incident, so singular
