Trichopteryx Lmtitice, Matt. — a species new to Britain; with notes on other 

 TrichopterygidcB. — Among a number of Trichopterygia, which I sent to tlie Rev. A. 

 Matthews for identification a short time ago, were several examples of a species new 

 to Britain, viz. : — T. Lcetitice, Matt., — a full description of which is given by Mr. 

 Matthews in the Ent. Mo. Mag., vol. ix, p. 180. It is allied to T.fascicularis, Herbst, 

 but difPers from it in its smaller and more depressed thorax, shorter and pitchy-black 

 antennae, and in its conspicuously smaller size. It was first found in large numbers, 

 unmixed with any other form, by Miss L. Matthews (after whom the species is named) 

 near Spa, in Belgium. I found it by shaking rushes at the side of a pond in Robin's 

 Wood, near Repton, Burton-on-Trent, in May last, and have taken altogether about 

 forty specimens. In company with it I took T. atomaria, De Gr., T.fascicularis, 

 Herbst, and T. lata, Mots., and one specimen of the rare T. cantiana. Matt. 



I have also taken the following quite recently in the neighbourhood of Repton, 

 the best of them being from the hot-bed in my own garden : T. sericans, Heer (very 

 abundant) ; T. anthracina. Matt, (in some numbers) ; T. grandicollis, Mann. ; T. 

 hovina, Mots.; T. Montandoni, All.; T. longula, Matt, (four specimens) ; T. thoracia. 

 Grill, (two specimens) ; and T. hrevis. Mots, (two specimens) : Ptilium Spencei, All., and 

 trisulcatmii, Aahe ; Ptenidium etanescens, Marsh, {apicale, Er.), and»/^J(iMHt, Heer. 



Concerning T. hrevis, Mr. Matthews writes to me as follows : " of the last men- 

 " tioned I do not remember ever having seen a British example, except those which 

 " I or my brother liave taken : one of your specimens is a very remarkable variety : 

 " it has four very distinct foveolate depressions on the thorax, but among the Trichop- 

 " terygia such markings are by no means conclusive specific distinctions, especially 

 " when the normal structure is uninterrupted : I have specimens of T. brevipennis 

 " and Ptinella testacea, which exhibit depressions of a similar kind." T. longula 

 and T. cantiana are species which have been comparatively recently discovered, 

 neither of them appears in Dr. Sharp's catalogue. The fact of so many good species 

 being taken in one very small district in the heart of the Midlands, shows us how 

 much there yet remains to be done in this interesting group, which is so often 

 entirely neglected by collectors. 



I ought to add that the whole of the species above mentioned are given on the 

 authority of Mr. Matthews, to whom I am exceedingly indebted for his kind help, 

 without which I am afraid my names would have been anything but authentic. — W. 

 W. Fowler, Repton, Burton-on-Trent : October 13th, 1879. 



Singular occurrence in a dipterous insect — In the Ent. Mo. Mag., vol. ix, p. 46, 

 Mr. Dale records a case of double coition in a Molobrns ; and asks if any one has 

 ever before noticed a similar instance. To this the editors append a note, that 

 they do not remember records of this anomaly concerning the Diptera, though 

 it has several times been noticed in other Orders. 



I can give another example in the Diptera. In my Jamaica MS. Journals I find 

 the following, which I have never before published : — 



" October 15th, 1845. — I observed a most extraordinary thing. Two males of a 

 " small species of Bibio (?) were in copuld with one female at the same time, both 

 " equally firmly fastened." I have added, in my Journal, a pen-and-ink sketch of 

 the insects, by which the males are represented as "15 inch, the female "2 inch in 

 length. The specimens I did not preserve. — P. H. Gtosse, Sandhurst, Torquay ; 

 October, 1879.
