species wlien really alarmed (see Ent. Weekly Intelligencer, vol. iv, p. 124). I have 

 noticed the same habit on another occasion. — W. H. Tugwell, 6, Lewisham Eoad, 

 Lewisham, S.E. : July \Mh, 1895. 



Boarmia ahietaria and Dicranura bicuspis at Plymoutk. — On July 7lh, 1891, 1 

 took a fine male Boarmia abietaria at rest on a larch tree in Biekleigh Vale ; also 

 on August 13tli, 189-1, three larvae of Dicranura bicuspis feeding on alder in the 

 Walkham Valley, of which one safely reached the imago stage as a male on May 26th, 

 1895. — H. W. Basden Smith, 6, Hillsborough, Plymouth : July 26lh, 1895. 



Colias Edusa at Tonbridge. — To-day (August 1st) I caught a very fine $ Colias 

 Edusa, it was an exceedingly fresh specimen. It has a rather deep black border, 

 with the nervures at the edge of the wing distinctly marked out in yellow, and the 

 whole border sprinkled with minute yellow dots rather more profusely than in most 

 specimens I have seen. — P. L. Babington, Walmer House, Tonbridge : August \st, 

 1895. 



Extraordinary aberrations in Lepidoptera. — In the course of a recent visit to 

 Liverpool, when, as usual, spending much pleasant time with Mr. S. J. Capper and 

 his fine collection of Lepidoptera, I examined two aberrations of so extraordinary a 

 character that I cannot pass them by without special notice. 



One is a male Zygcena lonicercB. On the right side it is nearly nonnal, the 

 hind-wing being a little shortened and quite pointed ; while on the left the hind- 

 wing is simply a duplicate of the fore-wing, being very nearly of equal length and 

 liaving the same rich blue-green colour and red spots. The only respects in which 

 it differs at all from the fore-wing on the same side is that the apex is slightly more 

 rounded, and the base of the costal margin is somewhat arched instead of straight. 

 The specimen is very perfect and beautiful, and presents an extraordinary appearance. 



The other is a gynandrous Lasiocampa quercus, var. calluncB. The left side is 

 male, of the usual rich, glossy, dark chocolate, with the ordinary orange-yellow 

 stripes, but the antenna on this side is provided with pectinations only one half the 

 usual length ; the right side is female with ordinary female antenna, and decidedly 

 larger fore- and hind-wings, but the colour is also rich chocolate, not quite so deep 

 nor so glossy as on the male side, but of a very rich colour, while the yellow stripe 

 though present on the fore-wing is absent from the hind, producing altogether a 

 novel and startling effect. The abdomen of this specimen is much shrunk and 

 twisted, and divided in sex, a clasper being clearly visible on the male side. Both 

 specimens were obtained from Yorkshire. — CuAS. G. Baukett, 39, Linden Grove, 

 Nunhead, S.E. : August, 1895. 



British locality for so-called Solenobia triquetrella. — In his most interesting 



notice of the occurrence in Britain of Solenobia TVockii, my friend Mr. C. G. 



Barrett {ante p. 164) says, " For many years we have heard nothing of the cases 



which he [Edleston — E. R. B.] used to find on large stones of millstone grit on the 



moors (in North Wales?), which were understood to produce S. triquetrella . . . ," 



but from the following evidence I think it is quite clear that the cases in question 



used to be collected, not in North Wales, but in Lancashire.
