Insects. 



pleted with the second production of ova. I will just recapitulate the experiments 

 with P. palpina and N. dicteea, showing the two cycles, taking the dates roughly. 

 Larva fed up September, 1857 ; pupse remained through the winter ; moths emerged 

 in May, 1858 ; these laid eggs which hatched in June and proved fertile : this forms 

 the first cycle. Larva began to feed in June and buried at the end of that month and 

 early in J uly ; moths appeared about the beginning of August ; eggs from these hatched 

 in about ten days: this completes the second cycle, and here ended the experiments. 

 I may add that the larvae from these duly fed up, and the pupae of both P. palpina and 

 N. dictsea are now taking their winter repose. — G, Gascoyne ; Newark, November 4,

[Invited by Mr. Gascoyne to enter into further explanations, it is from no want of 

 courtesy that I decline, but simply because 1 possess no additional facts to lay before 

 my readers: ray interpretation of Mr. Gascoyne's views may have been erroneous ; at 

 any rate he is their best interpreter. One word as to " exceptional" summers, the 

 term applies equally to 1857 and 1858 ; in both the temperature was " exceptionally" 

 high. — Edward Newman^ 



Occurrence of Glcea erylhrocephala on the South Coast. — My friend Mr. Wright 

 has just brought to this office a specimen of this rarity, taken last night by himself at 

 sugar on the south coast ; two others were taken by a companion at the same time and 

 place. — Edward Newman ; November 2, 1858. 



Occurrence of Cam-ptogramma fluviata near Worthing. — I captured a splendid male 

 of this insect, in the middle of October, near Worthing, Sussex. It seems to be a 

 widely distributed species, and to occur throughout the summer and autumn months.

A new Nepticula. — There is a species of Nepticula now in the larva state in apple- 

 leaves, which I have repeatedly met with and reared. It does not seem to be as yet 

 described ; a brief account of it may therefore be interesting, and I would propose the 

 name Pomella. The egg is deposited on the under side of apple-leaves ; the larva, when 

 hatched, mines in the upper cuticle, and usually in the direction of the stem, forming a 

 slender track, which turns pink, and betrays the presence of a larva in the leaf before it 

 is visible to the naked eye ; this track is frequently close to a rib ; as the mine becomes 

 wider it is orange-coloured, with irregular tracks of brownish excrement : it is never 

 very conspicuous from above, but quite invisible on the under side; after a time the 

 larva commonly doubles on its track, and forms a blotch, from which it emerges on 

 the upper side to wander away and form its cocoon. The larva is very shining, orange- 

 coloured, with dorsal vessel only slightly darker ; head pale chestnut. The cocoon 

 varies from dark chestnut to bright orange: it is slightly mussel-shaped, and always 

 has a rim of much brighter hue round the upper end, which gives it a striking appear- 

 ance ; the pupa is protruded on the escape of the perfect insect. The imago expands 

 about three lines, and is of the unicolorous group ; the anterior wings cinereous, glossy, 

 and with a purple hue, brightest towards the apex ; the posterior wings of an uniform 

 paler colour; head rufous with whitish eye-caps. In the perfect slate it is closely 

 allied to N. pygmaeella. It is double-brooded, appearing in May and August, the larva 

 occurring in July, October and November ; the July larva seems very scarce, — I 

 observed them this July for the first time ; the autumnal larvas are by no means rare 

 in the neighbourhood of Bristol. — P. H.Vaughan ; Redlands, Bristol, October 29, 1858.
