insect being in perfect condition, and presenting no indication of the 
peculiarity having been induced by artificial means. 
Mr. Howard Vaughan exhibited examples of the Triphzna from Forres, 
captured by Mr. G. Norman, which Mr. Newman had named T. Curtisii. 
Mr, Vaughan, however, considered it to be only a dark form of T. orbona. 
Mr. W. A. Lewis made some observations on the synonymy of this form, 
pointing out that it had been figured by Curtis.as T. consequa, Hiibner, and, 
further, that it was given by Stephens as T. subsequa, W. V. 
Mr. Vaughan also exhibited a nearly black variety of Arge Galathea, 
captured in Kent by Mr. Farn. 
Mr. E. W. Janson exhibited two new, or recently detected, species of 
Coleoptera, captured by the Rev. A. Matthews, as follows :-— 
‘“THROSCUS CARINIFRONS, de Bonvouloir, Essai Monographique sur la 
Famille des Throscides, p. 20, tab. i. fig. 5 (1859). 
« At first sight resembling T. dermestoides, L., but at once distinguished 
from it by the ocular depression extending right across the eyes; more 
nearly allied to T. elateroides, Heer (T. gracilis? Woll.), but readily sepa- 
rated therefrom by its superior size, the prominence of the lateral frontal 
longitudinal ridges, which extend to the anterior margin of the prothorax, 
the sinuated sides and prominent posterior angles of the prothorax, especially 
in the males, and the somewhat finer punctuation of the interstices of the 
elytra. 
«Three specimens taken by the Rev. A. Matthews, in company with 
T. dermestoides, by sweeping in a plantation near Chiselhurst, in July, 1869, 
and shortly after placed in my hands for identification. 2 
“ CRYPHALUS PICEH, Ratzeburg, Forst-Insecten, i. p. 163 (1837). 
« Allied to C. abietis, Ratzeb., but larger, less convex, the elevations on 
the anterior part of the prothorax larger and arranged in five or six tolerably 
regular rows, the striz of the elytra distinct, and the interstices, especially 
towards the apex, with sparse erect yellow bristles. 
“One specimen taken by the Rey. A. Matthews, many years since, in the 
vicinity of Weston, Oxon.” 
Mr. F. Smith exhibited a large Noctua, apparently an Aplecta, captured 
by Mr. J. Gwyn Jeffreys, on the Atlantic, about 220 miles from Nova 
Scotia, on the outward voyage. (This has since been identified as the pale 
form of Aplecta occulta). 
Mr. M‘Lachlan exhibited the remarkable wingless Californian Bittacus, 
recently described and figured by him in the ‘ Entomologist’s Monthly 
Magazine,’ vol. viii. pp. 100—102, as Bittacus apterus. 
Mr. Albert Miiller exhibited a gigantic Californian oak-gall, given to him 
by Mr. C. V. Riley, of St. Louis, Missouri. Also the impregnated and un- 
impregnated eggs of Libellula flaveola, Linné, the former being whitish in
