72 THE ENTOMOLOGIST. 



find insects attacked by mites (Acari) among their disused boxes, 

 would be willing to send him such insects, with the mites still on them 

 or accompanying them, or at least the mites themselves, with the 

 name of the insect given in all cases, for the purpose of his forth- 

 coming monograph of the Tyroglyphidse. Mr. J. W. Tutt showed a 

 fine series of forms of Hemerophila abruptaria, Thuub., captured and 

 bred by Mr. W. S. Pearce at Holloway, varying from the normal 

 colour, through mahogany-brown to dark fuscous, some of the speci- 

 mens of the second brood showing a purplish hue. One gynandro- 

 morphous example was shown, with the wings and right antenna of 

 the female type, the left antenna being strongly pectinated. He also 

 exhibited two specimens of Dianthcecia luteayo, bred by the Rev. F. 

 Lowe, from larvae obtained in Guernsey, and of a very distinct 

 character, having a tendency to the ochreous coloration of the type- 

 form, but being differently marked. On behalf of Mr. Heyne, 

 Mr. Jacoby exhibited a series of temperature-varieties of Lepidoptera. 

 Mr. G. H. Carpenter read a paper by himself and the Rev. W. F. 

 Johnson on " The Larva of Pelophila borealis," describing its structure 

 and life-history. On the larval characters the species, hitherto 

 considered as of doubtful relationship, was regarded as being closely 

 allied to Elaphrus. Papers were communicated by Mr. F. D. Godman, 

 F.R.S., and Mr. 0. Salvin, F.R.S., on " New Species of American 

 Rhopalocera," and by Mr. M. Jacoby, " On Some Phytophagous 

 Coleoptera (Euinolpidas) from the Islands of Mauritius and Reunion." 

 February 16th.— Mr. G. H. Verrall, Vice-President, in the chair. 

 Mr. G. C. Champion exhibited specimens of Isodermus <jayi, Spin., from 

 the Straits of Magellan, and I. planus, Er., from Tasmania, both found 

 by Mr. J. J. Walker. The genus Isoderma, belonging to the Aradida3, 

 afforded an interesting case of geographical distribution, the only 

 known species occurring in Chili, Australia, and Tasmania. Mr. C. 0. 

 Waterhouse referred to the similar distribution of other species 

 of insects, which went to support the theory of a former connection 

 between South America and Australia. Mr. Champion also showed 

 an example of Bayous lutosus, Gyll., from Sweden. This insect had 

 been on the British list since the time of Stephens, but possibly in 

 error, as all the examples he had seen in collections were wrongly so 

 named. Mr. Jacoby exhibited a pair of the singular weevil, Apoderus 

 tenuissimus, Pasc, from the Philippines. Mr. Burr exhibited species 

 of Orthoptera, of the family Eumastacidre, resembling dead leaves. 

 This was the only family of Acrydiidse in which such resemblances 

 were found. Dr. Chapman exhibited a specimen of Zyyceaa exulans 

 with six wings, the supernumerary pair arising between the normal left 

 fore wing and the corresponding leg on the same side. The upper- 

 most wing appeared normal in every respect, the second was a reduced 

 copy of the basal half of a fore wing, and the third a portion 

 of crumpled wing-structure. Mr. 0. E. Janson exhibited a pale 

 variety of the rare Papilio mikado taken in S. Japan. Mr. Tutt 

 showed a variety of tinodia hyperanthus taken by Mr. F. H. Day near 

 Carlisle, and banded on the under side like a Qomonympha ; also two 

 moths from the same neighbourhood, which, after careful comparison, 

 he regarded as females of Hydrilla palustris. This sex was almost or 

 quite undiscovered in Great Britain, and the occurrence of the species
