The Zoologist— January, 1866. 8 



a coloured drawing, by Mr. Buckler, of the larva, which, as well as the imago, differed 

 from those of the other species mentioned. This new insect had been both captured 

 and bred at Manchester and Sheffield ; in this case also the larvae fed on Polygonum 

 aviculare, a plant which appeared to be very generally acceptable to the larvae of Geo- 

 raetr*. 



Mr. Bond also exhibited a number of admirable photographs, by Dr. Maddox, of 

 microscopic objects, e.g., the leaf insect of the sycamore, the Acarus of the fig, para- 

 sites of the field-mouse, the mole, the sparrow, the chaffinch, &c. 



Mr. M'Lachlan exhibited a partially andromorphous female of the dragon-fly, 

 Calepteryx splendens ; the left anterior wing was in colour precisely like that of a 

 male, but retained the female form of wing ; the right anterior wing had only blotches 

 or dashes of the dark male colouring on the dorsal portion of the wing ; the specimen 

 was captured in France by M. Fallou, of Paris. De Selys Longchamps mentioned 

 the capture, in Prussia, by Dr. Hagen, of a female C. splendens the wings of which 

 were entirely coloured as in the male. 



Mr. Janson exhibited Myrmedonia plicata, iJnc^., a species new to Britain: a 

 dozen specimens had been captured at Bournemouth in August last, by Messrs. E. A. 

 and Edgar Smith ; they were found on an open heath, at the roots of grass, amongst 

 which was a nest of the ant, Tapinoma erratica. Mr. Janson remarked that the pre- 

 sence, in all the twelve specimens, of the curious conformation of the dorsal surface of 

 the fourth and fifth abdominal segments rendered it probable that this slructure was 

 common to the two sexes, and was not peculiar to the male of Myrmedonia, as had 

 hilherlo been supposed. 



Mr. G. R. Crotch exhibited ^gialia rufa. Fair., Erich, a species new to Britain, 

 of which several specimens were taken at Liverpool by Mr. F. Archer, but, with the 

 exception of that exhibited, had been accidentally destroyed ; also Lithocharis castanea, 

 Grav., Erich., which is the Medou Ruddii, Sleph., whilst the species from the Isle of 

 Wight which is in many of our collections appears to be the L. maritima, Auhe 

 (Grenier, Cat. Col. Fr.); also Monotoma 4-fuveolata, Auhi, of which three or four 

 specimens were formerly taken by Mr. Janson in Hainault Forest, and which was 

 readily distinguished from all the other species by its thoracic foveae ; this name was 

 introduced into the British list by Mr. Waterhouse, but afterwards withdrawn, his 

 insect proving to be M. rufa, Redl. 



Mr. S. Stevens exhibited a box of insects of all orders, being a further portion of 

 the collection made by Mr. Audersson in Damara-land. Amongst them were Goliathus 

 Layardi, Eurymorpha Mouffleti, F. (cyanipes, Hope), an Atractosomus, &c. ; and a new 

 species of Acrcea from the Victoria Falls, Zambesi. 



Mr. S. Stevens also exhibited a number of oak-spangles, the work of Cynips 

 longipennis, which had recently been found in profusion by Mr. Hevvitscm at Oat- 

 lands. 



Mr. S. Stevens announced the death of Mr. P. Bouchard at Santa Martha, whither 

 he had gone to collect; and read a letter from Mr. Plant, dated Tamatavi, September 

 2, 1865, in which the writer recounted some of his entomological experiences in Mada- 

 gascar. 



The President called attention to the account published in that morning's news- 

 papers of the wreck of the " Duncan Dunbar " on the reef Las Roccas, in long. 33° 45' 

 W., and lal. 3*" 52' S., on the 7th of October. The vessel struck the reef at high waterj
