Museum from Mergo in Uganda. There were with it in the same tube one small 

 and two large Workers, which he thought would probably be the means of identify- 

 ing the species at some future time. The Workers closely resembled specimens in 

 the Museum named D. arcenx, which is said to be the same as nigi-icanx. The 

 Rev. F. E. Lowe, various aberrant forms of Swiss butterflies, including Melanargia 

 galatea, ab. fulvata, Lowe, from Martigny ; Lyciena arion, ab., from Pontresina, 

 with the black spots on the under-side of the wings almost entirely absent, save one 

 very large kidney-shaped, slightly tinged with white at the centre of each wing ; 

 and a pair of Pieris napi, var. bri/onis-, taken in cop. at Caux, the $ not only 

 suffused as in hryonise, but also having the ¥ markings. Colonel Charles T. 

 Bingham, tlie pupa of a Tineid moth, probably of the genus Binsitta, from Upper 

 Burmah, presenting with its surroundings a remarkable mimetic resemblance to the 

 head and body of a small snake ; and a case illustrating the curious habits of 

 butterflies of the genera of Gerydus and Allotintif, which join with ants in attending 

 Aphidx for the sake of their sweet excretions. TJie Rev. F. D. Morice, a very 

 remarkable gynandromorphous specimen from Silchester of the common fern- 

 visiting Saw-fly, which, originally described by Fabricius as Kylotoma cingulata, 

 was generally known afterwards as Tenthredo cingulaia, and is now called — the 

 generic name being Dahlbom's — Strong ylog aster cingulatus, F., the dividing line 

 between the (J and ? portions running longitudinally, not transversely, from end to 

 end of the creature ; a form stated by the President to be unique. Mr. Percy I. 

 Lathy communicated " Notes on the Indo-Australian Papilionids?," and Mr. Ernest 

 A. Elliott and Mr. Claude Morley "On the Hymenopterous Parasites of Coleoptera."

In the history of British Entomology during the second quarter 

 of the nineteenth century, three names— those of James Francis 

 Stephens, John Curtis, and James Charles Dale — stand pre-eminent; 

 and the great collections of all Orders of our indigenous insects, 

 formed by these pioneers of our Science, fortunately still exist in their 

 entirety. One of these, that of John Curtis, is now at the Antipodes, 

 and thus no longer within our reach, but Stephens's insects have long 

 formed a valuable item in our National Collection ; and within the 

 last few months, the extensive collections commenced by the elder 

 Dale in the opening years of the last century, and since his decease 

 in 1872, continued and augmented by his son, have through the 

 munificence of the last-named Entomologist, found a final and per-
