356 THE entomologist's eecord. 



general average of representation should if possible be devised. It is 

 perhaps worthy of note that the average attendance at the meetings 

 always appears to be higher when a lepidopterist is in the chair, and 

 record meetings generally occur when Mr. Merrifield, Mr. Elwes, Dr. 

 Dixey, Professor Poulton, or some well-known lepidopterist is on the 

 warpath. The friendly selection of a long list of well-known Fellows 

 by outsiders, that might be added to the list chosen by the Council, 

 in order to obtain a popular election at the next general meeting 

 might perhaps prove a step in the right direction.

Eggs of Lepidoptera. — Enbolia pliuiibaria. — Length -TSmm., 

 width -gmm., height about •25mm., oval in outline with a deep oval 

 depression occupying almost the whole of the upper surface, pale 

 yellow in colour, covered with a reticu.lation of large polygons 

 (chiefly hexagonal) the lines of the network not very coarse. The 

 base of the egg is equally reticulated with the sides, but the mesh of 

 the reticulation becomes much smaller around the micropyle, which is 

 placed centrally at one end, and consists of a stella of small radiating 

 cells (Described July 20th, 1898, from eggs sent by Mr. Clutten). 



Callvjenia miniata. — Eggs laid on July 27th, 1898, at Aix-les- 

 Bains, matured very rapidly, and by August 3rd were grey in colour, 

 with the upper parts blackish-grey. This dark part under a lens 

 proved to be the heads of the contained embryos which were already 

 practically mature. The nine-pin-like appearance of the eggs of this 

 species has been already referred to. 



Mdampias epij^hron. — Pale yellow in colour ; tall compared with 

 width (3:2); the tranverse section circular ; about 14 or 15 ribs from 

 base, some not reaching the top, distinct, but not very sharp and no 

 great depth between them, transverse ribbing very indistinct, the 

 micropylar area flattened, the ribs appear to anastomose on the edge of 

 the micropylar area, which although flattened is not depressed ; base 

 smooth, its shape forms a truncated cone, with the apical diameter 

 almost as wide as the basal (Described August 12th, under hand 

 lens from egg laid August 11th, by ? caught on the slopes above Villa, 

 near Evolena, by Dr Chapman). 



Aciptiliatetradactijla. — Long axis horizontal, length : breadth : : 3 : 

 2 ; laid on lid of box ; pale-green in colour ; almost regularly oval in 

 outline, although rather broader at micropylar end ; somewhat plump, 

 surface apparently quite smooth, and no trace of a depression on 

 upper surface ; exceedingly minute, no means of judging size 

 (Described with hand lens, August 2nd, 1899, from eggs laid same 

 day by moth captured at Simplon) . 



Acidalia jiaveolaria. — Laid on its long side ; very pale brownish, 

 even when first laid, becoming slightly darker afterwards ; broadly 

 oval in outline ; length : breadth : : 5 : 4 ; the ends somewhat 

 flattened, one (micropylar) end appearing to be rather more so than the 

 other ; the upper surface slightly depressed, the whole surface covered 

 with a fine polygonal network arranged in longitudinal ovals, the reticu- 

 lation very marked (but not coarse as in A. humiliata), the hexagonal 

 spaces deep owing to height of ribs ; about eleven to width of egg and
