The nodulated and netted top is comparatively flat, and the micro- 

 pylar area is in a shallow central hollow. In colour the egg is whitish, 

 but has about five dark spots in each hollow between the ribs, they are 

 not very regular in disposition, size, or outline, each consisting of an 

 aggregation of a number of very small spots. Similar spots occur on 



Camera sketches of egg. Pig. 1 shows ribbing and general form ; Fig. 2 

 ■gives something of the size and disposition of the dark markings ; Fig.'s shows 

 the knots and ribbing of the summit; and Fig. 4 the arrangement 'of cells in the 

 micropylar area. 



the top, one occupying the micropylar hollow, the others are smaller 

 than the lateral ones, they are not very regularly placed and look a 

 little ragged from their constituent dots not being very closely aggre- 

 gated. This description applies to two of the eggs, a third looks 

 darker, the spots being larger in this one, and one of the ribs does not 

 reach so high as the others. 



On August 29th, the larvae within having become well-developed 

 the eggs are of a somewhat uniform pale leaden tint, except that the 

 ribs stand out white (really colourless), the contents having left them 

 vacant. 



The larvaa hatched on August 31st. During and just after hatch- 

 ing the larvffi eat the whole of the egg-shell. 



The newly hatched larva is about l-5mm. long, of a pale leaden 

 ochreous colour, the head brighter, almost yellow, about 0'75mm. 

 across, the body being about 0-5mm. The head (figs. 7 and 8) is very 

 rounded, has a very fine sculpturing, in fact much resembling that on 

 some Lycaenid eggs, the hollows very irregular in shape and arran ce- 

 ment, but of nearly uniform size, something rather less than 0'02mm, 

 in diameter. There are on the head some hairs, five or six being visible 

 on either side on a front view. These are longer, straiohter, and 

 smoother than those on the body (about 0-04mm.), more lik^e ordinary 

 hairs, but a little curved. On or near the clypeus, however, they are 

 longer (0-lmm.) and more numerous, two hairs being towards the apex 

 of the clypeus. On the cranium they are a little clubbed and well- ser- 

 rated. The skin of the larva is rough with fine points ; there are the 

 usual tubercles on the abdomen, of the two subspiraculars the anterior is 

 much the lowest. The tubercles have raised, almost globular or urn- 

 shaped, bases, with a dark ring at the top. The hairs themselves are
