78 THE entomologist's record. 



I'eujai'kably small and elementary, closely resetubling those of the 

 Toi'ti'icids, Adelids, and (Ecophorids. Its shape is a very irregular 

 oval, tapering slightly towards the micropylar end. In colour it is 

 yellowish-salmon, brightening to light cream at the luicropylar end. 

 It is flaccid, irregular, with shining surface irregularly divided into 

 -i-, 5-, or 6-sided polygons by fairly sharp ribbing. This ribbing, how- 

 ever, becomes smoother and more curvilinear towards the thick end of 

 the egg, and finally vanishes. Towards the micropylar end fifteen 

 cells come up to the stellate area (the area immediately round the 

 micropyle). This area is itself very irregular, and consists of two 

 much-broken rings of polygonal cells marked out by semi-transparent 

 ribs, which thicken externally, and gradually pass into the ordinary 

 cells of the body of the egg. The micropyle is also very irregular and 

 remarkably small, even smaller than one of the average cells on the 

 body of the egg. The outline of each cell of the rosette which forms 

 the micropyle is more rectilinear than is the case in more advanced 

 groups, which gives these cells a triangular appearance. These cells 

 usually number fourteen, but are sometimes irregularly combined in 

 pairs so as to give the appearance, under low power, of being only 

 seven in number. The ribbed margins of these cells meet at the very 

 centre of the micropyle, and form a conspicuous crater. The following 

 are the measurements of the different parts of the egg : — Total length 

 l-282mm, Total breadth (a) at centre •74mm.; (b) at rounded end 

 •74mm.; (t) at micropylar end .54mm. Diameter of stellate area 

 •154mm. The micropylar measurements made in micro-millimetres 

 (10000/Aft. = Imin.) are as follows: Micropyle — greatest diameter 

 51*5)U.ju,., shortest diameter 48-5)a/i.., longest petal 25/x/a., shortest petal 

 12'5/x;u,., central crater 9"3/a/x. The average size of diameter of cell on 

 body of egg is 65^3/i,|U,. [Described under ^" objective lens with 27"

Larva of Brenthis thore at hibernating stage. — The larva is 

 in this stage 5mm. long, a little retracted, can vary from 4mm. to 

 6^5mm. ; when contracted looks very short and thick, the approxima- 

 tion of spines and hairs making them seem part of the solid larva. 

 Colour black, with a row of subdorsal yellow marks. There are three 

 rows of spines down each side, and the yellow marks are between the 

 1st and 2nd rows (1st row of spines being the subdorsal one, 3rd mar- 

 ginal). The marks occur two on prothorax, one each on meso- and meta- 

 thorax, and one each on 2nd, 4th, 6th, and <Sth abdominals. The thoracics 

 are small and, whitish (very faint lemon-yellow), those on the abdomen 

 are largest in front, and are almost orange, and each has a depressed or 

 dark dot centrally, legs black, prolegs with the soft part greenish-grey. 

 A careful examination of the spines and tubercles shows that they are 

 tall pyramidal horns or warts clothed with eight or ten bristles, 

 each on its own separate raised conical base, and with one, little 

 larger than the others, as a terminal spine. Then there are lower 

 raised bosses with hairs (Arctiid in character), and further hairs 

 separate from the warts that might be secondary tubercles or merely 

 skin-hairs. The tall horns are — first a subdorsal one, that appears to 

 be i + ii conjoined, then a supraspiracular one that seems to be iii, and 

 a subspiracular one that is v, or iv + v. These three are of almost 

 identical size and aspect ; vi seems to be represented by an Arctian
