76 THE entomologist's record, 



tion into dark and light segments also exists in the hairs on the 

 dorsum; on 3.4.6, 10.11.12 and 13 being white or yellow; 

 whilst they are dark on 5.7.8.9 ; the forward tufts as already 

 noted, being darker than those brushed backwards. Two 

 larvae in this skin are larger than the others and their hairs are 

 brown and yellow (of the others blackish and dirty white). 

 These attained their last skin in one more moult, the majority 

 took another moult (5 moults), the 6th skin being the last (I 

 have here a note that aceris does not eat its cast skin, whilst 

 leporina does do so). 



In the 5th skin, the larva is substantially similar to the 4th, 

 but takes yellow and brown as the colour of the hair bundles, 

 just as the more forward ones in 4th skin did ; still their 

 colours are a little brighter, viz., light yellow instead of deep 

 yellow, and the brown has a pink tinge. Their heads are 

 also larger. The longest hairs in 5th skin are 7 mm. ; of the 

 forward larvae in the 4th, 6 mm. The tufts are 2 mm. long 

 in the forward larvae, rather more in the normal 5th. In all, the 

 dorsal diamonds are now much as in last skin. When the 

 " forwards" moulted into 5th (their last) skin they were much 

 smaller than their brethren, now well grown in 5th (their 

 penultimate) skin, but their heads were much larger, viz., that 

 of the adult larva. There seems no need to describe the full- 

 grown larva, but a few points may be noted ; the ground 

 colour of the larva is chocolate or black, but each hair has a 

 minute creamy white circle round its base, and these by their 

 greater or less development, tend to form two lateral lines and 

 rings round the tubercles. The tubercles are still very evident, 

 the three dorsal ones black, the others partially yellow. They 

 give rise to yellow hairs, but the great dorsal flame-like 

 brushes arise from the general surface, over considerable 

 areas in front and behind the posterior trapezoidal tubercle. 



The 6, 10 and 11 segments are still distinctly paler than 

 other segments in some larvae. The 2nd segment is hardly- 

 visible dorsally in ordinary attitudes of the larva, but it is not 

 so nearly obsolete as it is in Moma orion. It possesses a black 

 dorsal plate, fringed with yellow hairs, but quite obscured by 

 the greater tubercles and longer hairs of 3 which overhang it. 

 The hairs of 3 and 4 are mainly from the tubercles, trapezoidal 

 and supra-spiracular, which are very large and porrected. The 

 lateral (supra-spiracular ?) tubercles of 2 are large.
