marks ; • spiracles white on a dark mark extending forward to 

 the next incision ; hairs reddish-salmon ; head black with the 

 large lateral area reddish, and clypeus reddish with a black 

 centre." 



The newly hatched larva is pale, but very soon the raised 

 spots or tubercles become black, and some of the segments 

 present the usual alternate pale and dark colouring, while the 

 eleventh segment is, as in the other species, weak ; the pale seg- 

 ments are pale reddish, the raised spots on them being ringed 

 with white ; the dark segments brown, with reddish rings 

 round the raised spots. The hairs are few, either one, or five to 

 six, on each spot, and of unequal length, black. After the first 

 moult the body is darker, appearing blackish, but with the 

 tubercular spots ringed with paler ; the fifth segment is en- 

 larged and the twelfth decidedly humped ; the hairs longer and 

 more numerous. As it approaches the second moult the colour 

 has become fuscous-brown, and the white rings round the spots 

 take the form of a series of small orange-yellow spots and 

 blotches; those round the lower lateral tubercles almost form a 

 yellow lateral line. After the next change of skin it is again 

 black, the tubercles and more abundant black hairs leaving 

 nothing else visible except a reddish lateral line and some 

 pale markings in the hinder segments. It now begins to 

 sit in the peculiar attitude of the larva when full grown — 

 "head pressed flat, with the jaws forward; dorsal surface 

 rising thence rapidly to the hump on the fifth segment, then 

 falling with a hollow sweep to the eleventh, and rising 

 suddenly to the hump on the twelfth." After the third moult 

 the fifth segment is more conspicuously humped, the general 

 colour is black, but there are conspicuous square white mark- 

 ings on the eleventh and twelth segments, and similar indica- 

 tions on other segments ; also a row of dorsal red spots, which 

 tend to be red transverse lines, in the incisions of the 

 segments ; and a broad red lateral line. After the next 

 change of skin the larva " viewed dorsally, looks like a black 

 cross in a white setting ; the dorsnm is black and the fifth
