VIII. The larva ef Orgyia splendida (dubia). By

PuLaTE XI. 
I MET with this insect at Cuenca and Tragacete in 1901, 
and in 1903 found the larvae abundantly at Moncayo, still 
further to the north. My observations on the species 
were published in the Ent. Record, XIV (1902), p. 41, and 
XVI (1904), 195. 
Two excellent drawings of the larva, however, by 
My. E. C. Knight, have remained in my drawers from that 
date unpublished. This seems very unfortunate, and they 
are better to be printed now than not at all. Their special 
interest lies in the larva being decidedly ditferent in 
colouring from Freyer’s figure of dubia (Taf. 297), from 
Rambut’s figure of splendida (Fauna d’ Andalusia, Pl. XV, 
fig. 6d) and from Spuler’s figure (Nacht., Pl. II, fig. 13); 
the latter, from some source unknown to me, being most 
like it. 
Moncayo appears to be the most northern habitat of 
the species, the larvae are more brilliantly coloured, and 
the imagines have a larger area of orange yellow than the 
more southern or eastern examples. 
The brilliancy of the larva depends on the deep black 
especially of the tufts, contrasted with the white and red 
brown rather than black being the ground-colour of other 
figured larvae of the species. There are other colour- 
differences, which the figures absolve me from specifying. 
The species is certainly remarkable for having definite 
geographical races differing not only in the imago, but also 
in the larval state.
