Infe History of Lonchaea chorea. 315 
“ Die Puppe ist ein lingliches, quergestricheltes, hellroth- 
braunes Tonnchen. Der Thorax ist gerieselt. Der After- 
abschnitt porkat, mit vorstehender, schwarzbraunen Stig- 
mentrigern.—Lange 1} Linien.—Nymphenzeit vierzehn 
Tage.” 
Bouché gives but one figure, an admirable representation 
of the branching tracheal system of the larva, to which he 
refers in his text. As regards the breeding habitat, Bouché 
says he found the larva under the bark of trees, whilst 
Scholtz * discovered it amongst cow-dung. Mr. Austen 
informs me that he has bred the imago from larvae feeding 
on diseased bulbs of Crinwm and Brunsvigea cooperi, to 
which it would seem they are rather partial, and also from 
others in a rotten cabbage. Farsky + discovered the larvae 
in a erop of beetroot suffering from so-called ‘ Kernfaule ” 
or core-rot. 
THe Hae. 
The egg of L. chorea is very similar in size and appearance 
to that of many of the Anthomyudae, bearing on its outer 
delicate case a pretty ornamental sculpturing composed of 
minute hexagonal areas. By reason of their pure white 
colour they were easily recognisable in the breeding-cage: 
amongst the cow-dung, where they were deposited by the 
imagines. arsky gives their accurate measurement, stat- 
ing their size to be 0°8670 mm. long and 0°2500 mm. broad, 
After a period of about eight to ten days under ordinary 
conditions, the larva bursts the chorion longitudinally and 
emerges. In the laboratory . probably on account of the 
high temperature, only about half that time elapsed be- 
tween the act of oviposition and the appearance of the 
larvae. 
THe Larva. 
A certain number of the larvae were placed in a cool- 
house where the temperature did not rise above 50° F., 
and usually, indeed, the temperature remained a few degr ees 
below this—during ‘the night often falling well below 40° F, 
It was observed that the larvae under these conditions 
continued to feed, and pupation did not begin until as many 
as sixty to seventy-two days had passed. It would thus
