4 Description of the Larva of Tryphena Curtisit.—I am by 
no means certain what is the natural food of this species ; 
but in confinement it feeds freely on Plantago lanceolata 
(narrow-leaved plantain) principally during the night, resting 
in a perfectly straight position on the leaf-stalk during the 
day, or even concealed beneath the surface of the ground. 
The head is rather narrower than the 2nd segment, and is 
porrected in crawling on the same plane as the body; it is 
highly glabrous, and emits a considerable number of soft 
flexible hairs directed forwards; the face is flattish, and there 
is no perceptible notch on the crown: the body is almost 
uniformly cylindrical; the three thoracic segments are however 
decidedly more slender than the rest, especially when elon- 
gated in the action of crawling; they are also transversely 
wrinkled, each being divided into four sections, in addition 
to the fold or quasi-section which intervenes between each 
two segments; the 12th segment is dorsally elevated, and 
the raised portion terminates posteriorly in a square and 
sharply-defined truncature; there is a lateral skin-fold 
below the spiracle, but not very conspicuous; the anal 
claspers are stretched out behind when at rest, and extend 
decidedly beyond the anal flap: when annoyed the larva 
falls from its food-plant in a compact ring, and remains in 
that position a considerable time perfectly motionless: in 
this position the slender hairs scattered over the body 
become more perceptible, but are never very conspicuous ; 
the skin is velvety. The colour of the head is a transparent 
palish umber-brown, but variegated and reticulated with rich 
sepia-brown ; these darker reticulated markings form two 
quasi-crescents, the convexities of which are placed back to 
back on the middle of the face, and two other somewhat 
similar but smaller markings on the sides of the cheeks 
scarcely perceptible from above; the ocelli are of the same 
dark colour as these facial markings: the colour of the body
