426 Dr. T. A. Chapman's Notes on 



ment; it contains on each segment some pale transparent spots 

 on each side (as well as liair bases); there is an interrupted red 

 line rather above middle of slope, consisting of a red spot towards 

 posterior margin of each segment, continued to front of segment, 

 forwards and upwards by a paler reddish colouring, fading out as 

 it passes forwards ; it is about half-way between spiracles and 

 dorsal band. Spiracles are black, not very conspicuous, being 

 small, probably because the larva is very full-fed in this instar; 

 along the flange is a reddish line, very weak in front, conspicuous 

 posteriorly, and joining at posterior margin of flange with dorsal 

 and slope lines. Head black. Seen laterally, the segments mesoth. 

 to 6th abdominal are raised as rounded eminences highest at front 

 margin of segment ; legs blackish, underside pale without coloration. 



June 4th. — Largest larva in 3rd instar; ate skin at 2nd 

 moult. Coloration same as that of 2nd instar, except that 

 black hair bases are numerous and give a tone to the larva, 

 and the lateral line is hardly visible on anterior segments. 



June 9th. — The rest are now in 2nd instar, about 2 mm. 

 long, yellowish white, broad red dorsal band, expanded a 

 little in each segment, and a minute red dot in middle of 

 slope of each segment. They mine into the leaves, but 

 always extrude frass, even when in first skin ; they are 

 well enclosed in the mine. In second skin the mine is more 

 open, and the covering cuticle is not often left. 



In the last instar there is a remarkable resemblance of the 

 front of the larva, when viewed in profile (laterally), to some 

 small mammal, especially perhaps a shrew mouse. When 

 the head is retracted, the prothoracic plate marks a depres- 

 sion, and the front of the prothorax extends as a flap, looking 

 much like a snout, whilst the first spiracle suggests an eye. 



PI. CIV, fig. 3, does not show this, but it shows how easily 

 this effect would be produced by retracting the head and 

 extending forward the anterior margin of the prothorax. 

 This resemblance is not on too small a scale to prevent it 

 from suggesting to some predaceous insect enemy, say an 

 inch or two off, a shrew or other doubtful presence at, say, 

 8 or 9 inches away. 



July 1st — 



A newly changed pupa is of Lycaenid form, but rather more 

 pointed than usual at the cremastral extremity, by which it appears 

 to hold, the larval skin being got rid of. The wings are green and 

 translucent, but the rest of the pupa is white with a faint creamy 

 tint, and has a rather broad brilliant rose-pink dorsal line, with
