22 Dr. T. A. Chapman on 



The following description was taken some time after 

 returning home ; it may have some value as a description 

 of first stage of stygne, but palarica having all died, it is 

 useless for comparison with that species, still less, of course, 

 will the later stages have the value hoped for when I 

 thought I might rear both species. 



Erebia stygne (small form), Aug. 24th. Larva full-grown in first 

 stage, length 4*8 mm., head looks very small, about - 5 mm. wide, 

 forward segments being quite - 9. It tapers very steadily from 2nd 

 or 3rd abdominal to tail, 9th abdominal segment being about 05 mm. 

 across, 10th smaller. 



Ground-colour whitish terra-cotta, a narrow dorsal red-brown band 

 (or line) broadest at 5th or 6th abdominal. Then a broad pale band, 

 which includes both I. and II., which are widely apart, one at front, 

 other at hind-margin of segment, and II. quite twice as far from 

 middle line as I. Next, a narrow red line, then a pale one, nearly 

 white, i. e., decidedly lighter than general ground-colour. Then a 

 broader dark band, paler than the others owing to a good deal of 

 marbling of pale ground-colour in it, in this is III. Then a very 

 narrow whitish band and a very narrow brown (or reddish-brown) 

 line in which is spiracle. Then a broad yellowish-white band in 

 which are IV. and V. The anterior much the lower and the line of 

 spiracle just between them. Then a narrow reddish band, a slightly 

 broader pale one, and a narrow weakly-coloured dark one. Below 

 this is the proleg with two hairs at margin, and on 1st and 2nd 

 abdominal one hair in place of proleg, and another more ventral 

 (this may be more in situation of proleg), a minute one still more 

 ventral. No hair or tubercle is found on the three lines below the 

 band carrying IV. and V. Legs and prolegs pale fleshy, four hairs 

 and three dots like hairless tubercles on claspers. Head round, with 

 fine wrinkling, making it rough. The anterior ocellus very large 

 and prominent ; the second smaller, but very similar and very close 

 to it, the others flat and inconspicuous. The two first have pigment 

 in the epicranium, as well as the mass beneath. The head also 

 carries a number of hairs of the same colourless texture with rough 

 surface, curved and clubbed, as those of the ordinary tubercles. 

 The anal plate carries four hairs on conical tubercles along its 

 posterior margin, and one in either side higher up. On the pro- 

 thorax is a small plate on either side with four hairs, two in front 

 and two further back. Further down in line with plate, and well 

 above, and in front of spiracle, is a double tubercle of which the 

 front hair is short and curved like the others, but the second though 

 transparent and rough (not spieulated) like the others is straight,
