Erebia palcvrica and Ercbia stygne, 25 



on the thoracic segments. They have the second bead at the other 

 end of the segment sad just above the sub-dorsal stripe. Another 

 line of large tubercle-beads (one in the centre of each segment and 

 nearly in a vertical line with the spiracles) runs down the larva 

 between the spiracular and supra-spiracular stripes. These last 

 beads are doubled on the 2nd and 3rd thoracic segments. They 

 generally approach the supra-spiracular stripe, entering its lower 

 edge on the 6th abdominal segment and remaining in the stripe 

 afterwards. Above the lateral border are two small beads, the first 

 in the front of the segment, the other farther back and higher. All 

 beads have short transparent hairs. The feet and claspers have each 

 two or three beads bearing longer hairs than those on the body, with 

 the exception of those growing from the tubercles on the 8th 

 abdominal and anal segments. 



" There are three conical tubercles on each fork (last segment) point- 

 ing backwards and giving rise to single, rather long, transparent 

 hairs. One of these tubercles terminates the fork ; the two others 

 are lateral. The ground-colour of the body is a pale straw-grey. 

 The stripes are pinkish-brown. Dorsal line weak on the thoracic 

 segments, well-marked on abdominals. Sub-dorsal line narrower 

 but better marked on the thoracic segments. Supra-spiracular and 

 spiracular both well marked, the former thickening as it runs down 

 the body, and continued along the edge of the forks. The space 

 between the lateral edge and the spiracular line is very light. 

 Beneath the edge, and therefore within the limit of the ventral 

 surface, is a very narrow pinkish-brown line. The stripes are 

 broken by the segmental and sub-segmental incisions. The dark 

 colour does not penetrate the crevices. This is most marked in the 

 case of the sub-dorsal and supra-spiracular stripes. Ventral surface, 

 claspers and feet of the usual pale straw-colour. Forks : short, 

 thick, and lying close. Claspers on last segment large, with several 

 hair-bearing tubercles. The spiracles are round, dark-brown beads, 

 no larger than the tubercles above them except on the 1st thoracic 

 and 8th abdominal segments, but they are rather lighter in colour. 



" The larvae ate the grass I was able to give them, but it 

 was too tough and dry to nourish them properly, so they 

 soon died. No good grass was obtainable owing to the 

 drought. In course of time I was able to improve the 

 grass by watering, but it was then too late.
