166 THE entomologist's record. 



In the course of a day or two the larva becomes shorter, the head 

 is drawn down, the dorsal area much humped centrally, the anal 

 segment still, however, resting on the ground. The greenish hue 

 present in the active caterpillar entirely disappears. The colour is 

 very pale, whitish-grey, and almost unicolorous, except for the dark 

 medio-dorsal line, which retains its chief characteristics. The 

 segmental incisions are more distinct than in the active lar\a. The 

 transverse, sub-segmental arrangement of the warts and their hairs is 

 more evident, and the larva loses, more or less, its hold on the grass 

 culm, but still maintains its vertical position, by virtue of the anal 

 segment resting on the ground. In this quiescent state it remains 

 about seven days, when it turns to a short blunt pupa, without 

 attachment. The structure of the cremaster, which terminates in two 

 blunt blackish points, is such, that it may be taken for granted that 

 there is no possibility of this species suspending itself. 



III. — The newlt-fokmed pupa of Enodia hyperanthus. — On the 

 morning of June 12th, I was fortunate in finding a pupa of Knndia 

 Jn/piranflms, which had evidently only pupated, at the most, a few 

 hours. The larva had been in the quiescent stage a whole week. 

 The marvellous transparency of the external organs, led me to make 

 a note upon the newly- formed pupa. 



The ventral area is quite transparent — wings, antennae, legs and 

 maxillse. Through them, the usually hidden ventral parts of the 

 thoracic, and the 1st, 2nd and 3rd abdominal, segments are distinctly 

 visible, as gristly-looking continuations of the dorsal rings of the same 

 segments. At this stage these transparent areas are quite spotless, except 

 for the darker glazed eye, and a brownish discalmark towards the base of 

 the wing. Poulton's line is faintly traceable as a sort of ill-defined 

 depression just within the apex of the wing. The abdominal 

 segments ventrally are not transparent, but of the palest wainscot tint. 



The dorsal area is opaque, of the palest possible wainscot tint, 

 with a pinky hue about the thoracic segments. The meso-thoracic 

 ridge (which is ill developed as such) is marked with a sub-cutaneous, 

 fine, pinkish line (evidently part of the medio-dorsal stripe), and has 

 on either side a minute black tubercular dot. Otherwise the well- 

 developed, and comparatively large brown rims of the pro-thoracic 

 spiracles are the only darker markings visible on the thorax. The 

 waist (meta-thorax and 1st abdominal segment) tends to be slightly 

 transparent, thus approaching, but not becoming so in the same degree, 

 the transparency of the ventral area. The abdominal segments are of 

 the palest wainscot, with faint brownish incisions, the brown cremaster 

 bent backwards ventrally. A trace of the medio-dorsal line (evidently 

 a continuation of that on the meso-thorax) commences on the 6th 

 abdominal, and runs backwards to the anal segment. 



Lateralh/, the spiracles on the abdominal segments 2-8 are rather 

 distinct, appearing as black specks (to the naked eye), but being well- 

 defined structurally under a lens of moderate power. A few black 

 dots are also visible at the base of the ridge, along the inner margin 

 of the wing. 



IV. — Variation in the markings of the pupa of Enodia hyper- 

 anthus, WITH SOME NOTES ON THE COLOUR CHANGES PRECEDING EMERGENCE. 



— It is generally assumed that the pale wainscot-tinted pupa of 

 E. hyperantlms has certain characteristic dark longitudinal streaks
