NOTES ON LIFE-HISTORIES, LARVAE, ETC. 213 



The PROTHOR.AX is very different in its armature from the meso- 

 and meta-thorax. The anterior and posterior trapezoidals are placed 

 directly behind each other in two pairs, one pair on either side of the 

 median line. A well-developed lateral tubercle on each side of these 

 is evidently the supra-spiracular, whilst there are well-developed pre- 

 and sub-spiracular tubercles. The spiracle itself is placed well back 

 toAvards the segmental incision, and is larger than the abdominal 

 spiracles. The meso-thorax and meta-thorax are very similar in 

 their structure and armature. They are narrow, and the tubercles 

 are crowded into a single transverse row, five on each side of the middle 

 of the dorsum. These represent in order, judging from the analogies 

 of the tubercles of the pro-thorax, the anterior trapezoidal, the 

 posterior trapezoidal, the supra-spiracular, the pre-spiracular and the 

 sub-spiracular tubercles. Of these, the pair nearest the median line 

 of the dorsum {i.e., the anterior trapezoidals) are very small, the 

 posterior trapezoidals well-developed. Below the sub-spiracular 

 tubercles is a slightly tumid longitudinal ridge, below which, on each 

 of the thoracic segments, is a marginal tubercle just above the legs, 

 and another in front and another behind the base of each leg. The 

 legs are greyish, with a single terminal claw, and a few grey hairs 

 at each joint ; a black ring surrounds the leg where it joins the body. 



From the 1st to the 8th abdominal segment the tubercles are 

 arranged in typical fashion, viz., the anterior trapezoidals on the 2nd 

 (?) subsegment, placed somewhat closer together than the posterior 

 trapezoidals on the 4th (?) subsegment. These make up the dorsal 

 series, whilst the lateral series consists of a supra-spiracular tubercle, 

 a post-spiracular tubercle and a sub-spiracular tubercle. It will be 

 observed that on the abdominal segments there is a post-spiracular 

 and no pre-spiracular tubercle, whilst on the thoracic segments there 

 is a pre-spiracular and no post-spiracular tubercle. On the 9th 

 abdominal segment the tubercles are crowded, and the trapezoidals 

 lose the definite positions of the preceding segments, whilst on the 

 anal segment the hairs of the tubercles form a sort of marginal 

 fringe, the tubercles being placed on the lateral edges of the flap. On 

 all the segments the tubercles are simple raised warts, and bear a 

 single black hair. The colour of the 8th, 9th and 10th abdominal 

 segments is yellowish rather than green. 



The larvae loop very distinctly. They possess, when newly-hatched, 

 anal prolegs, and a pair of prolegs each on the 5th and 6th 

 abdominal segments. Those on the 3rd and 4th abdominal 

 segments are traceable (with a one-sixth lens), but are totally useless for 

 walking purposes. At rest, the larva is extended, but when startled, 

 draws itself up. Geometer-fashion, into a hook before dropping by a 

 silken thread. (LarviB hatched 29th June, 1896. Described 30th June,

Egg of Enodia hypeeanthus. — Unattached. Surface very finely 

 ribbed, shiny, pale yellow in colour ; a deep depression at the 

 broad end, which is somewhat flattened ; the remainder of the egg 

 forms about f of a sphere. Edge of summit pitted with concentric 

 rings of polygonal cells, which are continued down the sides, the micro- 

 pylar cells forming a rosette of very minute cells, but with scarcely any 

 trace of a special micropylar depression. A bright yellow patch near 

 apex of egg, with two or three brown spots, the remainder of egg pearly
