i.e., in the process of drying it forms into natural crystalline 

 shapes. Of course, this crystalline formation would occur so 

 rapidly on deposition of the ova that it would be difficult, if 

 not impossible, to detect. It is probable, however, that the 

 bathing of the ova continues until the ovum is excluded from 

 the oviduct. 



At the top of the egg-mass, where the incision would be 

 first made, a few ova remained smooth when dry. This 

 detracts nothing from the foregoing, as I conclude that these, 

 being earliest exposed to air, were insufficiently bathed by the 

 necessary sculpture-producing fluid. 



The results of this examination justify the conclusions 

 suggested by the experiments of Messrs. Woodhead and 

 Dawson, to which I refer in Part I. of this paper. 



Larva. (Plate XIII. , figs. 5, 6.) 



The first meal consists of the empty eggshell, and, though 

 frequently disturbed so that the larvae moved away or 

 dropped by a thread, they invariably returned and recom- 

 menced feeding on the eggshells. 



Newly hatched. — Eobust, slightly tapering towards pos- 

 terior ; head large and long, tubercles prominent, setae long 

 and widened at tip. The first two pairs of abdominal feet are 

 small, that of segment 3 being little more than large tuber- 

 cles provided with hooks. Neither pair of segments 3 and 4 

 seems to be used, so the larva in walking progresses in serni- 

 looper manner (fig. 5). Colour, reddish. Skin smooth. 



Head : Setae pointed, mandibles serrate. 



Prothorax : Scutellum bears on each side two separate 

 anterior and two posterior setae. Supraspiracular tubercle 

 bears two setae ; prespiracular two setae (?) ; tubercle above 

 legs two setae. Meso- and post -thorax, three smgle-seta 

 tubercles, one below the other ; one anterior and one posterior 

 lower each with one seta. 



Abdominal segments : All the tubercles bear a single seta. 

 Trapezoidals normal. Supraspiracular beneath the anterior 

 trapezoidal and above the round spiracle, immediately pos- 

 terior to which is one subspiracular tubercle, and below the 

 spiracle is the other. The abdominal feet bear two single- 

 pointed setae, which are subventral on segments 1 and 2. On 

 segments 7, 8, and 9 there seems to be only one subventral 

 seta each ; segment 10 has all pointed setae. Two subdorsal 

 posterior, curved downward, two posterior, curved upward, 

 and two on each of the claspers. 



On the 1st May some of the larvae had changed to second 

 and some to third skins. 



Second Skin. — Colour, pale-green, head pale - brown ;
