THE REARINTr OF FA'NOMOS At'TI'MXARIA. 229 



crossed the spiracular line, finishing at a warty projection. The under- 

 surface was black between the legs, and light blue-grey between the 

 abdominal and anal claspers. The anal flap was pointed in shape, 

 with a shorter projection on each side, from each of which proceeded 

 two bristles. The anal segment below extended in two fleshy and 

 pointed terminals, each bearing a bristle. 



On June 15th, the larva had grown to be rather over fin. long; 

 was slender in form, and, to the naked eye, drab in colour. The warty 

 ridges on the abdominal segments— two, five, and eight — were now a 

 prominent feature, especially the first-named, which projected boldly 

 from the dorsal surface transversely across the larva. With the aid of 

 the microscope the drab colour of the creature was found to be 

 produced by an infinite blending of blotches and markings of black, 

 white, and brown, on a greenish-yellow ground. The head still 

 possessed the jaguar-like markings of dark blotches, but the 

 resemblance was not now so striking, as the ground colour was stone- 

 grey instead of chestnut. The series of lateral warts was still present 

 on each cheek, but were now principally white in effect, the black 

 centres having dwindled to a mere dot. They were still surrounded 

 by a fawn-coloured ring. The lateral projections, forward from the 

 jaws, were as evident as before, of a light warm drab colour, and each 

 one tipped with an elongation of bristle. The dorsal surface still 

 retained the two subdorsal scalloped stripes, though these were 

 suggested only in a faint degree, as the irregularity of the markings 

 had broken up their continuity in addition to the suft'used character 

 which the stripes had assumed. Reference was made in the last 

 examination of the larva to the reptilic character of the design on the 

 skin-surface, and comparison made between its appearance and that of 

 the serpent tribe. Now the skin seemed to be broken up and lozenged 

 into puzzle-shaped plates and wrinkles, which, as they were accentu- 

 ated by deep foldings and corrugated divisions, suggested rather the 

 hide of the crocodile in detail. This particularly was the condition of 

 the spiracular region. 



The ridgy transverse humps, on segments two, five, and eight, 

 were dark brown, reticulated with white, and possessed still the white 

 lateral spots, though these were now more suftused in character, and 

 were surmounted by a dark bristled wart. The transverse skinfolds 

 between the segments were heavily scored and fawn in colour. They 

 still retained, each one, the white lateral spots, though these were now 

 almost suftused to obliteration. The dorsal markings terminated in the 

 strongly accentuated fleshy folds above the anal segment, and these 

 were thickly studded with bristly dark warts. The anal segment was 

 also fawn in colour and showed several tubercles with light set*. 

 The anal flap was scalloped at the edge, showing four blunt points, 

 each carrying a dark tubercle set with a stout bristle, light in colour. 

 The two pointed projections from the extreme rear of the anal segment, 

 between the claspers, were very pronounced in form, and they, also, 

 carried each a dark tubercle with a light bristle. The claspers and 

 legs were fawn in colour, blotched and marked with darker. The legs 

 were received into the body by heavy foldings of the cuticle, which 

 was a dark brown between the creases. The spiracles were similar in 

 colour to the last record of their appearance, excepting that they were 

 not now quite so beautiful. The centre was golden with a dark
