60 Mr. J. C. W. Kershaw and Mr. G. W. Kirkaldy on 



never hatched), were laid by a female after copulation. 

 This failure was certainly not due to mites or mould, as 

 the eggs remained firm and of fresh colour for several 

 weeks. It is probable that the females copulate after 

 each batch of eggs is laid. 



The eggs are laid touching one another, and are pale 

 hyaline-green, almost globular. A darkish-red marking 

 like a small nail (thus T ), and below this a curved red 

 marking (thus w ), the two resembling an anchor. There 

 is no peculiar cap to the egg, the hinge being merely 

 indicated by a ring of minute protuberances like a string 

 of pearls (PL IV, tigs. 1 and la). 



On the morning of August 28th, 1907, eleven ova were 

 laid, and on the morning of the 30th a black mark showed on 

 the centre of the curved red marking, the latter becoming 

 slightly altered. The next morning the general colouring 

 was yellowish, or pale pinkish-yellow, the red markings as 

 before. The nymphs hatched the same afternoon, less 

 than four days, remaining for several hours in a cluster on 

 one side of the empty shells, eating nothing till after the 

 first moult. 



This first instar is shining black, with yellowish-white 

 markings (PI. IV, fig. 2). 



The first moult took place on the afternoon of September 

 3rd, the metallic colouring then first appearing (fig. 3).* 

 The nymphs then separated to feed, re-forming in a 

 semicircular cluster at night. These young nymphs stand 

 up very high on their legs. 



The second moult took place on the 12th (fig. 4), and the 

 third on the 21st September, and soon after the few 

 remaining ones died. Fig. 5 represents the penultimate (?) 

 nymphal instar of a closely allied species, while fig. 6 

 shows the final nymph of G. stollii, the adult being shown 

 at figs. 7 and S.f 



The adults have a strong, disagreeable smell. They 

 fly well, but rather heavily, and are common in wooded 

 places and jungle during the wet season, though they are 

 to be found throughout the year. During the dry season 

 on very cold days they hide away under leaves, etc., often 

 creeping between leaves which a spider has fastened 

 together. 



* They are pale red for a few minutes after the moult. 

 t The pronotum is a little foreshortened in fig. 7, the lateral 

 margins of the pronotum beiug straighter.
