than the first, more than twice as long as the second, and a 

 trifle longer than the fourth. There are three odoriferous 

 orifices. 



The nymphs like the adults, are conspicuous bj the clear, 

 whitish, last antennal segment.

This genus is evidently of considerable geologic antiquity, as 

 it is not only very widely distributed, but has a number of un- 

 doubtedly endemic species on various oceanic islands. In these 

 islands, however, outside the 14 described endemic species, 

 there are three introduced species, viz., coenosulus, reported in 

 1859, delectus in 1878 and vvnitor now recorded. 



8 vvnitor Bergroth. 



This is a well known pest in Australia on 'vines' of all sorts, 

 cherries and many other kinds of fruits and vegetables (^°). 

 In Hawaii, it is very common on Ihi (Portulaca oleracea) and 

 has been reported from melon-vines. 



I have not yet discovered the eggs, nor has any of the Aus- 

 tralian Entomologists. 



Fifth instar: Yellowish or greenish testaceous, vertex with 

 2 dark brown median straight stripes and 2 lateral (2 on each 

 side) more irregular stripes, turning outwards apicalwards, 

 also some obscurer spots or marks. Clypeus laterally bordered 

 straightly with dark brown. Antennae pale fuscous, fourth 

 segment a little darker. Nota and tegminal pads irrorated 

 with dark and pale fuscous, a central pale line down the middle. 

 Abdomen irrorated with reddish brown. Femora (except 

 apically and basally) dark fuscous, rest of the legs pale. La- 

 bium reaching just beyond the hind coxae. Pronotum medially 

 a little laminate. Fore coxae approximate, the others a little 

 remote, though not much. Arolia rounded, free, shorter than 

 the claws. Odoriferous orifice very short and wide, on the 

 5th tergite. 



9 delectus F. B. White. 



This is very close to the preceding but much larger. The 

 nymphs are very similar, but proportionally larger in each
