seen, and in Adocima it is very marked*. The pygidium in the males (?) has a short 
additional anal appendage. The stigmata are on the upper side, close to the fimbrie. 
Legs short. Coxe of middle legs near each other. The thighs below with a flat channel 
for the reception of the tibize, which have at the apex on the outer margin a small chan- 
nel for the reception of the tarsi; the inner side of the apex has small terminal spurs. 
The tarsi can scarcely be said to be dilated; the first three articles have a brush of hairs 
beneath; the last article, longer than all the rest put together, has simple claws.

. The species included in this genus may be divided into various subgenera, which 
arrange themselves naturally together according to the countries from which they come. 
The chief characters are the following :—1. In the New Holland species the margins of 
the thorax are ciliated or fringed with hairs, and the lobes of the ligula are very slightly 
developed. 2. In the Caffrarian and East Indian species the margins of the thorax are 
not fringed, and the lobes of the ligula are well developed. 3. In the species from West 
Africa and South America the margins of the thorax are not fringed, and the lobes of 
the ligula are very slightly developed. And these, again, may be subdivided into other 
sections. 
The following dichotomous Table may save time in the determination of the section to 
which the species belong :— | 
Abdomen with the first two segments considerably shorter than the rest . . 1

apply to all the forms of this section. It does apply to most of them, as can be easily seen 
by a dissection of the segments of Colastus, Carpophilus, &c. ; but the Brachypeplide form 
an exception ; and the occurrence of this deviation in that section would form a good sectional 
character were it not that in many species it can scarcely be seen without destroying the insect. 
The structure of the segments where fimbriee occur both above and below them can be 
easily explained by imagining a repetition of the arrangement in the simpler type, where they 
occur only on the dorsal surface, the fimbriæ and transverse continuation of them as rings N.B. Rounded to show 
both above and below forming the framework into which the remainder of the segment, tan d the supposed 
viz. a dorsal plate and a ventral plate, respectively fit.
