Tre ABLABERINI. 
Body elongate, sub-cylindrical or with the elytra slightly ampliated 
in the posterior part, but occasionally short and convex, although 
less than in Trochalus (Oocamenta); clypeus gradually narrowed 
laterally and either straight or sinuate before the apex, but occa- 
sionally plainly constricted (Idecamenta), eyes divided in front by 
a short genal canthus, and without any posterior keel ; antennze 9- or 
10-jointed; prothorax not very convex and with a fringe of long 
sete ; elytra elongated and covering the propygidium which is wide 
and slightly convex; anterior cox sub-vertical and conical at apex, 
very little slanting in the base, intermediate and posterior ones not 
widely separated, the posterior slanting and only one-third the width 
of the metasternum the episterna of which are slightly narrower 
and of course longer than in the Sericini; femora not broadly 
ampliated, tibize not compressed, hind ones with only a slanting 
spinose ridge; hind spurs of the female visibly yet not strongly 
ampliated. 
The variable number of antennal club joints has led to a great 
generic division where specific distinctions, would, in my opinion, 
have achieved the same result. 
This great variation in the number of joints of the antennal club 
is a curious feature of the insects included in this Tribe ; it varies in 
the male from 7 to 4, and from 6 to 3 in the female; the claws are 
slender and not deeply cleft underneath, but the basal part is often 
dilated and membranaceous. 
On the whole the Tribe is very homogeneous, but certain genera, 
such as Tulbaghia and Idecamenta, are closely allied to the Pachy- 
podous Melolonthine, and have probably the same habits. The 
females of Ablabera, Camenta, &c., are, however, met with as 
commonly as the males. 
The species of Ablaberini seem to be more restricted to the South 
African Fauna than the Sericini ; a few of them have been met with 
as far as Masailand, but I believe that none are found in Senegambia. 
The range of the species in South Africa is very limited, differing 
in that respect from the Serzcini, but the habits of the two seem 
to be the same.
