East-Indian Chilopoda and Diplopoda. 61 
Head and collum deep fuscous or blackish olive. Antenne 
and legs, except proximally, bright green. 
Head rather weakly and not densely punctate, the sets 
moderately long. Concave above as usual. Antenne short, 
the last article strongly thickened and with numerous 
sensory cones in the usual manner. 
Collum of the typical general form. The transverse ridge 
much slighter than in the preceding species, with surface 
caudad of it scarcely depressed. Punctze rather sparse and 
weak, 
Second plate strongly margined laterally and anteriorly; 
a conspicuous wide furrow along the elevated border, the 
ridge caudad and mesad of this furrow low, not rising above 
the level of the middle region of the plate, from which 
separated, however, by a weak depression or furrow. 
Surface appearing smooth, the puncte obscure. In the 
other tergites the anterior part of the plate is sparsely 
scabrous, ‘and the free posterior portion nearly smooth, a 
little punctate and coriariously marked anteriorly, but at 
most very weakly coriariously marked posteriorly. 
Anal tergite with caudal margin not at all incised or 
emarginate at middle. Surface with numerous weak 
puncte and also obscurely marked with impressed lines, 
vaguely subcoriarious. 
Legs wit! a single spine above the claw. 
Hach piece of the vulva of the female as a whole subconical 
in outline, flattened antero-posteriorly as usual, the outer 
margin convex, tle mesal one nearly straight. Apical piece 
usually large ; its median length nearly equal to that of the 
basal piece, extending down outside the latter to its base. 
Length (female) 54 mm.; width 17°5 mm.

The only diagnosis of Pocock’s C. hirsutellum from 
Paragua (Palawan) available to me is so brief that I cannot 
be wholly certain of its relation to the present species. That 
author’s C. porosum, also described from the Phillippines, 
is widely different. In view of the fact that it lacks the 
characteristic enlargement of the last antennal article, 
the latter being simply cylindrical and bearing only four 
sensory cones instead of numerous ones, it should be 
separated generically, aud may be known as Castanotheroides 
porosus (Pocock).
