of the anal pleurae. Perhaps it comes nearest to the 9 of the 
Ceylonese and Indian species H. spinosum of Newport, but this 
last species is much more robust, the sternal sulci are less 
conspicuous, the tarsi of the 20™ pairs of legs are spurred and 
the anal claws are distinctly spined at the base. 
21. Cryptops feae, sp. n. 
Colour; of a uniform ochraceous tint throughout. 
Head plate somewhat pentagonal in shape, overlapping the 
anterior border of the first tergite, marked in its posterior half 
by two fine anteriorly converging sulci, sparsely marked with 
setigerous punctures. 
Antennae of normal length, composed of 17 segments and 
thickly clothed with shorter and longer bristles. 
Maxillary sternite with anterior border almost straight, very 
lightly sinuate, bearing four short bristles on each side; claw 
of normal length and curvature, somewhat slender. 
Tergites with the ordinary complete sulci and the lateral, ab- 
breviated, curved, oblique sulci; the second tergite without the 
lateral sulci, but with the median sulci complete; the first ter- 
gite also conspicuously sulcate, there being a conspicuous anterior, 
angular, transverse sulcus, to the angle of which the two 
longitudinal sulci converge, eventually meeting it in a depres- 
sion; all the tergites, except the last, with unraised lateral 
margins. 
Sternites with the ordinary cross-shaped arrangement of sulci. 
Anal somite; tergite with straight, sub-parallel, raised lateral 
borders and angularly produced posterior border; plewrae smooth 
behind, conspicuously marked with many — 15-20 pores in 
front; sternite wide, nearly parallel sided with rounded angles 
and straight posterior border; /egs normal in shape, femur and 
patella thickly armed beneath with stout spiniform hairs, tibia 
furnished beneath with a series of five or six short dentiform 
spines, and the first tarsal segment with a series of three or 
four similar spines, metatarsus not spined ; the femur is furnished
