there is no depressed groove ; the terminal plate is large, rounded, 

 and almost entirely of the peculiar tortoise-shell appearance. 



The legs terminate in a sU'ongly formed hook ou one side of 

 the truncated top and a blunt stroug spine ou the other. Along 

 the internal side of the tarsal joint, below the hook, there are five 

 strong spines. The legs are hairy. 



Cojiulatory feet of the male (PL XXXII. figs. 79, 91). Posterior 

 foot: The movable dactylus is long and slender, and composed 

 of two segments of w'nich the proximal is the longest. There is 

 a ])ad beneath the proximal end of the terminal joint and beneath 

 the distal end of the proximal joint. The immovable dactylus is 

 broad and thin, not so long as the movable, and narrower at the 

 proximal end. Anterior foot : Both movable aid immovable feet 

 are single-jointed. The immo\'able is thin and broad ; the movable 

 is stout and curved. There is a soft, hairy pad between them. 



The tndva of the female consists of two parts on each side, one 

 heart-shaped (see PI. XXXI. fig. 57), uith a slit from the upper 

 end to near the midJle ; the other a short", si out cap. The eopu- 

 latory apparatus seems to show a strong resemblance to that of

The fact of the copalatory feet and vulva corresponding to those 

 drawn by Silvestri, together with the general resemblance to his 

 description o£ the species from Sumatra, suffices to identify the 

 species ; but as his account of the animal shows some points of 

 difference from the Malay spjcimen, I think the latter must be 

 put down as a new variety. 



Length 30 mm. by 16 mm. 



Colour castaneous, with slight tinge of green in some lights. 

 Antennae and legs lighter. 



Head broad ; upper lip very slightly indented ; antennae very 

 short and thick, with dotted pad at end, punctuated and hairy, 

 especially on lower parts. Porehead with sinuous indentation 

 where the edge o£ the 1st tergite fits in. Eyes in large circular spot, 



1st tergite smooth, not very long ; the raised part slopes down 

 to meet the depressed part at a steep augle. In the middle of the 

 back of the tergite, where this slope meets the marginal rim at 

 the sides, there is a flat space between the slope and the marginal 

 rim. The raised part has the shape of a very blunt lancet at the 

 sides. The lower depressed part is bounded by the marginal rim. 



3rd tergite. The 3rd tergite is very short and ends in a sharp 

 lancet-point. On the 4th the edge of the lateral extremity is cut 

 away by the lateral groove. The ventral groove is continued up 

 to the penultimate tergite. The surface of the grooves is rougii 

 and covered with small tubercles, but is without hairs. The last 

 tergite is smooth and polished like the others.
