is narrowed above but not at base. Thorax swells out again 

 behind groove towards width of caput, being strongly rounded, 

 and terminates in a truncated or even slightly hollowed end of 

 about half greatest width of thorax. 



Clypeus very low, top of caput flat and sloping very slightly 

 upward to eye 4, over which it is convex. Groove is very shallow, 

 hardly reaching as low as bottom of eye 4. Thorax rises very 

 slightly behind it, and then falls with an even but slightly convex 

 slope to rear end, where it rises concavely into a rim which can 

 be .traced along sides to caput. 



Colour dark mahogany, with black eye-frame broken in front 

 of eye 4 and terminating just below the level of eyes 2 and 4. 

 Scanty short grey hairs all over (Text-fig. 4, a.) 



Eyes. — 1st row straight by summits. 1.1 in contact, 1 . 2 

 close but not in contact. 2=^ 1 and slightly behind it. 4= or 

 very slightly > 2 . 3 < | 2, very slightly nearer. 2 than 4 and on 

 the upper tangent to 2 and 4. Eye square slightly broader than 

 long, with eyes 4 projecting prominently at hind corners and 

 4 . 4 very slightly > 2 . 2 and > distance between itself and rim 

 of cephalothorax. 



Falces. — Very nearly as long as caput. Length > 2 breadth. 

 Project horizontally forward. Sides subparallel, with inner edge 

 straight to about f and then rounded off to base of margins, 

 outer edge very slightly convex. On side view straight at lower 

 edge, upper edge strongly convex making falx very much thicker 

 at -t to g than elsewhere. Unguis ==| falx, sickle-shaped with 

 base much thicker than tip and curve with a tendency to being 

 straight in the middle with angle inside near base. Groove is 

 marked. Upper margin has typically 8 teeth, of which the first 

 three are close together at base of unguis, increasing rapidly in 

 size from 1 very small to 3 large, 4-6 are large teeth, 7, 8 rapidly 

 decreasing till 8 is very small. 4-8 evenly spaced. 1 and 2 and 

 8 are sometimes missing. Lower margin has 8 to 10 or more 

 very small teeth close together and reaching from base of unguis 

 to a little beyond angle, but always terminating before the upper 

 ones. They or at any rate the middle ones are alternately large 

 and small. There is a strongish scopula of long grey hairs on 

 upper margin, largest at angle, and of short dark scanty hairs on 

 lower margin. 



Colour dark mahogany as cephalothorax. The falces are 

 glabrous and somewhat rough. 



MaxillcE. — Length = coxa + troch. of 1st = falx nearly. Outer 

 edges parallel from base to apex of labium, then still remain 

 straight but incline slightly outwards. Outer corner is well 

 rounded and end square, a serrula following the edge from about 

 middle of outer side to end of straight portion. Inner corner very 

 slightly rounded and truncation straight and nearly parallel axis 

 runs back more than half way to labium. Hence slopes slightly 

 outwards and follows labium back to base, being hollowed out to 

 enclose it. Truncation has a strong scopula of black hairs which
