ANT-LIKE SPIDERS FROM MALAYA. 



321 



terminating in a short point in front of them. The legs appear 

 to spring from a separate chitinous plate lying between dorsal 

 shield and sternum, and produced into a long socket to take c r 



Pedicel. — Very short; it is just possible to see its point of 

 entrance below dorsal concavity at top, but it cannot be seen at 

 all from below. 



Opisthosoma. — Abdomen = 1^ cephalothorax, subcylindrical, 

 width = height — < 4 length. Rounded in front and behind, 

 being slightly wider behind, slight constriction half way. On 

 side view constriction at ^. Ground-colour greenish brown above 

 formed by a light ground dark-lined, two small white blotches at 

 constriction in a transverse line, followed by a large central white 

 blotch. From the small blotches white lines slope downwards 

 and backwards across the sides, getting wider as they proceed and 

 connecting with white ground-colour which prevails below behind 

 epigastric fold to spinners. Spiracular plates chitinous, yellow- 

 brown, and so wide apart as to be hardly visible from below and 

 noticeable from the side. Between them a strip of same colour, 

 but I think not chitinous. Epigastric fold is strongly procurved, 

 but not well marked. 



Epigyne. — -A small white semicircular pit edged with dark red 

 and with a pair of dark markings forming arcs of a semicircle 

 outside. Not very marked, but clearer than in Myrmarachne. 



Spinners. — As seen from below, spring from a very distinct 

 half-socket, the edges of which, however, are not continued round. 

 All spring from separate sockets inside the above and are 2- 

 jointed, the basal joint being very long, the second very minute. 

 1st. "Very slightly tapering, about twice as long as broad, brown- 

 yellow. 2nd. Equal length, lightest, slenderest. 3rd. Dark as 

 1st at base, light as 2nd at apex, intermediate in stoutness but 

 nearest 2nd, longest. 



Note. — The description is from a single $ found at Bukit 

 Besar, 2500 ffc. altitude, in cavity under the bark of a rotten 

 sapling. 



The following are measurements : — 



Total length 7*0 mm. 



Prosoma 2*7 long x 1*6 wide x 1:4 high. 



Opisthosoma... 4*6 ,, x 2*0 '„ x 2*0 „ 

 Legs. 



1 c + tr 1-4, f2-6, p 2-8, ti 2*0, m + ta 1-0 =9*8 



2 c + tr + f-2-4, p + ti2-0, „ 1-0 =5-4 



3 „ 2-5, „ 2-0, „ 2-0 =6-5 



4 c + tr 1-5, f 2-3, „ 3*0, „ 3-0 =9-8 



The legs were damaged and impossible to measure with 

 accuracy, so that either 1 or 4 may be the longest. 

 Ants accompanying, none.
