ANT-LIKE SPIDERS FROM MALAYA. 



291 



Epigyne. — A pair of white oval spots with a darkish mahogany 

 bridge between expanded at both ends. The whole on a ground 

 of the same colour. (Text-fig. 4, b.) 



Spinners. — 1st stout, subcorneal, light green-brown. 2nd very 

 thin, white, slightly longer than 1st. 3rd a little stouter and 

 darker than 2nd, much thinner than 1st, slightly longer than 1st. 



All have 2nd joint very much longer than 1st. 



Anus on a tubercle of two joints. 



Short Description. 



5 . Prosoma = opisthosoma. Caput = thorax. Groove very 

 slight, with thorax not rising appreciably behind. 



FaJces project horizontally forward, nearly as long as caput, 

 giving the appearance of 6 . Teeth, upper 8 strong at centre, 

 subevenly spaced ; lower 8 small, alternate sized, close. 



Legs 4.1.3.2, with 4 and 1, 3 and 2 nearly equal pairs. c t 

 and tr^ and tr 4 are very prominently white. Ti 5 has 6 spine pairs 

 or more often 6 and 7 spines, m ] 2 pairs., p ( none, p., none, ti., 

 3 pairs, occasionally a 4th, m 2 2 pairs stronger than on ti . 



Sternum rather broad. Gap C2.3 not > others. 



Pedicel short but visible from above. 



Opisthosoma squat, much thicker than usual in the genus. 



Note. — Description based on 13 $ from Biserat, K. Mahek, 

 c. Patani. It was found practically everywhere and is much the 

 commonest. 



2 . The c? is possibly M. biseratensis. 



Length varied from 3*5 (imm.) to 7'0 mm., the normal length 

 being 5 to 7. 



The accompanying ants were numbers 1 and 2. 

 Legs of a specimen, $ : —

2 c-f 2-0, p-ta 2-9 =4-9 



3 c-f 2-0, p-ta 3-2 = 5-2 



4 c + ti 1-4, f 2-7, p + ti 2-9, m + ta 2*3 =9'3 



Legs of another specimen, length 6'0, $ : — 



1 c-f 3-6, p + ti 3-2, m + ta 1-4 =8-2 



2 „ 2-2, p-ta 2-8 =5*0 



3 „ 2-2, „ 3-3 =5-5 



4 „ 3-6, p + ti 2-7, m+ta 2-6 =8*9 



Myrmarachne cornuta, sp. n. (Text-fig. 5.) 



2 . Prosoma. — (a) Length = opisthosoma. Greatest breadth 

 very slightly > v greatest height and each nearly | length. Caput 

 = thorax. Front wall straight, slightly stepped back to eyes 2. 

 Side walls slightly convex. Rear wall procurved where it slopes 

 back to groove where p.s. is narrowed above but not at base, 

 though white wedge makes it look as if strongly constricted. 

 Thorax swells out again behind groove to width of caput and 

 then narrows with straight or almost concave edges to base,
