ANT-LIKE SPIDERS FROM MALAYA.

thorax) of prosoma. There are also less distinct dots or streaks 

 radiating from centre and marking other thoracic divisions. 

 Dark portion is bordered by a thin white marking at hind 

 corners, and there is a very thin darkening at outer edge. 

 Cephalothorax is practically free from hairs except the bristle 

 fringes and a very slight thin pubescence at edges. 



(b) Olypeus slopes very gradually backwards and upwards with 

 convex section, and on this view is equal in length to eye-cliff, 

 its rise being very slight. Portion of face containing eyes 2 now 

 rises vertically or rather slightly overhanging, and from here to 

 centre of cephalothorax (which is well behind eyes 4) top is flat 

 with slight rise ; thence 45° slope to rear. White marking is 

 prominent at rear end and can be traced round to front as a fine 

 white line. Eyes 2 and 4 are also prominent on side view. 



(c) Olypeus slightly procurved and about = eye 1 ; top convex, 

 sides straight. 



Cephalothorax has somewhat the appearance of a death's head. 

 Eyes. — 1st row distinctly procurved. 



1.1 nearly —2 x 1 . 2, on slight tubercles of bluish tinge, 

 o. u. f. 



2 = 2x1, largest of the 4, on blue tubercle connected by valley 

 with tubercle of 4, the whole markedly blue, o. u. f. 



3 = 5 X 1, smallest of all, u. 



4 very slightly < 2, blue most marked and tubercle most pro- 

 minent, o. b. u. 



2 . 3 very slightly < 1 . 1 ; 3.3 = 4.4 approximately. 



Total length of 2nd row greater than 1st. Trapezium 1.3.3.1 

 is narrower behind than before and approximately as wide as 

 long. 



Falces nearly horizontal, projecting forward and very pro- 

 minent from above, broad at base and rounded, rapidly reducing 

 to apex and curving slightly apart on inner side so that there is 

 a distinct space between. Short tooth-like spines from about 

 ^ to apex, one on top near commencement being distinctly 

 stronger than the rest. Lower side free from hairs. Groove 

 indistinct and toothless. Outer margin has a thin scopula of 

 moderate hairs. 



Maxillce. — Long, nearly = falces, broadest at base, slightly con- 

 cave without and within round labium and tapering to a blunt 

 point, greatest slope being on outer edge. Short spines all over 

 lower side. Serrula on outer edge after concavity. Scopula 

 strongest at angle but also slight on inner side. 



Labium shaped like a Florence flask, length = maxilla == 

 3 breadth : blunt-pointed. 



Palpi. — One missing, other broken after patella. Light- 

 coloured, stout, cylindrical. 



Legs. — Mostly detached and damaged. 



1st. One missing, other broken after femur. Light especially 

 on top of f, which is marked with somewhat indistinct 

 longitudinal series of white spots.
