300 MR. H. D. BADCOCK ON 



Opisthosoma. Fusiform, not constricted. White belt at about 

 \ in 2 ■> missing in <$ . 



General colour of prosoma lightish mahogany with black eye- 

 frame, of opisthosoma dark greeny brown. 



Note. — The description is based on 12 $ and 8 d , all from 

 Bukit Besar and Talum. Nos. 93 $ and 94, 95 J were all in 

 same tube, and this fact as well as the general resemblance is 

 evidence of identity of species. 



The following measurements were taken : — 



$ 5-0 mm., p.s. 2-3x 1-2X1-2, o.s. 2*4 x 1'4 x 1'2. 

 Legs. 1. c + tr + f 1*7, p + ti 1*5, m + ta 1*1 =4*3 



2 „ 1-0, p + ti + m + ta 2*5 =3'5 



3 ,, 1*4, p + ti 1*0, m + ta missing 



4 c + trO-9, f 1-8, „ 1-9, „ 1-1 = 5-7 



S 5-2 mm., p.s. 2*4 x 1-4x2-0, o.s. 2-4. 



Legs. 1 c + tr + f 2 2, p + ti 2-4, m + ta 1-8

3 „ 2-1, „ 1-8, „ 1-7 



4...... c+tr 1-1, f 2-0, „ 2-3, „ 2-2 



The lengths of the specimens varied from 5*2 to 3*7 mm., the 

 J being on the average slightly longer than $ • 

 Ants accompanying, nos. 4, 14, 15, 17. 



5 . Myrmarachne cuneata, sp. n. (Text-fig. 7.) 



Prosoma. — (a) Length = p 4 + tr 4 + m 4 + ta 4 nearly, slightly 

 > opisthosoma. Caput = thorax. Front wall slightly projecting 

 in centre and stepped back to eyes 2. Side walls straight, very 

 slightly approaching backwards. Back wall strongly projecting 

 at centre into bridge. Bridge narrowed at top, only very slightly 

 at base, though it is liable to appear so owing to white wedge. 

 Thorax edges curve very slightly outwards to |, then inward to 

 rear, which is cut off convexly straight. 



(b) Front wall vertical, top of caput straight and level, groove- 

 shallow and broad, bottom not below eye 4. Thorax rises behind 

 to above half way up eye 4 at ^ and then slopes convexly back- 

 wards to rim, the final concavity before rim being negligible. 

 Rim rather marked and traceable round to caput. 



Colour medium mahogany, lightest at sides and much darkest 

 at top of caput. Eye-frame black, rather broader than usual and 

 very distinctly broken between eyes 3 and 4. A very strong 

 white wedge on either side of bridge, smooth and not due to 

 hairs. 



Eyes. — 1st row straight by summits, 1 . 1 and 1 . 2 subcontact, 

 2 slightly behind 1. 2=| 1. Eye square slightly broader than 

 long and sides'slightly approaching backwards. 2 . 3 very slightly 

 < 3 . 4, 4 = or very slightly > 2. 4 projects but not markedly 

 so, and 4-rim very much < 4.4. 



Falces. — Project nearly horizontally forward by lower edge r
