Fam. Thomisid^. 

 Gen. Selenops Diifour. 



Selenops diteesus, sp. n. (Plate XXXI. fig. 1.) 



Adult female (No. 100), length 10 lines. 



General form and structure normal. 



Cejjhalothorax considerably broader (at its hinder extremity) 

 than long. Indentation at the junction of caput and thorax large 

 and deep. Colour dark yellowish brown, marked with somewhat 

 irregular pale markings and darker converging lines, and clothed 

 with short grey and other hairs, and with a rather dense marginal 

 row of short, curved, prominent spiniform bristles. 



Eyes in normal position. The four centrals of the anterior row 

 form a slightly curved line, the convexity of the curve directed 

 forwards ; the two central eyes are rather the smallest of the four, 

 and are further from each other than each is from the lateral eye 

 on its side. 



Legs long, strong, furnished with spines and numerous hairs of 

 varying length ; a scopula beneath the tarsi, and below the two 

 terminal claws a compact claw-tuft. The colour of the legs is 

 black, marked and, rather irregularly, annulated with reddish yellow- 

 brown ; the annuli are clothed with coarsish grey hairs. The legs 

 do not differ much in length, the second pair are the longest, and 

 the first, apparently, slightly shortest. 



Falces moderately strong, roundly prominent in front, straight, 

 and of deep blackish red -brown colour. 



Maxillw rather short, oblong, rounded at the extremity, inclined 

 towards the labium ; colour dark yellow, pale yellowish at the ends, 

 where they are furnished with fine white hairs. 



Labium slightly longer than broad, oblong, rounded at the apex, 

 which is yellowish, the rest deep brown. 



Sternum rather longer than broad, short-oval, slightly truncated 

 before, and notched at its hinder extremity. Colour pale dull 

 yellowish brown. 



Abdomen flattened, rather longer than broad, nearly quadrate, 

 truncate before, the posterior corners well rounded. Upperside 

 of a dull brownish hue, pietty thickly clothed with short greyish 

 hairs, some of those on the sides disposed in minute groups or tufts 

 giving it a spotty appearance; along the middle is a rather diffuse 

 but symmetrical black pattern, formed by a central longitudinal 

 stripe, emitting various spots and markings on each side, and 

 ending in a transverse angulated, black, irregular bar near the hinder 

 extremity : the surface of the al3domen from this bar to just above 

 the spinners is distinctly paler than the rest ; sides deep brownish, 

 and underside like the upper in colour. Genital aperture small, 

 but of distinctive form. Spinners short, of about equal length, 

 compact, and similar in colour to the underside. 



This Spider is allied to S. dufourii Vins., and also to ^. mada- 

 f/ascariensis Yius., but may be easily distinguished from the latter
