1907.] NEW AND LITTLE-KNOWN SPIDERS. 825 



Abdomen rather more than twice as broad as long, of a some- 

 what transverse oblong form ; its fore margin strongly emarginate ; 

 its upper margin is surrounded with tubercular conical or sub- 

 conical prominences of different sizes, all, excepting those on the 

 hinder margin, more or less confluent, the largest are on the 

 lateral margins ; the upper surface also has other similar promi- 

 nences symmetrically disposed. There are also on the upper side 

 numeroiis orange-red round sigillse, each with a dark blackish or 

 deep red-brown pupil ; these sigillas form a submarginal border 

 and a sj'mmetrical pattern in the middle ; a small symmetrical 

 pattern of minute roundish cream -yellow spots of diffei-ent sizes 

 and margined narrowly with black occupies the centre of all. The 

 whole upper sui'face is dull yellowish, with a large very irregular 

 jet-black patch on each side of the hinder part, which does not, 

 however, obscure the orange-red sigillfe. The under side is dark 

 yellow-brown on the hinder half, the anterior portion being black 

 covered with small yellow irregular spots and scratch-like markings. 

 The genital aperture is of simple but characteristic f oi'm. Spinners 

 short, compact, situated within a circular slightly raised rim. 



Sternum shield-shaped, longer than broad, with eminences 

 opposite to the insertion of the legs. Colour dark reddish yellow- 

 brown. 



Received from Old Calabar, whence it was kindly sent to me 

 by Mr. Holland, of the Botanic Gardens, Old Calabar. 



Fam. Thomisid^. 

 Genus Thomisus Walck. (ad partem). 



Thomisus malevolus, sp. n. (Plate L. figs. 32-34.) 



Adult female, length 9*05 mm. 



General colour pale yellow with white markings and mottlings. 



The cephalotho7-ax has on each side a broad longitudinal band 

 throughout its length of yellow-brown ; the caput, which has the 

 usual horned shape above, is rather symmetrically streaked with 

 lines of white granvilosities and suffused with white at the occiput 

 behind the eyes ; and the ocular area is white, margined with a 

 strong black line, forming a large triangle, whose apex (in front) 

 forms an acute angle almost touching the lower margin of the 

 clypeus. This triangle is subdivided by two short curved black 

 lines, running through the fore-central eyes and uniting at the 

 middle of the hinder side of the triangle, which runs to the 

 extremity of each horn. The height of the clypeus equals half 

 that of the facial space. 



The eyes are small, widely spread, occupying the whole width of 

 the black triangle above described. Those of the fore-central 

 pair are nearer together than to the fore-laterals, while those of 

 the hind-central pair are rather further apart than from the hind- 

 laterals ; these last are placed beneath the tips of the horns of the 

 caput, and are not easy to be seen.
