Neiv South African Spiders. 101 



FAMILY BAEYCHELID^E. 

 GEN. HAEPACTIEELLA * Pure. 

 1. HARPACTIEELLA HELENA n. sp. 



Specimens. 2 ad. $ $ (types; No. 11710) and many adult ? $ 

 and young from Stompneus, St. Helena Bay, Malmesbury Division,, 

 collected by Mr. J. E. C. Goold in May and June, 1902. The adult 

 $ 3 were found in May. 



$ 3 . Colour as in H. treleaveni Pure. (Trans. S. A. Phil. Soc., 

 r. 11, p. 341, 1902), except that the 2 spots between the posterior 

 lung-books are absent ; under side of sternum and coxae pale 

 ochraceous to greenish yellow. 



Carapace as long as the metatarsus and i of the tarsus of fourth 

 leg and as the tibia and f of the metatarsus of first leg. 



Bastellum composed of fine setae. 



Legs. Tibia of first leg 4 times as long as high in the middle, 

 very distinctly longer than the metatarsus and also than the distance 

 from the centre of the fovea to the anterior margin of the carapace ; 

 the metatarsus lightly but distinctly curved, its length almost equal 

 to the distance from the fovea to the anterior margin of the ocular 

 tubercle. Spines of legs as in treleaveni. First leg (including the 

 coxa) much shorter than the fourth (by nearly the length of the 

 fourth tarsus). Scopulae as in treleaveni. 



Pedipalps. Palpal organ with the spine slender and terete, a little 

 longer than the bulb, the distal part filiform and curving outwards. 



Posterior spinners longish, the apical segment (seen from below) 



* This genus was originally placed in the TlierapliosidcB on account of the feeble- 

 ness of the rastellum, which generally consists of rather slender setas in the <j , but 

 of stiff and spiniform seta and frequently also some slender spines in the ? . It is 

 closely related to Brachionopus Poc., from which it differs in the stronger develop- 

 ment of the scopulas of the 2 anterior pairs of legs. These scopulas in the ? are 

 dense and broad, extending at least half-way up the sides on the tarsus and distal 

 half of the metatarsus, so as to be plainly visible from above. They are quite entire, 

 and that on the metatarsus is quite as long as that on the tarsus. The scopula of 

 the fourth tarsus is imperfectly or more or less distinctly divided along the middle 

 by a row or narrow band of fine black setae in some of the species (including the 

 type), but in domicola n. sp. it is divided by a broader band ; that of the third 

 metatarsus may be finely divided or entire. The labium bears from 10 to over 30 

 apical granules in 2-4 rows, and the maxillaa have a large patch at the base. The 

 sternum is oval, and 1-^ longer than broad. The claws of the legs are not toothed 

 (in the first pair). The distance of the ocular tubercle from the anterior margin 

 varies from -| to over J of its length.
