Subfamily Diplurin^. 

 Genus Chenistonia Hogg. 



Chenistonia tepperi, nov. sp. (Plate XIII. fig. 13.) 



Oeplialothoiux dull reel-brown (yellower bi'own in apparently 

 rather younger specimens). Mandibles dark I'ed-bi'own, with pale 

 yellow downlying hairs and longer upstanding bi'Own. Lip, 

 maxiUa?, sternum, and coxas dark red-brown, with upstanding 

 bi'own hairs only. 



Legs and palpi paler red-bi'own, with long brown hairs, scopulfe 

 yellowish grey. 



Abdomen yellow above and below, with short do"\\ailying, almost 

 golden haii'S and a few longer and browner. The cephaloihorax is 

 nearly one-fifth longer than broad, slightly rounded at sides, a 

 third part narrower in the front and rear than in the middle, and 

 rising in a moderate slope from in front of a straight thoracic 

 fovea two-thirds of the length of the cephalothoiux from the 

 anterior end. 



The eye-space is on a somewhat rectangular raised prominence, 

 which begins at a distance the diameter of the front middle eyes 

 away from the margin of the clyj^eus. The fi'ont I'ow of eyes is 

 slightly procui'ved. The median pair, barely theii- diameter apait 

 and only one-third from the neai-est point of the latei'als, are two- 

 thirds the diameter of the latter, and stand on black shiny rings. 

 The real' laterals, as far from the front laterals as the latter from 

 the front median, are only slightly larger than the front median. 

 The rear medians nearly touching the laterals are about as long 

 as the front median, half their diametei- from them ; the rear row 

 is distinctly recurved. 



The mandibles are stout and rather longer perpendicularly than 

 they are horizontally, the bristles on the fore part distinctly 

 hardened, the fangs long and well curved. A row of eight large 

 teeth on the inner edge of the falx-sheath and five small in the 

 intermediate space at the lower end. The %_> is slightly 

 broader than long, hollowed in front and without spines. The 

 maxilke have a rather broad rounded base, are hollowed round 

 the lip, and straight in front. They are thickly covered with 

 spines ovei- half the breadth of the basal area. 



The stermcm is a broad oval, slightly convex, and having the 

 sigilla all marginal. The legs are moderately long and stout; 

 the tarsi of all four pairs have a thick scopula, as also the meta- 

 tarsi of the front two pairs. None of the tarsi but all the 

 metatarsi are bespined, and two pairs of short spines on patella iii. 

 All the patellae have a broad longitudinal bai'e streak. The 

 superior tarsal claws have about 8 or 10 pectinations in each of 

 their two rows. The third claw short and bare and nearly 

 straight. 



The abdomen is oval, thickly covered with short furry hair 

 intermixed with a few long single ones. The inferior spinnerets 

 are close together-. The superioi', tapering from the base, are one
