482 ME. H. E. HOGG ON SPIDERS 



at the sides and rear, slightly marked depressions separating the cephalic from the 

 thoracic part. There is a deep longitudinal fovea at the upper part of the rear-slope. 

 The nearly perpendicular clypeus narrows from the insertion of the mandibles to the 

 rear of the eye-space. 



The rear-row of eyes is recurved, the lower edge of the laterals being slightly 

 below the level of the upper edge of the median, their long diameter is the same as 

 that of the median, and they stand on black protuberances. The median pair have 

 black rims, are less than one-third their diameter apart, and twice that distance from 

 the laterals. The median eyes of the front-row are protrudent and, including the black 

 rims, three-fifths the diameter of the rear eyes and two-thirds their diameter away 

 from same. They are larger than the side-eyes and half as far away from them as 

 from one another. 



The clypeus is about as wide as the median eye-area is long. 



The mandibles are geniculate at the base, have long powerful fangs, and four large 

 teeth on the inner falx-margin. They are furnished with long bristly upstanding hair 

 at the base and front end, and short recumbent hair in the middle. 



The lip is as broad as long, widest in the middle, truncate in front, convex, and 

 covered with long bristly hair, and rather more than half the length of the maxillae. 

 The latter are widest at the anterior end, rounded at the back, narrowing to the base, 

 and are thickly covered with iipstanding bristles. 



The sternum is broad shield-shaped, truncate in front, rounded at the sides, obtusely 

 pointed at the posterior end, where the coxse are quite contiguous, and thickly 

 covered all over with long upstanding bristles. 



The abdomen is oval, straight in front, pointed at the rear end, twice as long 

 as its greatest breadth, which is at the middle ; the hair is close, smooth, and 

 short. 



The inferior spinnerets are contiguous at the base, conical, rather longer than the 

 breadth at the base, and have a short second joint. The superior, rather longer but 

 smaller in diameter, have a longer second joint. The epigyne is a convex transverse 

 protuberance, broadest in the middle, with two black depressions, one across each 

 side ; these are carried into a broad depression above marked at its sides with 

 a thin chitinous edging. 



The legs are long and strong, tapering to fine cylindrical tarsal and metatarsal 

 joints. The hair on the femoral and tibial joints is smooth and recumbent, longer and 

 more bristly on the metatarsal and tarsal. On the underside of the latter it thickens 

 into rather loose scopulse. The spines are long and powerful, one each side near the 

 base and one at the anterior end of the patellar joints. The superior claws have about 

 six pectinations, the inferior being smooth ; the latter are buried in a thick brush of 

 bristles. The second pair of legs is rather longer than the first as in Trechalea l^hor.,
