466 ME. H. E. HOGG ON SPIDEES 



The mandibles are as long as the front of the cepl\alothorax is wide, only slightly 

 convex, and covered with long, stout, bristly hair. On the inner side of the falx-sheath 

 are two very long, powerful, upright teeth followed by one median, one smaller, and 

 one quite small. On the outer are one large tooth and one smaller. There is a 

 thick fringe of long bristles on this, as also on the upper front-edge of the inner 

 margin. 



The lip is broader than long, convex, straight in front, widening to near the base, 

 Avhere it contracts into a straight-sided piece one-fifth of its total length. It has a few 

 lono- upstanding bristles over its surface and the usual fringe in front. It is one-half 

 the length of the maxillae, which are upright, convex, sloping from the highest point 

 to the outside as well as to the inside. They are broadest one-third of their length from 

 the anterior end, whence they curve on the outside to a base two-thirds the width of the 

 widest part ; the palpi are inserted about the middle of the outer side. The fringes 

 are lono'est at the apex and on the upper portion of the inner slope where they grow 

 (n'er the front surface, on the inner straight portion they are shorter and even in 

 leno-th. The under lip or rostrum is clearly seen projecting a distance above the 

 front lip nearly half the length of the latter and with a fringe still more strongly 

 pronounced. 



The sternum is shield-shaped, as broad as long, straight in front, pointed at the rear, 

 where it ends above the contiguous rear coxee. It is thickly covered with a growth 

 of coarse, upstanding, bristly hair. It is surrounded by a rather wide flat margin 

 between its edge and the ends of the coxse, most prominently in front of the third 

 and fourth pairs. 



The coxee of the legs are nearly bare, the other joints being thickly covered with 

 long, coarse, upstanding bristles and finer recumbent hair. On the underside of the 

 tibiee and metatarsi are three very long and powerful spines, and two long followed by 

 one short respectively. The tarsi and metatarsi are furnished with thick matted 

 scopulge, only broken by the beds of the spines. Underneath the femora are one long 

 spine and one shorter at the anterior end. 



The femoral joint of the palpi is curved on the inner side and broadest anteriorly. 

 There are long spines at the side of the tibia' joint, but no silvery-white patch 

 as on the legs, and scopula; on the anterior joint. The tibia is longer than the 

 patella. 



The abdomen is ovate, narrowest at the rear end, thick at the sides, and covered 

 with soft recumbent hair on the underside, less thick (or rubbed off) on the upper, 

 interspersed with long upstanding bristles. 



The inferior spinnerets are close together, conical, with a short hemispherical second 

 joint, and they spring from a bare chitinous base. The superior are longer and oval 

 in section, with a short cylindrical second joint. The epigyne is of the horse-shoe type 

 with the chitinous rim opened widest at the base.
