off from the thorax by a contiuuous and tolerably strong constriction. Thorax 

 very tumid or gibbous on the upperside behind; hinder slope short, abrupt, its 

 profil line slightly incurved. The posterior end of the thorax drawu out in a 

 sheatUike form to receive the pedicle connecting it with the abdomen. Eyes 

 unequal in size, and forming a large crescent; they are placed in two slightly 

 cuiTed rows, the cuiTe of the anterior row directed forwards, that of the 

 posterior backwards, though this latter row is the longest and nearly straight. 

 The fore-central pair are the largest, the rest subequal, the hind-centrals rather 

 the smallest. The four central eyes form a square. The interval between the 

 eyes of the fore-central pair is equal to a diameter, and that between the hind- 

 central pair is double that between each and the hind-lateral eye next to it. 

 The hind-central eyes are on the flat surface of the caput, the rest on slight 

 eminendes. The eyes are all dark-coloured. The clypeus is prominent below, 

 and its height is equal to one and a half diameters of one of the fore-central eyes. 



Falces moderate in length and strength, their profile strongly cuiTed. 

 Legs moderably long,, not very unequal in length, slender 4, 1, 2, 3; the two 

 posterior pairs strongest; terminal tarsal claws 2? (owing to a dense claw-tuft 

 these cannot be satisfactorily made out). They are armed with a few rather 

 long slender spines, some of which are arranged in pairs beneath the tibiae 

 and metatarsi. The coxae of the fourth pair are contiguous. 



Palpi long; digital Joint somewhat clavate, its length rather exceeding 

 that of the radial and cubital joiuts together. 



Maxillae strong , sligthly divergent at the Upper extremity , and obtusely 

 and rather roundly truncated. 



Labium short, less than half the length of the maxillae ; the outer margins 

 curved and the apex truncated. 



Stenium heart-staped. 



Abdomen short oval broader and deeper behind than before, connected by 

 a short but distinct pedicle with the thorax, the pedicle arising from a stört 

 sheath-like prominence on the abdomen. Spinners short, strong, compact, those 

 of the superior pair two-jointed, the terminal Joint very short. Immediately in 

 front of the Spinners is a rather large, conspicuous, transverse opening protected 

 by a prominent lip, and no doubt leading to a spiracular organ) fuliginosus
