o 



Australia and the Malay archipelago, by which latter alone 

 there would seem to be any existing connexion between Ceylon 

 and Australia ? Are there any and what known insects common 

 to Ceylon and North Australia? 



Family Colophonid.es. 



Nov. gen. Colophon (nom. propr.). 



Characters of the Genus* 



Cephalothorax oblong-oval, moderately convex above, with 

 the normal indentations strongly marked. Clypeus long, im- 

 pressed, and prominent. 



Eyes eight, unequal in size, closely grouped in a transverse 

 oblong-oval figure on a slight tubercular elevation, towards the 

 fore part of the caput ; the two largest occupy the centre of 

 the group in a transverse line ; and three others on either side 

 form a curved row, the curves directed outwards. 



Legs moderately long, relatively 4, 1, 2, 3, strong, parti- 

 cularly those of the first and second pairs. Tarsal claws strong, 

 three in number, the two superior ones strongly pectinated. 



Falces small and rather projecting ; fangs folding down over 

 the inner edge of the falces. 



Maxillai moderate in length, broad and strong near their 

 base, somewhat bluntly tapering from the insertion of the 

 falces to their extremities, strongly inclined to the labium, and 

 broadly and obliquely impressed in a transverse direction on 

 the middle of their outer surface. 



Labium long, rather broadest near the middle, where it is 

 broadly compressed, and whence it tapers gradually to the 

 apex, which is drawn out into an obtuse point to the same 

 length as the maxilla?. 



Abdomen elongate-oval, joined to the cephalothorax by a 

 strong and distinct pedicle. Spiracular openings four in 

 number, the two extra ones placed immediately in front of 

 the usual pair. Spinners six, those of the superior pair 

 largest and longest ; and beneath them the remaining four, of 

 equal length, form a straight transverse row. 



Colophon natalensis, n. sp. Plate XVII. fig. 1. 



Adult male, length 4 lines. 



The whole of the fore part of this spider is of an orange- 

 yellow colour, that of the abdomen being a pale dull straw- 

 yellow. 



The cephalothorax is very thinly clothed with short hairs ; 

 the legs are tolerably furnished with hairs, but no spines : the
