118 REV. O. P. CAMBRIDGE ON SOME NEW [Jan. 21, 



Fam. PODOPTHALMIDES. 



Nov. gen. Labdacus (nom. prop.). 



Eyes 8, unequal in size ; the four largest form a transverse curved 

 row on the summit of the caput, the curve directed forwards : in 

 front of and near to each of the lateral eyes of this row is another 

 minute eye, much paler in colour and therefore less easy to be seen ; 

 and in front of the two central eyes is a much shorter transverse row 

 of two eyes, near together and placed immediately on the lower margin 

 of the clypeus. 



Cephalothorax rather Thomisiform, broad, oval, truncated at both 

 ends ; caput elevated above thorax, and produced a little forwards ; 

 clypeus prominent. 



Abdomen elongate, tapering a little towards the spinners, and con- 

 stricted laterally at two points. 



Legs long, tolerably strong, relative length 4, 1, 2, 3 ; terminal (or 

 tarsal) claws 3. 



Maxillae strong, moderately long, broad, enlarged and rounded at 

 their extremities, and straight. 



Labium rather more than two thirds the length of the maxillae, 

 oblong in form, rounded at the apex, in the centre of which is a small 

 notch, and with the upper half enlarged on all sides in a sort of mush- 

 room shape ; this character of labium is frequently seen in Spiders 

 of the genus Melanophora (fam. Drassides}. 



Labdacus monastoides, sp. n. (Plate XII. fig. 3.) 



Female adult, length 4| lines. 



This remarkable Spider bears great resemblance to Spiders of the 

 genus Monastes (Lucas).. It is of a uniform yellow colour, the sides 

 of the abdomen (in the constricted parts chiefly) being suffused with 

 brownish red. 



The cephalothorax is broad, oval, truncate at either extremity, con- 

 stricted laterally on the margins at the junction of the caput and 

 thorax. Caput rather elevated ; clypeus broad and prominent ; 

 normal grooves and indentations moderately strong. 



Eyes 8 in number, and situated on black tubercles, in position 

 as above described; the two central eyes of the hinder row, which 

 embraces nearly the whole width of the caput, are nearer together 

 than each is to the lateral on its side, and the space which separates 

 them from each other is about equal to once and a half an eye's 

 diameter ; the interval between each of the fore centrals, which are 

 much smaller, is about equal to two diameters, while the space be- 

 tween each of them and the hind central eye nearest to it is rather 

 greater than that between the hind centrals ; those of the hinder 

 row are very nearly equal in size ; the laterals of this row have a side 

 aspect, and the tubercles on which they are placed are stronger than 

 the rest. 



Legs rather long, moderately strong ; those of the first and fourth 

 pairs do not differ much in length, the fourth being a little the longest; 

 they are furnished with hairs and spines; of the latter two parallel Ion-
