1896.] AND LITTLE-KNOWN SPLDBBS. 1009 



Feidxa wallacii, sp, n. (Plate LII. fig. 2.) 



Adult female, length 3| lines ; length of abdomen 2| lines ; 

 width of abdomen slightly less than the length ; total width to 

 extremity of the lateral projections very nearly 8 lines. 



The whole of the Spider is of a dark rich reddish-yellow-brown 

 colour, the sigilliform markings on the abdomen being a little 

 darker than the rest. It is, however, quite possible that in life 

 there might be other tints and colours now lost by age and 

 desiccation. 



Although an unmistakably Gasteracanthid Spider, it seems to 

 me impossible to include this remarkable form iu any genus as yet 

 characterized. 



Found by Dr. A. E. Wallace at Sarawak many years ago, and 

 obtained from the collection of the late Mr. Wilson Saunders. 

 It is only lately that I have been able to ascertain (from 

 Dr. Wallace) that he was the captor of this Spider, and in the 

 locality mentioned. 



Labdaous, Carabr. 



Labdaous monastoides, Cambr. (Plate LII. fig. 3.) 

 The female of this Spider (described and figured, P. Z. S, 1873, 

 p. 118, pi. xii. fig. 3) was from Rio Grande, Brazil. The male 

 now described resembles the female in general characters, colours, 

 and markings. The length is 5| lines, that of the abdomen 

 being 3| lines. 



Geplialotliorax longer than broad, oval, truncated at each end ; 

 rather flattened above ; profile-line to the posterior eyes level, 

 excepting a slight depression at the thoracic junction ; height of 

 clypeus less than half the diameter of one of the fore-central eyes ; 

 lateral marginal impressions at the caput moderate. Colour 

 brownish yellow, with a black marginal line and dusky converging 

 bars. 



Eyes greatly unequal in size, in three widely separated groups, on 

 black tubercular eminences. The lateral pairs with the hind- 

 central pair form a transverse curved line, whose convexity is 

 directed forwards. The hind-lateral eye is the largest and seated 

 on the outside of a strong hemispherical prominence, at nearly an 

 eye's diameter from the fore-lateral, which is the smallest and 

 placed in front of the same eminence ; the hind-centrals are 

 nearly, if not quite, as large as the hind-laterals, they are rather 

 more than a diameter's distance apart. The four centrals form a 

 quadrilateral figure, whose length is greater than its breadth, and 

 its anterior side much the shortest. 



Legs long, moderately strong, 1, 2, 4, 3 ; colour yellow; armed 

 with spines, of which those beneath the tibisB and metatarsi of the 

 first and second pairs are long, strong, and placed in a longitudinal 

 series of 8 or 9 pairs beneath the tibiae, and 7 or 8 beneath the 

 metatarsi ; tarsal claws 3, springing from a small claw-joint,
