minute dark specks. The middle of the upper side shows the 

 ordinary four impressed spots in a quadrangle longer than broad, 

 and whose fore side is shorter than the hinder side. Between 

 these spots and the spinners are several slender, broken, angular 

 lines or chevrons, formed by some of the dark specks mentioned 

 above. In an immature female there appeared something of a 

 more or less regular whitish j)attern along the middle of the 

 upper side, with yellow -brown lateral spots and markings. 

 Probably this pattern would become more definite in a series of 

 examples. The underside is of a pale, dull whitish hue. The 

 genital aperture is small, but characteristic. 



An adult male measured a little over 2 lines in length. The 

 cephalothorax of this sex is flatter and the abdomen is more 

 rugulose, but in general colours, markings, and other respects it 

 closely i-esembles the female ; its legs,- however, are much longer. 



Palpi similar to the legs in colour. Cubital and radial joints 

 equal in length ; the latter has a veiy small pointed apophysis at 

 its fore extremity outside ; the digital joint is very naiTOw, scarcelv 

 broader than the radial. The palpal organs very simple and 

 inconspicuous. 



An adult male and female and an immature female were found 

 among bananas imported from the Canary Islands, and kindly 

 sent to me by Mr. H. Speyer.

Genus Euprosthenops Pocock. 



(This generic name was substituted in 1897 by Pocock foi- 

 Podojihthalina De Brito Capello, preocc, 1866.) 



Euprosthenops prospiciens, sp. n, (Plate L. figs. 38-40.) 



Adult male, length 7 lines. 



Cephalothorax longer than broad ; lateral marginal impressions 

 at caput strong, lower corners of caput produced into two strongish 

 obtuse prominences, each bearing an eye. Cephalothorax I'ather 

 flattened, the caput and thorax being on the same level ; the fore 

 part of the caput sloping forwards to the prominent corners ; the 

 normal grooves and indentations are strong ; colour yellow-brown, 

 narrowly margined with black, and with a broad dark yellow- brown 

 longitudinal band on each side of the median line, and a narrower 

 lateral band between it and each lateral margin, moi'e or less 

 densely clothed with short adpressed white hairs, which also run 

 more or less through to the corner prominences ; these last are 

 strongly margined with deep reddish brown on their inner sides. 



Eyes in two groups : four behind form a large quadrangle, the 

 anterior side of which is much the shortest, and four in front (of 

 which the two antei'ior ones are very wide apart at the extre- 

 mities of the corner prominences) of the caput, and the posterior 

 ones near together in front of the fore eyes of the hinder group,
