than each is from the extreme eye (mentioned before) on its side ; 

 the two centrals of the front row are also nearer to each other than 

 each is to the one next to it on its side. 



The legs are long, rather slender, of a yellowish-brown colour, the fe- 

 mora being strongl)' marked longitudinally with a much darker colour 

 than the rest, nearly as dark as the sides of the cephalothorax ; they 

 are furnished sparingly with hairs, and with spines of different lengths ; 

 their relative length appeared to be 2, 1, 4, 3. 



The jjalpi are moderately long and similar in colour to the legs, the 

 hinder part of the humeral joint being darker than the rest; the 

 radial and cubital joints are short ; the former is the shortest, and has 

 a small, pointed, curved apophysis beneath its fore extremit)^ rather 

 on the outer side ; the digital joint is rather large, of an oval form, 

 and longer than both the radial and cubital joints together : the palpal 

 organs are very simple, and not pi'ominent ; they have a rather strong, 

 curved, sharp-pointed, corneous process curving round their fore extre- 

 mity, the sharp point being on the outerside. 



The /a/ces are moderate in length and strength, of a subconical form, 

 and (looked at in profile) directed backwards ; they ai-e, as also are 

 the maxillce, labium, and sternum, of the same colour as the cepha- 

 lothorax. 



The abdomen is oval, rather broader behind than in front, where it 

 is truncated, and projects over the base of the cephalothorax ; the 

 colour is a dark pur])lish yellow-brown; and on the fore half of the 

 uj)perside is a large oblong white |)atcli, along the longitudinal centre 

 of which is the ordinary characteristic marking, of a larger size than 

 usual, its sides irregularly notched or dentate, and its colour as 

 dark as that of the cephalothorax ; towards the hinder part of the 

 sides of the abdomen are a longitudinal series of three curved, narrow, 

 white bars, each one decreasing in length and strength behind the 

 other ; between these, along the middle of the hinder part of the 

 abdomen are three curved, pale greyish, obscure, angular bars or chev- 

 rons ; immediately behind the oblong white patch on the forepart, 

 and in a transverse line, are two largish circular depressions of a 

 deeper hue than the rest of the surrounding surface ; the underside 

 is rather paler than the upperside, and has some obscure, pale, lon- 

 • gitudinal, broken, parallel lines; the spiracular plates are cream- 

 coloured. 



Probably the females and immature, or lately matured, males 

 will 1)0 found to approach very nearly in colour and mai'kings to 

 P. aureolus and P. ccspiiicolis. 



Two adult males were found by myself on low plants at Corfu 

 in. May 18G5.
