402 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [Juue 2, 



The terminal tarsal claws are two in number, minute, and without 

 any claw-tuft beneath them. 



The palpi are strong, rather long, of a dull blackish colour, and 

 on the inner side of the three la;:t joints (cubital, radial, and digital) 

 there are several longish strong spines pointing inwards ; when the 

 palpi and fore legs are drawn back in an attitude of defence, these 

 spines form a sort of chevaux-de-frise over the fore part of the 

 caput, and are very conspicuous. 



The falces are rather long, strong, and a little inclined backwards 

 towards the labium ; they are of a yellow-brown colour, and furnished 

 with strong bristly hairs. 



The maxillce are rather long, strong, slightly dilated at their ex- 

 tremities, inclined towards the labium, and broadly and transversely 

 impressed across the middle. 



The labium is broader at the base than at the apex, which is round- 

 ed ; the colour of this part, as well as of the maxillae, is a pale dull 

 yellow-brown. 



The sternum is elongate-oval, sharp-pointed behind, truncate in 

 front, and of a darker colour than the maxillae and labium. 



The abdomen is joined to the cephalothorax by a distinct pedicle 

 or short wasp-like waist ; it is of an oblong-oval form, strongly con- 

 stricted over the middle of the upperside, the constriction marked 

 by a yellowish band clothed with whitish hairs ; the fore half of the 

 upperside is divided longitudinally by a broad yellowish band, the 

 remainder, as well as the hinder half, is dark blackish brown, the 

 whole clothed with scaly hairs reflecting similar metallic tints to those 

 on the cephalothorax ; on each side of the fore part is an ill-defined 

 oblique stripe or patch of a yellowish colour, clothed with whitish 

 hairs ; the underside is pale yellowish, but darker near the spinners, 

 and also clothed with iridescent hairs. The spinners are small, those 

 of the inferior pair being the strongest ; close above the anal tubercle 

 is a small compact tuft of white hairs. The genital aperture is small, 

 inconspicuous, and very simple in form. 



Two immature females of this beautiful and most interesting little 

 Spider were found at Hyeres, in France, in May 18/3, and kindly 

 given me by Mr. J. T. Moggridge, who has since found four other 

 examples (all females), one only being adult, at Mentone ; these also 

 Mr. Moggridge has kindly sent to me. The immature examples have 

 a paler hue and a more brilliantly purple and golden tinge than the 

 adult ; the spines on the fore legs and palpi are exceedingly charac- 

 teristic. 



Genus Phrurolithus, C. Koch. 



Phrurolithus gracilipes (Blackw.). (Plate LII. fig. 27.) 



Drassus gracilipes, Bl. Ann. & Mag. Nat. Hist., Oct. 1863. 

 Drassus romanus, L. Koch, Die. Arachn.-Fam. der Drassiden, 

 p. 225 (18C6). 



An immature male of this Spider, from near Lisbon, was described 

 as a Drassus by Mr. Blackwall (loc. cit. supra), and an immature fe- 

 male by Dr. L. Koch, three years later, from Rome, as a Phrurolithus.
