292 SPECIFIC DESCRIPTIONS OF 



The upper side is furnished with numerous strong 

 nearly erect black bristles. 



The labium has a row, of bristles only, at its apex. 



The markings of the cephalothorax in the female 

 are very nearly like those of that sex in iV. Mauderst- 

 jerna ; the tapering orange yellow band, however, 

 behind the eyes appears to be rather bolder, as in 

 that species this band also is faintly traceable quite 

 to the hinder thoracic margin. The inner corner of 

 the base of the maxillae, in both sexes, has several 

 minute tooth-like black spines. 



The form of the cephalothorax in the female differs 

 from that of the male ; in the latter sex (male) it is 

 narrower before and rather rounded behind ; in the 

 former sex (female) it is broadest before and more 

 distinctly hollow-truncate behind ; the caput is also 

 rounder and more elevated. In the female the tarsi 

 and metatarsi of the two first pairs of legs have close 

 set brush-like hairs beneath ; these are wanting in the 

 two hinder pairs, and also almost entirely wanting 

 on the two first pairs in the male. 



Various other characters, both peculiar and diffe- 

 rential, are noted in regard to this species by M. 

 Simon (I.e.). It is to be regretted that this pains- 

 taking observer did not note more exactly the form 

 and type of its nest ; from his description of it, how- 

 ever, it appears to be branched, but whether the door 

 is of the wafer or cork tj^pe, or whether it has an inner 

 door or not, is not mentioned. 



Habitat. Corsica.
