CHILOPODA OF LIGURIA 67 



21. HiirLa,ii.ta.x*iuiii (Stigmatogaster) g-racile, Meinert. 

 Monaco, Borzoli, Portofino. 



22. Hinxantax'ium. g-estri, sp. n. 



Length 110 mm.; 137 pairs of legs. 



Of moderate size ; much attenuate anteriorly, slightly so po- 

 steriorly. 



Legs in the middle of the body much thicker than those in 

 the anterior and posterior portions. 



Antennae long and somewhat slender, attenuate. 



Cephalic plate wider than long and a little overlapping in 

 front the flexed maxillary feet. 



Tergites smooth ; in the posterior portion of the body obsoletely 

 bisulcate. 



Sternites in the anterior half of the body, except the first, 

 marked behind the middle with a rounded porous area; on 

 each side of this area the plate presents an irregularly but 

 only slightly crumpled appearance ; in the posterior half of the 

 body the sternites are smooth and without a porous area ; 

 none of the sternites marked with lateral marginal depressions. 



No sclerites intervening between the tergites and the tracheal 

 sclerites. 



The last tergite smooth and not sulcate. 



The last sternite conspicuous, triangular, posteriorly truncate 

 and marked with a deep median longitudinal depression. 



The posterior pleurae inflated, not wrinkled as in e. g. H. ga- 

 hrielis, but smooth and conspicuously covered above and below 

 with larger and smaller close -set but distinct pores. 



Anal legs slender and elongate. 



A single female specimen from Monaco at an altitude of 

 300 ft. on the hill-side behind the town. 



In possessing a rounded porous area on at all events some 

 of its sternites this species approaches H. hispanicum and ff. me-
