DII'LOPODA OF LIGURIA 511 



lightly emarginate; the posterior border of the median dorsal 

 sm-face lightly emarginate, but without a transverse subgranular 

 ridge in front of it. The seliferous luberdes very small and the 

 setae very short, tlie tubercles spaced about as in tiie following 

 species. 



The anterior legs a little thickened. The infero-lateral border 

 of tlie tergite of the 7^'^ somite mesially bluntly dentate. 



The internal pieces of the anterior pair of copulaiory feet 

 long, stout and contiguous at tlie base, slender and diverging 

 distally, strongly geniculate, hooked at the apex: the lateral 

 piece composed of two slender erect branches, the anterior of 

 which is considerably tlie longer of the two and is rectangularly 

 curved at its distal extremity, the posterior is only lightly 

 curved ; the posterior pair of copulatory feet are small , fuscous 

 and apparently resemble tolerably closely those of A. meridionale. 



Length up to about 18 mm. 



Locality: Busalla. 



Differs from the following in its larger keels, shorter setae, 

 smaller tubercles, copulatory apparatus, etc. Apparently some- 

 what nearly related to A. meridionale of Fanzago (cf Latzel, 

 loc. cit. p. 177. pi. VIII, fig. 95 j, but differing at least in the 

 form of the copulatory feet.

iFig. 3 -3a) 



5 . Colour llavo-brunneous, the dorsal surface, excepting the 

 keels, subfuscous, antennae fuscous , legs Havous with the distal 

 extremity infuscate. 



Antennae much longer than the width of the body. Eyes ma- 

 nifest, triangular, composed of about 25 ocelli, arranged in about 

 6 longitudinal rows. 



Dorsal surface of each segment finely shagreened, mesially 

 lightly convex, posterior margin lightly concave, w'ith a transverse 

 su})-granular mesially interrupted crest just before it. The keels 

 moderately large, horizontal, rising high on the lateral surface.
