DIPhOPODA OF LIGURIA 521 



inferior angle ncuto and marked with two striae. On the rest of 

 the somites the longitudinal striae never attain tlie summit, 

 and only two or three are visil)le above the pores, inferiorly 

 the striae are complete, above they are incomplete. Tlie Irans- 

 verse sulcus is deep and beaded , with the areas in front and 

 behind it elevated; behind this sulcus there is a second faint 

 transverse sulcus. The pores are conspicuous, well behind the 

 principal sulcus, but only just behind the second; they are si- 

 tuated very high on the si<les. The anal lergite angled behind , 

 covering but not surpassing the valves, furnished posteriorly with 

 a series of long setae; valves not compressed, hirsute behind. 

 Legs hairy, setose. 



c/. With the anterior pair of legs small and hook-like ; the 

 posterior angle of the mandible produced, the legs not padded. 



Number of segments 45. 



Length about 14 mm.; width 7 mm. 



Locality: Venice, one cT specimen only was taken. 



Owing to its small size, slender build , the absence of eyes 

 and the absence of longitudinal striae on the dorsal surface of 

 the body, as well as in the deepness of the transverse sulcus, 

 this interesting new species reminds one forcibly of Blaniulus. 

 The anterior feet of the c/", however, resemble those of a true 

 lulus. 



This species is thus apparently to be referred to the genus 

 Mesoiulus of Berlese. It differs from M. paradoxus of Berlese 

 from Padova in that the segments are not striate above, those 

 at the anterior end of the body being only striate at the sides ; 

 moreover the pores are situated higher on the sides of the body, etc. 



6. Diploiuliis nanus (Latz.) 



Vitznau and Lucerne. 



7. I>ij>loivilus loiidiiiexisis (Lkaoh). 



Basel, Lugano. 



This species does not appear to extend into Italy.
