518 R. I. FOCOCK 



■ii. L>ii>loiuliis dicentniw, Latz. 



Portotino. 



32. I>iploiulixs •? IbroAvnii, sp, n. 



(Fiff. 6) 



Colour almost entirely pale ilavous, the black patches of pig- 

 ment marking the eyes very conspicuous, often a line of fuscous 

 spots on the side marking the pores, the anal somite sometimes 

 also lightly fuscous. 



/lead punctulate, tlie forehead marked with a transverse stria 

 as in Blaniulus ; frontal setae absent. Eyes indistinct, represented 

 by a patch of black pigment. 



First tergile laterally narrowed, its anterior border lightly 

 emarginate. The rest of the tergites smooth without setae, the 

 longitudinal grooves somewhat widely separated, abbreviated in 

 front and behind. The transverse sulcus moderately conspicuous, 

 apparently interrupted on a level with the pores. Pores large, 

 annulate, situated in front of the sulcus; in the anterior half of 

 the body, far removed from it, and lying close behind the border 

 of the preceding tergite ; in the posterior half of the body touch- 

 ing the sulcus from before. 



Anal somite punctulate, striolate, the tergite produced into a 

 long straight pointed caudal process, projecting far beyond the 

 valves; valves with margins compressed, trisetose. 



Legs short, slender, sparsely setose. 



(/". Anterior legs hook-like. Slenderer than 9 . 



N" of somites about 48. 



Length about 10 mm. 



Locality : Portofino. 



This new species falls into the section Allaiulus as defined 

 by Latzel. Of this subgenus the species to which it is most 

 nearly allied are moli/bdimts, pelidnus and nanus, agreeing with 

 them in the absence of frontal setae, the possession of a long 

 pointed tail. It may, however, without difficulty be recognized 

 by the forward position of its very conspicuous pores, its mar- 

 ji'inally compressed anal valves, etc.
