transverse pores in front, the anterior crest, where the 2nd bristle of the median 

 longitudinal row is inserted. 



The hairs (fig. 139) are more or less leaf-shaped, lanceolate and very 

 numerous, arranged as fig. 138 shows. 



Ventral side (fig. 140). Sternal shield with distinct, polygonal tex- 

 ture and two pairs of narrow pores, one pair near the anterior margin on the 

 inner side of the anterior pair of hairs, the other pair about halfway between 

 the 2nd and 3rd pair of hairs. 



The sternal shield is pentagonal, longer than the width between coxae II, 

 with concave posterior margin, extending to the middle of coxse III. It is

fused with the endopodial shields of legs II, and contiguous with the anterior 

 ends of the endopodial shields of legs III which are free, as are also those of 

 legs IV. 



The metasternal hairs are inserted on a level between coxai III and IV 

 and not surrounded by any metasternal .shield. 



The geniti-ventral shield is very remarkable in so far that is has 

 numerous, fine lines, running more transversally near the posterior end but 

 further forwards longitudinally, forming elongated, polygonal areas. This is a 

 feature which distinguishes the genus Lcslaspis, but not Cosmolcelaps. The 

 present species can, however, not be referred to Lcelaspis, because the geniti- 

 ventral shield is not contiguous with the anal shield. The geniti-ventral shield 

 almost twice as long as its greatest width, projecting almost to the middle of 

 coxae III, its anterior half being tongue-shaped, with almost paralell sides, pos-
