Yet, making allowance for this fact, both figures agrée in 

 someessential respects. The sterniti-metasternal shield has 

 exactly the same shape in both, and close to its posterior 

 marqin there are two pairs of hairs. Furthermore, inguinal

 shape, and in the same places, viz. on a level with the 

 anterior edge of the ventri-anal shield; and the ventri-anal

 and there is also, in my opinion, very little doubt as to P. mucro- 

 natus and P. hrevis'pinosus being synonymous, a question which 

 Berlese will easily be able to settle.

 consequently from that of the nympha, which on the dorsal 

 si de exhibits a net-like texture formed by very low ridges.
