COMPARISON BETWEEN P. BREVISPINOSUS AND 



Cyrtolaelaps mucronatus (G. et R. Can). 



In the genus Cyrtolaelaps Berl., C. mucronatus (G. et R. Can) 

 Berl. occupies in several respects an isolated position. 



Thus the body is broad pyriform in outline, with the greatest 

 width far back, in the posterior third, consequently quite diffé- 

 rent from that of the other species, in which it is broadest in 

 the middle, or of almost equal width for a long way. Further- 

 more, ambulacres I hâve membrane, and the 9 chela 

 mandibuli is very narrow, more like that of the genus 

 Zercon than of Cyrtolaelaps. 



As only the female of C. mucronatus was known, it was 

 impossible to ascertain whether it was rightly referred to 

 Cyrtolaelaps, or not. The fund of both sexes of P. brevispinosus 

 throws some light on this question. 



A comparison between the female of P brevispinosus, and 

 that of G. mucronatus (1), ehcits the folio wing facts. 



The shape is identical in both; the shape of the two dorsal 

 shields is the same, as is also the configuration of the Une of 

 démarcation between the shields. The anterior dorsal shield 

 of both has anteriorly a pair of small bristles. The shields of 

 P. brevispinosus Tgdh hâve each two pairs of hairy bristles 

 (fig. 75 a), whereas Berlese only mentions and delineates one 

 pair on each. The other two pairs are, however, smaller and 

 less conspicuous, as they dot not project beyond the margin of 

 the body, and hâve very likely been overlooked by Berlese. 

 G. and R. Canestrini, on the other hand, hâve noticed the
