is broad p3rriform, as long as it is wide anteriorly, and with 

 the usual 3 circumanal hairs. 



Systematic position. As lias already been point ed ont by 

 OuDEMANS, this species is intermediate to C. cervus (Kram.) 

 and C. nemorensis (C. L. Kock). The two latéral incisions in 

 the dorsal shield do not meet; it agrées in this respect with 

 C. cervus, but the incisions do not curve so much backwards 

 . as in that species. As a matter of fact, if the incisions were to 

 meet, the separating line thoy would form woiild be of exactly 

 the same configuration as in C. nemoreyisis and C. Kochi. 



In one respect, however, C. transisalae difïers from the 

 species mentioned above ; the chela mandibuli is narrow, 

 with straight jaws provided with few and small teeth. 



RELATION OF CYRTOLAELAPS TO GAMASELLUS 



The genus Gamasellus was established by Berlese as a sub- 

 genus of Cyrtolaelaps. Subsequently, he raised it to a genus. 

 In a previous paper I pointed out that in the female of 

 G. {?) S'piricornis (G. et R. Can) Berl. (1910, p. 427) the meta- 

 sternal shields are fusedwith the sternal shield, a charac- 

 teristic which is presumeably also possessed by the other species. 

 This discovery of distinct metasternal shields in the female 

 of C. transisalae indicates both gênera being still less closely 

 related than has been the opinion prevailing hitherto. 



PACHYLAELAPS Berl. 

 P. pectinifer (G. and R. Can) Berl. 



(Fig. 69-74). 



To this species I refer with some hésitation a single female. 

 Berlese's diagnosis in his great work « Acari ; M3rriopodi et 

 Scorpiones » is not detailed enough to allow of any absolute 

 certainty of identification. On the other hand, there are several 

 points which strongly argue in favour of both being identical
