512 R. I. POCOCK 



the posterior Ijorder straight and directed obliquely forwards and 

 outwards, the posterior angle produced, subdentate, the anterior 

 angle nearly rectangularly rounded, the lateral border defined 

 by a groove which curves anteriorly in front of the anterior 

 setiferous tubercle ; the sctiferous tubercles moderately large , 

 the distance between the one on the dorsum and the anterior 

 of those on the keels about twice as great as the distance be- 

 tween those on the keels; the setae tolerably long. 



d^. Anterior legs thickened. Dorsal surface much flatter in 

 appearance owing to the larger size and upward tilting of the 

 keels. Inferior edge of the 7^'' tergite angled; copulutory feet 

 with prominent apices, the internal sclerites of the anterior pair 

 approximated , robust , not particularly elongate and obscurely 

 divided at the apex, with an external longer compressed process, 

 and an internal shorter one, the external brandi is long, slender 

 and mesially geniculate, its distal half projecting inwards, the 

 apices of the two being capable of crossing beneath tlie internal 

 sclerites ; the posterior pair short pale coloured sub-laminate and 

 curved. 



Length up to about 13 mm. 



Locality : Busalla. 



This species in many of its characters is almost intermediate 

 between the preceding two, ^4. athesinum and A. doriae. 



The keels are larger than in athesinum, with the posterior 

 border produced, the tubercles are smaller and the setae shorter, 

 moreover the copulatory feet of the two species are very ditie- 

 rently constructed (cf Latzel's fig. of this apparatus in athesinum). 



In some points it seems to resemble A. canestrinii of Fedrizzi, 

 but is different so far as can be decided from Berlese's figure 

 of this species, which seems to show that the dorsal tubercles 

 are much larger than in A. gestri.
