MR. STANLEY HIRST ON 



few modified and sensory hairs. Dorsally near the apex of the 

 tarsi there is a curved hair or seta with the end enlarged, being- 

 flattened and pectinated. There appeal's to be only one of these 

 hairs on the anterior tarsi, but there are two on the third tarsus. 

 There are several short, stilf curved rod-like sensory hairs 

 (sinneskolben) at the distal end of the anterior tarsi ; four of 

 these sensory sette are also present on the penultimate segineut 

 of the first leg, two dorso-lateral ones posterioi'ly and another 

 anteriorly, and one ventral in position. Besides the short distal 

 sensory setae on the second tarsus, there is also one rather near 

 the proximal end ; whilst there are two on the penultimate 

 segment of this leg. Tarsus and also the penultimate segment of 

 the posterior legs each usually with a slioi-t, stiff sensory seta near 

 the proximal end, but that on the penultimate segment of the 

 fouith leg may be absent.

jSTote. — The finer structural details are not all given in 

 Canestrini's and Berlese's figures of A. latus, so tliat I have some
