conoid hairs (c', Fig. 21) are probably only highly 

 specialised feeling bristles, and are found in greatest 

 number at the extremity of the antennae. Each 

 antenna carries no less than six distinct structures, 

 viz., two forms of hairs not sensory on the scape and 

 upper joints, the ordinary sensory hair, the conoid 

 bristle, the elliptic discs, and, lastly, another structure 

 about to be described, and which is extremely likely

 minute holes, from ^Voin. to r^^m. across, each 

 surrounded by a bright reddish ring. The micro- 

 scopist had better choose the antenna of a youn<r

 proverbially are— he will be as likely to lose his temper 

 as find the object. It is situated at the lower part 

 and outer side of the last six or seven joints of the 

 fiagellum, but is found in greater abundance as we 

 get towards the end, the terminal joint carrying a
