played when placed under a power of 60 to 85 of the microscope, 

 and it required considerable and patient attention to master the 

 details presented. The varied appearance and wonderful display 

 of color has made it an object of attraction to all who have seen it. 

 Premising that the two applied maxillae constitute the antlia, the 

 extremity or terminal portion which forms the teretron is about 

 one-eighth of the whole length of the antHa. The description 

 subjoined is of the terminal of one of the maxillae, being one- 

 half of the teretron. 



TJ'pper and outer surface (fig. 1, 3, 4). Tip acutely pointed, 

 expanding upwards into three barbs, two of which, the first and 

 third, are placed on the outer side, whilst the second is intermediate 

 between them and next the line of junction of the maxillae. 

 From the barbed portion the terminal begins to expand, and on 

 its upper surface is presented in a line above the second barb a 

 curved projection terminating abruptly, shewing a sharp oval, 

 gouge-like edge ; the interior of the projection is sharply 

 hollowed out, and from it arises a large rounded tooth-like 

 process. From this point commence two or more rows of 

 thickly set setae, which continue the whole length of the antlia. 

 Above and on the outer side of the terminal is placed, diagonally, 

 a second process similar to that already described, whilst above, 

 in a line between the first and second, occurs the third. The 

 fourth is placed above and in a line alternating between the 

 second and third. The fifth is similarly placed in relation to the 

 third and fourth, and the sixth and last in repect of the fourth 

 and fifth. Each superior process is slightly larger than that 

 below it. At the base of the sixth process, in a slightly cupped 

 hollow, is a solitary long spine, whose office may be to prevent 

 the teretron being plunged too deeply into fruits to permit of 

 withdrawal. 



Under surface (fig. 2). Tip acutely pointed, expanding upwards, 

 then suddenly contracting, gives a sharp transverse ridge one-half 

 way up the barbed portion, which again expands upwards and 

 outwards, and forms a second sharp edged transverse ridge. 

 The remainder of the terminal is divided unequally into three 

 divisions, each of which presents a very strong sharp lancet-like
