every hiiir straight and ending in a knob ; on 13 is a similar tubercle, equal in 

 size to that on 2, and armed in same way, these two being the largest of the row ; 

 the other tubercles of these rows are small, equal, each with three hairs ; the 

 upper lateral rows run from 2 to 12, are small on 2, 3, 4, each with three hairs, 

 the rest minute, with two hairs ; below spiracles, from 2 to 13, is another row, 

 the three anterior ones small, with three hairs each, the others minute, with two ;
