(fig. 25, c) three to eight in number, usually five to six. A few very long scattered 

 hairs are present on the cephalo-thoracic and free abdominal segments ; some well 

 within the margin, others marginal ; s)naU circular pores occupy the same regions, 

 and are much more numerous than the hairs, especially at the margins, but do not 

 extend far beyond the region of the anterior stigmata. Pygidium markedly but very 

 finely striate longitudinally over the whole area. Anal and vaginal orifice opposite 

 and central. Pores minute, circular, extending over the whole area, but forming four 

 bilateral linear bands ; margin (fig. 25, b) with seven elongate paraphyses or rod-like 

 thickenings of the body-wall ; one central, arising from between the median lobes ; 

 the outer pair often faintly indicated in old, highly chitinised individuals. Lobes in

two pairs, the median pair the larger, but all are relatively small and in some 

 individuals more or less rudimentary. Margin beyond the lobes with two or three 

 dentate prominences, the intervening spaces finely dentate ; three pairs of spinose 

 curved hairs beyond the last dentate process, the middle pair much the smallest and 

 often wanting. 



Average length, 1 mm. 



Larva. Antennae (fig. 25, d) of six segments, 1st much wider than the rest, 6th 

 nearly equal in length to the 2nd, 3rd, 4th and 5th together, and furnished with three 

 to four fine slender hairs, a subapical spinose hair and a very long apical one. Margin
