ASPIDIOTUS BEOMILI^], 87 



Female adult (PI. Ill, fig. 2), short, ovate, or almost 

 circular. At the period of gestation the body becomes 

 tumid and the segmentation indistinct. Colour varying 

 from very pale to dark mauve or dull purple. Pygi- 

 dium (PL IV, fig. 2) distinctly articulated with the 

 body. Circumgenital glands wanting. Subdorsal 

 groups of tubular spinnerets filiform, the longest ex- 

 tending beyond the vaginal opening; the connecting 

 dorsal pores in two short divergent series on either 

 side of the meson ; median group of tubular spinnerets 

 consists of five or six, are connected at the apex, and 

 all along the margins are many minute tubular spin- 

 nerets of a similar character. Immediately anterior to 

 the dorsal pores is a very long, slender, club-shaped 

 gland, which is connected with the extreme margin. 

 Vaginal and anal openings practically opposite. 

 Margin of pygidium (PI. XI, fig. 6) with three pairs of 

 rudimentary lobes ; the median pair are usually entire 

 and widely rounded ; the second and third, nearly as 

 broad again as the first, are either emarginate or irre- 

 gularly notched on the hind margin. In some exam- 

 ples there is also a fourth lobe, much longer than the 

 others, which has a bluntly serrate hind margin, but is 

 so very narrow as to be scarcely distinguishable from 

 the true margin of the pygidium. The plates are rudi- 

 mentary, spine-like, and arranged in pairs between the 

 lobes, at the base of which there is usually a marginal 

 pore. Within the body are four pairs of comparatively 

 short club-shaped glands connected with the spaces be- 

 tween the lobes, the second pair being much the longest. 



Puparium of the male (PL III, fig. 4) elongate. 

 Colour pale purplish brown ; margin paler ; with a 

 somewhat ochreous, mealy surface. Exuvias towards 

 the cephalic margin shining black. Secretionary cover- 

 ing pale greyish or white. 



Long. '75 1 mm. 



Perfect male unknown.
