AFRICAN SCALE INSECTS (COCCIDyE).

Female, old adult. — These were so completely enveloped by the hyphns of a 

 fungus as to render nearly all the structural details invisible. It was possible to 

 ascertain, however, that the antennae ai"e similar to, or almost identical with, those 

 in the young adult ; the large dorsal pores are also present, though it is impossible 

 to say if they are arranged in the same way ; the marginal spines are identical ; 

 but the digitules of the anterior tarsi (fig. 12, a) are more distinctly dilated, and 

 those of the claw are slightly less spathuliform. 



Fig. 12. — Ceroplastodes (jowdcyi., Newst. ; a, young adult female ; 6, tarsus of old adult female ; 



c, antenna ; d, tarsus ; e, derm ; /, one of the paired circular glands, ventral aspect ; g, the 



same in profile ; h, stigmatic cleft. 



Female, young adult (fig. 12, h). — Ovoid. Anal cleft well defined ; lobes longer 

 than broad ; setiferous ring with ten hairs. Antennaj (fig. 12, c) of eight 

 segments ; the sixth and seventh each with a single slender spine, the eighth with 

 4-5 ; there is a very long hair arising from near the base of the third and 

 another from near the apex of the fifth. Legs well developed ; ungues (fig. 12, d) 

 very short and suddenly pointed ; digitules broadly spathuliform ; tarsal digitules 

 very long and stout, but the apex is only slightly dilated. Stigmatic clefts 

 (fig. 12, A) very deep and narrow ; the two lateral spines long, stout and bluntly 

 pointed ; marginal spines short, simple. Derm (fig. 12, e) with small ovate pores, 

 widely separated and faintly indicated. There are four pairs of circular glands 

 (fig. 12,/, g), the first placed near the anterior margin ; the second near the base 

 of the antennae ; the third near the insertion of the second pair of legs ; the 

 fourth near the posterior margin, one on either side of the anal cleft.
