J. W. SCOTT MACFTE — ON A NEW AFRICAN SPECIES OF COCCIDAE. 33 



Larva (taken from the ovisac of the female) — elliptical. Antennae (fig. 3 A) 

 six-jointed, the third joint being the longest ; two especially long hairs on the 

 third and sixth joints. Stigmatic area (fig. 3 B) marked by one long and two 

 short spines, which are slightly spatulate at their tips, and a row of three or 

 four daisy-shaped spinnerets (fig. 3 B a) leading inwards towards the stigma. 

 Margin with a series of small pointed spines. Legs well developed. Caudal 

 setae (fig. 3 C a) very long, in some cases measuring as much as two-thirds of 

 the length of the body ; at the base of each seta a group of four spines. 

 Ano-genital ring (fig. 3 C) with six stout hairs.

Larva. — (A) antenna ; (B) stigmal spines ; (B«) spinnerets ; (C) anal segment ; 



(C a) caudal setae. 



Male. — Puparium (fig. 2 G) glassy opaque white, elongated, with parallel 

 sides ; form not differing materially from that of the genus Lecanium ; margin 

 with an imperfect and irregular fringe of waxy appendages. Length 2'5 mm., 

 breadth To mm. 



Adult male unknown.

Food-plant. — " Pride of Barbados" (Cacsalpinia puleherrima, Sw.), a prickly 

 shrub growing to a height of 5 to 10 ft., which, on account of its showy red or 

 yellow flowers, is a favourite in the gardens and compounds of Nigeria. 



In the form of the ovisac of the female this species bears a striking resem- 

 blance to Ceronema koebeli, Green {I.e.), but morphologically the latter is very 

 clearly distinct. The distinctive characters in C. africana are that the antennae 

 are decidedly stouter, the digitules of the claw are less dilated, the central 

 stigmal spine is considerably longer, and there is a total absence of short spines 

 leading up to the stigmata. Furthermore the derm cells are oval in shape and 

 not " irregularly polygonal " as in C. koebeli,
