178 PSEUDOCOCCUS ACEEIS. 



Anal orifice (fig. 4) placed well within the margin. 

 Dermis thickly set with rather long hairs and numerous 

 simple spinnerets. 



Long, 2-4*25 mm. 



Ovisac of the female (PL C, fig. 1, Vol. I) very 

 elongated, sides parallel, rarely straight, but often 

 curved or contorted; white and closely felted at first, 

 but speedily becoming brittle and ruptured ; interior 

 sometimes faintly yellowish. Where the insects are 

 numerous on the limited surface of the gorse, the 

 ovisacs are often massed together on the main branches, 

 but I have never found this to be the case on other 

 food-plants. 



Male (fig. 6) smoky-brown or rich madder-brown and 

 mealy; legs and antennas paler; inner caudal filaments 

 long, outer pair about half the length of the former. 

 Wings rather large, nervure at base yellowish. Antennas 

 (fig. 7) of ten joints, thickly set with rather long hairs; 

 the longest hairs on the last four joints very faintly 

 knobbed, so faintly that the character is very difficult to 

 trace. Legs hairy ; digitules to claw apparently very 

 short and not extending to tip of claw ; those of the 

 tarsi represented by simple short hairs. 



Genital armature (figs. 8, 8 a) broad, and suddenly 

 pointed ; inner (?) penis-sheath very broad, with the ex- 

 tremity pointed and very slightly recurved. On either 

 side of the genital armature are three long hairs, each 

 successively longer than the other, besides several 

 shorter hairs, all of which are surrounded by a group 

 of simple spinnerets; the second caudal group is 

 attached to the margin of the succeeding segment, and 

 consists of two long and one or more short hairs, and 

 it is also surrounded by spinnerets, as in the first 

 group. Margins of each of the abdominal segments 

 with a series of hairs, and there are two converging 

 rows of shorter hairs at the extremities on the dorsum 

 of the genitalia. 



Long, 23 mm. 



Larva bright lemon-yellow ; ovate ; rostral loop
