2 ROBERT NEWSTEAD. 



hairy ; digitules long and slightly dilated, uppe: pairs wanting ; claws slender, with 

 a distinct ventral tooth near the tip. Eyes prominent and somewhat hemispherical. 

 Length, 0*9-1 mm. 



British Guiana : Issororo, N.W. District ; " inhabiting indentations in the bark 

 of a rubber-producing tree (Sapium jenmani) ; attended by ants which construct 

 coverings over the Coccids," 3.vi.l5 (A. A. Abraham, per G. E. Bodkin). 



Differs from L. primitiva (Towns.) in its larger size, the number of antennal seg- 

 ments, and the absence of spines on the legs. 



Llaveia primitiva var. pimentae, nov. 



Female, old adult. Dried example (1 only) elongate-ovate, highly convex dorsally, 

 hollow ventrally, the latter character almost as marked as in certain species of the 

 genus Lecanium ; segmentation of the abdominal region fairly distinct above ; the 

 cephalo-thoracic region with a faint median keel, not extending to the front margin. 

 The whole of the body clothed with a dusky white, farinaceous secretion, which is 

 denser in the hollows of the abdominal segments, the irregular depressions of the 

 thoracic area, and the hollow ventral surface ; the last-named also containing a 

 small quantity of pure white flocculent matter, in which were found two dead larvae. 

 Antennae of nine segments ; formula : 9, 1 (or 1, 9), 3, 2 (or 2, 3) (4, 5) (6, 7, 8). all 

 the segments longer than wide ; length twice that of the anterior femur plus tro- 

 chanter, or slightly more. Legs (anterior pair) relatively short ; femora incrassate. 

 equal in length to the upper portion of the tibiae, the latter nearly one and a half 

 times the length of the tarsi and furnished ventrally with nine to ten long slender 

 bristles ; claws smooth on the under surface. Integument dorso-ventrally rather 

 densely clothed with long stout bristles, and almost as thickly beset with circular 

 " rosette " pores ; marginal hairs much longer and denser than those seen elsewhere, 

 more especially so are they on the abdominal segments. Venter, near the distal 

 extremity, with three large oval rings. Length (after maceration in KOH), 5*5 mm. 



Female, young adult. Similar to the preceding, but with the marginal hairs very 

 long, the longest of them equalling the length of the antennae. The only example 

 has the antennae asymmetrical : one of ten segments with a partial division of the 

 4th, the other of seven segments only. 



Female, second stage. Shape similar to that of the old adult, but less than half 

 the size. Dorsum with or without a median ridge ; completely covered with a 

 dense, pale yellowish-white secretion ; segmentation faintly indicated. Antennae 

 variable, and in two examples asymmetrical, of eight or nine segments. Integument 

 much more densely hairy than in the adult ; marginal hairs as in the young adult 

 female. Length, 2*8-3*2 mm. 



Larva (fully developed). Short ovate. Marginal hairs long and continuous in 

 front ; the longest of those on the cephalic margin longer than the antennae. Caudal 

 hairs in four pairs, of which the median pair is the shortest and less robust than the 

 others, the longest hairs three-fourths the length of the body. Antennae with seven 

 long hairs, the longest of which is nearly equal in length to the antennae. In the 

 embryo larvae, taken from the body of the parent, the integument appears more
