ACLERDA. 1 1 



tokionis is, as Mr. Green has recently discovered, also 

 an Aclerda, and was originally found on a species of 

 bamboo in the vicinity of Tokio, Japan. Whether the 

 remaining species in this division can here be placed 

 without materially widening the bounds as set forth 

 by Signoret, I must leave with those students in whose 

 hands the more recent material is placed. 



The puparium of the male of A. Berlesii is a felted 

 sac open at the posterior extremity. The perfect male 

 has a short genital armature, and there are no caudal 

 filaments. 



All the known larvae are remarkable for their exces- 

 sively elongate form. The margins of the body are 

 furnished with a regular series of short, blunt hairs or 

 spines. The six-jointed antennae and the legs are well 

 developed ; the anal lobes are placed at the extremity 

 of the body, as in Kermes ; and the anal ring or orifice 

 is simple.

 (PL XXXVI, figs. 1, 5-8 ; PI. XXXVII, figs. 2, 3.) 



Aclerda japonica, Newstead; Ent. Mo. Mag., s.s., 

 vol. xii, p. 84, figs. 6-9 (1901). 



Adult female (PI. XXXVI, fig. 5) covering all un- 

 protected portions of her body with closely-felted 

 white wax, and those portions, dorsal and ventral, in 

 contact with the food-plant with a thin white mealy 

 wax ; the secreted matter together with the food-plant 

 forming the ovisac, which must be considered more or 

 less incomplete. 



Form elongate, about three times longer than broad, 

 slightly widest towards the anal extremity. Antennae 

 (PL XXXVI, fig. 7c) rudimentary, in the form of 

 minute tubercles, bearing several slender hairs at the 

 apex and a slightly longer and stouter one near 

 the centre and also at the side. Legs absent. Ros-
