Rostral filaments very short. Legs well developed and the tibio-tarsal articulations 

 very clearly defined ; coxae with three very long, distal hairs. Dorsal pores very 

 small, somewhat circular and very widely separated. Stigmatic spines (fig. 12, 6) 

 three, the central one very long, broad and curved ; the laterals somewhat bulbous 

 at the base, attenuated and finely pointed ; clefts shallow. Marginal spines (fig. 12, c) 

 very long, being equal in length to the 4th segment of the antennae ; they are dilated 

 and frayed or divided at the tips. Anal lobes (fig. 12, d) with the base and outer 

 edge about equal in length ; inner margin longest ; a very large spine attachment 

 on the dorsal surface, well within the distal angle ; ventrally (fig. 12, d) there is a 

 narrowly elongated patch of chitin which presents a finely reticulated pattern ; 

 spines and sclerite as shown in the illustration ; the relative position of these may, 

 however, vary according to the pressure of the covering glass. Anal cleft four times 

 as long as the anal lobes. 



Length, 4-2 mm. ; width, 2-2 mm.

The description of the old adult female is based upon a single example. One 

 young adult and several second stage females were also collected by Dr. Lamborn, 

 but all of these had been attacked by Chalcidids. 



This insect belongs to the L. longulum group, but seems to be quite distinct and 

 hitherto undescribed. 



Lecanium hesperidum (Linn,) (Plate vi, figs. 1-6). 



The colony from which I secured examples of the male puparia of this species, 

 described by me* in the year 1902, was subsequently kept under observation until 

 November 1904, when I was fortunate in securing perfect males — the first authentic 

 examples obtained in any coimtry, so far as I can trace, since Bouche's discovery 

 in or about the year 1867. As his description, quoted by both Boisduvalf and 

 SignoretJ imder the synonym L. lauri, Boisd., is of the vaguest possible kind, I give 

 the following details and append figures of this cosmopolitan pest which I trust 

 may prove of interest. 



Male (PI. vi, fig. 1.). Wings ample and faintly iridescent ; costal nervure bright 

 rose-pink. Body dull crimson or bright pale castaneous ; thoracic plates and . 

 apodeme slightly darker. Legs and antennae paler than the body ; hairs glistening 

 white ; eyes and ocelli black. Antennae (PI. vi, fig. 2) very hairy, of ten segments ; 

 4th and 7th longest ; apical segment with five long and faintly clubbed hairs. 

 Upper surface of head and genae hairy. Legs hairy ; digitules normal. Abdomen 

 hairy ventrally ; anal segment (PI. vi, fig. 3, 3 a) with a pair of long w^hite filaments, a 

 pair of relatively long slender hairy tubercles and also a pair of large protruding 

 gland-fike processes. Each of the white filaments is supported by a pair of bristles 

 one long the other relatively short. Stylus (PI. vi, fig. 3) somewhat bluntly 

 pointed. 



Length, 1'75 mm. 



Male puparium (PI. vi, fig. 4). This has already been described {I.e.).
