OBSERVATIONS OX SCALE-INSECTS (COCCIDAE) — III. 375 



Male, second instar. Elongate, markedly attenuated posteriorly. Pygidium 

 narrowed distally ; lobes and tubular squamae as in the adult female. 



Male, third instar. Completely enclosed within the pellicle of the second instar, 

 and filling it with the exception of the pygidial area. Short, stumpy antennal and 

 leg-sheaths present. Anal segment of abdomen lobed, each lobe with a pair of stiff 

 stout hairs, one of which is as long again as the other ; the two succeeding segments 

 have also a pair of short stiff hans. 



Male. Winged. Legs strongly spinose. Two pairs of large ocelli. 



Larva. Short ovate. Antennae of six segments ; terminal segment as long as 

 the three preceding ones, with a long slender lateral spine ; formula : 6, 1 (2, 3, 4, 5). 

 Between the antennae, dorsally, are two pairs of very long hairs, the longest pair 

 tivo-thirds the length of the body ; behind these are four much shorter hairs ; marginal 

 hairs in pairs, one about one-third the width of the body, the other much shorter. 

 Pygidium (fig. 24, d) with two pairs of lobes and a pair of long setae. 



Maueitius : Botanic Gardens, on palm trees, 1915 {de Charmoy). 



Chiefly on the upper surface of the leaves, in association with Asterolecanium 

 spectubile, sp. nov., but the latter almost exclusively on the uiider surface of the leaf. 



Green* has described a Coccid under the name Aspidiotus {Chrysomfhalus) cistu- 

 loides, the female puparium of which is very like that of mauritianus in having the anal 

 portion highly tilted. But the female of the latter species is entirely different and 

 approaches very closely Furcaspis riifa, Lindinger,f in the structural characters of the 

 fringe of the pygidium, both species possessing the singular truncated tubular squamae. 

 F. rufa however possesses three of these structures between the second and third 

 pairs of lobes, and also two additional pairs of long spinose hairs just beyond them. 

 Moreover Lindinger makes no reference to the singular tilting upwards of the puparium 

 in his species. I take it, therefore, that this marked characteristic was entirely 

 wanting in his specimens. The larval characters of A. tnauritianus differ from those 

 of F. rufa only in the minute details of the pygidium. 



Aspidiotus pimentae, sp. nov. (Plate vii). 



Female puparium. Central pellicle resting in a well-defined circular pit or depres- 

 sion in the bark of the food-plant. Form subcircular, slightly produced posteriorlv 

 and uptilted by the thick ventral pellicle, which does not extend to the margin behind. 

 Dorsal pellicle strongly convex or subconical ; larval pellicle subcentral (in young 

 forms it is central), more or less nipple-like, generally nude and bright castaueous or 

 piceous ; secretionary portion covered with the grey epidermal layer of the bark ; 

 beneath this the pellicle is thick and varies from dark castaneous to dark piceous. 

 Yentral pellicle low convex externally, fitting closely into the pit or depression ; 

 central area with a thin, circular, whitish pellicle, the diameter of which is approxi- 

 mately equal to the width of the very dense dark border surrounding it. Greatest 

 diameter averaging 1*5 mm. 



Female, adult (fig. 25, a). Without thoracic constriction. Three or four of the 

 abdominal segments well marked and slightly tuberculate at the margin. Rudi- 

 mentary antennae with two long spines of equal length. Anterior parastigmatic glands
