APTEROCOCCUS FRAX1NL 211 



abdominal segments above, a few, on the terminal 

 segments, being longer and stouter than the others. 

 The uniarticulate mentum rather small and somewhat 

 pointed. 



Long, *50-*75 mm. 



Sac of the adult female (PI. C, fig. 2, Vol. I), when 

 isolated, more or less spherical, composed of white, 

 closely-felted, but somewhat brittle material, the 

 largest scarcely exceeding 1 mm. in diameter. A single 

 sac often contains two or more individuals; and as a 

 rule the sacs are packed closely together in irregular 

 masses quite filling the narrow crevices of the bark of 

 the tree. 



Second-stage female (PI. LXXII, fig. 1) pale red or 

 yellowish-red ; eyes piceous. Form short ovate ; seg- 

 ments well defined ; structural details resembling those 

 of the adult insect. The insect in its early stage is 

 partly covered with a thin cottony secretion. 



Male (PL LXXII, fig. 6) apterous. Bright orange- 

 red or orange-yellow, with the last six segments of the 

 abdomen greenish-yellow ; eyes black. Head a very 

 little narrower than the thoracic segment. Antennae of 

 seven (PI. LXXII, fig. 7) joints ; * first and second 

 joints broad ; the third gradually narrowed towards its 

 articulation with the second joint ; the fourth and fifth 

 joints are also narrowed at the base, but are much 

 shorter and less attenuated than the third ; sixth very 

 broad and long ; seventh longest, obtusely pointed and 

 strongly constricted towards the centre, and usually 

 bearing two long and two short hairs. Legs (PI. 

 LXXII, fig. 8) scarcely longer than the antennae, 

 resembling those of the female, but stouter. Genital 

 armature (PI. LXXII, figs. 9, 9 a) extremely short, 

 composed of three distinct parts (fig. 9, profile) ; the 

 dorsal portion is much the largest, and is shaped some- 

 what like a short blunt claw, Avhich is apparently 



* In my original diagnosis (1. c.) I gave the number of antennal joints as 

 eight, then mistaking the strong constriction on the terminal joint for a true 

 articulation.
