Wax not thus surrounding branch i. 



i. Waxy scale small, adults less than 5 mm. long, light yellowish.. .scutigera. 



Waxy scale larger, over 5 mm. long 2. 



2. Wax light amber, two lines of white secretion down each side. . Mendozce. 



Wax creamy white, no line of white secretion down each 



side Bemardeusis. 



(b.) Microscopical Characters. 



Strongly chitinous, with well-defined patches of perforations .. Bruneri. 

 Less chitinous, without such patches 1. 



1. Small species, under 3 mm. long, with a large, very well defined chiti- 



nous caudal patch scutigera. 



Larger, with the chitinous raudal area gradually shading into the 

 surrounding areas 2. 



2. Antenna? 7-jointed, about : 90 \>. long Mendozce. 



Antennas 8-jointed, about 240 /i long Bernardensis. 



(5.) Ceroplastes Bruneri, n. sp. (T. D. A. & W. P. Ckll.). 



¥• Wax cream-colour, surrounding twigs, the whole mass 15 mm. 

 diam., the twig being 7 mm. ; dorsal nuclei shining white, sunken in 

 deep depressions ; close behind each is a small aperture through which 

 the caudal horn is seen ; the waxy mass is conspicuously flecked with 

 snow-white secretion. 



$ . Dark red-brown, dorsally almost black, basally lighter and red- 

 der; subpyriform, with a truncate base; alt. 5V3, long. 4, lat. 5 mm., 

 breadth of base 2^ mm., dorsum shiny; caudal horn short, placed at 

 top of posterior slope and directed upwards. The horn is placed higher 

 up than in C. cande/a. The insects are not separated by wax, but their 

 adjacent sides show much chalk-white secretion, in vertical bands. Skin 

 (dorsal and lateral surfaces) strongly chitinous throughout, orange-fer- 

 ruginous by transmitted light, anal region a rich dark chestnut ; large 

 oval areas (the largest about 240 /i long) full of perforations ; at and near 

 the margins the skin is strongly tuberculate, and perforate ; antennae and 

 legs ordinary. Legs measuring in /i : femur + trochanter, about 135; 

 tibia 105 (with a rather long hair 27 // from the end); tarsus 75 ; claw ^ 

 slender, nearly straight, with a slight denticle within near the base ; tarsal 

 digitules 45 \i long, rather stout. 



Hab. — San Bernardino, Paraguay, Sept. 23, 1897. Close to C. con-
