■white rod projects at liincl end. The insect itself (dried 

 specimens) is about 225 fx long and 150 broad (doubtless 

 much longer in life) ; segmentation of abdomen strongly 

 marked ; a long white rod projecting from anal tube (as in 

 Antonina and Ourococcus) ; the three last abdominal segments 

 have on each side a very long (about 300 /i) bristle, after the 

 manner of Icer7/a larva? ; legs and antenna? very dark ferru- 

 ginous ; antenna? G-jointed, with an extremely short third joint 

 (twice as broad as long) and a very large and long club, the 

 basal part of which is slightly constricted, so as to simulate 

 an additional joint. Joints 2 to 4 are cylindrical, 5 is cup- 

 shaped. Measurements in fi :— (1) 36, (2) 45, (3) 18, (4) 39, 

 (5) 24, (6) 105. 



Third stage. — Oval, about 1000 yu, long; turns crimson on 

 boiling in KHO. Antenna? reddish, very short and stout, 

 of 5 or 6 obscure joints, with many short bristles at the tip. 

 They are about 135 /x long and 60 broad, and very close 

 together, only about 45 yu, apart. Legs very short and stout. 

 Round dermal glands very numerous and exactly as in 

 Sphcerococcus. The anal region is provided with a tube and 

 is quite after the manner of Sphcerococcus c isuarince. 



1 had been quite uncertain as to the relationships of Crypto- 

 'kermes in the absence of the early stages. It is now clear 

 that the genus is closely related to the Australian Sphcero- 

 coccus and Ourococcus. 



Chrysomp)hulus (Melanasjn's) tonilensis^ sp. n. 



$ . — Scales on branches, about 2 millim. diara., oval to 

 circular, strongly convex, rough, with concentric ridges, dark 

 purplish brown to black ; exuvia? large, shining black, sub- 

 lateral, covered with an easily deciduous white film. Nearly 

 spherical, about 1400 fx long, caudal end rather strongly 

 chitinized. No circumgenital glands ; dorsal glands rather 

 numerous, minute, not over 3 yu, diameter ; anal orifice oval, 

 about 21 /i long and 108 from hind end; genital orifice 

 about 42 /x anterior to anal orifice; spines short, not over 

 12 /A long ; no squames ; three pairs of lobes, all low and 

 broad, the second and third with a central depression or 

 notch ; a low prominence takes the place of the fourth lobe ; 

 club-shaped glands in pairs, those of each pair alike, all short, 

 the longest only 18-21 yu. long.

The male scales also occurred in some numbers and are 

 oblong, reddish brown, often conspicuously white posteriorly ;
