PSYCHE. 



71 



]nirplc-black, with imicli llie color and f-iir- 

 face of a prune ; abdomen segmented, ceplialic 

 end truncate, subeniarginate ; boiled in liquor 

 potassae, it turns the liquid a beautiful deep 

 reddish-purple, or plum color. Skin hyaline 

 after boiling, with very numerous round 

 glands of two sizes; antennae conical, rudi- 

 mentary, obscurely 4-jointed, about 54 |i 

 long; no legs; spiracles njoderate; anal tube 

 about iSo y. long, and 105 (i broad, at its 

 mouth very thickly beset witli round glands, 

 and having short, stout spines at its sides; 

 anal ring with six long, stout bristles ex- 

 tending the whole length of the anal tube. 



Hub. — Japan, on bamboo, at sheathing 

 bases of leaves. Very close indeed lo A. />iir- 

 ■piirea Signoret, but larger; I am not sure it 

 is more than a subspecies of f>urpurea, which, 

 however, lives at the other end of the palae- 

 arctic region. 



2. Pseiidolecaiiiiim tokioiiis (Ckll.). — Ja- 

 pan, on bamboo. Females, 6 mm. long, are 

 yellowish white, which appears to be the 

 color of the insect until the latest stage. 

 Mr. S. I. Kuwana has recently found this 

 species on bamboo at Stanford University, 

 California. 



3. Asierolecanium variolosuin{'R:iiz.) var. 

 jafonictim, n. var. — ?. Scale only about 



I mm. diam., greenish or jiallid ; fringe very 

 short, pinkish ; 9 pinkish when alive, turn- 

 ing orange in liquor potassae ; margin with 

 two rows of glaiids, one minute, simple, the 

 other figure-of-S, thirteen figure-of-8 glands 

 in isoji; scattered tubular glands. 



Hub. — Japan, on £>jiercus glanditlifera 

 Blume, inhabiting the bark of the twigs, with 

 Aspidiolus cryploxanthiis. Perhaps a distinct 

 species, but the tangible differential charac- 

 ters are few, as usual in the genus. 



4. Leca7iiuni cerasorum, n. sp. — $ . Glo- 

 bose, very convex, 5I mm. long and wide, 

 about 4 mm. high, shiny, pale ochreous, 

 soft, with scattered pits, having much the 

 color and texture of a ripe berry of Melia 

 azedarac/i ; anal region suffused with reddish 

 brown ; a good deal of white cottony secretion 



inside (beneath ) the scale, not visiiile on the 

 outside. Skin with tubular glands; anal 

 plates ordinary ; area around anal plates for 

 quite a distance strongly tessellate in Sais- 

 .se//rt-fashion ; marginal spines small and 

 simple; anal ring with about seven stout 

 bristles, about 210 |i long; mouth-parts small, 

 transverse diameter about 210 n; legs and 

 antennae small; coxa about 75 |i long, femur 

 stout, with trochanter about 140 |x, tibia 

 about 90 )i, tarsus about 75 )i, claw large; an- 

 tennae 6-jointed, 3 very long (about 90 |i), 

 the others all about 30(1, except 5, which is 

 about 24 p.. 



Hab. — Japan, on bark of twig of cherry 

 tree. In color and shape it I'esembles /,. glob- 

 iilosum Maskell, but differs at once by the 

 strong tessellation of the anal area. 



5. Aspidiotn.^ (Diaspidioliis) cryptoxanthtis, 

 n. sp. — ? . Scale on bark of twigs, almost 

 invisible, its color being that of the bark, 

 about i\ mm. diameter, circular to suboval, 

 often massed, very slightly convex, with 

 covered deep orange red exuviae, very con- 

 spicuous when exposed by rubbing; young 

 scales with a dot and ring; scales removed 

 from the bark leave a \vhitish patch. $ 

 bright orange when alive ; five groups of cir- 

 cumgenital glands, median of 4 to 5, anterior 

 laterals of 10, posterior laterals of 7 to S; two 

 pairs of lobes; median lobes contiguous in 

 the middle line, large, produced, broadly 

 rounded at ends, with the long outer slope 

 crenulate; second lobes similarly formed but 

 much smaller, separated by an appreciable 

 interval from the first; third lobes repre- 

 sented by a small nodule; squames short and 

 pointed, dagger like, inconspicuous, the best 

 developed are a pair at the second interlobu- 

 lar incision; spines quite large; interlobular 

 incisions with chitinous thickenings, the 

 inner one of the first incision nearly straight 

 but greatly swollen ; anal orifice small and 

 round, very near to hind end. 



Hab. — On bark of twigs of J^nercus glan- 

 dulifcra, in Japan. Differs from the Euro- 

 pean A. zonatus by the longer median lobes,
