Lecanium hesperidum L. Plate XVI, Pigs, i, 2, 3. 
Habitat. In conservatories on ///t/rA'/tv/ sp. and CV////.r sp. In 
green house on CHrus sp., Hedera helix and Ncrium oleander. 
This species was found on trunk, branches, leaves and fruit of 
the citrus trees. The scales upon the trunk are darker and more 
convex than those on branches. Those on branches and leaves 
incline to be yellowish, while those on the trunk are grayish. The 
outlines of both remain the same (Plate XVI, Fig i) except when 
modified by mid rib or by bordering on branch. 
The scales on ivy and oleander are uniforinlj' darker than orange 
scales; some of them are amber colored. The marginal outline is 
ovate, cephalic half being the wider. These scales are also more 
convex than the orange scales, and show on dorsum in some cases 
the figure H, the transverse bars joining the marginal spikes. 
Antennse, legs and nymphs of all these scales agree in structure. 
The subject of tesselation naturally arises in this connection. 
Considerable attention has been paid to the bleached derm. The 
results obtained, however, have not been constant. With the aid of. 
favorable reagents and suitable stains it is hoped that some 
definite data may be secured which will admit of something being 
said upon this point at a later date.
