Antennae of L. aniiniiacum'^ on prune, from Healdsburg, Cali- 

 fornia (Ehrhorn). 



Lecanium hesperidum L. Plate XVI, Figs, i, 2, 3. 



Habitat. In conservatories on Abiitilon sp. and Citrus sp. In 

 green house on Citrus sp., Hedcra Iiclix and Nrriitui 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 uniformly 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. 



Antennae, 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 

 resultsobtained. 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.

These scales differ in number and relative sizes of segments of 

 antennae as compared with Comstock"s description in U. S. Ag. 

 Rep., 1880, p. 336.
