References

* Compare the young of L. Fitchii. The lately-batched young of species of Lecanium differ more or less in appearance. Thus, the living young of L. armneniacum, Craw, sent by Mr. Ehrhorn from Sta. Clara Co., California are pale gray mottled with white, with a conspicuons white or yellowish-white dorsal longitudinal band. Miss Tyrell considers armeniacum a variety of pruinosum, which probably is correct.

† It is also quite distinct from L. pruinosum, Cog., which Mr. Ehrhorn sends me on rose from Mountain View, California.

* In both cases the names of the exact localities were sent, but I regret that I am totally unable to decipher them. Will correspondents please write names of localities plainly?
