940 THE AMERICAN. NATURALIST. [VoL. XXXV. 
ZOOLOGY. 
Coccide Americana. — The work bearing this title consists of a 
series of specimens neatly arranged in a portfolio, with sufficient 
printed matter to explain where descriptions of them will be found, 
and what plants they infest. The part just issued by Messrs. Quaint- 
ance and Scott of Georgia is the second of the series, the first having 
been prepared in Florida by Messrs. Rolfs and Quaintance. Each 
part contains twenty species, most of them of economic importance, 
and all correctly named; so it will readily appear that the work is a 
very useful one for experiment-station workers and others who have 
to determine Coccide. 
The only adverse criticism one can pass upon the part under review 
is that the synonymy given for the species is in many cases wrong ; 
in several instances the alleged synonyms are not even congeneric. 
This results from the uncritical acceptance of the work of other 
authors, and the present writer has erred too often in a similar way 
to be very severe on the subject. TPA € 
Coccide Stanfordiane. 
It is a pleasure to receive from Stan- 
ford University four excellent papers on Coccida, written by the | 
students of that institution. These papers are bound together as 
a contribution from the Hopkins Seaside Laboratory, and are as 
follows: (1) “Notes on Cerococcus,” by Rose W. Patterson; 
(2) “ New and Little-Known California Coccidze," by S. I. Kuwana; 
(3) “The Redwood Mealy-Bug;" by George A. Coleman ; (4) “ The 
San José Scale in Japan," by S. I. Kuwana. These papers are full 
of valuable information, and are accompanied by admirable plates. 
Miss Patterson describes and figures the three species of Cerococcus 
which occur on the Pacific slope (C. guercus Comst., C. ehrhorni 
Ckll., and C. corticis Twns. and Ckll. ), giving many new facts. She 
is evida unaware that a fourth species (C. ficoides Green) occurs 
in India. Mr. Kuwana gives for the first time an account of the 
transformations of Pseudolecanium tokionis, including the description 
of the adult male, which will be greatly appreciated by coccidolo- 
gists. He also describes three new species in the genera Eriococcus, 
Ripersia, and Lecanium. The Ripersia festucæ is a peculiar creature, 
having the female elongated, much like the male larva of ordinary 
Ripersia. It might be referred to Pergandiella were the antenna 
8-jointed ; possibly the discovery of the male will indicate its closer 
affinity with Fonscolombia.
