CATALOGUE OF RECENTLY DESCRIBED COCCID^. 
By J. G. Sanders, M. A., Assistant. 
Since the publication, in March, 1903, of Mrs. Fernald's Catalogue^ 
many new genera, species, and varieties of Coccidas from various 
regions haA^^e been described by enthusiastic entomologists. Nine 
genera, 6 subgenera, 137 species, and 22 varieties comprise the follow- 
ing catalogue, which is fairly complete to date. The majority of the 
references are to publications which have appeared since March, 1903; 
however, a few previous to this date are cited, which were overlooked 
by Mrs. Fernald in the stupendous task of preparing her most useful 
contribution to coccidology. 
The Bureau of Entomology maintains a complete bibliography, by 
the card-index system, of all publications pertaining to Coccidae, both 
economic and sj^stematic. At the suggestion of Prof. T. D. A. Cock- 
erell, and with his valuable assistance, the writer has prepared a sup- 
plementary catalogue of new species onl}^ which he hopes to publish 
annxially hereafter. In this work the writer respectfully begs the 
assistance of all authors by the sending of separates or notices of pub- 
lication, and specimens, if possible, to this Bureau, where they will be 
properly cared for and recorded. 
The large national collection of Coccidce, containing 1,038 identitied 
species, of which num})er 660 are tj^pes and cotypes — besides much 
unidentified material from Australia, India, China, and Japan — has 
been carefully arranged alphabetically in cases built especiall}^ for the 
purpose. Each specimen is carefully wrapped in lens paper and put 
into a small telescopic pasteboard box, 50 by 75 mm. and varying from 
10 to 50 mm. in depth, properly labeled on the edge. Five rows of 
these boxes, card-index style, fill the regulation insect drawer; and, 
with the drawers labeled, but a moment is necessary to find any speci- 
men desired. Localit}^ cards, giving all known data for each specimen, 
are also filed in alphabetical order. 
The writer once more begs the assistance of all workers on Coccidae 
in publishing annually a complete bibliography of all new species and 
in the maintenance of a complete bibliographical card index of all pub- 
lications relating to scale insects.
