CATALOGUE OF RECENTLY DESCRIBED COCCID^. 



By J. G. Sandeks, 31. A., Assistant. 



Since the publication, in March, 11103, of Mrs. Fernald's Catalogue'' 

 many new genera, species, and varieties of (>occida3 from various 

 regions have 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 iViaintains a complete bibliograph}', by 

 the card-index system, of all pul)Iications pertaining to Coccidffi, both 

 economic and systematic. At the suggestion of Pj'of. T. D. A. Cock- 

 erell, and with his valual)le assistance, the writer has prepared a sup- 

 plementary catalogue of new species onl}^, which he hopes to publish 

 annualli/ 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 Coccida3, containing 1,038 identitied 

 species, of which number 660 are types and cotypes — besides much 

 unidentified material from Australia, India, China, and Japan — has 

 been carefully arranged alphabetically in cases built especiallj' 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 nun. in depth, properlj^ labeled on the edge. Five rows of 

 these boxes, card-index stjde, 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.
