mesothorax) slightly over twice as long as the second, the latter almost 

 twice as long as the first abdominal segment and subeqiial to the second ; 

 about two-thirds as long as the third, the fourth segment deeply 

 emarginate in the middle, at which point it is slightly shorter than the 

 first abdominal segment ; greatest vertical diameter of abdomen scarcely 

 more than that of the thorax, venter convex (and without the blackish 

 protuberance shown in Dr. Meinert's figure 2); head sparsely clothed with 

 a short yellowish-white pubescence, a row of black postocular bristles 

 extends from upper end of each eye to the oral margin, apices of palpi 

 beset with a dense cluster of black bristles ; legs beset with short, black,

Collected July 5, 1901, at Flagstaff, Arizona, by Mr. H. S. Barber, 

 at whose request the species is dedicated to Mr. E. A. Schwarz, whose 

 careful investigations have brought to light so many rare and interesting 

 forms in all orders of insects. Type No. 6703, U. S. National Museum. 



NOTES ON THE COCCIDtE. 



BV MRS. C. H. FERNALD, AMHERST, MASS. 



In an article on the genus Lecanium, published in the Canadian 

 Entomologist, Vol. 34, p. 177 (1902), I stated that I inferred that Costa 

 proposed generic names for the Coccid?e in his Prospetto di una nuova 

 descrizione metodica del genera Coccus L., a work I had not seen at that 

 time, as no copy could be found in the libraries of this country or in 

 London. Mr. Fernald has, however, recently secured a copy of this 

 exceedingly rare work, published in 1828, from Naples, Italy. 



Costa in his Prospetto published in 1828 proposed and described 

 three genera. These were Ca/ym//iata, Diaspis and Diaprosteci. As 

 this last is only a vernacular name, it need not be considered, although 

 the author gave Coccus adonidum, L., as an illustration. Calymmata was 

 divided into Monaspidae and Polyaspidae. Under this genus the author 

 mentioned several species as illustrations. The genus Diaspis was 

 described, but as no species were mentioned or referred to, it is without a 

 type so far as the Prospetto is concerned. There is therefore nothing in 

 this work to affect the classification of the Coccidse. 



In his Nuove Osservazioni intorno alle Cocciniglie, published in 

 1835, Costa used Calypticu% hesperiduin in some places and Calyminatus 

 hesperidum in others, while he used Dactylopius instead of Diaprosteci 

 of the Pros{)etto. In the Fauna del Regno di Napoli, he divided the 

 Coccidfe into three genera, Calyptictis, Dactylopius and Diaspis, each of 

 which was described and with well-known and fairly well described 

 species under them.
