78 THE ENTOMOLOGIST. 



another on the score of convenience is absolutely in defiance of 

 the 'rule of priority,'" but when the earlier name is found to 

 have been wrongly accepted up to the present, it is, I think, 

 obvious that such a substitution is not only convenient, but 

 obligatory. 



3. It may be noted, with reference to recent discussions, 

 that Sherborn (' Index Animalium,' 1902) accepts Geoffrey's 

 1762 genera.

1. Fernald Cat., p. 54. Lecaniodiaspis ; the original spelling 

 of this was Lecanodiaspis, and the type is sardoa, not dendrohii, 

 as stated. 



2. A species omitted in Fernald Cat. (apparently) is Coccus 

 pruni, Burmeister (May 28th, 1849), in Zeit. fiir Zoologie, p. 177, 

 on Primus domestica, Germany. 



The diagnosis is as follows : — 



" <? viridi-griseus, albo farinosus, alls albidis ; scutello parvo, 

 binodoso ; antennis pubescentibus, pedibus nudis gracilibus ; 

 abdominis segmento penultimo et antepenultimo bisetoso. Long. 



" ? elliptica, viridigrisea, albo farinosa, capite magno in 

 prothoracem postice producto ; abdominis lateribus paululam 

 depressis, segmentis duobus ultimis utrinque pilosis. Long. 

 1 lin." 



This is followed by a long description in German. 



3. The references to many of the Zehntneriau species are in- 

 correct, being taken from separately paged reprints. At the 

 present moment I can supply a correct reference only to the 

 following : — 



Aspidiotus sacchari caidis, Zehntner (July 15th, 1897), 'Archief 

 voor de Java-Suikerindustrie,' v. p. 735-44, pi. viii.

 In the 'Entomologist ' (August, 1903, p. 215), I stated that 

 I had not seen the description of Philia, Schiodte. I have now 

 been able to secure Kroyer's ' Naturhistorisk Tidskrift,' Bind iv. 

 (1842-3), and find that Philia is not a valid genus. In the 

 ' Eevisio critica specierum generis Tetyrae Fabricii, qvarum 

 exstant in Museo Regio Hafniensi exempla typica ' (pp. 279-312), 

 "Philia ??i." is simply placed at the head of the descriptions of 

 several species below the Fabrician nomenclature. On p. 281, 

 Schiodte states that Calliphara and Callidea (sic) are preoccupied 

 by Calliphora, Macquart, 1835, and Calleida, Dejean, Latr., 

 1829, and that they form only one genus. On pp. 315-60 are 

 the " Forhandingler i det skandinaviske entomologiske Selskab," 

 in which (on pp. 346-8) Schiodte discusses his own paper, and 

 definitely states that Philia is proposed as a new name for the 

 above mentioned genera. As neither Calliphara nor Calidea is
