Selys, all then alive and all older than himself, he laughingly 

 said, "I am the baby at seventy-four." I may, perhaps, be 

 permitted to add one other personality. In February, 1890, he 

 sent me his unpublished notes on Leucorhinia, giving me per- 

 mission to publish them, and when I wrote him for a title, he 

 wrote "Synopsis of Leucorhinia" with my name as author, al- 

 though the work was all his own. None but a generous man 

 would have done so. 



Dr. Hagen belonged to an age that has passed away — when 

 it was still possible to be an entomologist, as the four hundred 

 and odd titles marking his fifty years of publication on all the 

 orders sufficiently attest. His " Bibliotheca" and the entomolog- 

 ical collections at Cambridge are the monuments of his life's work. 



At the time of his death, Dr. Hagen was the senior by election 

 of the ten Honorary Fellows of the Entomological Society of 

 London, having been elected to that body in 1863, one of the 

 twelve honorary members of the Entomological Society of Bel- 

 gium, and correspondent, or member of the American Entomo- 

 logical Society, Entomological Society of Stettin, Boston Society 

 of Natural History and other scientific bodies. — P. P. C.

Note on the Genus Pseudococcus WestWood. 



By T. D. A. Cockerell. 



According to Scudder (Nom. Zool., p. 266) the x\.dsa.&Pse2ido- 

 ^occus dates from 1848, but I find what appears to be its earliest 

 publication in the "Modern Classification of Insects," vol. i 

 (1839), p. 118. Here Westwood writes: 



" Pseudococcus W estw . (C. adonidum, cacti, etc.), having the 

 female not fixed, and clothed with a woolly secretion." 



Of the two species mentioned, adonidum belongs to what we 

 now call Dactylopius and cacti to Coccus sens. Signoret. The 

 definition would fit several genera as now understood, but in the 

 absence of any indication of a type species we should take 

 adonidum as the type, as it is first mentioned. 



However, in Mod. Class. Ins. vol. ii (1840), p. 448, all doubt 

 on this score is removed, since we read that C. ilicis is to be con- 

 sidered the type of Cocciis; and of C. cacti, the author states: 

 ■"this insect . . . belongs to a genus . . . which I propose to
