Has Hydrodromia any standing as a genus, considering 

 that its author liad never seen either of the possible types'? 



Opinion 1. — The Type of Heleodromia Haliday (1833) 

 was fixed as immaculata Haliday by Curtis (1834), and 

 by Maequart (1835); SCIODROMIA Haliday (1840), Type 

 immaculata Haliday (Haliday, 1840), is a synonym. 



Hydrodromia Maequart (1835) n.g. [= * Heleodromia 

 Haliday (1833) — Group B. sp. 2-3) ; = * Heleodromia Haliday 

 (1840)], The Type is either hipunctata Haliday, or stagnalis 

 Haliday, and for either of these Hydrodromia Maequart 

 is a potentially valid genonyui.

Question 2. — (J. H. Durrant.) 



Stephens [111. Br. Ent. Haust. 4. 119 (1834)] wrote thus of 

 Carpocapsa Tr. : — 



" This genus requires considerable revision ; the three first 

 species" [i.e. 1. pomonella L. ; 2. splendana Hb. ; 3. gros- 

 sana Hw.] " form the true Carpocapsae of Treitschke — Cydia 

 of Hiibner — the remainder are mostly included in the genus 

 Grapholitha of Treitschke, and constitute other genera of 

 Hiibner, as indicated hereafter." 



The only species common to Hiibner and Stephens, and 

 which was therefore regarded by Stephens as the Type of 

 Cydia Hb., is pomonella L. 



Are we to consider that Stephens states the case thus : — • 



Carpocapsa Tr. (1829) = Cydia Hb. (1826), Type pomo- 

 nella L., with which splendana Hb. and grossana Hw. are 

 alone congeneric ? 



[Curtis, Br. Ent. 8. expl. PI. 352 sp. 1-24 (1831), cited 

 pomonella L. as the Type of Carpocapsa Tr., and Walsing- 

 ham, Pr. Z. Soc. Lond. 1897. 130-1 no. 69 sp. 182 (1897), 

 adopted Stephens' restriction and cited pomonella L. as the 

 Type of Cydia Hb. also.]
