Chrysomelides, 
Stal has completed his monograph of the American Chryso- 
melides (Nova Acta Upsal. ser. 3. vol. v. pp. 177-365), the 
third part, published last year containing descriptions of 246 
species of Chrysomela, as here defined by Stal, 1 Gastrceidea, 
1 Stenomela, 1 Prasocuris, 4 of Microtlieca, 7 of Pyxis, 1 TVo- 
chalonota, 43 of Plagiodera (incl. Lina), 1 Limenta, 2 of Lio-* 
glacis, 7 of Gavirga, 11 of Phcsdon, and 1 Aulacoscelis (g. n.). 
This gives a total of 326 species in the present part, vrhich, 
added to those previously described by the author, brings the 
whole number of American Chrysomelides known to him to 655. 
In addition to these, 36 species described by various authors, 
but with which he is unacquainted, are cited, with the original 
descriptions, in the appendix. 
The follomng genera are regarded by Stal as more or less synonymous with 
sections of Chrysomela : — Leptinotarsa (Stfil), Myocoryna (Stal), Eugomjeha 
(Stal), Elytrospheera (Stc^l), Strichosa (Blanch.), Prosciccla (Erichs.), Eory- 
sterna (Guer.), Cryptostetha (Baly), Lahidomera (Chevr.), Deuterocampta 
(Erichs.), Stilodes (Baly), Calligrapha (Dej.), Doryphora (111.), Leucocera 
(StSl), Desmogramma (Erichs.), Cosmogramma (Erichs.), Zygogramma 
(Erichs.), Polyspila (Hope). 
Baly (Journ. of Ent. ii. p. 433) characterizes the group 3Iyo- 
chroinm and tabulates its constituent genera as follows (/. c.
