Lachnosterna Hope, 1837, The coleopterist’s manual, vol. 1, p. 100. Type: Melo- 
lontha fervida Fabricius, by original designation. Present status: Accepted 
as a synonym of Phyllophaga. 
Phytalus EricHson, 1847 (not 1848), Naturgeschichte der Insekten Deutschlands, 
vol. 8, pt. 1, p. 658. Type: Melolontha pubereus Mannerheim, by present 
designation. Present status: Accepted as a valid subgenus of Phyllophaga. 
(Hrichson described the genus but included no species in it. Blanchard 
in 1850 redescribed the genus and included eight species, the first of which, 
pubereus Mannerheim, is here selected as the genotype.) 
Trichesthes ERICHSON, 1847 (not 1848), ibid., p. 658. Type: Melolontha pilosi- 
collis Knoch, monobasic (this is a synonym of Melolontha tristis Fabricius, 
which is therefore the type). Present status: Accepted as a synonym of 
Phyllophaga. 
Listrochelus BLANCHARD, 1850, Catalogue de la collection entomologique du 
Muséum d’Histoire Naturelle de Paris, Coleoptera, p. 141. Type: Listro- 
chelus laportei Blanchard, monobasic. Present status: Accepted as a valid 
subgenus of Phyllophaga. 
Chlaenobia BtancuHarp, 1850, ibid., p. 116. Type: Chlaenobia ciliatipes 
Blanchard, monobasic. Present status: Accepted as a valid subgenus of 
Phyllophaga. 
T'richestes BLANCHARD, 1850, ibid., p. 141 (unnecessary emendation of Trich- 
esthes Erichson). Type: Melolontha pilosicollis Knoch, monobasic (this 
is a synonym of Melolontha tristis Fabricius). Present status: Accepted 
as a synonym of Phyllophaga. (Blanchard says “absque character.” of 
Erichson’s description, though he credits it to Erichson. This is incorrect 
since Hrichson gives a short description; and Erichson’s spelling is. to be 
accepted. ) 
Tostegoptera BLANCHARD, 1850, ibid., p. 149. Type: Melolontha lanceolata Say, 
monobasic. Present status: Accepted as a valid subgenus of Phyllophaga. 
Eugastra LeConte, 1856, Journ. Acad. Nat. Sci. Philadelphia, ser. 2, vol. 3, 
p. 234. Type: Tostegoptera cribrosa LeConte, by present designation 
(Bloeker in 1937, Bull. Southern California Acad. Sci., p. 83, says that

is not the case). Present status: Accepted as a valid subgenus of Phyllo- 
phaga. 
Endrosa LECONTE, 1856, ibid., p. 234. Type: Melolontha quercus Knoch, by 
present designation. Present status: Accepted as a synonym of Phyllophaga.

MISCELLANEOUS NOTES ON SOME EXOTIC 
MELOLONTHINAE 
MELOLONTHA MELOLONTHA Linnaeus 
The peculiar elongated pygidial process will immediately separate 
both sexes of this European species from any of the described Melo- 
lonthinae of the New World, as also will the blunt mesosternal process 
prolonged between the middle coxae. Though close to Polyphylla in
