New genera and species : — 
H. W. Bates, Ann. N. H. (4) xii., characterizes — 
Mallamhyx, p. 152. Agrees with Australian Pachydissus in its un- 
armed antennae and thorax, and finely pubescent surface, but differs 
in facies and in the very slight nodosity of 3rd and 4th antennal joints. 
Central groove of head extends behind to neck. 31. jajjonicus^ ibid., 
Japan, and ? Pachydissus fulvidus, Pasc. 
Stenodryas, p. 153. Between the CalUdiopsides and Graciliides. Re- 
sembles Ceresium, except in the long slender legs and abruptly clubbed 
femora. S. clavigera, p. 154, Hiogo. 
Stenygrinum, p. 154. Facies of Stenygra, but closely allied to Ceresium, 
and more so to the Australian Bethelium, from which it differs in its 
cylindrical thorax and less hirsute antenna. S. quadrinotatum, ibid., 
Ipongi. 
The same author, op. cit. xi., characterizes — 
Phcenissa, sub-g. of Ommata : elytra entire or nearly so. Oregostoma 
nigripesj and (?) discoideum, Serv., Rhinotragus puniceus, Newm., and 0. 
(P.) bipartita, Parana, p. 26. 
Chrysaethe, sub-g. of Ommata : elytra scarcely abbreviated, apex trun- 
cated. 0. atrata, Bates, &c. p. 27. 
Rhopalessa, sub-g. of Ommata : elytra opaque. 0. (R.) clavicornis, 
New Friburg, p. 28, and Rhinotragus tenuis, Burm. 
EclijJta, sub-g. of Ommata, p. 29: legs slender, middle femora abruptly 
but not very broadly clavate, elytra with sides sub-parallel, apex trun- 
cated. Odontocera irene and eunomia, Newm., wgrota, Bates, Agaone 
rnonostigma, malthinoides, and ruficollis, Bates, Oregostoma fenestratum, 
Luc, and 0. (E.) castanea, p. 29, hrachialis and liturifera, p. 31, lanugi- 
nosa, p. 32, Rio Janeiro, thoracica and flavicollis, p. 30, prolixa, p. 32, 
crihripennis, p. 33, vitticollis, p. 34, aniguttata, xantho, and pcecila, p. 35, 
Parana, erythrodera, p. 33, New Friburg. 
Acorethra, p. 126. Closely allied to Charis and Phygopoda, differing 
from the former in its elongate hind legs and abdomen, and from the 
latter in its simple hind tibiae and obtuse cuneiform elytra. A. chry- 
saspis, ibid., New Friburg. 
Phespia, p. 127. Closely allied to Tomopterus: enlarged antennal 
joints forming a thick cylinder, elytra subuliform. Facies of Cerceris 
(Hymenoptera). Odontocera cercerina, Bates, Charis corinna, Pasc, and 
P. simulans, ibid., Rio Janeiro andParan^i. 
Apostropha. p. 130. Allied to Ommata, but differing in the widely 
separated eyes from all the typical Rhinotragides. A. curvipennis, ibid., 
Parana. 
Stenopseustes, p. 131. Facies of Ommata. S. wger, ibid., Parana. 
Xenocrasis, ibid. Unites characters of true Necydalides and Rhinotra- 
gides, being most nearly allied to the latter, though with distant and not 
enlarged eyes and laterally carinated forehead. X. badeni, p. 132, New 
Friburg. 
Leconte, Sm. misc. Coll. 264, characterizes — 
Gonocallus. p. 171. Male antennae 12-jointed; eyes more inclined to
