New genera and species : — 
Acalodegma, Thomson, 1. c. p. 261. Type of a new division, Acalo- 
degmites, to be placed near Lacordaire’s Micropsalites, but with the 
antennae of $ moniliform, longer than the body, the eyes rather approxi- 
mated, the mandibles oxsorted, palpi slender and short, and posterior 
femora much shorter than the apex of body in both sexes. Unites cha- 
racters of Polyarthron, Meroscelisus, Acanthinodera, &c. Type, Aptero- 
caiilus margmipennis, Fairm., = Ancistrotus servillii, Blanch. (^Acanthi- 
nodera bihamata, Bates). 
Chollides, id. 1. c. p. 264. Near Closterus,‘ with sub-pectinated antennae, 
with longer 3rd joint, and various other differences of degree. Ch. 
closteroides, p. 265, China. 
Zelogenes, id. 1. c. p. 267. Very like Cacosceles, but with antennae in 
the $ quite different, and scarcely reaching half the length of the elytra.

Paranoiciis, id. 1. c. p. 269. Differs from Jalyssus in the mandibles and

p. 270, Parana. 
Zooblax, id. 1. c. p. 274. Should found a new group near the ZEgoso- 
mites, uniting the characters of Navosoma, Strongylaspis, &c. Z. elatero- 
ides, ibid., Andamans. 
Navosgmopsis, id. /. c. p. 276. Differs from Aulacopus in its more 
slender antennae and legs, and in the thorax, which is like that of Navo- 
soma. For Aulacopus feistkameli, Buq.
