Tliis uutlior describes the following new gomaui and species ; — 
Cyrtostethus, p. 289. Distinguished from Lacus, Bonv., by the elevation of 
its prosternum behind, between the coxae, the penultimate joint of post, 
tarsi being less than the rest united, the hind border of the propleural triangle 
conspicuously shorter than the inner border, &c. C. throscoides, p. 290, pi. 13. 
fig. 3, Sarawak. 
Ceratus, p. 292. Antennae as in Diacerus, though not in the same division 
as that genus. C. insolitus, p. 293, pi. 16. fig. 3, Java, sodalis, p. 294, fig. 4, 
Macassar. 
Cladus, p. 432. Distinct from Fornax by its prosternum being very 
strongly excavated in front, with the prosternal projection very distinctly 
elevated behind, and by its considerably developed mandibles. The buccal 
organs are stated to terminate in long narrow branching filaments. C. maxil- 
laris, p. 433, pi. 21. fig. 9, Teapa, Cayenne, assimilis, p. 435, Ega. 
Euryaulacus, p. 445. Differs from Galbodema in its posterior coxae and 
strongly pectinated antennae. E, carbonarius, p. 446, pi. 22. fig 2, Cayenne, 
luctuosus, p. 447, fig. 3, Minas Geraes. 
Jlodocerus, p. 449. Third joint of antennae of same size as 2nd, both 
together scarcely equalling the 4th ; 4th joint of post, tarsis horter than the 
rest united. H. malaisiensis, p. 450, pi. 22. fig. 4, Singapore. 
Dicladus, p. 451. Antennae very short, strongly bipectinate ; propleural 
triangle reduced to a simple band in the anterior 3rd. D, bipectinatus, 
p. 452, pi. 22. fig. 5, Malacca. 
Tachycnemis, p. 454, Marginal furrow of propectus shallow, not limited 
internally but distinctly terminated behind, before tho posterior angles, by 
the hinder margin of the propleural triangle. T. nigra, p. 455, pi. 22.
