references to Bateses species are made from information received 
from that author. The insects attributed by Chaudoir to his 
two groups above mentioned are kept separate in this Record 
from eacli other and from the Pericalides of Bates, for facility of 
reference. 
Chaudoir considers that the Thyreopterides form a transition 
to the Anchomenides , the members of his genera Oxyglossus and 
Stenognathus having been placed by Dejean in AnchomemiSj &c., 
from which they are stated to differ in having the ligula horny, 
quadrisetose at the apex, and never free, in the shortness of 
their tibial spurs, and in the form of the apex of their elytra. 
He purges the type genus, Thyreopterus (p. 141), of all but four 
species. 
Chaudoir, 1. c. p. 122, is inclined to refer Burydera anchomenoules (Gory 
et Oast.) as a close ally to his Glyphodactylus madagascariensis] at all events, 
ho concludes that it is no true Eurydera. Ilis type appears to be very im- 
perfect. The genus ThysanotuSj which he proposed for its reception, seems 
not to ho admitted. 
Mnrmolycc, according to Chaudoir, 1. c. p. 133, must be referred to tlie 
I'hyrdcypterides, as an aberrant form, near Eurydera and Serrimargo. lie con- 
siders the form of the metasternal episterna of secondary importance. 
Chaudoir, 1. c., characterizes the following new genera and species : — 
Ferm ( = Fhlceotherates^ Bates), p. 119 ( Coptodera, Bej., pars). Differs from 
Stejiognathus (Chaud.) in its more abbreviated form and the toothed base of 
its claws. Sp. : F. gagatinus (Dej.) ; E. qiiadricollis, sp. n., p. 121, Mexico. 
Bt'achichila, p. 123. Distinguished from its allies by its short transverse 
labrum ; it has rather the facies of Ferus, except in coloration and marking, 
wherein it suggests Mochtherus. Sp. B. hypocrita^ sp. n., ibid., Hong Kong. 
Coptoglossus, p. 124. Of the build of small Fe?'us, but rather narrower, 
especially in the thorax, and with penult, joint of max. palpi shorter. Sp. 
C. sulcatulus, sp. n., p. 125, Melbourne, Australia. 
7'antilluSy 1. c. p. 126. Also allied to Ferus. Sp. T. brunneusy sp. n., ibid., 
Ceylon. 
Pristolomus, 1. c. p. 128. Close to Stenognathus, but differing in having 
the apex of the ligula more produced than in Oxtjglossus, and the lateral 
margin of the elytra denticulated, and ending in a sharp projecting tooth at 
the outer posterior angle. Sp. P. dentifer, sp. n., ibid., Columbia. 
Sinurus, 1. c. p. 129 (no differential characters given). Sp. S. opacus, 
sp. n., p. 130, Sarawak. 
Pristacrus, 1. c. p. 131 {Eurydera, Casteln., pars). Differs from Eurydera 
in its wide ligula and narrower and more parallel elytra, which have no 
widely depressed lateral border and no spine at the apex. Sp. P. laticollis 
(Casteln.). 
Se7'rimargo, 1. c. p. 134 ( Thyreopterus, Schaum, pars). The nearest ap- 
proach to Mormolycc. Sp. S. guttiger (Schaum), S. verrucifer (Chaud.). 
Peripristus, 1. c. p. 135 ( Thyreopterus, pars). The more prominent eyes, 
the contraction of the thorax behind, the toothing of the whole outer margin 
of the elytra, and the unrounded angle at their apex, distinguish this genus 
from Thyreopterus, The lobes of the mentum not being truncate and the
