The TetragonoderidcB are characterized as a special group having 
the terminal hook of the maxillae very slender, sharp, and curved, and 
surmounted by a rather large lobe, which is clothed with hairs. They 
include Cyclosomus, Tetragonoderus, Mnuphorus^ and two new genera: — 
Tilius,-pY>. 29 & 71, with intermediate tarsi simple in both sexes, and 
no tooth to the mentum. For Lionychus holosericeus, Chaud., Dromius 
ohscurellus^ and T. suhsericeus^ sp. n., p. 73, S. Africa. 
Peronoscelis, pp. 29 & 66. Paraglossae slightly pubescent, only 
laterally attached to the ligula, and evidently overtopping it. For 
Tetragonoderus velutinus, Mots., &c., and P. variipennis, p. 59, Amazons 
and Bolivia, /(377^omZ^s, p. 60, Ega, mexicanus, p. 62, Mexico, oxyomus, p. 66,

Various corrections and observations are made with regard to described 
species ; Crossonychus viridis, Dej., Chaud., is a Tetragonoderus ; Mnu- 
pJiorus^ Chaud., is characterized, p. 69 ; and the following new species 
are described : — 
Tetragonoderus obscurus, p. 36, Madagascar, subsulcatus, p. 37, Island 
of Pemba, gahonicus, p. 40, Gaboon, insignicOlUs^ p. 42, Natal and Zanzi-

Mnupliorus discophorus, p. 69, Simla. 
Nemotarsus, Lee., corrected to Nematotarsus^ is fully recharacterized, 
pp. 74-76, and stated to be only capable of being placed near the Tetra- 
gonoderides^ from which it is distinguished by the constriction of the 
base of the head, the absence of the lobe over the terminal hook of the 
maxillae, &c. The following new species are described : — 
Nematotarsus disciger^ p. 76, Rio Janeiro, interruptus, p. 77, Minas 
Geraes, scutellaris, p. 79, Ega. 
Sarothrocrepis^ Chaud. Lebia luctaosa, Nowm., is referred to this 
genus ; L. benejica, tridens, and civica, Newm., with Oymindis inquinata, 
Er., come very near it, but constitute a new genus “ que j’ai nommd 
Lebiomorphe Rhinochita levrati, Montr., is also allied. Another special 
group is foreshadowed. L. c. p. 80. 
Mimodromius (g. n.), referred to Ohaudoir by E. C. Reed [Zool. Rec. 
xi.p. 255], must be attributed to the latter, and additional characters are 
given, distinguishing it from Cyanotarus^ Reed ; Callida guttula and ? 
Dromius nigro-testaceus^ Sol., are included in it, allso M. parallelus^ and 
obscuripennis, p. 107, ? Chili, opacicollis, p. 108, Chili, phceoxanthus, ibid,
