II. Anteniije of ten joints. 
A. Last three joints of antennae very large, elongated. 
* Protliorax as broad as the elytra, its disk gihbose. 
Oligomerus (Redt.). 
t Prothorax narrower than the elytra, its disk not gihbose. 
Amphiholus (g. n.). 
B. Last three joints of antennae large, compressed, dilated Interiorly. 
Gastrallus (Dural). 
The XglMinaires include seven genera, namely (/. c. p. 225) : — 
I. Prothorax not excavated beneath for the reception of the head. 
A. Antennae pectinated ( $ ) or flabellated (d)* Ptilimis (Geoff.). 
B. Antennae simply serrated Ocliina (Steph.). 
II. Prothorax more or less excavated beneath. 
A. Last three joints of antennae larger than the intermediate ones. 
Tripopitys (Redt.). 
B. Last three joints of antennae not perceptibly larger than the inter- 
mediate ones. 
* Metastemum with no projecting ridge behind its anterior margin. 
a. Prothorax, seen from above, forming a transverse square. 
Metholcus (Duval). 
h. Prothorax distinctly narrowed in front. 
ot. Last joint of palpi oblong, subfusiform. Calypteriis 
/3. Last joint of palpi more or less dilated and truncate at apex. 
Xyletinys (Lat.). 
t Metasternum with a fine transverse ridge behind its anterior margin. 
Pseudochina (Duval). 
The Mesoccelopaires, the first section of the Dorcatomiens, includes only 
two genera, namely (/. c. p. 311) : — 
Body oblong ; elytra with a lateral stria ; prosternal lamina carinulate ; 
posterior epimera apparent ; first ventral segment forming a narrow border 
beyond the transverse pits Mesothes (g. n.). 
Body ovoid j elytra with no lateral stria ; prosternal keel simple ; epimera 
not apparent Mesocoelopus (Duval). 
Of the DorcatomaireSy Mulsant and Rey admit four genera (p. 328), 
namely : — 
I. Metasternum not produced forward between the intermediate coxae. 
Theca (Mills.). 
II. Metasternum produced between the intermediate coxae in a lamina. 
A. Body oval or suboval . Dorcatoma (Herbst). 
B. Body short, subhemispherical. 
* Eyes deeply incised, subbilobate Pnneatoma (g. n.). 
t Eyes scarcely sinuated on the lower part of their inner margin. 
Amhlytoma (g. n.). 
Anohium. Mulsant and Rey (Col. de France: T^ri^diles, pp. 66-67) suggest 
the separation from this genus of several subgenera : Dendrobium {A. den- 
ticolle and A. peciinax)^ Anohium (A. domesticum'), Neohium (A. hirtum and 
iomeniomm)^ and Artolium (A. paniceuni). 
Xestohium plumheum (111.) forms the type of a new subgenus, HypensuSj 
according to Mulsant and Rey, 1. c. p. 129.
