ScOLYTIDiE. 
Chapuis, in his Synopsis des Scolytides (intended as the 
preface of a monograph), divides that tribe as follows (leaving 
Tomicus and its allies to Eichhoff) : — - 
Subtribe 1. CoPTONOTiDiE, having the sides of the pronotum 
strongly emarginate, and consisting of a single new genus and 
species. 
Subtribe 2. Phlgeotrupidas, characterized by the 7-jointed 
funiculus and annulated club of the antennae, the transversely 
reniform and coarsely granulated eyes, the externally spinulose 
tibiae, and the ovate or oblong-ovate body and large size. Grenera : 
Phlceotrupes (Er.), Phlceoborus (Er.), and one new genus. 
Subtribe 3. Hylesinidas, having the antennae inserted laterally, 
with the funiculus 5- or 7-jointed, with a compound club ; the 
eyes transversely reniform, minutely granulated; the tibiae 
spinulose externally ; and the body cylindrical or ovate, of small 
size. Genera: Hylastes (Ev.)yDolurgus iJ^Ac\\\\.)^Bothrosternus 
(Eichh.), Pagiocerus (Eichh.), Hylesmus (P.), Hylurgus (Latr.), 
Blastophagus (Eichh.), Dendroctonus {Ev.),Carphobo7'us (Eichh.), 
and six new genera. 
Subtribe 4. PnLCEOTRiBiDiE, having the antennae inserted in 
front, with 5-jointcd funiculus and a large club, sometimes freely 
jointed, sometimes solid. Genera: Phloeophthoi'us (Woll.), 
Phloeotribus (Latr.), and two new genera. 
Subtribe 5. Polygraphidas, with the antennae laterally in- 
serted, the funiculus 5-jointed, the club solid, the eyes bipartite, 
the tarsi cylindrical, slender, with the third joint neither bilobed 
nor dilated. Genus Polygraphus (Er.). 
Subtribe 6. Onychiida:, with antennae as in preceding, the eyes 
subcircular, the tibiae entire on the outer side, the tarsi elongate, 
with the first joint equal in length to the two following together, 
the third not dilated, the fourth longer and armed with strong 
claws. Comprises one new genus.
