completely sunk in the pro-thorax. The /rons is small in proportion to the 
size of the head. The epistome is large. The antenne are long and four- 
jointed. 
The Lpistome (Fig. 9).—The epistome in Lyctws is not so well defined as 
in Anobiwm, and I have thought it best to consider the epistome as consist- 
ing of two parts—a stouter definite region adjoining the frons, and a 
thinner less definite and flexible region partly surrounding the clypeus. 
The Clypeus.—This structure is quite different from that of the Anobud 
type. It bears numerous bristles and is narrower posteriorly, contrasting 
with the Anobiid which is broadest posteriorly. 
The Labrum in Lyctus is fringed with very fine bristles totally different 
from those of Anobiwm. They form a fringe round the anterior border, and 
are finer and longer than the Anobiid labral bristles. The labral hooks 
call for no special comment.

Frons and epistome of L. brunneus. 
The Mandibles are smaller than in the Anobiid type, but are otherwise 
similar. 
The Maxille and Labiwm differ from those of A. domesticum, but not 
ereatly. 
The Lacinial lobes in Lyctus are broader than those in Anobiwm, and 
in Zyctus bristles are absent on the submentum. In the Anobiid type the 
submentum bears bristles. The maxillary palps in Lyctws are three- 
jointed, the labial palps one-jointed. 
The Thorax (Fig. 7). 
The Pro-thorax in Lyctus is remarkably broad. I have been unable to 
make out other than a scutellar fold. It bears a pair of spiracles. 
The Meso-thoraz is much narrower. It has no prescutal fold and the 
pedal fold is small. 
The Meta-thoraz has no pedal fold. The /egs, or feet, are three-jointed 
and hairy.
