of their body, the proportions of the scutellum and of the sternal point; 
but the extremity of the narrower mandibles is obtuse and entire; 
the maxille have only two teeth and a pencil of hairs, and the men- 
tum is an elongated ovoid narrowed near the superior extremity, and 
its margin ciliated. All the tarsial crotchets are entire *, 
There, an axillary piece—the same observed in that place in Ceto- 
nia, or the epimera of M. Audouin—fills the space comprised be- 
tween the posterior angles of the thorax and the exterior angles of 
the base of the elytra.

The genus Melolontha of Fabricius will form our fourth and fifth 
sections. 
The fourth, that of the PHyLioruacti, is composed of Scarabeeides 
that closely approach those of the two last subgenera ; but the man- 
dibles are covered above by the epistoma, and concealed beneath by 
the maxille ; their outer side is alone exposed, without however over- 
lapping; the outer side presents none of the sinuses or dentations 
observed there in Rutela and other analogous subgenera. The an- 
terior edge of the labrum is exposed; it is sometimes in the form of 
a reversed and wide triangle, and most frequently tr ansversely lami- 
niform, and emarginated in the middle. The number of the anten- 
nal joints is not constant, and varies from eight to ten; the same re- 
mark applies to those of the club, and in several, with respect to this, 
the two sexes differ greatly. The ligula is entirely covered by the 
mentum, or incorporated with its anterior face, and the elytra are 
completely joined along the whole of the suture, characters which dis- 
tinguish these Insects from those of the fifth section. 
The family of the Anoplognathides of M. Mac Leay, and some 
other subgenera closely allied‘to some of those in the preceding sec- 
tion, will compose our first division. The epistoma is thickened an- 
teriorly, and either alone or with the labrum forms a vertical facet in 
the figure of a reversed triangle, the point of which rests on the men- 
tum. The latter is sonetimes almost ovoid, densely pilose, with the 
extremity either rounded or truncated and unemarginate ; sometimes 
it forms a transverse square, with the middle of the superior margin 
prolonged into a tooth, simple or emarginate. The maxille of some 
are terminated by a coriaceous or membranous lobe that is densely 
pilose, edentate, or with but very small teeth, situated near the middle 
of the inner side; those of others are entirely corneous, resemble 
mandibles, and are either truncated, or obtuse and entire at the end, 
or terminated by two or three teeth. 
Those, in which the mentum is almost ovoid and very hairy, and 
whose maxillze terminate in a similarly pilose, triangular lobe, with- 
out teeth, or with but very small ones situated near the middle of its 
inner margin, form two subgenera f.
