have much pleasure in dedicating this species to a gentleman who has devoted a great share of his
attention whilst in Australia to the collection of minute and singular species of Coleoptera, including also the
following species (exhibited at the same Meeting of the Society by Mr. Pascoe; see Proceedings, 1869,'p. xv).

Of this remarkable insect M. Du Boulay only obtained a single individual, so that I have not been able to
examine the parts of the mouth, the head being entirely retracted within the prothoracic cavity. The antennis
have the basal joint compressed and somewhat kidney-shaped, the following joint being attached below the apex;
this second joint is longer than thick, having, as it seemed, a transverse impression close to the base (if, indeed^
the minute basal portion be not the real second joint ) ; the following joint is slightly longer than thick, but the
five following are very short and transverse. The club is elongate, narrow, slightly curved, with the sides
nearly parallel, and rounded at the top. When at rest, the antennse, including- the terminal joint, are received
w-ithin the fossulated anterior angles of the prothorax, outside the lateral parts of the head. The palpi must be
very minute, as no portion of them could be perceived in the unique individual e.^amined, although small spaces,
evidently the labium and mandibles, were visible. The prothorax is transverse, very much broader than the
head, and nearly as broad as the shoulders of the elytra; it is covered with minute elongated setigerous punctures
; the fore margin is acutely elevated, with the lateral angles excavated beneath for the reception of the
antenna;; the lateral margins are very slightly curved. The elytra are large and subquadrate, very irregular on
their dorsal surface, especially the anterior half, the middle of which forms a deep and nearly square impression,
the shoulders gradually elevated into a smuated ridge, outside of the centre of which is a deep circular impression
only visible when the body is seen laterally. The impressed portion is marked beyond the scutellar
region (the scutellum itself being wanting) by two deep curved lines, near the outer termination of each of which
is a patch of short luteous seta;, the space between which and the hind margin of the pronotum is occupied by a
triangular raised space on each elyti-ou, which is separated from the humeral region by a longitudinal line; this
basal portion of the elj'tra is rudely punctured, hut their terminal half is covered with very delicate longitudinal
striola;, each elytron having a raised boss near the lateral margin opposite the hind femora. The legs are long,
but, in consequence of the depth or the thickness of the body, they fold up and lie against the sides of the sterna
when at rest, the tarsi folding back, and being received in the long groove in each tibia;, which reaches as far as
the external angle with which each is provided. The prosternum is greatly dilated in front, and truncated
behind, separating the fore legs from each other by a narrow space. The mesosternum is very short and transverse,
with the middle legs more widely apart at the base than the fore ones, whilst the metasternmn is very
large and transverse, with a central impressed longitudinal line ; the middle legs being inserted far apart, with
the coxa but very slightly developed. The basal segment of the abdomen is large, the four following very short,
and the terminal joint large, aud rounded at its extremity.
This species seems to connect Ectrephes with certain Histerida;, such as Hetmius, and especially with
Terapus (De Marseul, Ann. Soc. Ent . France, 1862, p. G80, pi. VII.)
