PHREATUS. 
Caput exsertum, subquadratum, fronte impressa. Oculi majusculi, pro- 
minuli. Antenne crassx, basi tectee, clava vix conspicua, biarticulata. 
Prothorazx elongatus, parallelus, disco lineis duabus impressis, lateribus 
submarginatis. Elytra subdepressa, oblonga. TZibie trigonatee, antice 
breviter calcarate. Zursi breves, incrassati. Corpus angustulum, sub- 
depressum. 
The short tarsi, combined with the biarticulate and but slightly 
marked club of the antennz, will at once distinguish this from any 
other genus of its subfamily. In other respects, its long prothorax, 
which is not much shorter than the elytra, with its two longitudinally 
impressed lines, are peculiarly characteristic. 
Phreatus rigidus. (PI. V. fig. 3.) 
P. piceus, nitidus; elytris striatis, interstitiis uniseriatim punctatis, basi 
triangulariter elevatis. 
Hab. Ega? 
Pitchy, shining; head subquadrate, a longitudinal impressed line on 
each side, connected in the middle by a transverse one; eyes black, 
oblong, prominent; antenns robust, the basal joint covered at its 
insertion, slightly incrassate, the last two joints forming a narrow, ovate 
club; prothorax elongate, truncate in front, the sides nearly parallel, 
narrowly margined, the disk with two strongly impressed longitudinal 
lines, and at about two-thirds of its length posteriorly a large deep 
fovea on each side near the margin; scutellum punctiform; elytra 
slightly depressed, subparallel, a triangular raised space at the base, 
behind which on each elytron are two strongly marked, nearly impunc- 
tate striz, the interstices (three) with a single irregular line of punc- 
tures, towards the side two or three other lines; legs robust, femora 
clavate; tibise trigonate, the anterior with a single spur, the posterior 
lobed internally at its extremity; tarsi short, terete. Length 1 line.

Caput insertum, subquadratum, lateribus reflexis. Antenne basi tecte, 
clava biarticulata, sulcis antennariis brevibus. MZentum transversum, 
antice angustatum, ciliatum. .Prothorax subquadratus, disco irregu- 
lariter costato, lateribus marginatis. Elytra carinata. Tibie breves, 
subtrigonate, mutice. Twrsi articulis primis brevibus. Corpus ovatum,

Coniophea is a very distinct genus, but which, except for its 
antennary grooves and the large basal segment of the abdomen, 
would approximate to Bitoma. In Erichson’s arrangement it will 
stand near Eulachus, which has no antennary grooves, the coste of 
the prothorax simply longitudinal, and the body subcylindrical. In
