deuxième et troisième articles sont globuleux et n’égalent 
pas, réunis, la longueur du quatrième. En outre la forme 
du thorax, nullement rétréci en avant, un peu subquadran- 
gulaire, avec ses angles postérieurs et son bord antérieur 
relevés en carène, donne à ces insectes un facies tout parti- 
culier. | 
Une seule espèce dans notre faune. Ne connaissant pas 
cette espèce, J'en donne ici la description telle que faite par 
le Dr Horn dans sa monographie *. k 
21. Entomophthalmus rufiolus Lec.—Form moderately 
elongate, slightly narrower behind, ferrugineous, modera- 
tely shining, sparsely clothed with very short fulvous pu- 
bescence ; antennæ slender, feebly serrate, nearly as long as 
the entire body ; head coarsely not densely punctuate, eyes 
feebly emarginate in front ; clypeus at base a little wider than 
the space between it and the eye; prothorax a little wider 
than long, sides straight and parallel, scarcely at all rounded 
at the front angles, hind angles feebly carinate; disc mode- 
rately convex, obliquely depressed each side within the hind 
angles, a feeble ante-scutellar carina terminating in a feeble 
median depression extending two-third to apex; surface 
coarsely not densely punctured ; anterior supplementary ca- 
rina very short, the posterior extending three-fourths to 
apex; juxta-sutura sulcus deep, slightly wider posteriorly, 
the outer carina well developed and entire; elytra vaguely 
striate with coarse, moderately closely placed punctures sub- 
striately arranged, the intervals with finer punctures ; body 
beneath rather coarsely and closely punctuate; prosternum 
narrow between the coxæ, prolonged and acute; metaster- 
nal episterna narrow; hind coxæ much dilated internally ;
