to a specimen which differs only by the punctures of the 
elytral strie being less distant. Allied to this, but appa- 
rently distinet is: 
17. Ochthebius lzvipennis, nu. sp.—Dark piceous-bronze, very 
convex, shining, of the same form as O. nitidus. Head with two large 
deep fovex, and a deep transverse suture. Prothorax with deep dorsal 
line, two small fovex each side in front of the middle, a deep impression 
near the apical margin, towards the anterior angle ; sides deeply lobed as 
in O. nitidus, pellucid margin broad, with an undulated outline. Elytra 
with deep, humeral fosse ; strizee obsolete, traced only by a few fine, dis- 
tant punctures near the base. Under surface piceous, legs testaceous. 
Length 1.3 mm.; .05 inch. 
Tejon, California; one specimen, Dr. Horn. It is possible 
that this is an extreme variety of O. nitidus, but until the 
intermediate forms are collected, it should properly be known 
under a different name. 
18. Ochthebius foveicollis, n. sp.—Closely resembles O. nitidus, 
but the elytra are longer, more obliquely narrowed behind, and the striz 
are composed of rather large, close-set punctures, not less distinct towards 
the tip. From 0. tuberculatus, it differs by broader prothorax, with larger 
lateral pellucid spot, and broader anterior lobes of the disc. Length 1.2 
mm.; .048 inch. 
Enterprise and Lake Harney, Florida, May; not rare. 
19. Ochthebius benefossus, ». sp.—Oval, moderately convex, 
bronzed, shining. Head sparsely punctured, with two very large fovez 
connected behind ; transverse suture deep. Prothorax wider than long 
(pellucid margin?) disc with the sides straight from the anterior angles to 
the middle, then strongly narrowed to the base (making a concave outline 
which must be filled with membrane in well preserved specimens) ; 
sparsely punctured, dorsal channel very deep, discoidal impressions deep, 
the posterior ones connected in a horse-shoe form. Elytra with strive com- 
posed of punctures distant from each other about their own diameters, 
basal fossze small. Beneath piceous, legs testaceous. Length 1.5 mm.; .06 
inch. 
New Jersey, Dr. Horn. Nearly of the same form as 0. 
nitidus, but different by the dise of the prothorax not being 
lobed at the side behind the front angles, as well as by the 
style of sculpture, which is more simple, and tends towards 
O. Holmbergi and allies. 
20. Ochthebius sculptus, n. sp.—Elongate-oval, greenish-piceous, 
slightly bronzed, shining. Head sparsely punctured with deep frontal su-
