By E. Brenpet. 
SCYDMAENIDZA. 
Brachycepsis n. g. Head twice as wide as long, eyes large, prominent, palpi 
with the second joint obconical, the last a shorter conical subula, posterior coxze ap- 
proximate. 
B. fuchsii n. sp. Bright brown, sparsely and coarsely pubescent. Length, 
0.8 mm. 
Head transverse, vertex half as long as the entire width of the head, base and 
frontal margin equally wide, parallel, genze and lateral margin anterior to the eye 
equal in length and scarcely shorter than the eye, occiput convex, vertex from a line 
through the middle of the eyes to the frontal margin gradually depressed on either 
side leaving a slight longitudinal elevation in the middle and deepest near the supra- 
antennal tubercles in the form of a punctiform foveola ; antennal cavities very large, 
separatea by a clypeal septum, clypeus and labrum very short, transverse. Antenaz 
half as long as the beetle, joints 1—4 oblong, uniform, decreasing in s’ze, 5 —7 oval, 
decreasing in length, 8—10 transverse oval, gradually increasing, 11th as wide as 
roth, ovoidal. Prothorax, impunctate, as wide as long, wider than the head, sides 
anteriorly arcuate, posteriorly sinuate, narrowest in a line through the lateral fovez, 
which are situated in an ample longitudinal impression one-sixth of the length from 
the base, in the same distance in the middle is an obsolete transverse impression, 
Elytra very convex, not truncate at their apex, though the last segment is partly 
visible ; base narrowly elevated, each elytron bifoveate, the suture near the base ele- 
vated. Abdomen with six ventrals, coxze approximate, thizhs slender, the posterior 
ones more so,

Motschulsky’s Scydmcnus californicus may belong to this, but it is 
reported as being ‘/, of a Parisian line long, while this is 1 mm. shorter. 
According to the testimony of Dr. D. Sharp an unknown genus. I take 
pleasure in naming this insect in honor of its discoverer, my friend Carl 
Fuchs. 
Scydmzenus (?) minimus n. sp. Brown, slender, punctate, pubescent. Length, 
0.45 mm, 
Head widest in a line through the eyes, where it is one-third wider than the 
length from the base to the frontal margin, eyes large, not very convex nor promin- 
ent, equally distant from the base and the frontal tubercles, frontal margin nearly as 
wide as the neck, vertex broadly convex, antennal cavities large, leaving a narrow 
frontal septum between them, clypeus transverse triangular, Palpi with the third 
joint obvonical, thick, the last a thick subula, Antenne as long as the head and half 
of the prothorax conjoined, semigeniculate between the first and second ‘joints which 
are nearly equal in size, the first oblong, the second globular, 3—7 globular, half as 
thick as the second, gradually increasing in width, 8 as wide as the second, 9 and 10 
as long as the second and respectively two and three times as wide, truncate at the 
up, the last joint as wide as the roth, ovoid, truncate at the base. Prothorax as wide 
as long, sides evenly arcuate, base one-half wider than the neck, basal angles nearly 
rectangular, disk convex, minutely foveate near the basal angles and obsoletely trans-
