By E. Bkendel. 



SCYDMiENID^. 



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 coxk 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, gense 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 punctitorm foveola ; antennal cavities very large, 

 separated by a dypeal ^eptum, clypeus and l;ibruni very short, transver^e. Anten.iiv 

 half as long as the beetle, joints I — 4 oblong, uniform, decreasing in sze, 5^7 oval, 

 decreasing in length, 8 — 10 transverse oval, gradually increa-ing, nth as wide as 

 loth, ovoidal. Prothorax, impunctate, as wide as long, wider than the htrid, sides 

 anteriorly arcuate, posteriorly sinuate, narrowest in a line tlirough the lateral fovece, 

 which are situated in an ample longitudinal impi es-ion one-sixth of the length from 

 the base, in tlie 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, coxk approximate, thighs sk-nder, the posterior 

 ones more so. 



Santa Cruz, California. Charles Fuchs. 



Motschulsky's Scydmwnus cali/ornicus may belong to this, but it is 

 reported as being '/s of 'i Parisian Hne long, while this is i 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. 



Scydmaenus (?j 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 betw^een them, clypeus transverse triangular. Palpi with the third 

 joint obconical, thick, the last a thick subula. Antennee as long as the head and halt 

 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 

 tip, the last joint as wide as the loth, 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 tians-
