length of the elytra; the last named connected with the sutural, which is 
entire. Front tibie with 3 large and 3 small teeth. Hind tibie with two 
rows of spines. Mesosternum smooth, with the marginal line curved in 
front. Prosternum with stria approximate, abbreviated in front, divergent 
behind. Length 3.8 mm.; .15 inch.

Cedar Keys; on the beach, rare. Also allied to the two 
preceding, and intermediate between them in the puncturing 
of the elytra. It differs chiefly by the first dorsal stria being 
prolonged behind, to within a short distance of the tip, as in 
S. fraternus, &e., though in a less degree. 
66. Epierus brunnipenmis Mars. Mon. Hister. (Ann. Ent. Soc. 
Fr. 1854), 697, fig. 18. 
Specimens found at Enterprise and Haulover, agree per- 
fectly with the description of this Mexican species, except 
that the elytra are piceous-black. 
and it is easily distinguished by the 4th and 5th dorsal striae 
being abbreviated in front, at about one-fourth from the base. 
67. Acritus salinus, n. sp.--Oblong-convex, shining black, indis- 
tinctly punctured. Prothorax without basal row of punctures. Elytra 
somewhat more distinctly puactured towards the suture, and slightly ru- 
gose behind; sides smooth. Prosternal striz strongly divergent in front, 
and twice as distant at the lobe as at base ; mesosternum with sub-marginal 
stria entire. Front tibis moderately dilated, inner margin slightly curved. 
Length .8mm.; .032 inch. 
Cedar Keys, found only on the ocean shore. 
68. Atzemius sculptilis Harold, Col. Hefte. iii, 86. 
A species found at Enterprise, agrees in all respects with 
the description of this Venezuelan insect. It is closely re- 
lated to A. cylindrus Horn, but differs by larger size, and by 
the interspaces of the elytra being strongly costate. Length 
4 mm.; .16 inch. 
69. Geotrupes chalybæus, n. sp.—Rounded-oval, convex, very 
shining, blackish-blue, with metallic gloss. Prothorax with a few scattered 
punctures ; sides much rounded, reflexed margin wider towards the base, 
which is distinctly margined. Elytra with rows of punctures in place of 
the striæ; sutural stria impressed, deeper towards the tip, which is armed 
with a small, acute sutural spine ; side margin broadly flattened and re- 
flexed near the base, narrower behind. Length about 21 mm.; .83 iach. 
Elytra 13.5 mm. ; .525 inch.
