1878. ] 395 [LeConte. 
46, [21.] Cryptobium lepidum, pn. sp.—Slender, less convex, 
ferruginous, shining, pubescence fine. Head oval, nearly as long as the 
prothorax, and wider than it, sides much rounded behind the eyes, which 
are rather large and convex ; sparsely, equably punctured, front not less so 
than the rest of the surface ; there are two long, but not deep frontal im- 
pressions. Prothorax with smooth dorsal stripe narrower than usual, lim- 
ited each side by a row of points, which becomes a slightly impressed stria 
towards the base ; sides rather sparsely punctured, almost in rows. Elytra 
distinctly longer than the prothorax densely, rather finely punctured. Ab- 
domen sparsely punctured. Legs paler, Length 3.8 mm.; .15 inch. 
Bosque County, Texas, Mr. G. W. Belfrage, two 2. The 
ventral segments are not impressed. A very small and pretty 
species, less convex than the others in our fauna. 
47. Peederus obliteratus, n. sp.—Elongate, slender, reddish-yel- 
low, shining ; head and last two abdominal segments black ; above yellow ; 
elytra blue-black ; antennze brownish at the middle. Head sparsely pune- 
tured, slightly wider than the prothorax ; the latter elongate-oval, feebly 
sparsely punctured, elytra not longer than the prothorax. sparsely but not 
coarsely punctured at the base, nearly smooth behind the middle. Dorsal 
segments very sparsely and finely punctured. Length 5 mm.; .20 inch. 
oS Sixth ventral cleft nearly to the base ; cleft wide, rounded at the an- 
terior extremity. 
Southern part of Florida, Dr. Palmer; Mr. E. P. Austin 
gave me a similar specimen as found at Cambridge, Massa- 
chusetts. This species is easily distinguished by the finer 
punctures of the elytra becoming gradually obliterated be- 
hind. 
Larger series of specimens have indicated to me the neces- 
sity of some modifications in the table of species of this 
genus published by Mr. Austin, (Proc. Bost. Soc. Nat. Hist. 
xix, 47); and I would propose to substitute for it the fol- 
lowing synopsis :
