LeConte.] 394 [Feb. 1, 
smaller and indistinct upon the front. Prothorax with smooth dorsal stripe 
broad, sides strongly sparsely punctured. Elytra with rather large punc- 
tures arranged somewhat in rows. Abdomen sparsely finely punctured, 
tip and posterior border of segments brown; ventral segments brown. 
Length 6 mm.; .24 inch. 
3S and @ 2d ventral segment with a small tubercle bearing two small 
stout black setae resembling spines; <j‘? 8d ventral segment marked 
with a small fovea. 
The last joint of the maxillary palpi is about one-third the length of the 
ad joint. The elytra area little shorter than the prothorax. 
Tampa and Enterprise; three 9. On examining seven 
specimens, I find no difference in the ventral segments, ex- 
cept that in all of them the 2d (apparent) segment has a 
small transverse impression and fold, bearing spines; while 
in two of them the 5d segment has also a small round fovea 
at the middle,a little nearer the front than the hind margin. 
There is no difference in the size of the head. 
44. [18.] Cryptobium obliquum, n. sp.—Slender, cylindrical, 
shining, black ; antenne, palpi, and legs yellow. Head as long as the pro- 
thorax, distinctly wider, sides oblique behind the eyes, and broadly round- 
ed ; eyes rather large, convex ; sparsely punctured, front smooth, with only 
a few scattered punctures, the smooth space prolonged behind to between 
the eyes. Prothorax with smooth, dorsal stripe wide, not well defined ; sides 
sparsely, strongly punctured, punctures arranged almost in rows. Elytra 
coarsely punctured, here and there almost in rows. Abdomen sparsely 
punctured, nearly smooth towards the tip, which is brown. Length 6 mm.; 
.24 inch. 
3’ 3d ventral segment with a long, triangular setose process, rounded at 
tip; 2d and 3d segments not distinctly impressed. 
2 2d and 3d ventral segments, each with a very small bisetose fovea. 
Tampa; April, one pair. Quite different from C. lugubre 
by the form of the head. 
45. [19.] Cryptobium parcum, no. sp.—Cylindrical. shining, 
black, antenne, palpi, and legs yellow. Head as long as the prothorax, 
distinctly wider, sides oblique behind the eyes and broadly rounded ; eyes 
rather large, convex; punctured as in ©. obliquum. Prothorax with 
smooth dorsal stripe, sides sparsely coarsely punctured in rows. Elytra as 
long as the prothorax, coarsely punctured, here and there in rows. Abdo- 
men sparsely less finely punctured, tip brown. Length 6 mm.; .24 inch. 
@ 2d and 3d ventral segments not impressed 
Cedar. Keys; June, one °. Differs from C. obliquum chiefly 
by the less slender form, coarser punctures of the prothorax, 
and absence of ventral impressions.
