1878. | 427 [LeConte. 
Head scabrous, bent perpendicularly downwards. Prothorax scabrous- 
punctate, very convex, a little longer than wide, subsinuate and broadly 
rounded in front, feebly rounded on the sides, truncate at base; at the 
sides, feebly emarginate at the middle ; front angles rounded, hind angles 
rectangular. Elytra with the basal margin elevated, finely scabrous near 
the base, roughness gradually becoming very fine and dense punctuation 
behind. Antennz slender; Ist, 3d and 4th joints equal in length, 2d 
shorter. Maxillary palpi with the 2d joint long, triangular, 3d shorter, 
triangular, not narrower, 4th not wider than 2d and 3d, elongate, cultri- 
form, three times as long as its width at the base. Length 12 mm.; .48 
inch. 
¢ Front tarsi with 4th joints broadly dilated, spongy beneath ; 4th joint 
not narrower, deeply pilobed. @ wanting. 
Enterprise; very rare in dead oaks. The prothorax is 
more prominent and convex in front than in D. liturata, and 
overhangs the head, almost as in Lymexylon sericeum. 
130. Mordella fascifera, n. sp.—Piceous, pubescent, with 
cinereous hair. Prothorax with three large spots, extending from 
near the base to the middle, fuscous. Elytra with the anterior 
third (divided by a narrow sutural gray line), and a broad oblique 
band behind the middle fuscous ; the band forms at the suture an 
angle directed forwards. Beneath thinly pubescent ; base of an- 
tenn, palpi and legs piceo-testaceous. Length 2.8 mm.; .09 inch. 
Cedar Keys; one specimen. The form is somewhat ro- 
bust as in WM. triloba,and the anal process is long and slender. 
The length is given exclusive of the process. 
151. Mordella angulata, n. sp.—Black, finely pubescent, 
elongate. HElytra with two cinereous somewhat oblique trans- 
verse spots, one at the anterior third, the other at the second 
third of the length ; these spots are each connected at the inner 
end with an oblique line running backwards to the suture. 
Anal process long and slender. Length 2.7 mm.; .11 inch. 
Lake Ashby; one specimen. Longer and narrower than 
the preceding, having the form of many Mordellistene, or of 
Mordella diseoidea. 
132. Mordella triloba Say.—Specimens taken at Enterprise, in 
May, differ from Northern specimens by the elytral fasciz being much nar- 
rower ; and the anterior one is strongly angulated so that the basal spot 
becomes acutely triangular ; the humeral region is dull ferruginous. I am 
unwilling to describe it as distinct, but regard it rather as a well-marked 
variety.
