SOME NORTH AMERICAN INSECTS. 169 



18. E. convexus, Nob. (Journ. A.N. S.). With a good magnifier 

 the interstitial lines appear to have minute punctures; the third and 

 fourth, and fifth and sixth striae of the elytra are confluent before the tip. 



19. E. cardisce. Thorax rounded, convex, with an elongated lateral 

 fissure at base. — Inhab. U. S. 



Body, blackish: head with short, dense, prostrate, cinereous hair; 

 cljpeus elevated above the front, edge a little reflected : antennae, nearly 

 as long as the thorax, second joint shorter than the third : thorax ele- 

 vated, convex, with a slight violaceous tinge, and short, prostrate, cine- 

 reous hair ; regularly arcuated each side ; lateral edge hardly raised, 

 placed low down and obsolete before the middle ; basal margin pro- 

 foundly bisinuate, with an elongated fissure near the lateral angles and 

 a small prominence in the middle ; angles short, abrupt : scutel cordate, 

 having a basal fissure: elytra, striae deeply impressed, third and fourth, 

 fifth and sixth confluent before the tip ; very short hair ; interstitial 

 lines convex, minutely rugulous, an obsolete paler spot in the middle 

 and another beyond the middle : beneath slightly tinged with violaceous : 

 tihix and tarsi dark rufous.— Length three-tenths of an inch. 



I have taken it in Pennsylvania, and Dr Harris in Massachusetts. 

 It resembles convexus, S., but the thorax is much more narrowed be- 

 hind, &c. 



20. E. discalceatus. Clypeus prominent, triangularly impressed.— 

 Inhab. New Hampshire. 



Body hairy, rufous; discs of the thorax and elytra a little dusky: 

 head densely punctured ; clypeus prominent and obtuse before, with a 

 larger triangular indentation: thorax a little dusky on the anterior 

 margin; posterior angles a little excurved, obtuse, carinated line pro- 

 rectilinear edge almost to the anterior margin ; an impressed line at base ; posterior angles 

 carinate, rather acute: scutel convex, acute behind: elytra whitish, with striae of dilated 

 punctures ; tip black ; a narrow, black, sutural margin, and exterior edge, behind the middle, 

 black : /eei piceous : tarsi, fourth joint hardly shorter than the third. — Length over three- 

 tenths of an inch. 



Can this be the mixtus, Herbst ? It is the deusius of Melsheimer's Catalogue ? a name 

 preoccupied by Thunberg for a species of Ceylon. 



[This description Mr Say originally arranged immediately after that of E. mancus, in the 

 papers printed at New Harmony, during the summer of 1834, but omitted it with the follow- 

 ing remark :] 



Leconte says that it is the lugubris, Beauv.
