not much elevated, dorsal and basal lines obsolete, and in the place of the 

 latter a broad, shallow, confiuently punctured depression, uniting with the 

 dilated lateral [118] margin . . Elytral striae impunctured, submarginal se- 

 ries of punctures indistinct; apex of the elytra sinuate. Body beneath and 

 thighs black, polished; tibia) and tarsi, reddish brown or bay. 



This insect is very common on grass during the warm days of summer. 

 It somewhat resembles H. herbivagus, and probably also H./aunus, Say ; but 

 is easily recognized by being entirely punctured, and sericeous above, by its 

 more rounded thorax, its dark thighs, and annulated antennae.

GENUS FERONIA. ' 



Subgenus Omaseus. 



The character's of this section of the Feronice have not yet reached us; 

 but comparisons with several European types enable us to indicate the fol- 

 lowing species. The first' only, appears to be apterous ; the remaining ones 

 are winged ; in this respect agreeing with the European specimens. All 

 of them (both native and foreign species) have the thorax somewhat heart- 

 shaped, truncate at apex and base, and not quite so wide as the coleoptra; 

 the dorsal stria is distinct, and dilated near the base; disc, near the basal 

 angles, indented, punctured, and with two abbreviated impressed lines. 

 The third interstitial line of each elytron has, generally, three large punc- 

 tures; one, near the base, contiguous to the third stria, the others contigu- 

 ous to the second stria, one on the middle and the third near the apex. In 

 a few the basal puncture is wanting. The submarginal interstitial line is 

 serrato-punctate within, the punctures approximated near the tip, and 

 somewhat ocellated. 



[123] These species do not agree entirely with any of the descriptions 

 of Say, though they approach to some of his Feronice in the Philadelphia 

 Philosophical Transactions. These insects are found imder stones. 



O. *bisigillaius. Black ; posterior thoracic angles rounded, each with an 

 annulated depression. 



Length eleven twentieths of an inch. 



Body glabrous, black. Antennas piccous toward the tip; palpi pale 

 reddish brown. Thorax broadest just before the middle, lateral margin 

 forming a regular curve, posterior narrower than the anterior margin ; pos- 

 terior angles not excurved, but obtusely rounded ; lateral basal lines very 

 much abbreviated, the external one obsolete, and between them is a deep,
