axis of the tibia, a distinct, but feeble sinuation of the apical margin 

 anterior to the insertion of the tarsus, adjacent to the fixed spur. 

 Claws rather slender, tooth small and slightly intramedian. 



One species enters this group. The sinuation of the apex of the 

 % hind tibia allies it with the congriia gi*oup between which and the 

 longitarsis group it naturally takes its place. 



The species was made the type of a distinct genus (Gynnis) by 

 Dr. LeConte, but the characters are too feeble to admit of its reten- 

 tion. 



15. li. clisi>a.r Burm. — Elongate, cylindrical, pale rufo testaceous, thorax 

 somewhat darker, head fuscous or piceous; surface moderately shining. Clypeus 

 testaceous, semicircular, concave, margins rather widely reflexed, punctures 

 rather coarse, not closely placed, front more closely punctate, the punctures 

 coarser in the female. Thorax short, scarcely narrower at apex than base, sides 

 regularly arcuate, margin obsoletely crenate, disc with moderately coarse punc- 

 tures rather closely placed, coarser and deeper in the female. Elytra very 

 coarsely and closely punctate, the discal costfe fine and indistinct, the submar- 

 ginal slightly distinct posteriorly. Pygidium coarsely sparsely punctate, shining, 

 punctures closer in the female. Metasternum sparsely, coarsely punctate, with- 

 out hairs. Abdomen more sparsely and finely punctate. Claws feebly arcuate, 

 the tooth small and slightly intramedian, slightly longer in the female. Last 

 joint of maxillary palpi short fusiform, slightly impres.sed. Length .37 — .48 

 inch; 9.5 — 12mm. 



Male. — Antennal club as long as the stem. Abdomen vaguely 

 impressed at middle, last segment slightly concave, a small dentiform 

 process projecting backward from the anterior margin. Inner spur 

 of hind tibia fixed and moderately long. 



Female. — Antennal club shorter than the funiculus. Spurs of 

 posterior tibise long and slender, the tarsi distinctly shorter than in 

 the male. 



Variations. — Burmeister describes a specimen as fuscous, this is 

 due more to a bad state of preservation than an actual difference of 

 color. 



In adopting the Burmeister name for this species (formerly Gynnis 

 debilis Lee.) in place of that determined by Dr. LeConte as dispar, 

 it is proper that the reasons should be given. 



Burmeister indirectly compares the present species with gracilis 

 (volvula Lee), a comparison not at all applicable to clemens (dispar 'I 

 Lee.) ; the thorax is in the female more coarsely and deeply punc- 

 tured than the male, a character very evident in the species under 

 consideration ; the shorter clypeus of the female is also noted by 

 Burmeister.
