REVISION OF THE CICINDELA OF THE UNITED STATES. 59 
GROUP XXII. 
A very slender species, having the eyes very large and prominent, the head densely pu- 
bescent; the labrum short, slightly advanced in the middle and hardly perceptibly one- 
toothed; the palpi pale, with dark tips. The thorax is cylindrical, densely pubescent, 
with two subglabrous dorsal vitte. The elytra are white, the suture (slightly dilated in 
three places) metallic: the apex is obliquely narrowed and slightly sinuate (in the male,) 
and very finely serrate. The whole under surface is densely clothed with depressed 
white hair: the legs are extremely long, the tarsi being one half longer than the tibia: 
the claws are very large; the anterior tarsi of the male, though densely hairy beneath, 
are very slightly dilated. Seems related to group xu., but abundantly distinct. 
60. C. gratiosa, valde elongata, sneo-cuprea, capite thoraceque dense niveo-pilosis, hoc elongato, cylindrico 
vittis duabus dorsalibus subglabris, elytris ad apicem (maris) oblique subsinuatis, subtilissime serrulatis, niveis, 
vitta suturali breviter triramosa cuprea opaca; subtus virescens undique dense niveo-pubescens, antennis pedi- 
busque longissimis, unguiculis magnis, labro brevi albo medio paulo prominulo, vix obsolete unidentato. Long. -4.

Pensacola, Florida; the only specimen in his collection was most liberally given me by 
Dr. Schaum. 
GROUP XXIII. 
A very small cylindrical species, of bright metallic colour, with red legs. The labrum 
is moderately large, rounded in front and feebly bisinuate in the middle, with one very 
small tooth; it thus appears subtridentate: the head is glabrous, densely striate each side: 
the eyes are large and prominent. The palpi are pale with black tips. The thorax is cylin- 
drical, slightly hairy on the sides. The elytra are strongly punctured, with a white vitta 
far removed from the margin, and slightly lobed internally, extending from the humerus 
to the tip, where it bends around to the suture: tip obliquely narrowed (in the male) 
and slightly serrate. Body beneath hairy on the sides; anus testaceous. Anterior tarsi 
of the male very slightly dilated. 
61. C. lemniscata, elongata, cylindrica, supra fulgente-cuprea, capite thoraceque viridi-variegatis, granula- 
tis et rugosis, illo utrinque fortius striato, hoc cylindrieo, utrinque parce piloso, elytris fortiter dense punctatis, cy- 
lindricis ad apicem oblique angustatis, subserrulatis, vitta integra alba discoidali intus pone medium bilobata, et 
ad apicem ad suturam ambiente ornatis: subtus cyaneo-viridis, lateribus usque ad anum testaceum albopilosis, 
pedibus rufis; labro albo antice rotundato, medio obsolete subtridentato; palpis pallidis articulo ultimo zeneo.

Found by Dr. Webb of the Boundary Commission, and probably from the valley of the 
Gila. 
GROUP XXIV. 
Two very small species of dull sericeous surface, without humeral angles. Head large, 
glabrous, eyes very prominent, front much striate each side. Labrum moderate, rounded
