REVISION OF THE CICINDELA OF THE UNITED STATES. 45 
beaucoup plus étroite, plus paralléle et la lunule du milieu se dilate sur le bord externe, de maniére & rejoindre 
presque la lunule humérale et descend extérieurement aussi bas que la branche antérieure de la lunule apicale; de 
plus la lunule du milieu, partout d’égale largeur, descend obliquement jusqu’ au deux tiers de la largeur de l’élytre; 
les jambes sont trés longues et gréles. Le dessous du corps est couvert de poils blancs trés serrés.’ 
GROUP X. 
Moderate-sized, subcylindrical, but somewhat robust species, with sericeous surface 
rarely with any metallic gloss. Head glabrous, striate each side. Labrum short with 
one prominent, and two obsolete teeth. Palpi pale with darker tips in the male or in 
both sexes. Thorax quadrate, rounded, or subcylindrical, hairy on the sides. Hlytra 
not serrate, conjointly rounded in the male, with the suture slightly retracted in the fe- 
male. The medial band is oblique, and long: the humeral lunule is also prolonged: these 
markings are frequently connected by a broad white marginal band, but the white is se- 
parated from the outer edge by a stripe of black, which is quite conspicuous. From this 
it results, that in the varieties with obsolete markings the medial band does not reach the 
margin as usual. The under surface is metallic green, slightly hairy on the sides; the 
anus is black: the tibize are usually testaceous at base. 
The middle tooth of the mandibles is smaller than the others, though not so conspicu- 
ously so as in group XXI.
