38 REVISION OF THE CICINDELZ OF THE UNITED STATES. 
GROUP VI. 
Contains species of robust form, and mostly of large size; above of the usual metallic 
brown colour, but sometimes of a fine copper or purple colour. The labrum is moderately 
large, three toothed, almost always prominent in the middle; with the lateral angles ob- 
tuse. The labial palpi of the male are pale, with the last joint black. The head and 
thorax are finely granulate, the former is finely striate at the sides, with scattered white 
erect hairs on the front: the latter is usually convex, narrowed behind, with erect hairs 
towards the sides. The elytra are punctured, very finely, sometimes hardly perceptibly 
serrate towards the tips, which are conjointly rounded in both sexes, with a small sutural 
spine. The markings are usually broad; the humeral lunule is always entire and pro- 
longed; the middle band almost rectangularly bent; the apical lunule entire: sometimes 
the whole outer margin is white. The under surface is with the exception sometimes of 
the middle of the pectus and abdomen, clothed with long coarse white hair: the anterior 
tarsi of the male are moderately broadly dilated. 
Species inhabiting sandy places, and seen only when the sun is brightly shining. This 
group seems closely related to group VIII., but in that the labrum is almost truncate an- 
teriorly, and the thorax is quadrate and less convex, and the elytra are more strongly 
serrate. Three principal forms. 
1. Elytra dull, middle band dilated on the margin: (labrum 3-toothed, prominent.) C. Ancocisconensis, venusta, 
generosa, formosa, latesignata. 
2. Elytra dull, spots not connected at the margin: (labrum 3-toothed, subtruncate.) C. vulgaris. 
3. Elytra shining, spots not connected: (labrum prominent, obsoletely toothed.) C. fulgida. 
C. Ancocisconensis affiliates by its markings with C. baltimorensis; while C. vulgaris is 
evidently by the labrum and form of body allied to C. purpurea, which differs by the en- 
tirely black palpi, the interrupted humeral lunule, and the not serrate elytra. 
15. O. Ancocisconensis supra sneo-brunnea, capite granulato, fronte albosetosa, utrinque subtiliter striata, tho- 
race conyexo, latitudine paulo breviore, postice subangustato, granulato, lateribus parce albo-setosis, elytris puncta- 
tis, ad apicem rotundatis obsolete serratis, lunula curvata humerali, altera apicali superne inflexa fascia angusta 
media obtuse refracta lineze marginali adjuncta albis; subtus viridi-eenea lateribus minus dense albo-setosis; labro 
sexus utriusque longiusculo, albo, tridentato. Long. -6. 
Mas palpis’labialibus articulo penultimo pallido. 
Harris, Family Visitor, (Cleveland, Ohio,) 2, No.39. Haldeman, Proc. Acad. Nat. Se. 6, 361. 
Found about the White Mountains, New Hampshire, by Dr. T. W. Harris, to whom 
I owe a fine series of specimens: a specimen was previously given me by Mr. Schafhirt, 
who found it in one of the public squares of Philadelphia. This species is very distinct 
from all other native species: the markings of the elytra resemble nearly in form those 
of C. repanda. Haldeman has stated that the maxillary palpi of the male are pale at 
base: this is undoubtedly an error of writing, as the labial palpi are meant.
