34 REVISION OF THE CICINDELZ OF THE UNITED STATES. 
wanting. Pectus and legs sparsely clothed with white erect hairs: outer side of middle 
tibize densely pubescent. Tarsi of male moderately broad. 
Species of sandy and bushy places, of active and vigorous flight, appearing only when 
the sun is shining. 
C. pulchra seems related to C. severa, but that species is elongate and has the base 
of the palpi pale: the tips of the elytra are in it finely serrate and somewhat obliquely nar- 
rowed, the body is much more hairy beneath; and finally the middle tooth of the mandi- 
bles is smaller than the others, while in C. pulchra as in the others of this group they are 
nearly equal in size. 
The species, which so far as known to me are North American, may be divided as 
follows. 
Front hairy, elytra polished, margin of a different colour. Sp. 6. 
Front hairy, elytra not polished. Sp. 7-9. 
Front glabrous, finely striate each side; elytra not polished. Sp. 10. 
6. C. pulchra, capite purpureo cupreoque variegato, fronte punctata pilosa utrinque parce striata, thorace con- 
vexo cupreo levigato, marginibus omnibus cyaneis, elytris cupreis politis antice punctatis, sutura margineque cya- 
neis, gutta humerali, alteraque submarginali ad medium albis, seepe deficientibus; subtus cyanea, vel viridis, lateri- 
bus longe albo-pilosis. Long. -73.

Found on the arid table lands adjacent to the Rocky Mountains from the Platte River 
to the Rio Grande. A species of strong and vigorous flight, not common and very diffi- 
cult to capture. 
7. C. Lecontei, supra cupreo-purpurea, haud nitida, fronte fortiter striata parce punctata et pilosa, thorace convexo, 
vage at distincte rugoso, elytris brevibus convexis obsolete punctatis versus suturam seriatim vage foveatis, maculis 
marginalibus seepe coheerentibus albis, subtus obscure cyanea ad latera pilosa; labro sexus utriusque albo tridentato.

Wisconsin, near Green Bay, Mr. Guex: near Racine, Messrs. Hoy and Barry; Fort 
Gratiot, Dr. Kirtland. Very closely allied to the next, and not differing in form, in any . 
respect: the labrum is however white in both sexes, and the thorax is sparsely but dis- 
tinctly rugous. The humeral lunule is frequently entire, the medial spot is triangular 
and large, very often connected with the humeral and apical lunules: the latter recedes 
anteriorly from the margin, and is prolonged forwards. Sometimes the humeral lunule 
is reduced to a post humeral marginal dot. Varieties will doubtless occur in which the 
spots are small, or even entirely wanting. 
8. C. rugifrons, cyaneo-viridis vel nigra, fronte fortiter striata parce punctata et pilosa, thorace convexo, haud 
vel vix rugoso, elytris brevibus convexis obsolete punctatis, versus suturam seriatim obsolete foveatis, gutta post- 
humerali, macula triangulari media, lunulaque apicali seepe coherentibus, seepe autem deficientibus albis; subtus 
ad latera pilosa; labro tridentato maris albo, feminee nigro-piceo. Long. -48—-5.
