60 REVISION OF THE CICINDELZ OF THE UNITED STATES. 
in front, with a prominent medial tooth limited each side by a slight incisure, palpi pale 
at the base in both sexes. Thorax long, cylindrical, slightly narrowed behind, with faint 
transverse impressions, sides finely sparsely pubescent. Elytra narrowed in front, humeral 
angles none; tip rounded, not serrate, sutural spine large, retracted in the female, promi- 
nent in the male; coarsely punctured, sparsely clothed with short hair: the markings are 
a very narrow apical lunule, a discoidal dot and marginal line representing together the 
medial band, and in one species an anterior discoidal dot, which is the tip of the humeral 
lunule, or in the other species a very slender imperfect lunule. Wings rudimentary, unfit 
for flight. Body beneath hairy at the sides, anus testaceous; legs very long, anterior tarsi 
of the male feebly dilated. 
62. C. celeripes, fusco-zenea, obscura, sericea, capite thoraceque granulato-rugosis, illo utrinque fortius striato, 
oculis maximis, hoc cylindrico, latitudine sesqui longiore, postice subangustato, lateribus rectis parce pilosis, elytris 
fortiter punctatis, antrorsum angustatis, humeris nullis, ad apicem late rotundatis haud serratis, spina suturali 
magna, guttis utrinque discoidalibus (ad trientem a basi et apice positis) posteriore interiore, linea marginali ad 
medium, lunulaque apicali tenui albis; subtus viridi-genea, lateribus albo-pilosis, trochanteribus anoque testaceis; 
labro albo antice rotundato, medio bisinuato et unidentato, palpis sexus utriusque ad basin pallidis. Long. -3—-35. 
Mas sutura integra; femina sutura retracta.

Found near the branches of the Kansas River, and between the latter and the Platte: 
in the month of May I found it extremely abundant, and a further suite of specimens from 
Fort Riley I owe to the kindness of Dr. Wm. A. Hammond, U. 8. A. Specimens occur in 
which the discoidal dots are wanting, and only the apical lunule and marginal line re- 
main white; sometimes even the latter disappears. 
Nearly allied, but perhaps only a variety, is the species indicated by me (Proc. Acad. 
Nat. Sc. 6, 66) upon a single elytron brought from the Creek Boundary by Dr. Woodhouse : 
the punctures are not so large or so deep, the pubescence, if any existed, has been removed 
by the alcohol in which it was preserved: the humeral lunule is slender, curved, and entire; 
the marginal line sends off an internal branch at the middle running towards the discoidal 
spot, and the apical lunule is rectangularly inflexed at its anterior extremity. Among 
the specimens sent by Dr. Hammond is one, however, which corresponds exactly with the 
elytron above mentioned: in form it agrees exactly with C. celeripes, and by close inspec- 
tion a few hairs may yet be perceived on the elytra, the punctures are less deep, and the 
tibize, tarsi, and tip of the femora are testaceous with green metallic lustre. On this ac- 
count I am induced to separate it as a distinct species. 
63. C. cursitans, elongata, zneo-fusca, sericea, elytris modice punctatis subglabris, antrorsum angustatis, lu- 
nula humerali antice abbreviata postice inflexa, cum linea marginali iuncta, hoc ramulo ad medium emittente, ver- 
sus guttam dorsalem tendente, lunulaque apicali tenui antice inflexa albis; subtus viridi-cyanea lateribus albo-pilosis, 
ano obscuro, trochanteribus, femorum apice, tibiis tarsisque plus minusve testaceis. Long. -34.
