AMERICAN COLEOPTEUA. 49 



New COLEOPTERA collected on the Survey for the extension of the Union 

 Pacific Railway, E. D. from Kansas to Fort Craig, New Mexico. 



BY JOHN T^. LE CONTE, M. D. 



During the summer and autumn of 1867 I had the opportunity, in 

 company with my friend Dr. S. Lewis, of being connected with the 

 surveying party under charge of Gen. W. W. Wright, for the exten- 

 sion of the raih'oad above mentioned. Our journey in part lay through 

 a region previously but little known, the valley of the Purgatory, and 

 the Raton Mountain, and as was to be expected, a moderate number of 

 new species of Coleoptera were found, several of which are very in- 

 teresting additions to our fauna. I have added in a few instances spe- 

 cies from neighboring regions which were prevfcusly in m}' collection. 



CICINDELA Linn. 

 C. citaarrona, nigra, subtusnitida, supra opaca,mandibularum basi labroqne 

 nlhis, hoc tridentato, fronte pilosa utrinque fortiter riigosa, thorace trapezoideo, 

 postice angustato, lateribus antice solum rotundatis, dorso confertim rugoso, 

 iin])ressionibus transversis profundis; elytris thorace fere duplo latioribus, 

 granulato-punctatis, margine apicali -baud serrato, signaturis albidis notatis, 

 viz: vitta submarginali pone humero et ante apicera. dilatato, fasciaque me- 

 dia obliqua nonunquam paulo curvata, vel obtuse angulata. Long. 14 — l.'« 

 mm. 



South of Raton Mountain ; six specimens collected by Dr. Lewis. 

 One specimen has the white markings of the elytra much more slen- 

 der and the marginal band is interrupted before and behind the mid- 

 dle, presenting the same form as in 0. (tnrocisconru.ns, except that the 

 medial band descends obliquely from the obtuse angle, instead of being- 

 curved ; but on comparison it differs not only by the color and mark- 

 ings, but by the thorax being broader in front, less rounded on the 

 sides, convex on the disc, and also by the more stout form, and by the 

 apical margin of the elytra being absolutely free from serration. 



The palpi are entirely black in both sexes; this character with the 

 smooth apical margin of the elytra places this species in group vr. of 

 my revision of Cicindelae, Tntna. Am. Phi/. Soc. xi, 36, near C jfui- 

 jiurc'ti with which it agrees in form and sculpture. It is perhaps the 

 American analogue of the Russian O. diufdux. which is placed by 

 Chaudoir in a different group.
