62 REVISION OF THE CICINDELZ OF THE UNITED STATES. 
C. cwrulea || Herbst, Kafer, 10, 182, tab. 172, fig. 4. (C. Kunzii Gistl.) as stated by Hrichson, is also a 
variety of C. germanica. 
C. venosa Kollar, Ann. Wien. Mus. 1, 330, as I am informed by Dr. Schaum is C. nitida Dej. 
AP PE NSD eX: 
10—11. C. viatica, cyaneo-viridis, fronte utrinque striata medio punctata ct pilosa, capite thoraceque subti- 
lius minus dense rugosis, hoc convexo lateribus rotundato, postice paulo angustato, elytris haud profunde punctatis, 
punctis postice fere obliteratis, puncto humerali strigaque brevi transversa ad medium albis, ad apicem subtiliter 
serrulatis spina suturali parva: subtus cyanea parce albo-pilosa, labro (feminz) albo, antice obsolete tridentato.

Chevr. Col. Mex. 2nd cent. no. 180. 
Sonora, Mr. Arthur Schott; one specimen. While these sheets were passing through 
the press, a valuable collection made by Mr. Schott during his concluding field labours on 
the Boundary between the United States and Mexico has been submitted to me by the 
kindness of the Commissioner, Major W. H. Emory: and in it, with many most beautiful 
species of other genera, occurred the present interesting addition to our fauna. 
This species resembles in form and colour C. sexguttata, but differs from it by the 
less densely rugose thorax, the less deeply punctured elytra, and the pilose front. It 
seems in fact to be most nearly related to the sexguttata group, tending towards the pre- 
ceding group, in C. rugifrons, from which it is obviously distinguished by the serrate elytra, 
and less robust form; from both groups it differs by the very slightly marked teeth of the 
labrum. | 
This species should therefore form a new group immediately before V. characterized as 
follows: 
Thorax convex, sparsely rugous; front striate, pilose; elytra finely serrulate, not deep- 
ly punctured, markings very imperfect. 
GROUP VI. 
On renewed examination, with a very powerful lens, I find that the tips of the elytra 
of C. splendida and limbalis are not absolutely free from serratures. In the former espe- 
cially the serration may be perceived in most specimens, but individuals of both species occur 
in which almost every trace of serration has vanished. In the groups 1.—1v., even with 
the powerful lens, the edge appears perfectly smooth. 
27—28.C. californica. By the kind attention of Mr. Ménétriés, I have 
received, since the printing of the preceding pages, a diagram of an elytron of his 
species, which I have here reproduced in a wood cut. The markings are quite 
distinct from any known to me; Mr. Ménétriés informs me in his letter that the 
labrum has only asingle tooth. The species must be placed either in group Vim. 
or IX.
