REVISION OF THE CICINDELZ OF THE UNITED STATES. 4] 
GROUP VIII. 
Contains several species of a not slender form, with the thorax subquadrate and more 
flattened in the females than the males: the elytra are strongly punctured with inter- 
mixed granules, they are rounded and finely serrate at tip; in the females they are more 
or less dilated on the sides; the spots are normal, sometimes interrupted, sometimes con- 
nected on the margin, the medial band is perpendicularly bent. The head and thorax 
are finely rugous and granulate, the front is finely striate near the eyes, and is pilose in 
our native species; the labrum is moderately short, the middle tooth being acute and pro- 
minent, while the others are indistinct, and frequently wanting. The labial palpi at 
least of the male are pale at base. Sides of the thorax and body beneath hairy. 
The species may be divided into three principal forms: 
1. Lunules interrupted, middle band not dilated on the margin. CC. oregona and guttifera. 
2. Middle band dilated on the margin, humeral lunule curved, sometimes interrupted. C. 12-guttata and balti- 
morensis. 
3. Middle band dilated on the margin, humeral lunule perpendicularly bent. C. hirticollis. 
22. C. oregona, fusco-zenea, vel cyanea, fronte parce pilosa, utrinque subtiliter striata, thorace latitudine bre- 
viore, subquadrato, postice vix angustato, elytris pone humeros obtusos sensim latioribus, postice fortiter serratis, 
spina suturali prominula, punctatis granulatis, lunulis late interruptis, fascia media rectangulariter refracta ad mar- 
ginem haud latiore albis; subtus cyaneo-zenea, pleuris albo-pilosis; labro albo unidentato. Long. -4—-55. 
Mas palpis labialibus articulo penultimo pallido. Femina elytris magis dilatatis, palpis concoloribus nigris. 
C. duodecimguttata { Ménétriés, Bull. Soc. Imp. St. Petersb. 2, 52; et auctorum aliorum, (sine descriptione.) 
Oregon Territory and Northern California, as far as San Francisco. Of the same form 
as C. 12-guttata, but having the elytra of the female more dilated, and the apical serra- 
tures and the sutural spine much more distinct. 
The white spots of the elytra are large and conspicuous, but show no tendency to unite 
along the margin; they are thus placed: a humeral spot; a middle fascia bent at a right 
angle, and then curved towards the suture, terminating in a round spot: an apical spot, 
and two round submarginal spots, one midway between the humerus and middle band, 
the other between the band and the tip, but rather nearer the latter. The specimens 
from Oregon were collected by Dr. J. G. Cooper, they are all blue, or of a dull olive green 
above: the specimen found by me at Benicia is above of a fuscous bronze colour varied 
with coppery and brassy, as in our common C. baltimorensis.

Here seems the proper place to refer some fragments of a specimen collected by Dr. 
Cooper at Prairie Pass, Oregon. The head is not in the least respect different from that 
of the preceding, but the elytra are less dilated and less strongly serrate: the surface 
is more strongly punctured, and the middle band does not arise perpendicularly (as in all
