Eagle Pass, Rio Grande, Texas: collected by Mr. Schott of the Boundary Commission. 
Nearly related to the preceding, but the thorax is more convex, and more rounded on the 
sides, and the posterior angles fall into the base instead of beg prominent. The middle 
band of the elytra is about as sinuous as in the well known C. limbalis, (a race of C. 
splendida) but is narrower and frequently obsolete. 
GROUP II. 
The group contains one species of a somewhat flattened form, and dull brownish colour, 
above almost without metallic reflections. The labrum is large, prominent in the mid- 
dle, with three distinct teeth; the outer angles are very obtuse. The palpi of both sexes 
are entirely black. The front is flattened, finely wrinkled, and striate towards the eyes, 
entirely bald; the surface of the head and thorax is distinctly granulate. ‘Thorax flat- 
tened, trapezoidal. Elytra not serrate at tips, which are separately acutely rounded, 
without any sutural spine: the punctures are large and shallow, the markings marginal, 
frequently wanting. Body beneath glabrous. yes rather small, but prominent. 
4, C.un ipu netata, seneo-fusca, opaca, sericea, labro albo tridentato, fronte tota striolata, thorace trapezoideo 
planiusculo, latitudine haud breviore, confertim rugoso ad latera vix rotundata parce albo-piloso; elytris pone hu- 
meros latioribus, distinctius marginatis planiusculis, equaliter punctatis foveisque sparsis preecipue versus suturam 
notatis, punctis omnibus cyaneis, apice singulatim rotundatis, macula marginali intus obsolete prolongata ad me- 
dium alba; subtus nigro-purpurea glabra. Long -68—-68. :

Pennsylvania, Missouri, Georgia; found in paths in shady, hilly woods in May or June, 
according to the latitude of the locality: the merit of discovering a locality in the imme- 
diate neighbourhood of Philadelphia is due to Mr. Schafhirt. Varieties are mentioned 
by Mr. Say in which there is a supplemental spot half way between the medial one and
