dial fascia is sometimes connected also with this line; finally, the under surface is blue and 
green, without any admixture of copper.

C. rubriventris Chevr. Col. Mex. 2nd cent. 
New Mexico, collected at Frontera, on the Rio Grande by J. D. Clark, Hsq., of the 
Mexican Boundary Commission: in every respect except colour, and in the form of the 
medial band of the elytra, which does not extend to the margin, it entirely agrees with C. 
Hentzii. 
52. C. rufiventris, atro-fusca, capite thoraceque seneo-variegatis, elytris cyanco-punctatis, punctis utrinque 
sex (seepe obsoletis) lunulaque apicali tenui albis, subtus ad latera albo-pilosa, antepectore cyaneo, postpectore 
pedibusque viridi-zeneis, abdomine toto rufo. Long. -4—-45.

Southern States, Maryland to Alabama, among the Alleghany Mountains. Only differs 
from the two preceding by the spots of the elytra being very small, and sometimes entirely 
wanting: the middle band is represented by two spots, the outer one being remote from 
the margin, and not larger than the inner one. 
58. C. cumatilis, viridi-cyanea, capite subtiliter granulato, utrinque striolato, thorace subcylindrico, sub- 
tiliter rugoso, ad latera parce piloso, elytris confertim haud profunde cyaneo-punctatis, foveisque versus sutu- 
ram serie impressis, ad apicem rotundatis serrulatis, spina suturali prominula, puncto humerali, fascia media inter- 
rupta oblique flexa marginem haud attingente, macula marginali pone medium, lunula apicali tenui, punctoque 
postico discoidali albis, (seepe obliteratis, hunula sola apicali relicta ;) subtus cyanea ad latera parce pilosa, abdomine

Shreveport, Louisiana, Mr. Guex: Creek Boundary, Dr. Woodhouse. Usually the mid- 
dle band and posterior marginal and discoidal spots are represented by extremely small 
white dots: the apical lunule appears to be always present, but is not inflexed.

GROUP XIX. 
A species, above of a shining black colour, almost destitute of metallic lustre. Eyes 
large and prominent; maxillary palpi piceous, but labial palpi pale at the base in both 
sexes. Front glabrous with a few striz each side; labrum large, rounded, hardly toothed. 
Thorax cylindrical, hardly rugous or granulate. Elytra slightly narrowed in front, very © 
faintly punctured, with a row of shallow foves: near the suture; apex broadly rounded 
hardly serrate; the markings are a very narrow apical lunule and one or two dots about
