of the elytra, and from C. tortuosa by the distinctly granulate thorax. Should it be ne- 
cessary to unite the preceding with this species, let C. serpens be the name retained.

San Diego, California, on the sea-shore. Baron Chaudoir, to whom I sent specimens of 
this species, regards it as merely a variety of C. tortuosa, which varies somewhat in the 
width of the elytral markings. The great difference in the punctuation of the elytra, a 
character found in all the specimens collected, induces me to separate it from C. serpens, 
while the distinct granulation of the thorax prevents it being joined to the next species.

Georgia and Louisiana, on the mud of rice fields. Besides the finer and almost indis- 
tinct granulation of the thorax, the punctures of the elytra are smaller and less deep than 
in the other species of the group. The white markings are very narrow and frequently 
interrupted, 
The ‘C. trifasciata Fabr.’ figured by Olivier and Herbst, does not at all resemble this 
species, nor, as observed by Dr. Harris in a letter to me, can the original words of the 
Fabrician description ‘striga secunda flexuosa’ be applied to it, since the same expression 
is used in the descriptions of C. flexuosa and lurida, in which the middle band is rectangu- 
larly bent, as in our C. vulgaris and many others. Moreover, the remark ‘Habitat Italia 
paullo minor,’ (Ent. Syst. 1, 177) must be allowed to have some weight in the determi- 
nation, and if the name be not applied to some West Indian species resembling one found 
in Europe, it should be entirely dropped, as tending to confusion. 
GROUP XV. 
A species of normal form; the head and thorax are very finely granulate, the former 
is glabrous and finely striate near the eyes; the latter is subcylindrical, convex and slightly 
rounded on the sides, which are sparingly pilose. Labrum one-toothed, labial palpi pale 
with the last joint dark; eyes large. LElytra finely serrate, with the tip rounded in both 
sexes, with a small sutural spine; densely punctured, with a row of unusually large fovese 
near the suture: markings interrupted; the medial band from the position of the spots,
