132 Mr. SezNcz's Monograph of the Genus Choleva. 
It may be necessary to add a few words relative to the species 
included under this genus by other authors, but not here described 
or referred to. Of the five enumerated by Frölich in his paper 
in the Naturforscher, the three first are true Choleve : the two last, 
Luperus pallidus, and sanguinicollis, with filiform antenne, seem 
|. to belong to some other genus. The former is probably Cyphon 
pallidus of Fabricius, Crioceris pallida of Marsham. Of the six 
species of Catops described by Fabricius in the Systema Eleuthe- 
ratorum, C. sericeus, agilis, and Morio, are doubtless true Choleve, 
and probably synonymous with species here described ; though 
from the brevity of the descriptions it is not possible to be cer- 
tain on this head. C. vittatus was before a Tritoma; and being 
described from Dr. Hunter's cabinet, which Fabricius could not 
refer to, its claim to be deemed a Catops is very doubtful; which 
may be said also of C. flavipes, a Helops of the Ent. Syst. 'This last 
is an American species with crenate strie,—a character found in 
none else of the genus, and is, according to Illiger, a true Cistela. 
The remaining species, C. rufescens (Tritoma minuta Ent. Syst.) 
is very obscure. It is synonymed with Chrysomela minuta Linn., 
which is beyond all question one of the laminated Dytici, (D. ru- 
ficollis Ent. Brit.) and in the Ent. Syst. Fabricius gives as its 
habitat “ In aquosis.” "This he has changed in the Syst. Eleuth. 
for “sub corticibus arborum" but he still retains Linné's sy- 
nonym, adding to it, surely very erroneously, Ptomaphagus ru- 
fescens of Mliger. The description is very short and inexpressive, 
so that it is impossible to guess what is meant by this species ; 
and no cabinet is referred to. 
It is somewhat remarkable that I have never observed a single 
species of this genus in any of the rich foreign cabinets of the 
metropolis. : |
