Mispa rosea, Weber, Obs. Ent. 1801, p. 66. 
Anguste oblongus, pallide flavo-fulvus ; pectore, oculis elytrorumque maculis nigro-piceis ; antennis basi piceo- 
tinctis ; thorace subcylindrico, disco utrinque leviter excavato, rude et fortiter punctato ; angulo antico 
dente obliquo obtuso armato ; limbo (basi excepta) vittisque discoidalibus duabus (his sepe obsoletis) piceis ; 
elytris parallelis, apicem versus vix ampliatis, serrulatis, apice obtusis, angulo postico distincto obtuso ; 
utrisque octo- basi extrema nono-seriato-punctatis, striis inter costas 1™ et 2" ad apicem minus regu- 
lariter dispositis; interspatiis secundo, quarto et sexto, nec non sutura, costatis, costis ante apicem 
abbreviatis, tertia apice cristata, externis duabus apice connexis.

Vertex smooth, impunctate, impressed with a longitudinal groove; interocular 
space moderately but distinctly produced, obtuse. Antenne rather longer than the 
head and thorax ; joints cylindrical, the five outer ones distinctly thickened. ‘Thorax 
broader than long ; sides obsoletely angulate, nearly straight and parallel from the base 
to the middle, thence slightly converging to the apex, anterior angle armed with a 
strong, oblique, obtuse tooth ; subcylindrical, faintly excavated on either aide the medial 
line, strongly and coarsely punctured. Elytra oblong, very slightly dilated posteriorly ; 
hinder angle obtuse, very slightly produced in the male, rather less distinctly so in the 
female; apices conjointly, obtusely rounded in either sex; sides and apex rather 
coarsely serrulate ; each elytron with eight, at its extreme base with nine, rows of 
punctures, the puncturing of the rows between the first and second coste confused 
towards the apex (in some specimens there are traces on the hinder disc of an additional 
row); second, fourth, and sixth interspaces, together with the suture, costate; the 
discoidal cost terminate before reaching the hinder margin of the elytron; the third 
or outer costa is cristate at its termination, and is connected with the raised apex of the 
second or intermediate one by a short curved ridge; a transverse raised line (sometimes 
ill-defined) also connects the apices of the first and third coste. 
Contrary to the opinion of American entomologists, I cannot help considering 
C. roseus, Weber, and C. inequalis of the same author, usually united under the former 
name, to be distinct. C. roseus is separated by the pale antenne, and by the obtuse 
apices and the more or less defined hinder angle of the elytra; distinct and apparently 
constant differences also exist in the elytral coste. In C. inequalis the apices of the 
elytra are regularly rounded, the posterior angles being obsolete and the apices of all the 
coste free; the third or outer costa is not more strongly raised posteriorly, as is the 
case in the present species. Both insects are equally variable in coloration. 
I do not (with one exception) give any synonymy, as I have not had an opportunity
