By descrip- tion, the present species is close to Scudder's C. luti but has relatively a much shorter prothorax. The figure of C. luti represents the abdo- men as having six segments. Colaspis proserpina, sp. nov. Plate 11, fig. 2. Form moderately elongate. Head without definable sculpture, eye elliptical, antenna poorly preserved but evidently long, about half the length of the body. Prothorax simply roughened, the separate punctures not distinguishable. Meso- and metasternum, their side- pieces and abdomen nearly smooth. Elytron roughened as if sculp- tured with partly obliterated irregular punctures after the manner of the recent C. chrysis, though less deeply. Legs too poorly preserved for description. Length, mm. Described from one specimen with counterpart. Type.— No. 2,624, 2,625 M. C. Z. Florissant, Col. (No. 9,006 and 9,103 S. H. Scudder Coll.). The generic reference is open to doubt. The insect seems to belong to the Eumolpini and near Colaspis but the sculpture is not matched in my series of recent forms. Most of the upper surface seems to be rough as in C. chrysis while the smooth side-pieces of the meso- and metasternum are like Rhabdopterus. True generic characters are lacking. It differs from the other Florissant species described as Colas- pis in the combination of size and sculpture. Chrysomela vesperalis Scudder. The specimen with counterpart, No. 2,627, 2,628 M. C. Z. (No. 11,264 and 13,649 S. H. Scudder Coll.), referred here, is shown in side view. It has altogether the form of Chrysomela and answers the de- tails of the original description. The elytral punctuation in the present specimen is fine, a point not specified by Scudder though natu- rally inferable from his Please n
