 suhdeleta, Ent. Mo. Mag. 1885, 224. — The case of Abraxas, in 

 which a many-spotted moth occasionally appears almost or quite 

 spotless, is exactly reversed in the American Ilyphantria cunca, 

 Drury. Near Washington the type of this insect is spotless 

 white, but further south a variety {pimctatissima, Smith), is found, 

 in which the wings are profusely spotted with black, while every 

 gradation between these two extremes occurs. (For figures showing 

 variation, see U. S. Dept. Agric, Entom. Div. Bulletin, 10, 1887). 



p. Unusual development of light markings. 

 Papilio asterias calverleyi, Grote, " probably caused by the 

 action of cold on the pupa soon after pupating " (G. H. French). 

 Graptaj -album aureomarginata. The yellow border to the wings 

 without marks, and bright golden yellow (Maynard). Vanessa 

 antiopa hygicea, Hdrch. ( = lintnerii, Fitch). According to May- 

 nard, this variety is said to occur in America in the proportion of 

 about 1 to 500, typical = ; he thinks it is perhaps due to reversion. 

 Dr. Lang states that this variety has been taken in Britain. 

 ZygcenaJllipendulcB cytisi, Hb. Vanessa cardui, var. from Grahams- 

 town, Proc. S. Lond. Ent. Soc. 1886, 60 (J. J. Weir).— These, of 

 course, are similar in nature to the last, but their cause is very 

 obscure, and probably not the same in every case. I cannot agree 

 with Prof. French that P. asterias calverleyi was caused by cold, 

 especially as he says " soon after pupating," at v^^hich period the 

 wing-pigments would not have begun to be formed. Besides, 

 this aberration has been taken in Florida, where severe cold does 



not occur.

DESCRIPTIONS OF TWO NEW SPECIES OF THE 



COLEOPTEROUS FAMILY CETONIID^E. 



By Oi.ivKR E. Janson, F.E.S. 



CUnteria rvfipennis, n. sp. 

 Head coppery green, shining, coarsely punctured, the punctures con- 

 fluent at the sides and apex, a fine smooth median hue, apex of the clypeus 

 rounded, a httle reflexed, and with a small central uoicli. Thorax dull 

 coppery olive, a broad angular band on each side, and a small round spot 

 on the basal lobe pale ochreous yellow, the disk finely and very sparsely 

 punctured. Elytra dull red with five pale ochreous yellow spots on each ; 

 the first in the centre about one-fourth from the base ; the second nearer 

 the sutui-e, about midway between the base and apex; the third close to 

 the outer margin just beyond the middle ; the fourth near the outer apical 

 au«le ; the fifth between the apical callosity and the suture ; the third spot 

 is transverse and sinuous, the others are sub-orbicular ; the disk with some
