was of a greenish tinge, while the other was decidedly pinkish above 
and greenish below. Many pods were found that had been perforated 
and the beans excavated, but no other larve were seen. The larvee 
are very sluggish and not easily disturbed. The greenish one pupated 
July 16, and the adult butterfly emerged July 29. Two other larvie 
were found feeding on beans July 28, in the same plot from which the 
others had been taken. Both were pale green and apparently full- 
grown, being five-eighths of an inch in length. From one of these a 
number of parasitic grubs emerged July 31. Small snow-white cocoons 
were spun to the side of the cage, almost completely embedding the 
larva. The parasites emerged August 7. 
In an illustrated article in Insect Life (Vol. VII, pp. 354, 355) Dr. 
Howard gives a résumé of what is known of this beautiful little 
butterfly. 
Referring to injury to beans, Dr. Howard says that the Department 
received a larva of this insect from a correspondent in New Jersey in 
August, 1886, who wrote that it was feeding upon lima beans. It is 
stated also that Mr. Coquillett and Mr. Pergande had made similar 
observations, the former having found the larva feeding on beans at 
Los Angeles, Cal., September 5, 1889, and the latter observed it on 
beans near Washington, D. C., July 6 and October 18, 1892. 
Dr. Howard is of the opinion that this insect is not likely to become 
a serious enemy to the bean crop, but calls attention to the fact that in 
Harris’s time some farmers are said to have been obliged to abandon 
hop cultivation on account of the work of these larve. 
Cerotoma trifurcata.—This insect, better known, perhaps, as the 
bean-leaf beetle, C. caminea, was observed by me May 19, 1897, in a 
patch of wax and lima beans near the station. My attention was 
attracted to the ragged appearance of the leaves, and upon examina- 
tion I found this insect in great abundance on the plants. The wax 
were more severely injured than the lima beans, nothing but the midrib 
aud the larger veins being left on some leaves. The insect is easily dis- 
turbed, and drops quickly to the ground and hides when approached. 
The attack in this patch was local, as no beetles were found in other 
bean patches in the vicinity. The garden patch where the outbreak 
occurred was surrounded last fall by cowpeas, and it seems quite pos- 
sible that the beetles bred there in considerable numbers, appearing 
this spring and concentrating upon the beans near by. Beetles, pre- 
sumably of the second brood, have been common on plants in the gar- 
den since July 16. The beetles vary greatly in markings and color. 
Crambus caliginosellus.—This insect has been very destructive to 
young corn this seasen in Prince George, Cecil, Kent, Queen Anne, 
and Dorchester counties. July 20 I examined a large cornfield, be- 
longing to Mr. F. H. Eldridge, near Cecilton, Cecil County, and found 
that about 25 acres had been completely ruined by this pest, even 
after the fourth planting. The young corn was perforated and eaten
