was described by the writer in Bulletin No. 19 of the present series 
(p. 75). It is perfectly snow-white with just a perceptible luster when 
laid, but becomes grayer when near the hatching time. The larva and 
pupa have never been described, to the writer’s knowledge. 
DISTRIBUTION. 
The list of localities in which Zigyrus gibbosus has heen observed. 
and by which it is represented in most cases in the National Museum, 
includes territory from Long Island to California and Oregon, as well 
as the Gulf States. It indicates a very wide distribution, but so far as 
we know at present the species does not occur in the Northern States 
in the Transition or even in the more northern portions of the Upper 
Austral life zones. For example, although it is extremely abundant 
about the city of New York, it does not occur in the central portion of 
the State. A list of known localities follows: 
New York, Staten Island, Long Island, N. Y.; in New Jersey at Trevose, Brigan- 
tine, and Highlands, and ‘‘throughout the State, but much more common along the 
shore at light’? (Smith); Pennsylvania; Maryland; Cobb’s Island, Pennington Gap, 
Fortress Monroe, and Virginia Beach, Va.; District of Columbia; Keokuk, Iowa; 
Thomson, I1l.; Purdue and Chesterton, Ind.; Moody, Ark.; Topeka, Riley County, 
Onaga, and Atchison, Kans.; St. James and Glencoe, Nebr.; Capron and Crescent 
City, Fla.; Craig, Miss.; San Diego, Plainview, Rock Hill, and Gainesville, Tex.; Salt 
Lake, Utah; Las Cruces, Albuquerque, Mesilla Valley, and Water Canon, N. Mex.; 
Yuma and Wilcox, Ariz.; Bayou La Fourche, Mer Rouge, and Ville Platte, La.; 
Grand Rapids, Wis.; Pueblo, Colo.; Los Angeles, Kern County, and southern Cali- 
fornia; Hood River, and Dalles, Oreg. 
RECENT INJURIOUS AND OTHER UNRECORDED OCCURRENCES. 
April 21, 1900, Mr. René L. Derouen, Ville Platte, La., sent speci- 
mens of this insect with the report that the species was concerned in 
the destruction of the corn crop of that vicinity. The beetles were 
described as cutting the corn just above the roots. The previous 
year’s crop was lost through its depredations, and fear was expressed 
that the country might suffer very much indeed through the ravages 
of this pest. Mr. James Lambeth, Craig, Miss., sent specimens, with 
the information that many of these insects were to be found in a corn- 
field about an inch deep in the ground. 
During 1901 we received in June specimens of the beetle, with 
information from Prof. W. G. Johnson, associate editor American 
Agriculturist, that this species was found injuring the roots of sun- 
flower and sweet potato at Thomson, Carroll County, Ill. October 10 
we received specimens of beetles eating the roots of celery, carrots, 
and parsnips, and sent by Mr. F. J. Dickinson, Chesterton, Ind. He 
stated that the carrot crop appeared to be in good condition, judging 
from the tops, but when the plants were pulled it was seen that the 
roots were full of little holes. The beetles appeared to work entirely
