Lima beans — something- that it was not observed to do in previous 
seasons. 
October 8, he made .examination of different plants growing in his 
own garden and reported that at least 50 per cent of the galls examined 
showed that the occupants had escaped. From observations made at 
this time he concludes that this vine borer is capable of doing severe 
damage, the part of the stem above the galls seldom producing beans, 
and in some cases dying. Injury, however, is not readily apparent 
owing to the fact that from 4 to 6 plants often grow on one pole and 
injured portions are usually concealed by the numerous leaves. In 
one instance no less than IT galls were counted on a single plant, while 
the other plants in the same hill were scarcely affected. In another 
instance galls were observed at the roots of the plants on a level with 
the soil, the gallery extending an inch below the surface. 
At Cabin John, Md., where this species occurred in 1898 and 1899, 
it reappeared, but in much diminished numbers. 
After the publication of the writer's article, previously cited, Dr. 
Hopkins's note entitled U A Lima bean borer" was remembered, too 
late, however, for insertion in the bulletin mentioned. This note 
appeared in Volume VII of Insect Life (p. 146.) As the publication 
mentioned is not available to everyone, his note may be repeated here: 
September 8, a Lepidopterous larva was found causing considerable damage to Lima- 
bean vines in Wood County, W. Va. The larva was about one inch long, the body 
uniform purple above and light blue beneath. It occupied about two inches of the 
vine, causing a swelling or kind of gall, in this respect resembling the habits of the 
common stalk borer (Gortyna nitela). When more than one larva occurred in a plant 
it died from the injury. I also failed to rear the adult of this insect. 
Dr. Hopkins's as well as the writer feels little hesitancy in stating 
that this is the same species, Monoptilota mibilella Hulst. 
A new natural enemy of this insect was observed by Mr. Pratt at 
St. Elmo, Va. , the larva of a species of soldier beetle, either Chau- 
liognathus pennsylvanicus or Oh, marg hiatus. This larva was detected 
in the act of devouring a vine-borer larva, and several dead larvae of 
the moth and of the soldier beetle were found in the galls. 
Diabrotica atripennis Sa} r . — July 10, 1899, the adults of this species 
were observed by Mr. Pratt attacking the blossoms of Lima beans at 
Travilah, Md. Specimens brought to this office continued feeding on 
bean blossoms in confinement. This is the first observation of the 
food habits of this species of which the writer has knowledge. The 
larval habits are unknown, but larvae doubtless feed about the roots 
of some wild leguminous plant in the same manner as Diabrotica vittata 
feeds upon cucurbits and 12-punctata at the roots of cereals.
