SOME INSECTS INJURIOUS TO TRUCK CROPS. 
THE LIMA-BEAN POD-BORER.

INJURIOUS OCCURRENCE. 
In looking over some old material and notes in the Bureau of 
Entomology and National Museum, some larvae closely resembling 
the Lima-bean vine-borer (Monoptilota nubilella Hulst) were discov- 
ered, accompanied by a note by Mr. Albert Koebele to the effect 
that they were found on Lima beans at Rattlesnake Bridge, Eldorado 
County, Cal., July 21, 1885. The beans in that vicinity were much 
infested by larvae of this species. The seed beans had been received 
from Ohio the previous spring, but this evidently had -no bearing on 
the origin of the insect, although the larvae injured the growing 
seeds. 
More recently, in 1908, the same species was discovered by Mr. 
H. O. Marsh at Santa Ana and Garden Grove, Cal., in September 
and October, infesting Lima-bean pods. At this time it was abun- 
dant in Santa Ana, in one garden nearly every pod containing a 
larva; at Garden Grove the species had ruined fully 40 per cent of 
a good-sized patch of late beans. Another lot was received from 
Anaheim, Cal., October 22. The larvae were common at this time 
also but not as injurious as in the other localities. The adults 
began issuing January 9, 1909, and continued coming out until Feb- 
ruary 25. 
Later the same collector found this species at work at Compton 
and Watts, Cal., in November. During the latter half of November 
the larvae were scarce, practically all having disappeared with the 
exception of a few belated individuals here and there. 
DESCRIPTION AND DISTRIBUTION. 
The moth has a wing expanse of a little less than an inch; the 
head is armed with three long, conspicuous labial palpi, showing its 
relation to the snout-moths. The ground color is gray, interspersed
