THE GRAPEVINE COLASPIS ON BEANS.—Throughout July Colaspis 
brunnea Fab. was found on the foliage of beans in the District and in 
neighboring portions of Maryland. At Kensington, Md., it was pres- 
ent in larger numbers on beans than the bean leaf-beetle, and the holes 
in the leaves there and in Washington were in the main probably the 
work of this Colaspis. 
This species, as its vernacular name sufficiently indicates, is better 
known as a depredator upon grape, but the beetles and larvie also infest 
the strawberry, whence it derives its other name of strawberry root- 
worm. The adult has also been observed to attack the leaves of clover 
and LeConte pear, and quite recently Mr. F. M. Webster has stated 
that it was reported to him to be eating the tops of potatoes and destroy- 
ing beans and corn (Bull. No. 2, n.s., Div. Ent., p. 90). The writer also 
has collected this species on potato. 
An immature larva very closely resembling the larva of this beetle 
was found at the roots of bean, but was unfortunately too much injured 
for positive identification. I have noticed a partiality of this beetle 
for the foliage of tick-trefoil (Desmodium [ Meibomia| spp.) but have failed 
to find the larve at the roots of this genus of plants. 
As the egg of this species has apparently not previously been 
observed a description is submitted. The eggs are probably deposited 
in much the same manner as are those of allied species, such as the 
grapevine Fidias. In confinement they were laid in masses of from thir- 
teen to considerably more and were deposited rather irregularly but 
many were placed side by side. 
The egg is elliptical, nearly two and a half times as long as wide, not 
perceptibly flattened at any point, just perceptibly narrower, and less 
rounded, usually, at one end than at the other, and stramineous in color. 
The surface is perfectly smooth without visible sculpture and moderately 
Shining. Length, 0.5-0.54™™".:; width, 0.21-0.23", 
This beetle has been collected in Maryland and Virginia in the vicin- 
ity of the District from June 24 to July 31. Itis abundant on the New 
Jersey tea plant (Ceanothus americanus), on flowers and leaves. 
THE HORSE-RADISH FLEA-BEETLE IN WISCONSIN.—In February 
Dr. EK. G. Love sent specimens of Phyllotreta armoracie Koch, the 
horse radish flea-beetle, with the statement that they were taken in 
July, 1896, at Okauchee, Wis., a little place on Oconomowae Lake, 
about 30 miles almost due west of Milwaukee. They were found abun- 
dantly on horse-radish. It will be remembered, perhaps, that the author 
in the article on this species published in Volume VII of Insect Life 
(p. 405), and in which Chicago, Il., and Guttenberg, Lowa, were given 
as American localities, surmised that it had ‘already invaded Wiscon- 
sin and Indiana,” and that it would soon spread to Missouri.and per- 
haps to southern Minnesota and Michigan. In other words, it will in
