ONCOMETOPIA DNDATA. D i 
found, though the eggs were not observed. Our latest record for the 
adults in the field is October 10, L902, at Courtney, Tex., but it is 
quite possible that they may occur later. It seems clear that there 
are two generations of this species, and there is a derided probability 
of at least a partial third generation. 
The species is entirely harmless to cotton and is much more common 
on trees. It was reported as quite injurious to grapes at San Marcos, 
Tex.. May L0, 1886,° and at Greensboro, Ala., dune 25, L890, J and we 
have recently had similar reports. Lugger has also given a short 
description of the species and its work on grape. c It was responsible 
for the so-called 4 * weeping willow." which attracted public attention in 
north Texas in L889, d the '* weeping" being due to the remarkable excre- 
tion of this species, which very frequently is ejected to a considerable 
distance. This has been observed and reported to us by Mr. J. ('. 
Melcher, of O'Quinn, Tex. It has also been recorded in Insect Life 
as occurring on orange trees in Florida and on cabbage and okra in 
Mississippi. On August 8, 1896, the records of the Bureau of Ento- 
mology state that specimens were received from Joseph Husband, 
Leanderville, 111. He wrote that they infested apple, pear, and plum 
trees, and he had counted Id specimens on a young shoot 18 inches 
long. 
Dr. F. H. Chittenden states that the species is abundant in the Dis- 
trict of Columbia, and prefers for food the half-woody stems of volun- 
teer parsnips growing in shack 1 . The nymphs and adults are found 
particularly on elder. The species has been previously noted on cot- 
ton by Riley, Mally, and others, but no injury was reported. We 
must therefor* 1 conclude that, although occasionally injurious to 
grapes, the specie's is practically harmless to cotton. 
DESCRIPTION OF NYMPH, BY E. I). BALL. 
Head of general iorm of adult, less inclined ami slightly more inflated, almost 
semicircular before the eyes ami evenly rounding on to front. Body stout, about as 
wide as head, with abdomen tapering to a blunt apex. Color pale straw, marked 
with irregular pale fuscous lines and spots. Vertex with a fairly definite band con- 
necting the antennae, ami another between the eyes, usually interrupted in the mid- 
dle and connected by longitudinal stripes, dividing the disk of the vertex into irregu- 
lar oval compartments. A median basal pair of compartments contain two very 
definite dark spots. Anterior margin of vertex and front with three longitudinal 
stripes, the median one narrow and definite, the lateral ones broad and irregular 
above and narrowing down to a line below, where they curve in and unite with the 
median one. All three stripes interrupted by a narrow light line apparently sepa- 
rating vertex ami front. Pronotal and abdominal segments very irregularly marked 
with stripes ami dots. Legs pale.
