LEPTOGLOSSUS PHYLLOPUS L. 89 
1 specimen to every 10 plants. Prof. Wilmon Newell, secretary of 
the State Crop Pest Commission of Louisiana, and his assistants, 
while inspecting cotton fields for the Mexican cotton boll weevil 
in Rapides Parish, La., in September, 1905, found this species of 
leaf-footed plant-bug very abundant. The following quotation 
from Professor NewelPs notes, which he has kindly permitted to 
be used in this bulletin, illustrates the degree of importance these 
insects may attain in consideration of the individual destructiveness 
of plant-bugs, as shown in the studies of the conchuela. 
On September 7, in western Rapides Parish, adults of this species were found in 
abundance in cotton fields, usually resting or feeding on green bolls. In two or three 
fields near Forest Hill, these insects were so abundant as to average at least 2 adults 
to each stalk of cotton. Their damage in the aggregate must be considerable. Hemip- 
terous nymphs found on the bolls appeared to be of this species. Between September 
1 and 10 these bugs were found in greater or less abundance in every cotton field 
inspected in Rapides Parish. 
The author considers the species of plant-bug here discussed fully 
the equal of the conchuela in individual destructive capabilities. 
The data given in Table XXVI (p. 57) show that in one cotton field 
damage by the conchuela amounted to about 50 per cent when the 
bugs were about one-fourth as numerous as were the leaf-footed bugs 
in the 3 fields near Forest Hill, La., referred to by Professor Newell. 
On September 9, 1905, a female was taken in coitu and brought 
to the laboratory. It was supplied with fresh cotton bolls daily, 
but produced no eggs and died on October 28, the forty-ninth day 
of its confinement in the breeding cage. Upon dissection only 1 egg 
was found; this was of mature size and color, closely resembling in 
size, structure, and color the eggs of L. oppositus, described and 
figured by Dr. Chittenden. H. G. Hubbard a has stated that the 
normal food plant of this bug in the South is a large thistle. Mr 
F. C. Pratt observed adults in considerable numbers on dockweed 
(Rumex sp.) near San Antonio, Tex., on April 19, 1906, feeding and 
copulating, and on thistles near Baton Rouge, La., on April 22, 1906. 
Professor Newell found on May 19, 1905, in Sabine Parish, La., 
adults of L. plujUopus in abundance upon steins and seed-pods of 
"bear grass" {Yucca filamentosa) , a common weed in the western 
part of that State and generally found in greater or Less abundance 
in and around all cotton fields. In many eases the adults occurred 
upon the "bear grass" so abundantly that the stems and seed-pods 
were literally covered with them, and in several eases two or three 
dozen specimens were collected from the stems and seed-pods of a 
single plant. The insects could not be found on any other plant and 
seemed to depend entirely upon the "hear grass" for their subsistence 
at that season of the year.
