family Cruciferae, such as shepherd's purse and pepper Lira--, under 
which the nymphs arc frequently found in large numbers. 
All efforts to rear the insect or to determine it- life history proved 
futile, as appears to have been the ease in the past, for no definite 
observations seem to have been made concerning it- life history. 
Professor Forbes states that Professor Osborn ha- taken the ecro- in 
Amaranthus blossoms, but this would not necessarily indicate that to 
be the usual place of oviposition. Undoubtedly the winter i- passed 
in the adult stage, and there is probably more than one brood in a 
season. The species is a difficult one for the entomologist to study, 
either from the economic or from the systematic standpoint. After 
the examination of a large series taken in various localities in Texa- 
and on various plants. Mr. Heidemann considers all the specimen- t<> 
be of this species, but he states that the genus is so poorly known that 
it is impossible to satisfactorily separate the species at present. 
The nymphs may be readily combated by spraying with kerosene 
emulsion, but the adults are difficult to handle. On garden crop- \\ r e 
have found that by beating along the infested plants with a small 
screen covered with a sticky substance, such as is used for "fly paper." 
large numbers may be caught. Tobacco water applied copiously on 
the soil around the plants is also of value in the garden. A better 
knowledge of the life history would undoubtedly aid in devising means 
for controlling the insect on Held crops, which fortunately, however, 
are not often attacked.

This weevil was frequently sent to us, being mistaken for the boll 
weevil. In several instances, however, it was stated that it was doing- 
noticeable damage to young cotton, as has 
already been reported by Doctor Chitten- 
den/' Subsequent to his report, in May. 
L904, serious injury was done by the species 
in Georgia. As it was impossible to investi-
