famil}' Crucifera?, such as shepherd's purse and pepper grass, under 

 which the nymphs are frequently found in large numbers. 



All efforts to rear the insect or to determine its life history proved 

 futile, as appears to have been the case in the past, for no definite 

 observations seem to ha\e been made concerning its life history. 

 Professor Forbes" states that Professor Osborn has taken the eggs in 

 Amaranthus blossoms, but this would not necessarily indicate that to 

 be the usual place of oviposition. Undoubtedly the winter is passed 

 in the adult stage, and there is probabl}" more than one brood in a 

 season. The species is a difficult one for the entomologist to studj", 

 either from the economic or from the systematic standpoint. After 

 the examination of a large series taken in various localities in Texas 

 and on various plants, Mr. Heidemann considers all the specimens to 

 be of this species, but he states that the genus is so poorly known that 

 it is impossible to satisfactoril}' separate the species at present. 



The nymphs ma}' be readily combated b}^ spraying with kerosene 

 emulsion, but the adults are difficult to handle. On garden crops we 

 have found that bv beating along the infested plants with a small 

 screen covered with a stick}^ substance, such as is used for ''fly paper," 

 large numbers ma^' 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 historv would undoubtedly aid in devising means 

 for controlling the insect on field 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 Chitteur

Injury by this species was jiersonally inve8tigated at Herod, near Dawson, Ga., 

 May 27, 1904. Beetles were found upon about 15 acres of cotton, from 4 to 10 beetles 

 on each plant. The plants were about 4 inches high. The beetles feed for the most
