The Chinch Bog in Texas. 



But little has been written concerning the common chinch 

 bnq- (Blissus lencopterus) in the Gulf States. In endeavoring 

 to devise means for its control in Texas several notes of gen- 

 eral interest were made. 



The region affected by the chinch bug in Texas is largely 

 coextensive with the grain belt, but injury occurs south into the 

 central part of the State as far as Brazos County, about 125 

 miles north of the Gulf. South of this we received no com- 

 plaint of damage. The adult bugs hibernate over winter in 

 fields of small grain, in the stalks and stubble of corn, under 

 bark of logs, and seemingly in any sheltered situation. We 

 have found them numerous in the hollows made in the stem of 

 the bull nettle (Solatium rostratum) by the little beetle Tricho- 

 baris texana. They emerge in March or April according to 

 the season. In 1903 they were first noticed in north Texas 

 the second week in April. At College Station they were 

 numerous on the 20th, but oviposition did not take place until 

 about May I. In 1904, the season being unusually early, 

 straggling specimens were observed at College Station March 

 7th. On March 30th they were common on volunteer sorghum, 

 though none on corn, and first copulation was observed. In 

 1903 the first young nymphs were observed May 8. On May 

 21 the first instar was still most abundant, though a few in the 

 second instar were found. June 4 some had reached the
