ARTHROCNODAX CAROLINA N. SP. 



By E. P. Felt, Albany, N. Y. 



The species described below is allied to A. apiphila Felt from which 

 it is easily separated by the lighter circumfili and the longer stems 

 of the antennal segments in the male. It is easily separated from 

 A. occidentalis Felt, a species recorded as preying upon red spider in 

 California, by the shorter stems of the antennal segments in the male 

 and by the rounded -ventral plate. Mr. E. A. MacGregor, who reared 

 this species in both 1912 and 1913 from red spider on cotton, is of the 

 opinion that it is the most important natural agent in controlling this 

 pest. 



Male. Length .75 mm. Antennae about as long as the body, sparsely haired, 

 light brown; 14 segments, the fifth having the two parts of the stems with a length 

 three-fourths and one and three-fourths times their diameters, respectively. The
