(quoting Strecker) is a repetition of only the anterior part 

 of the left primary wing. 



It would be well to record abnormal wing formations since 

 Bateson tells us, "In some cases the extra wing is a close copy 

 of a normal structure ; in others it seems to be more or less 

 deformed. No genuine case of an extra wing present on 

 both sides of the body is known to me." 



The upper illustration showing the ocellar marking on 

 the left fore-wing of Saiuia calif ornica is of an insect 

 which came from Sonoma County, California. This male 

 emerged on May 30, 1912, and was normal in every respect 

 excepting the "eye-spot'' in the left primary. This spot is a 

 hole in the insect's wing, the periphery of this hole being 

 white, edged off with a small band of brown. It was at first 

 thought that the insect had met with an accident, but since 

 the color was displaced and the edges around the hole were 

 not broken but smoothly finished off, we concluded it must 

 have acquired this condition before leaving the cocoon. Bate- 

 son, who goes into details concerning the eye-spots in Lepi- 

 doptera, mentions no case in any of his citations showing a 

 similar condition of wing formation.

 1. The Effects of the Partial Amputation of the Antennae (Lep.). 



Several times in June, 1902 and 1903, I removed most of 

 the antennae from one or two specimens of Bombycid, 

 Agaristid and Arctiiad moths by snipping them off near base 

 with scissors. The remaining stumps were usually not more 

 than an eighth of an inch long. The effect seemed to be that 

 the mutilated moths became quite helpless but active. The 

 flight was irregular and all locomotion tended to be circular 

 or one-sided ; if one stump was longer it seemed to have more 

 control, the movement being in relation to it and probably 

 causing the circular flight. In one moth, the stumps were 

 in constant movement and the insect appeared to be trying
