the groove of a setting board; the specimen to be 

 cleansed is then placed in position with the under 

 side of the wings resting on the paper. Blotting 

 paper is now placed over the upper surface of the 

 wings, and white twine is wrapped around the board, 

 paper and specimen to keep every thing in place. 

 Gasoline is gently poured over the blotting paper, 

 being careful that none gets on the body of the speci- 

 men. The specimen is then placed in a box until the 

 gasoline has evaporated, which takes but a few hours. 

 At the end of this time if the grease has not all been 

 absorbed by the blotting paper, the operation should 

 be repeated, using fresh paper. After the second 

 operation, if not the first, we will find our specimen 

 as bright and clean as the day it was captured. 



Two Hermaphrodites 



By Samuel E. Cassino 



In No. 9 of The Lepidopterist I described a case 

 of peripheral gynandromorphism in Collosamia pro- 

 methia. The upper illustration in plate III figures 

 a gynandromorphic specimen of Sabulodes arcasaria 

 Wlk., from the collection of Mr. Max Rothke, of 

 Scranton, Pa. which was taken in August 1906. The 

 right wing of this specimen shows the maculation of 

 the female, while the left side is that of the male. 



The lower cut represents the Gypsy Moth (Porthet- 

 ria dispar Linnseus.) In this monstrosity the thorax 

 and abdomen are male. The right antenna is male 

 and the left, female. Both primary and secondary 

 on the right side have male maculations. The right 

 primary is female, while the right secondary has the 

 male coloration at the base, with dashes of the lighter 

 female markings extending from the outer edge about 

 half way to the base. This specimen was taken by 

 Mr. C. V. Blackburn in Stoneham, Mass. in 1914 and 

 is in the collection of the author. 



The incident mentioned by Dr. Holland in his 

 very excellent Moth Book in reference to the intro- 

 duction of this pest into America is not quite correct.
