 Description of a Monstrous Female Imago of Anisopteryx 



POMETARIA, WITH E.EMARK3 OX THE PUPA. By B. PlCKMAN 



Mann. 



On the 9th of November, 1873, I caught a female Anisopteryx 

 pometaria Harr. descr., which has two aborted wings on each side, and 

 has pectinated antennae. The normal female is wingless, and has 

 simple antennas. In this specimen the right fore wing is about 6.5 or 

 7 millimeters long; a fraction of a millimeter thick at the base, and 

 as far as the middle; dilated at the middle into a flattened spheroidal 

 bunch; thence slender to the tip. The right hind wing is about 

 3 mm. long and 1 mm. wide. The left fore wing is about 3.5 mm. 

 long, and 0.5 mm. wide. The left hind wing is about 4.5 mm. long, 

 and nearly 1 .5 mm, wide. All the wings are clothed with scales, 

 and have somewhat the appearance of fur tippets. 



1 A mutilated specimen has since been taken alive in Coomb's Cove, which per- 

 haps is the same mdividual referred to in the letter. Its body is said to have been 

 as large round as a hogshead, and ten feet in length; the long arms measured forty- 

 two, and the shorter, six, feet in length. See Am. Nat., Feb., 1874, p. 122; and Sill.
