breeds in the Siredoii state, like the Axolotls ti'oiii the table lands 

 of Moxieo. This interesting metamorphosis, whieh has apparently 

 never before been observed, venders it extremely probable that all 

 Siredons are mertsly larval salamanders; and it also leads to the 

 suspicion that some, at least, of the other so-ealled Perennibranchi- 

 ates (by no means a natural division of the Batrachia) may also 

 prove to be the undeveloped young of well-known species. 



Section of Entomology. September 22, 1868. 



Mr. P. S. Spragne in the chair. Ten member.s present. 



Mr. F. G. Sanborn exliibited a specimen of Tramea lacerata 

 Hagen, taken at Chelsea Beach, of Myrmeleon ohsoletum 

 Say, captured at Salem, by Dr. PI P. Colby, of Myrmeleon 

 abdominalis Say, at Milton, by Mr. J. Sclioliekl, and a bred 

 specimen of Mtleoina Signoretii Fitch, with its cocoon and 

 subimago-case, obtained in Audover; none of these species 

 have been hitherto recorded fi"om Massachusetts. He also 

 drew attention to the following curious specimens : a Musca 

 harpyia Harr., im]>aled upon the point of a spire of Carex (?), 

 which penetrated the body from beneath, between the an- 

 terior coxae, backward, without reappearing above ; the speci- 

 men was otherwise uninjured. An Artimophila gryphus 

 Smith, clasping a small oak twig with its mandibles and feet, 

 the body elevated one-fourth of an inch above the twig and 

 the head directed toward its extremity. 



Mr. C. S. Minot stated that there were three broods of 

 Ghrysophamis americmms, one appearing early in May, the 

 second in July, and the third the last of Augtxst. The in- 

 sects of the first brood differed fi-om those of the other tAvo 

 in wanting the row of red spots on the underside of the 

 secondaries.
