§ 1. Proper Wood for Insect-boxes. — A discussion of the merits 

 of different woods for use in the construction of insect boxes showed a 

 preference among the members of the Club for the woods of the Aspen 

 (Populus freinuloides), Tulip (Liriodenilron tulipifera) and Bass-wood (Tilia 

 americana). Baron Osten Sacken says that the resin contained in pine 

 wood (Pinus slrobus) exhales as a vapor, which eventually combines with 

 the fat of the specimens enclosed in the box and renders them greasy. It 

 was suggested that a number of persons who wished to have boxes made 

 of these woods should combine together to purchase some trees for the pur- 

 pose, as these woods are not generally offered for sale in the market.

§ 2. Ocytes Seminole in Massachusetts. Mr. S. II. Scudder 

 exhibited a single female of Ocytes Seminole taken by Mr. R. Thaxter in 

 the marshes near Belmont, Mass. It has not before been recorded north of 

 Florida, and in its markings stands midway between specimens from Flor- 

 ida and Texas, exhibited with it. Other species of the genus were also 

 shown for comparison. 



Dr. Hagen said that Florida Pseudo-Neuroptera are found on Cape Cod. 



Mr. Scudder remarked that southern butterflies not infrequently occur 

 in a narrow belt of country near the sea shore, as far north as New Hamp- 

 shire. 



§ 3. Protiioracic Glands in Lepidopterous Larv.e. Mr. S. H. 

 Scudder exhibited an inflated caterpillar of Argynnis Cybele, in which 

 the prominence often seen on the under surface of the first thoracic seg- 

 ment of butterfly caterpillars was unusually large, and presented a trans- 

 verse slit. It is probable that this organ secretes fluid for softening the 

 leaf before eating, and Mr. Scudder queried whether the glands which 

 supplied the fluid might not bear some relation to those which feed the 

 osmateria of the Equites. Mr. Guenee had described an extensile pro- 

 tuberance with a transverse slit on the dorsum of the seventh abdominal 

 segment in the larva of a European Lycaena, which when subjected to 

 pressure emits a fluid. 



No. 11 was issued March 12, 1875.
