gonia lyside, many specimens taken showing great variation, 

 probably heretofore described under various names ; Pyrgus 

 pastor, heretofore recorded from Mexico ; Nisoniades potrillo, 

 heretofore recorded from Mexico and Cuba. 



March j, 190+. Twenty persons present, the President in 

 the chair. Mr. Engelhardt, in extension of the discussion at 

 the previous meeting, read a paper upon " Museum Pests, and 

 Some of their Breeding Places." King crabs, lobsters and 

 other crustaceans were attacked by both the larvae of the 

 clothes moth and Anthrcnus, the ligaments being devoured to 

 such an extent as to cause the joints to separate. The larvae 

 were active in all stages in warm rooms during the winter, 

 despite contrary opinions. Bisulphide of carbon only partially 

 destroyed these pests. The feathers and rags in bird's nests 

 as well as dried bog grass, were attacked by the clothes moth. 

 Powdered naphthaline was successfully employed in such 

 cases. The book louse (Atropos divinatoria} not only devoured 

 paste or glue used in binding, but also penetrated the shellac 

 coating upon shells to reach the dried tissue beneath. Cock- 

 roaches and house crickets would devour insects while on 

 setting boards. These should be laid or hung in tight closets 

 or cabinets with powdered naphthaline sprinkled on the bottom 

 and shelves. Mice and rats would also work havoc among 

 living cocoons, or to an exposed collection, and were particu- 

 larly persistent in their efforts to reach dried specimens of any 

 kind. 



Dr. Call mentioned that Indian garments as well as the 

 feathers of mounted birds were frequently destroyed by the 

 clothes moth and that in addition to carbon bisulphide he had 

 used a toilet spray filled with corrosive sublimate dissolved in 

 alcohol in the case of infested crustaceans. 



Mr. Schaeffer suggested the thorough saturation of the inte- 

 rior of insect and other cases with carbolic acid, the odor of 

 which, in his experience, had proved permanently effective 

 without renewal. 



Dr. B. S. Middleton (of Mullingar, Ireland, visitor), stated 

 that his collection of Brazilian butterflies had been eaten 

 by cockroaches in the hold of his ship, and Mr. Franck related
