Mr. Cresson exhibited the type specimens of Catocala Editha 

 Edwards, and Catocala Walshii Edwards, which had been sent him 

 by Mr. William H. Edwards, for the collection of the American 

 Entomological Society. 



Dr. Horn exhibited a collection of Lepidoptera made by the late 

 Mr. W. M. Gabb, in Costa llica, which had been beautifully set by 

 our fellow-member Mr. C. A. Blake. This collection had been placed 

 in Dr. Horn's hands by 3Ir. Gabb, in order that any desiderata might 

 be placed in the cabinet of the American Entomological Society. 

 The collection is principally diurnals, consisting of Morpho, Papilio, 

 Helicrmia, etc , with a few heterocera or nocturnals. Dr. Horn stated 

 that the two specimens exhibited at a previous meeting, as an instance 

 of mimicry, also belong to this collection. 



Mr. Blake stated that the collection consisted of 63 genera, 142 

 species of Bhopalocera, and 17 genera, 27 species of Heterocera.
