illustrated by microscope preparations of the iu sects named, as well as 

 of M. francunica, shown upon the screen by the aid of the micro-lantern. 

 The author pointed out that, unlike the usual mixture of male and 

 female genitalia obtaining iu the case of hybrids, the sexes of sc/iaujussi 

 possessed unmixed organs proper to the respective sexes. From a 

 consideration of the details of the structure of the hybrid moths they 

 are seen to combine the distinguishing features of each of the parent 

 species, though perhaps leaning more toward neustria. The scales 

 also showed modifications, being intermediate in form and size between 

 those of the parents from the same part of the wing. — Mr. Fred. Birch, 

 who shortly sails for Brazil upon a collecting expedition, gave a most 

 interesting address upon his experiences in Trinidad when in quest of 

 tropical Lepidoptera ; his original observations upon the habits and 

 peculiarities of the butterflies of the island were much appreciated by 

 the members present. — The following exhibits were made, viz., by Mr. 

 Oulton Harrison : An album of photographs of Lepidoptera in their 

 various stages, taken by Mr. Hugh Main, of London ; also, on behalf 

 of the Rev. T. B. Eddrup, of Horbury, melanic Agrotis aguthina from 

 the West Eiding, Buaimia repanduia from Horbury, and its variety 

 conversaria from Barmouth. — The Honorary Secretary showed, on 

 behalf of Mr. R. Hancock, of Birmingham, a number of photographs 

 of Lepidoptera, and read a letter relating to the exhibit. — Mr. W. 

 Mansbridge, a short series of Triphcetia cumfs var. curiisii from Aber- 

 deen, and a series of the chocolate form of Hetnerophiia abniptaria from 

 the London area, together with examples of the type for comparison ; 

 also melanic specimens of A. agatlnna from Delamere for comparison 

 with Mr. Eddrup's ; they were seen to be more smoky in ground 

 colour than the West Riding specimens, appearing quite dull beside 

 them. — Mr. Oscar Whitaker exhibited lantern-slides of the exotic 

 cockroaches Blabera gigantea and B. marniorata from the collection of 

 Mr. E. J. B. Sopp.

 of interesting and valuable suggestions for individual as well as collec- 

 tive furtherance of our studies, and instanced the remarkable work
