of Malacosoma lijbrid schaufussi {M. castrensis x M. neustria). The paper was 

 admirably illustrated by microscope preparations of the insects named, as well as of 

 M. franconica, shown by the aid of the micro-lantern. The author pointed out 

 that, unlike the usual mixture of male and female genitalia obtaining in the case of 

 hybrids, the sexes of schaufunsi possessod 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 ea^h of the parent species, 

 though perhaps leaning more towards neudria. The scales also showed modifica- 

 tions, being intermediate in form and size between those of the parents from the 

 same part of the wing. Mr. Fred. Bircli gave a most interesting address upon his 

 experiences in Trinidad wlien in quest of tropical Lepkloptera, with original 

 observations upon the habits and peculiarities of the butterflies of the island Tlie 

 following exhibits were made, viz. : l>y Mr. Oulton Harrison, an album of plioto- 

 graphs of Lepidoptera in tlieir various stages, taken by Mr. Hugh Main, of London; 

 also on behalf of the Rev. T. B. Eddrup, of Horbury, melanic Agrolis agathina 

 from the West Riding, Boarinia repandata from Horbury, and its variety con- 

 versaria from Barmouth. The Hon. Secretary showed, on behalf of Mr. R.Hancock, 

 of Birmingliam, a number of photographs of Lepidoptera, and read a letter relating 

 to the exhibit. By Mr. W. Mansbridge, a short series of Triphaena comet, var. 

 curtisii, from Aberdeen, and a series of the chocolate form of Hemerophila abruptaria 

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

 melanic specimens of A. agathina from Delamere for comparison with Mr. Eddrup's, 

 more smoky in ground colour than the West Riding specimens. Mr. Oscar 

 Whitaker, lantern slides of the exotic cockroaches Blabera giganlea and B. 

 marmorata from the collection of Mr. E. J. B. Sopp.

The Chairman communicated a paper entitled " Micro- Lepidoptera captured 

 in Lancashire and Cheshire during 19(i6," and illustrated his remarks by specimens 

 of all the moths referred to ; there were no rare species among them, but about 

 thirty additions to recent records were mentioned. In illustration of the Tortrices 

 of North Lancashire, Mr. C. H. Forsyth, of Lancaster, sent a box of some ninety 

 species, collected mainly in the neighbourhood of Lancaster, including Sciaphila 

 penziana from^' Avonside, Conchylis alternana, Aphelia osseana, Grapholitha pen- 

 kleriana, and Dicrorampha satnrnana from Lancaster. This exhibit proved a very 

 useful contribution to our records for the northern part of the county. Mr. Robert 

 Adkin, of London, sent for exhibition a pair of the Tortricid moth, Tortrix pronu- 

 bana, one of the most recent additions to the British list. Other exhibits were a 

 series of beautiful water-colour drawings, illustrating protective coloration in 

 butterflies and moths, by Mr. Newall, of New Brighton ; and by Mr. Richardson, 

 several cases of insects for educational purposes.— H. R. Sweeting and Wm. Mans- 

 BEIDGE, Hon. Sees.
