spots, one situated in front of the base of each posterior process. Dr. T. A. Chap- 

 man, several specimens sent for exhibition by Mr. W. Purdey, inchiding Leioptilus 

 carphodactylus taken by him near Folkestone, a species new to the British list ; 

 also some good varieties of Acalla crintana and a very dark L. tephradactylus, 

 looking at first sight very like L. xcarodactylus. Dr. F. A. Dixey, specimens of 

 Teracoliix aehine, Cram., and Be'enoi.t severina, Cram., bred and captured at 

 Salisbury, Mashon aland. The exhibit showed that in both species the appearance 

 of the wet season phase could be induced under artificial conditions in a brood that 

 should normally have belonged to the dry season form. The specimens of B. sever- 

 ina also exemplified the effect of moisture alone ms contrasted with moisture and 

 heat. Mr. Selwyn Image, an aberration of Odezia atrata,'L\wn., taken by Dr. G. B. 

 LongstafP at Mortehoe, N. Devon, on June 26th, 1906, displaying a general tendency 

 to albinism. Mr. W. E. Sharp showed a small collection of Coleoptera, to illus- 

 trate the tendency of some species to micromorphism, and gave an account of the 

 causes of which these small forms were the I'esult. Mr. H. St. John Donisthorpe, 

 a number of similarly stunted specimens, in further illustration of this characteristic. 

 Mr. W. J. Kaye, a series of the genus HeVieonius, arranged to show (I) how Herr 

 Kiffarth, in a paper published in 1901, entitled, " Die Gattung Heliconiux" divided 

 the genus into two main divisions by a secondary sexual character, viz. : Group I, 

 in whicli the inner margin of fore-wing of t? on under-side is composed of smooth 

 scales reaching the median nervure, and Group II, in which the smooth scales do 

 not reach ths median nervure by about a millimetre. The remarkable result 

 of the application of these characters revealed the fact that in several instances 

 what we had hitherto called one species was in reality two species, one belonging to 

 Group I, the other to Group II. Thus. Heliconius hydara was found to embrace a 

 sub-species of H. amarylUx in euryades, Riif., H. xenoclea included H. batesi. Riff., 

 and H. phyllis included H. nanna. Mr. Hamilton Druce, a case of butterflies, 

 illustrating the interesting Lyctenid genus Mimacriea, including two groups, the one 

 mimicking the Danaine, the other the Acrseine butterflies.
