364 THE ENTOMOLOGIST. 



Mr. Osbert Salvin, Prof. Poulton, and the President continued the dis- 

 cussion. Dr. Sharp read the following extract from Dr. Livingstone's 

 ' Narrative of an Expedition to the Zambesi,' and stated that he was 

 indebted to Mr. Gahan for caUing his attention to it : — '• We tried to sleep 

 one rainy night in a native hut, but could not because of attacks by the 

 fighting battalions of a very small species of Formica, not more than one- 

 sixteenth of an inch in length. It soon became obvious that they vvere 

 under regular discipline, and even attempting to carry out the skilful plans 

 and stratagem of some eminent leader. Our hands and necks were the 

 first objects of attack. Large bodies of these little pests were massed in 

 silence round the point to be assaulted. We could hear the sharp, shrill 

 word of command two or three times repeated, though, until then, we had 

 not believed in the vocal power of an ant ; the instant after we felt the 

 storming hosts over head and neck, &c." Prof. Poulton read a paper 

 entitled " On the sexes of larvse emerging from the successively laid eggs of 

 Sinerinthus pojmli." Mr. Merrifield, Dr. Sharp, and the President took 

 part in the discussion which ensued. Mr. W. L. Distant communicated a 

 paper entitled "On the Homopterous genus Pyrops, with descriptions of 

 two new species." The President read a paper, written by himself and Mr. 

 J. Edwards, entitled " A revision of the genus CEneis," which he charac- 

 terized as the most cold-loving genus of butterflies. He also exhibited his 

 complete collection of species of this genus, which was said to be the finest 

 in the world. A long discussion ensued, in which Prof. Poulton, Mr. 

 McLachlan, Mr. Salvin, Mr. Bethune-Baker, the Piev. Dr. Walker, 

 Mr. Kirby, Mr. Merrifield, Mr. Barrett, Mr. Blaudford, Dr. Sharp, and 

 Mr. Jacoby took part. — H. Goss, Hon. Secretary. 



South London Entomological and Natural History Society. — 

 Thursday, Oct. 26th, 1893.— J. Jenner Weir, F.E.S., Prsident, in the 

 chair. Mr. Frohawk exhibited a second brood oi Argynnis paphia from eggs 

 of var. valesina deposited in June, only one of the four specimens being of 

 the female parent form. Mr. Tutt remarked that he had bred second 

 broods of A. paphia and Vanessa urticcB. Mr. South exhibited Continental 

 specimens of Lycana beliargus with its var. ceronus, a female, blue like the 

 male, with fulvous spots on the upper side ; L. corydon and its var. syn- 

 grapha,a female, blue like the male, with dusky margins, and a specimen with 

 the fringes perfectly white ; also specimens of L, arion, some of which were 

 large in size and others dark in colour. Mr. Weir remarked that his many years' 

 attention to the " blues " at Lewes had resulted in the detection of but very 

 little variation. Mr. S. Stevens exhibited a specimen of Tinea simplicella. 

 Mr. Hamm, long series of the two broods of Leucophasia sinapis, well 

 illustrating both the seasonal and sexual dimorphism of this species ; 

 Colias edusa with several examples of var. helice, among which was a female 

 with only the faintest trace of a spot in the black border; long series of 

 Melitcea aurinia, bred from Hampshire larvae, with captured specimens from 

 Swansea for comparison ; also a remarkable scaleless aberration (some of the 

 Hants specimens were comparable to var. hibernica) ; a specimen of Poly- 

 ommatus phlceas with fewer spots on the primaries than members had 

 noticed before ; bleached vars. of both Epinephele ianira and E. tithonus ; 

 a most remarkable var. of E. hyper anthus, in which one wing only was 

 normal, the other three having the yellow rings on the under side much 

 enlarged, the colour being irregularly spread over a considerable surface, and 

 streaks protruding into the black ground colour ; a var. of Smerinthm tilicB ;
