arundinis {typhce) bred from Shorehara pupae ; one was of a reddish-black, and 

 another mahogany on the fore-wings. He made some remarks upon the cleansing 

 of the bodies of these and similar insects. A considerable discussion ensued on this 

 subject. — Hy. J. TuBNEE, Ron. Secretary. 



Entomological Society of London : October Qth, 1897. — The Rev. Canon 

 FowLEB, F.L.S., Vice-President, in the Chair. 



Mr. W. fl. Bennett, of 15, Wellington Place, Hastings ; and Mr. B. Tomlin, 

 of 59, Liverpool Road, Ch .ster ; were elected Fellows of the Society. 



Mr. Merrifield exhibited specimens of Aporia cratcegi and Argynnis Paphia, 

 subjected to high and low temperatures during the pupal stage. In both species 

 the examples which had been cooled were much darkened. Mr. Tutt showed for 

 comparison the extremes of over 500 examples of A. cratcegi, bred or captured in 

 Kent between 1860 and 1868, but none were so marked as those which had been 

 artificially treated. Mr. Tutt showed a remarkable melanic aberration of Nemeophila 

 plantaginis, in which all trace of the pale ground colour of the hind-wings was lost ; 

 also a series of Abraxas ulmata, captured during the past summer by Mr. Dutton 

 in the neighbourhood of York. Previously aberrations of the species had been 

 rare, but a large number of this series were suffused with blue-grey or smoky- 

 ochreous. Many of the aberrant forms were cripples. He also showed, for Dr. 

 Riding and Mr. Bacot, bred specimens of both broods of Tephrosia bistortata from 

 Clevedon, Somerset, and bred specimens of T. crepuscularia and its ab. delamerensis 

 from York. Hybrids were exhibited between T. bistortata ( ^ and ? ) and T. cre- 

 puscularia (? and (?), between the former and the form delamerenns (? and ^), 

 and between the two latter crosses. The offspring of the first crosses were roughly 

 divisible into two groups following the parent forms, those of the second tended to 

 become mongrel in appearance. Hybridization led to the production of continuous 

 broods, and certain broods tended to produce males only. The coloration became 

 more intense with increase in the duration of the pupal stage. Dr. Dixey drew 

 attention to the experiments on hybridization recorded in Dr. Standfuss's " Hand- 

 buch der Paliiarktischen Gross-Schmetterlingen," and gave a summary of the results. 

 Mr. Champion showed, for the Rev. J. H. Hocking, an example of the long-bodied 

 moth, Satacoma agrionata, from New Zealand ; also one of Protopaussiis Walkeri, 

 Waterh., from China, the subject of a later communication ; and specimens of the 

 rare British Hemipteron, Emblethis verbasci, F., from the Scilly Isles. Mr. Jaeoby 

 showed a Halticid beetle, with a singular abnormality, the side-margin of the pro- 

 thorax being split and embracing a long process. Dr. Chapman exhibited and 

 described varieties of Spilosoma lubricipeda and Acronycta psi bred by Dr. Riding. 

 In the latter species the characters of the different races were very stable. Mr. Burr 

 exhibited a Mantis, Phyllocrania illudens, from Madagascar, with a close resemblance 

 to the dead leaves among which it lived, some of which were shown with it. A new 

 British Coccid, Kermes variegatus, from Kent, was exhibited by Mr. Waterliouse. 

 Mr. Gr. C. Griffiths read a paper on " The Frenulum of the Lepidoptera." Mr. 

 Kirkaldy communicated a " Preliminary Revision of the Notonectidre, Part I ;" 

 and Mr. Waterhouse a " Description of a new Coleopterous Insect of the family 

 Paussida." — W. F. H. Blandfoed and F. Mebeifield, Bon. Sees.
