266 THE entomologist's record. 



three male forms ; O. jiuseidon Vkh. valentina, 3; 0. }>oseidon, $ form 

 hirsrin ; (). poseidon 2 form bnmneus : 0. paradisea, J ; and (>. para- 

 (lisca, a variety not showing the golden streak situated towards tail of 

 hind wing and having in consequence green marginal area of hind- 

 wing much increased. 



He also exhibited the following species of MorpJiu, M. heciiba, 

 M. jiistitiae, M. aiiip/iitrioji, ]\J. cacira, M. rlii tenor, and M. aureola. 



Mr. W. West (Hon. Curator of the Society) exhibited the fourteen 

 drawers of the type reference collection of the Society which have been 

 completely rearranged since the large additions made by the donation 

 of Mr. W. G. Dawson, of Abbots Morton, Worcester. 



Mr. C. P. Pickett exhibited four cabinet drawers of his wonderful 

 collection of the forn:is of Ant/erona prttnariu, the results of seventeen 

 years of inbreeding and of four years of experiments in exposing the 

 larvas to various colour environments. The results obtained under the 

 latter conditions are somewhat remarkable as the following summar3'- 

 shows : 



Larvje ted up under pink muslin : — There was a tendency to reduce 

 the size of the bands and many specimens are paler. 



Larvte fed up under red muslin : — There was a tendency to greatly 

 increase the size of the bands and many specimens are darker. 



Larv;e fed up under yellow muslin : — There was a tendency to 

 produce a deeper yellow ground. 



Larvae fed up under green muslin : — There was a tendency to kill 

 the yellow and orange, the former colour becoming more whitish and 

 the latter more orange yellow. 



During the seventeen years of the experiments there have been 112 

 broods, from 15,955 ova, producing 13,476 larva? and 10,095 miagines. 



Mr. Pickett also exhibited very long series oi A;/ riades coridon taken 

 during the last four seasons in the Herts district, and showing much 

 extreme variation. There were included lovely specimens of the ab. 

 seiiiisjpiiira/dia, ab. ijiacijiialis, ab. fitriata, ab. ohnoleta and the newlj'' 

 differentiated asymmetrical gynandromorphic females with one side 

 smaller than the other, the smaller side always containing some amount 

 of androconial scales. One extreme aberration was a remarkable 

 albino 3 whitish over the entire upper-surface without dark margin, 

 and another extreme aberration a g- with the black margin extending 

 uniformly and wide round the margins of the hindwings as well as of 

 the forewings. 



Th9 Rev. F. D. Motice exhibited a collection of British ('hryaididae 

 and a collection of the more conspicuous species of Pabisarctic Chnjsididae 

 (non-British) and stated that this group of brilliantly coloured Hymen- 

 optera were parasitical on the wood-burrowing bees and sand wasps. 

 It was somewhat remarkable that the British and many Pala'arctic 

 species were much more brilliantly coloured than their tropical 

 relatives. 



Mr. B. S. Curwen exhibited series of European Parnassiids Ihirith 

 apidliiiiis, Paruassiiis apollo, I', deliiis and /', lunemosi/iie with several 

 aberrations ; series of L)/caena avion, L. arca^, L. eiiplieiniis, L. alcon 

 and L. iolas with Vohjonnnattis aiiianda : and several aberrations of 

 Apatiira ilia including ab. iliadet> taken near Laon in early July of 1914. 



Mr. A. W. Mera exhibited a series showing the variation obtainable 

 in Psiliira iiwnacha. The series included examples ranging from
