CUERENT NOTES. 379 



? , shows that these two are in reality identical species. The number 

 of Knjcinidae in Trinidad, compared with the poverty of the same 

 family in other West Indian Islands, alone indicates the different origin 

 of its fauna, and suggests affinity with that of the mainland of 

 Venezuela, which, at the nearest point, is but seven miles distant. 



At the same meeting Dr. Chapman exhibited specimens of Par- 

 nassiKs apollo taken last July in Castile and Aragon (Spain), as well as 

 a number of specimens of Ijoth P. apollo and P. deliiis, chiefly Swiss 

 and French, taken by himself, Mr. Tutt, Mr. A. H. Jones (at Digne), 

 and Mr. Rowland-Brown (at Susa, N. Italy), both for comparison 

 with the Spanish specimens and to illustrate the extent to which the 

 races of these species approached each other in Western Europe. He 

 noted that the Spanish specimens differed from most of the others in 

 their great size, male specimens reaching 3|- inches in expanse, and females 

 3f . The Spanish 3' s agree with apollo in the only point of distinction 

 between that species and delius that makes some pretensions to absolute 

 constancy, viz., the coloration of the shaft of the antennjB. With 

 delius they agree in a certain amount of creamy tinting and apparent 

 density of the white scales, which, in nearly all races oi apollo, are white 

 and with a certain suggestion of transparency. They agree also with 

 delins in the small amount of the dark (and semi-transparent) marginal 

 coloration of the wings, the hindwings being as free from such 

 markings as the most typical delius. They agree also with delius in 

 the comparative smallness of the black marks both of fore- and hind- 

 wings, and in the tendency of these to display red nuclei. Both males 

 and females seem to be exceedingly close to the Asiatic form of apollo 

 called heseboliis, in general facies at any rate. These (^^ s placed between 

 ordinary Swiss apollo and delins, obviously incline much more to the 

 latter than the former in general tone of colour and intensity of mark- 

 ings. The females are very large, and vary to forms with much 

 increased red ocelli. The paleness of the red ocelli in many specimens, 

 especially of the males, is due to them not being in the freshest 

 condition. Several specimens were seen with yellow or orange ocelli, 

 but these were all in such poor condition that they were considered 

 faded and bleached specimens rather than the well knoAvn variety with 

 orange ocelli. It is probable, however, that some of these may really 

 have been orange originally. Continuing Dr. Chapman said: "The 

 specimens of apollo and delius are all labelled with localities, and I 

 need not go over them individually. It may be observed that I do 

 not present aberrations but specimens to illustrate the races occurring 

 at different localities. Delius is apparently never a large species, but 

 apollo is often as small as delius. The point that is perhaps most 

 interesting is the great ap])roach of some delius to the ordinary form of 

 apollo in the character and extent of the black markings. A specimen 

 from Evolena, though unquestionably delius by ground tint and 

 antenna, has the markings and general aspect of apollo, and another 

 specimen from Col Torrent, practically the same locality, closely 

 approaches this. Two specimens brought by ]\Ir. Tutt from Larche 

 are undoubted delius, but are, in general aspect, in absolute agreement 

 with apollo. Three other specimens with these look exceedingly like 

 them in size, markings, etc., but seem to be equally undoubted apollo, 

 I took these five specimens unset out of Mr. Tutt's field store-box, 

 where they formed a little group by themselves, and Mr. Tutt pointed
