84 THE entomologist's record. 



The above is the scheme of relationships of the various forms of 

 the new species worked out by Dr. Verity. 



Hence the name of the first brood of the Italio-French form of 

 aragonensis is Agriades aragonends sub.-sp. rezniceki, race rezniceki, 

 sub. race rezniceki, gen. vern. rezniceki, or in the non-informative 

 nomenclature 



Agriades aragonensis rezniceki rezniceki rezniceki rezniceki. 



Similarly the name of the first brood of the French form of arago- 

 nensis is Agriades aragonensis sub.-sp. rezniceki race constanti gen. vern. 

 constanti, or in the non-informative nomenclature 



Agriades aragonensis rezniceki constanti constanti. 



An aberrational name could be added to each of these polynomials 

 to a still further increase of perplexity. 



It will be seen from these two examples that " position " (3rd, 4th, 

 5th, etc.) does not give relationship value as does the second (species- 

 name) position, since one or more of the intermediates may not be in 

 the series of forms. Even the 2nd position name does not show 

 relationship in numerous instances, e.g., its use by Friihstorfer, etc. 



There must be absolute certainty and precision in definiteness with 

 all terms used, otherwise misunderstanding is bound to arise, hindrance 

 to progress, investigation on wrong bases, and endless muddle. 



Lepidopterology.''

The twelfth Fasciculus of the Lepidopferologie Comparee consists of 

 a thick volume of 528 pp. of text and nearly as thick a one of plates, 

 65 in number, of which 21 give fu.rther figures of the Phalaenites of 

 Guenee (and allied species), and 11 of Heliconia, Xeptis, Phengaris 

 atroguttata, and other exotic species; both these sets of plates not only 

 illustrate the species figured, but also M. Culot's inimitable genius as 

 draughtsman and lithographer. Then there are 8 plates of the append- 

 ages of Hesperia from photographs pertaining to Dr. Reverdin's 

 Revision of the genus Besperia. There are also 25 photographs of the 

 country in the- Armorican peninsula, practically more or less environs 

 of Rennes. With some of these we are told of a few of the character- 

 istic Lepidoptera that are found in the locality, but all of which make 

 a field entomologist wish he had such areas for collecting and observ- 

 ing at his command. 



Dr. Reverdin's Ecvision will deserve fuller notice than this brief 

 review permits. 



The second paper is a very interesting account of, and discussion of, 

 Ciinelia niargarita, H.G., by Mr. P. Chretien, who has succeeded in 

 rearing this rare, beautiful and puzzling species from the egg. Although 

 he says that in making such observations, amongst other conditions 

 " a certain degree of luck must also attend the hunter,'' and though he 

 had some such luck in unravelling the life-history of C. niargarita, we 

 must recognise that such luck is of little use unless it happens to the 

 right man, and M. Chretien is to be congratulated on this bit of work. 

 The moth is too rare to be known to many of the English collectors,
