of observations made in connection with tlie difficult Plel)eids 

 hitherto included under the Oberthiirian classification P. agon, • 

 Schiff. (P. argns, L. ?) and P. argns, L. ? iargyrognomon, Auct. recent.). 

 As we are well aware, to confusion of species has been added con- 

 fusion of tongues in the case of P. argns. At present the type 

 appears to be known as argus, L., argyrognomon, Bergst., or idas, 

 Courvoisier, according to taste. Let us for the present stick to our 

 (sgon, and follow M. Oberthiir's argus. A detailed examination of 

 the argus group appendages (which, from the point of view of nomen- 

 clature only, I think, happily does not inhabit our islands) leads 

 Dr. Chapman to separate tlierefrom a new- and distinct species, 

 which he names /'. ciegus. It is common apparently in the Geneva 

 district, and has been taken at Budapest. The enlarged photographs 

 reveal on tlie wing under sides a considerable difference of markings, 

 and these differences are constant. I think aegus, indeed, much 

 easier to divide than thersites and icarus icarinus. Dr. Eeverdin 

 (" Note sur I'armure g^nitale male chez L. argus, L., et ses varietes ") 

 comes to the conclusion that probably, but not certainly, ligiirica, 

 Obthr. (= degus, Chpmn.), and armoricana, Obthr., are specifically 

 distinct from argus. If, therefore, ciegus and ligurica are one and the 

 same, then the range of ciegus may be found to extend over the greater 

 part of southern central Europe. Dr. Courvoisier, of Bale, con- 

 tributes his views on the androconia of these and others of the argus 

 group with drawings from the microscope, and the symposium con- 

 cludes with " Observations biologiques concernant le LyccEua alcon," 

 by Mr. Harold Powell, which deals minutely with the myrmeco- 

 philous habits of the species, and the ants of the localities where it 

 occurs in Brittany identified by Mr. Donisthorpe. The whole thus 

 forms a notable addition to our knowledge of the Lycsenids, and 

 under M. Oberthur's inspiring leadership will doubtless stimulate 

 further research to resolve the Plebeids into their final specific units.

OBITUARY. 



Frank Edward Lowe, M.A., F.E.S. 

 Born, November 27th, 1853. Died, February 21st, 1918. 



Entomology is the poorer of one of her most devoted sons by 

 the death of the Rev. F. E. Lowe which occurred on February 21st, 

 at St. Stephen's Vicarage, Guernsey, after a short illness. Educated 

 at Durham School, he graduated at Durham University Theological 

 Prizeman and Licentiate in Theology in 1875, and distinguished 

 himself as an oarsman. In 1880 he left his first curacy at Burton- 

 on-Trent, and went to the Channel Islands, and to that happy 

 circumstance and still more so, perhaps, to the interest shared 

 with Mrs. Lowe in the lepidoptera of the islands, we owe a large 

 contribution to our knowledge of the insular fauna, and latterly of
