The data for specimens given under Mr. A. E. Gibbs are taken from "An 

 Algerian Holiday " in The Entomologist, vol. xliv. pp. 135-140 and 170-174 

 (1911); those given under Joannis are taken from the Bulletin de la Societe

I herewith give a sort of synopsis of the people named in the lists of Ti ii.g 

 Museum material. 



Dr. Nissen is Danish Consul-General for Algeria and a medical practitioner ; 

 he has a private collection of Algerian lepidoptera and a small representative 

 one from elsewhere. 



Captam Holl, who died in 1916 or the end of 1915, was a retued engineer 

 oflScer of the French Army ; he was an Alsatian, and had a collection of 

 Algerian and Alsatian lepidoptera and disposed of his duplicates commercially. 



Mr. A. Nelva is the principal pharmaceutical chemist at Batna ; he originally 

 collected all orders of zoological objects, but in 1909 determined to restrict 

 himself to coleoptera. However, he could not forgo retaining small series of 

 his local lepidoptera, but collects lepidoptera mainly for sale. 



Mr. Maxime Rotrou is a coleopterist who habitualh- lives at Sidi-bel-Abbes, 

 but travels about in the Province of Oran, being m Government employ. He 

 collects lepidoptera and other orders for sale to help him with his coleoptera. 



Mr. A. Thery is a merchant and commission agent of Alger, who has one 

 of the best collections in the world of the coleopterous family of Buprestidae, 

 and made also a collection of Algerian insects. Just before the war he took 

 up a large land concession near Rabat and sent me a small collection from 

 there. 



Victor Faroult is a French professional collector who has collected for me 

 in various parts of Algeria since 1911. 



Cheli Brahim is or was the Arab guide at the Hotel Bertrand at El Kantara. 



Mr. E. Blanc is a taxidermist and dealer in Tunis. 



W. Riggenbach is a Swiss zoological collector who collected for the Tring 

 Museum in Morocco from 1900-1905, and in Senegal in 1906-1907. 



Except in very few instances no insects received in 1916 could be included, 

 as owing to the war I have not been able to get them set. I received in 1916 

 from Mr. Nelva, Mr. Rotrou, and Victor Faroult some five or six thousand 

 specimens from Perregaux, Sidi-bel-Abbes, Titen Yaya, Lambessa, Environs de 

 Batna, Hammam R'ihra, Djebel Zaccar (above Miliana), and Aflou. 



I have in the lists of specimens only used initials when quoting cur own 

 captures. E. H. signifies Dr. Ernst Hartert ; K. J. signifies Dr. K. Joidan ; 

 C. H. signifies Carl HUgert and W. R. denotes myself. 



The localities are arranged from west to east and from north to south and 

 from south to north. 



[Papilio machaon Linn. 



Mr. Oberthiir states quite truly that it is not very easy to define the different 

 subspecies of this butterfly which inhabit Barbary. But I think I shall be able 

 to make it quite clear that there are three distinct races inhabiting this area. 

 (1) That found along the coast and down to the centre of the " Hants Plateaux " 

 in Central and Eastern Algeria and Tunisia ; (2) that inhabiting the coastal
