NOVITATES ZOOLOGICAE XXIV. 1917. 63 



El Kantara and Batna in between. After two or three days at Constantine, 

 where I caught one Zygaena zuleiha among otherwise only common in.sects, we 

 returned to Alger and Dr. Hartert returned to Tring. Dr. Jordan and I spent 

 the three latter weeks of May and early part of June in Alger, Hammam R'ihra, 

 and Blida les Glacieres, and made some good collections. It was on this occa- 

 sion beyond the " Bois de Boulogne " that I first saw a living Charaxes jasius 

 in a wild state, though I had taken the larvae at Hyeres and bred some 20 

 imagines. Dr. Jordan and I chased this individual (a<J) for twenty minutes or 

 half an hour, but failed to catch it ; we also failed to catch a large ? near 

 Blida some four weeks later. 



In 1909 we arrived at Alger on February 22nd ; and after making prepara- 

 tions for our proposed journey to El Oued, we left for El Kantara, where we 

 arrived on the 29th. We made various collections there and went to Biskra 

 on March llth. We made numerous excursions to Oumash, Zaatcha, Tolga, 

 etc., and collected a certain amount. On March 25th we left Biskra in com- 

 pany with Dr. Nissen, the Danish Consul, on our desert trip to El Oued. On 

 this trip very few Rhopalocera were seen, though many interesting moths, 

 among them Lymantria oberthiiri were added to the collection. We reached 

 El Oued on April 7th and arrived back at Biskra on the 22nd. The two 

 principal new species found on this trip were Cleoplmiui pictiirata and Euhlemma 

 deserti Rothsch. Our friend Dr. Nissen returned to Alger, and on April 30th 

 we went for five days to El Kantara ; and then spent ten days at Batna 

 and Lambessa, from whence we went to Hammam Meskoutine. We stayed 

 here till early in June. 



In 1911 we reached Alger on January 21st, and spent the days from 

 February 1st to 18th at Hammam Meskoutine ; from February 19th to March 17th 

 we remained in Biskra, and from March 17th to 27th at El Kantara, and then 

 returned to Alger. On April 1st we left Alger with Dr. Nissen for our trip by 

 automobile to Gharda'ia. This journey was very fruitful in lepidoptera, and 

 it was on our return journey on April 28th that we took for the first time 

 Euchloe tagis pechi, which Dr. Nissen discovered while we were detained at 

 Guelt-es-Stel by an accident. On AprU 30th we returned to Alger, where we 

 were detained for a fortnight by my being Ul with fever. We spent May 17th to 

 26th at Hammam R'ihra, where we caught much of interest ; a long series of 

 Zygaena theryi Joan, and a specimen of Haemoirhagia fvciformis being specially 

 noteworthy. We left Alger on June 14th. 



In 1912 Dr. Hartert and Carl Hilgert went to In-Salah. They left BLskra 

 February 20th, and got back to Alger on June 21st. This trip was very fertile 

 in new forms, Melitaea didyma harterti, Anumeta major, Anumeta sahulosa, 

 Odontelia griseola, Polia cinnamomeogrisea, etc., 38 species and subspecies 

 apparently being new to science. 



In that same year Dr. Jordan and I spent March and the first half of April 

 at Alger and Hammam R'ihra, and then the last half of April in company with 

 Dr. Nissen at Guelt-es-Stel. The first half of May we spent at Khenchela, and 

 then returned to Alger, reaching home early in June. 



In 1913 we reached Alger on AprU 2nd, and arrived at Oran on April 9th. 

 After exploring the neighbourhood we went to Tlemcen on the 18th and col- 

 lected as far round as Lalla Marnia and Terni. We returned to Oran on the 29th, 

 where we were joined by Dr. Nissen and started for Ain Scfi-a, and we arrived
