2 "S. Algeria" ! ! (Batna ? W. R.), August 1900, Dr. Standfuss. 

 1 Algiers ?. 



1 Hussein Dey, May 1909, Captain Holl. 

 15 Batna, A. Nelva. 



2 Sidi-bel-Abbes, April 1916, Rotrou. 



20 Le Kreider, Prov. Oran, April 1916, Rotrou. 

 1 larva, 4 pupae, Batna, Faroult. 

 1 larva, 1 pupa-case, Sebdou. 

 1 larva, Meridje. 



The British Jluseum has 5 specimens from Le Kreider ex Tring Museum. 

 The second or summer brood appears to be paler and with a more cinnamon- 

 rufous wash, and therefore appears much less grey than the spring brood. This 

 second brood is the form. aest. aestivalis of Austaut. 



5. Deilephila nerii (Linn.). 



Sphinx nerii Linnaeus, Syst. Nat. edit. x. p. 490. No. 5 (1758) (Europe). 



Mr. Charles Oberthiir has no direct evidence of the occurrence of this fine 

 insect in Mauretania, and so says that it must remain for him doubtful. In 

 the autumn of 1907 our Arab guide and shikaree, Sliman ben Larbi, of Biskra, 

 found several larvae of D. nerii on the oleander bushes in the river-bed at El 

 Kantara, but, unfortunately, all the pupae died without yielding a perfect insect. 

 I have one larva received from Faroult which he declared came from near Alger. 



1 larva, Alger, Faroult. 



6. Herse convolvuli (Linn.). 



Sphinx mnvolviili LinnaeuB, Syst. Nal. edit. i. p. 490. No. 6 (1758). 



This insect is by no means common in Mauretania. We have only seen 

 it once in Algeria ; I captured one on the cinematograph screen in the Cafe 

 Glacier at Biskra in 1908. 



10 Mazagan, August 1901, W. Riggenbaeh. 



1 Sidi-bel-Abbds, August — September 1916, Rotrou. 

 12 Batna, 1909-1914, A. Nelva. 

 1 Biskra, April 1908, W. R. and E. H. 



11 St. Germain, near Tunis, August — September 1905, E. Blanc. 

 1 lai-va, Alger ?, Faroult. 



The British Museum has no Mauretanian examples. 



7. Sphinx ligustri nisseni (Rothseh. and .lord.). 



Sphitix liguslri nisseni Rothschild and Jordan, Novit, Zool. vol. xxiii. p. 253 (1916) (Hammam 

 Meskoutine). 



Up to the time of writing, the single specimen taken by Dr. Nissen remains 

 the only recorded specimen from Mauretania, though Victor Faroult asserts 

 that he took a specimen in Tunisia some j'ears ago ; but this specimen seems 

 to have vanished together with a specimen of Arctia mja, also said by Faroult 

 to have been captured in Tunisia. 



1 Hammam Meskoutine, April 1914, Dr. Nissen.
