A CONTRIBUTION TO THE KNOWLEDGE OF THE NEUROPTEROUS 



INSECTS OF ALGERIA. 



By R. F. LONGINUS NAVAS, S.I. 



THE following list is the result of the study of a small collection of Neuroptera 

 collected in the year 1913 by Lord Rothschild and Dr. Ernst Hartert, and 

 in the year 1914 by the same Dr. Hartert and his assistant, Mr. Carl HUgert. 

 All the species are interesting and worthy of mention, at least for the locaUties. 

 All the specimens are in my collection, presented to me by Dr. Hartert, to whom 

 I offer here my warmest thanks.
