NEUROPTEROTJS INSECTS COLLECTED BY DR. A. DONALDSON SMITH IN 

 NORTHEASTERN AFRICA. 



BY PHILIP P. CALVERT, PH.D. 



Dr. A. Doualdsou Smitli, of Philadelphia, in his expedition 

 through Somalilaud and Gallalaud to Lake Kudolph, collected 

 some Neuroptera which he presented to the Academy of Natural 

 Sciences of Philadelphia These, some twenty- seven specimens, 

 embrace thirteen species of Odonata, three of Planipennia, and 

 one Termite; among them are two new species and one new genus 

 of Odonata. This fact, together with the very slight information 

 hitherto existing on the fauna of the region, justifies the publica- 

 tion of the present paper. 



Dr. Smith has published a narrative^ of his journey, accom- 

 panied by excellent maps, and since his Neuroptera are individ- 

 ually labelled and dated, it is possible, by reference to his book, to 

 determine exactly the geographical positions and the elevations of 

 the localities whence his specimens came. The care thus taken to 

 record precise information deserves special mention, since not all 

 recent travellers, in Africa or elsewhere, have been so painstaking. 



Dr. Smith left Berbera, on the Gulf of Aden, July 10, 1894 ; 

 reached Lake Rudolph in July, 1895; thence turned southeast- 

 wardly to the Tana river and Lamu on the Indian Ocean, at which 

 latter he arrived about October 26, 1895. His Neuroptera were 

 collected at the following places: 



Berbera, on the Gulf of Aden, Onychogomphus sp., Hemianax 

 ephijijjigei; Croeothemis erythrcea, Orthetrum brachiale and 0. 

 Sabina, July 4 and 5, 1894; 



Lafarok (map) or Lafarug (text, p. 16), about thirty miles to

The Hand, a plateau with an elevation of 3,000 feet and more, 



' Through Uakno^n Africia Countries. By A. Donaldson Smith. El- 

 ward Arnold, London and New York, 1897.
