PREFACE. 



The aspect of these regions indicates that they are especially 

 adapted to Aculeate Hymenoptera, and the following list shows 

 that Mr. Lord has made an extensive collection of them, and 

 that he has discovered numerous new species, though many of 

 this tribe were published by Klug in the work which is here 

 often quoted. Mr. Frederick Smith, of the British Museum, 

 has kindly arranged the specimens and has named many of the 

 species already described. 



Very few of the species here enumerated are natives of North 

 Europe ; several of them inh^ibit the Mediterranean region ; 

 others have a wider range, and extend to South Africa and to 

 West Africa, or to Hindostan. The other tribes of Hymenoptera 

 are very slightly traced, excepting the Chrysidte and the genus 

 Bracou. The Chrysidse are well represented, and the coloured 

 wings of these species of Bracon are significant of the great heat 

 of their dwelling-place. 



The Insects were found in the following localities : — 



Egypt. 

 Cairo. Shoobra. Heliopolis. Red Mountain. Geezech Pyramids. 



Africa, near the Red Sea. 



Berenice. Souakin. Hor Tamanib. Massowah. Sheykh Berout. 

 Akeek (Island). Harkeko. Dahleck (Island). Rafla (Annesley
