From a number of Teras terminalis galls, Mr. Walker collected more 

 than 55,000 specimens belonging to 75 species distributed as follows. 

 Coleoptera 9 species, 191 specimens ; Orthoptera i sp., 5 specimens ; 

 Neuroptera 2 sp., some hundreds of specimens ; Hymenoptera {Cyni' 

 pidae) 4 or 5 species, 30,246 specimens ; Hymenoptera (parasitic) 

 45 sp., 24,417 specimens; Diptera 2, sp., 23 specimens; Lepidoptera 

 5 sp., 9 specimens; Hemiptera 5 sp., 51 specimens; Arachnidae and 

 Acari 5 or 6 sp. 



All the Coleoptera, Otihoptera, Neuroptera, Diptera, Lepidoptera^
