My appeal for help from American entomologists has been almost 

 fruitless, only one observer having come to my aid. I want very 

 specially Heodes fiddcni, Chalceria snowi, cuprcus, rubidus; Stityriinn 

 fuliijinosa. I should like also some specimens of Gaeidcs .vanllioides, 

 cditha and gorgon. May I again appeal to brother entomologists on 

 your side of the water for help. Palaearctics, exotics or cash given in 

 exchange. G. T. BKTHUNE-BAKER, 19 Clarendon Road, Edgbaston,
