IV PREFACE. 



It will be observed that the only one of Clemens' 

 species I have personally bred and had the pleasure of 

 seeing alive was Aspidisca splendoriferella (p. 105) ; 

 and strangely enough I received from Lord Walsing- 

 ham last autumn a number of the cases of a closely 

 allied species of Aspidisca, by which the aspen leaves 

 near Fort Klamath, Oregon, were perfectly riddled 

 with holes (one leaf has had at least 150 cases cut 

 out of it). Of this species I have already had the 

 pleasure of breeding and setting out eleven specimens; 

 it can scarcely be identical with A. splendoriferella (a 

 Crataegus feeder) from the different food plant, but it 

 would be hard to say wherein the imago differs.
