 Of the European half-hundred species, about a score are heretofore 

 found in this country. In Nat. Tidsskr. III. R. 4. B, 141-150, I. Schi/jd- 

 te has described some of them; but as his division of subgenera demands 

 exact investigation of the mouth-parts, an other is here followed (Muls. 

 et Bey). I. Schi.odte has described and illustrated several of the Bledl - 

 us larvae. (Nat. Tidsskr. III. R. 3. B., 211, T. XII.)
