Described from fourteen females, eleven males (type, allotype, and 

 paratypes a to w) reared from a Lecanium on linden, Ermclunden, 

 Sealand, Denmark, June, 1906 (J. P. Kryger). The follomng mate- 

 rial, wliich may be considered as metatypes, also examined: Many 

 specimens of both sexes reared with the above types, preserved m 

 alcohol; seven males reared from a Lecanium on oak, Dyrehaven, 

 Sealand, Denmark, July 12, 1907 (J. P. Kryger). Coloration of all 

 the above specimens including the types has been modified to some 

 extent by long immersion in alcohol, the face and cheeks especially 

 having been discolored so as to resemble the front with a slight 

 pinkish tinge. Also one female, one male on "minuticn nadcln" with- 

 out data, determmed by Mayr as A. imndipes, the female having a 

 narrow cross band of white on the orange-colored or upper part of 

 face; and seven females, seventeen males reared from Lecanium 

 fuscum (Gmelin) on oak, England, June, 1890 (J. W. Douglas), the 

 females having the mesoscutum behind the transverse lines and the 

 scutellum more dusky than usually.
