scape with a longitudinal, more blackish stripe through middle of the 

 outer surface, the base and the dorsal, inner margin yellowish white, 

 the pedicel becoming yellowish white on upper side at apex. Legs as 

 m the female except that the tibiae have a famt dusky shading on 

 their outer surface. Wmgs hyalme, the veins pale brownish. 



Described from nineteen females, seven males (type, allotype, and 

 para types a to x) reared from Lecanium coryli (Lmnaeus), Dyrehaven, 

 Sealand, Denmark, June, 1906 (J. P. Kryger). The following meta- 

 types also examined: Four females swept from grass, Gentofte, 

 July 13, 1905; six females, five males reared from a Lecanium on 

 linden, Dyrehaven, June 16, 1906; and two females, one male reared 

 from the same host, Ermelunden, June, 1906, all localities \n Sea- 

 land, Denmark (J. P. Kiyger). Also one female, one male badly 

 broken, labeled "Germany" and determmed by Mayr as A. punctipes. 



The synonymy given above can be verified only by the examina- 

 tion of material in the European collections, but is presumal)ly cor- 

 rect. Walker's description of liederaceus agrees fairly well with the 

 male of this species.

Female. — Front and vertex about three times as long as wide; 

 ocelli in a very acute-angled triangle, the posterior pair close to 

 eye margin; antennal scrobes shallow and broad; front and vertex 

 thickly pubescent, the eyes with a short, sparse pile. Antennal 

 scape about one-third as wide as long, widest just beyond the middle; 

 pedicel a trifle longer than the first three funicle joints combined; 

 first four funicle joints of nearly equal length, the fifth about twice 

 as long, the sixth somewhat shorter than the fifth, all wider than 

 long except the fifth and increasing gradually in width distad; club 

 oval, rounded at apex, about one-third wider than the precedmg 

 jomt and as long as the last four joints of funicle combined. Wmgs 

 uniformly and densely ciliated; oblique hairless streak narrowed 

 above and not nearly reaching the stigmal vein, interrupted below 

 with the cut-off portion widely separated from the posterior margin 

 of wing. Length: 1.2 mm. 



Front and vertex bright orange yellow; face and cheeks pale rose 

 color (this coloration undoubtedly due to immersion in alcohol at 

 some former time, the original color probably some shade of yellow 

 paler than vertex or no turn), a narrow streak of blackish brown on 

 lower corners of cheeks continued across the oral margin of face; 

 mesonotum pale orange yellow with a transverse blackish brown line 

 on each side of the base of the scutum; concealed part of occiput
