Described from four females (type and paratypes a to c) reared 

 from material of leery a purchasi Maskell, Mendoza, Argentina (Carlos 

 Reed). The actual host was perhaps a Chrysopid or Hemerobiid 

 predaceous on the Icerya. The specimens are poorly preserved as 

 two of the paratypes have lost the abdomen, and the antennae are 

 missing m all except the type.

2. BBETHESIA ABNOKMICORNIS (Glrault.) 



Isodromus abnormicornis Girault, Insec. Insc. Menst., vol. 4, Jan., 1917, p. 118. 



This species has not been seen by the writer, but seems to be closely 

 allied to latifrons. Accordmg to the original description the fronto- 

 vertox is moderately wide, the second funicle joint subequal to the 

 pedicel, the last funicle joint distinctly wider than long, the pro- 

 podeum with three widely separated canmae, and the postmarginal 

 vein only somewhat shorter than the stigmal. The coloration is 

 similar, but the pronotum more blackish, the mesopleura entirely 

 black, and the abdomen except at the base solidly black. The types 

 were reared from material of Icerya hrasiliensis Hempel, Sao Paulo, 

 Brazil (A. Hempel).
