Three New South American Coccidae. 



BY T. D. A. COCKERELL. 



Aspidiotus riverae n. sp. 



9. Scale about 3 mm. long, oval, moderately convex, rough, grayish 

 brown, with the large uncovered ochreous exuviae near one end. 



9 .Length about 1890 [>- ; mouth-parts large, about 137 I* broad ; an- 

 tennse represented by a minute tubercle with about five short bristles ; 

 anal orifice about 137 fJ< from hind end, and about 15 /* long ; hind end not 

 strongly chitinized, and with no long fusiform processes, but with many 

 submarginal glands, and a row of transverse ones, very much as in Chio- 

 naspis hikosani Kuwana : five groups of circumgenital glands, median 7, 

 cephalolaterals 21 to 22, caudolaterals 22 to 23 ; no noticeable spines or 

 squames ; lobes little developed, represented by three pairs of broad low 

 rounded prominences, all wide apart, the margin between them, and 

 especially beyond the third, irregular with more or less angular promi- 

 nences ; sides of hinder part of insect finely transversely striated. 



Larva with antennae 75 ^ long, last joint long and slender, about 25 ^ 

 long ; eyes (after mounting) very dark blue. 



Hab. Province of Arauco, Chile, on stems of Chusqiica sp. , 

 graminaceous plant (Manuel J. Rivera). This is not a genuine 

 Aspidiotus; it looks like an Od^nuspis or possibly a J'scHdaoni- 

 dia, but it seems to represent a ne\v group not yet named.
