XEW SPECIES OF DIASPIXE SCALE IXSECTS. 23 



together with lobes a Kttle more yellow than the pYgidium, but not 

 strongly chitinized; plates numerous, long, filiform, central ones sim- 

 ply branched; spines short, inconspicuous; basal dorsal thickenings 

 not strongly developed or chitinized ; anal opening much larger than 

 median lobes, broad oval, about one lobe's length from tip; paragen- 

 ital pores wanting; dorsal pores not numerous or conspicuous, but 

 with very long (one-half width of pygidium) internal tubes; ventral 

 thickening of integument extending from median lobes practically 

 V,' anting. 



Ty^e.— Bureau of Entomology No. 7695. On thick, narrow, 

 slightly oblanceolate leaves about H inches long; collected by Mr. 

 Charles P. Lounsbury, at Mitchells Pass, South Africa, January 29, 

 1897. 



Note. — This species, in character of scale and last segment, is dis- 

 tinctly a Hemiherlesia. The anal opening is relatively as large as in 

 camellise, but the median lobes are much smaller, and the chitinization 

 of the last segment is distinctly less than in cameUise. The scale 

 occurred scatteringly on both surfaces of the leaves. 



ASPIDIOTUS (HEMIBERLESIA) POPTJLARUM n. sp. 



(Plate Y. fig. 2.) 



Scale of female: Length, 2 mm.; broad oval, of the camellise type; 

 strongly convex; exuvise near the anterior end, dark bro^\Ti, the 

 larval exuvia nearly black, normally covered; secretionary matter 

 yellowish white, very dense. 



Scale of male: Length, 1 to 1.5 mm.; of the normal oval shape, with 

 the larval exuvia sho^^'ing prominently at one end through scanty 

 secretionary covering. 



Adult female: Normal top-shaped, in balsam hyaline; 1.5 mm. in 

 diameter; anal jilate broad, rounded, tip slightly more yellowed than 

 the body; median lobes large, close together, slightly converging, and 

 with two distinct lateral shoulders, often lost in old worn specimens; 

 second and third lobes of ancylus type or practically wanting; thick- 

 enings of first and second incision prominent, subequal; plates rather 

 short and inconspicuous, doubtless partly lost or reduced by age and 

 use; spines normal; anus very large, broad oval, distinctly larger as a 

 rule than median lobes; paragenitals in four groups, anterior groups 

 3-9, posterior groups 3-8, often nearly continuous; dorsal pores very 

 numerous, chiefly confined to two irregular double lateral rows extend- 

 ing from the second incision, and a third inconspicuous incision; basal 

 dorsal thickening linear, not especially prominent. 



Type. — Bureau of Entomology No. 8370. On cottonwood, from 

 Deming, N. Mex., through Prof. T. D. A. Cockerell, February 9, 1897.
