Dorsal surface : Minute 8-shaped and disk pores fairly sparse ; tubular ducts 

 30 fi long ; dorsal tubes present. 



Ventral surface : Antenna short, with 2 setae longer than diameter of antenna ; 

 usually 2 quinquelocular pores between antenna and margin ; beak without setae ; 

 spiracle with bar fairly broad, and with atrium slightly enlarged and containing 

 3-5 quinquelocular pores, a total of 10-19 pores in atrium and in the row extend- 

 ing to body margin from spiracle, this row usually single near spiracle but 3 or 

 4 pores wide at margin ; 2 or 3 dark-rimmed 8-shaped pores each side of beak, a 

 few scattered on anterior end and in lateral area posterior to mouth parts, others 

 arranged in 4 or 5 transverse rows near posterior end of abdomen; submarginal 

 8-shaped pores usually in a double row, the inner row well removed from the 



Pouter, terminating near genital opening, usually 2 pores opposite every other 

 marginal 8-shaped pore ; 7 pairs of submarginal setae posterior to anterior 

 spiracles, the posterior pair nearer to the posterior pair of marginal 8-shaped 

 pores than to the apical setae ; 1 pair of setae posterior to genital opening, 1 pair 

 anterior to opening, and 1 pair anterior to the latter. 



Apex of abdomen : Slightly concave ; setae, apical 18-20 n long, interapical 

 8-9 fi long, inner ventral 5.4 jx long, outer ventral 7.2 fj. long ; anal ring with 6 

 setae 24 and 27 m long, and with an inner row of 6 and an outer row of 12 pores, 

 divided on dorsal side and tending toward division on ventral. 



Larva. — Elongate, posterior end narrowed. 



Margin: With 26 8-shaped pores (a pair missing immediately anterior to 

 anterior spiracles), the posterior pair a little larger than the penultimate pair, 

 the latter slightly larger than the next 4, the next 6 about the same size as the 

 penultimate, and the anterior pair the largest of all, axes of all pores longitudinal ; 

 3 pairs of setae anteriorly. 



Dorsal surface : 8-shaped pores in a submedian row of 4-6 on each half of body, 

 the anterior pore in each row the largest, all very slightly smaller than marginal 

 pores of same segments ; disk pores present in submarginal area and a few in 

 lateral area. 



Ventral surface : Antennal setae, I, 1 ; IV, 1 ; V, ; VI, 2 long, 2 stout, 3 fairly 

 stout, 1 slender ; antennal bases one-third length of antenna apart ; beak setae, 

 2 pairs apical, 1 pair basal ; spiracle with 1 trilocular and 1 quinquelocular pore ; 

 leg setae, coxa 4, femur 1 on inner margin near base and 1 each on inner and 

 outer margins near center, tarsus 2 on inner and 1 on outer margin ; tibia nearly 

 one-half as long as tarsus ; 9 pairs of submarginal 8-shaped pores ; 8 pairs of 

 submarginal minute setae posterior to anterior spiracles, 2 pairs of submarginal 

 larger setae at anterior end ; 1 pair of setae between antennae and mouth parts. 



Apex of abdomen : Notch narrow ; setae, apical 52 fi long, interapical 12 n long, 

 inner ventral 2 /* long, outer ventral 3.6 /j. long ; anal ring with 6 setae 3.6 m long. 



Data. — Described from unmounted material, five mounted females, 

 and five mounted larvae on Arundinaria sinica, Hong Kong, China, 

 A. S. Hitchcock, November 5, 1921, U. S. N. H., holotype and para- 

 types. 



This species is closely related to oblongum. 



Asterolecanium longum (Green) 



(Fig. 36, A-E; pi. 3, B) 



Described in 1896 (40, p. 5) as Planohonia miliaria longa. Re- 

 described by Green in 1909 (1$, pp. 336-337) as Asterolecanium lineare. 

 In 1909 (1$, in a note inserted in the volume) Green proposed the name 

 lanceolatum in place of lineare, which was preoccupied by lineare 

 Lindinger. Although Green stated in 1909 {1$, pp. 336, 339) that the 

 variety described in 1896 contained a distinct species and variety, all 

 specimens described as miliaria longa in 1896 apparently belonged to 

 the species later designated as lineare and laneeolatum: Since longum 

 is the older name, it is the valid name of the species, and lineare Green 

 and lanceolatum are synonyms of it.
