Females of this species show more than the ordinary amount of 

 variation both in arrangement and number of multilocular pores. The 

 same condition is found in stentae. a species closely related to arabidis, 

 and to a less marked extent, probably owing to the few specimens 

 studied, in other closely related forms such as launeae and fmhriatv.m. 



ASTEROLECAXIUM BAMBUSAE (Boisdtival) 



(Fig. G. J-O; fig. 7. A-G ; pi. 2. F, G I 



Described by Boisduval in 1869. as Chermes bambusae, on Bambusa 

 arundinacea and distorta from the garden of Hamma. Alger. Algeria 

 (9. pp. 201-202) : redescribed by Signoret in 1870 (88, pp. 280-281). 

 Signoret indirectly disclosed the source of his material of bambusae 

 in the following statement contained in his description of mttiaris, 

 which follows that of bambuscu : "Cette espece. comme la precedente. 

 se trouve en quant ite quelquefois considerable sur les divers bambous 

 des Indes, Bambusa distorta, arwndinaeea, strieta, et elle nous a etc 

 donnee par M. Boisduval et par M. Riviere, qui nous en a fait venir 

 obligeamment du Jardin d'Acclimatation du Hamma (Algerie)." 

 Thus it is reasonable to assume that his specimens of bambusae were 

 received from Boisduval or Riviere, and as such represent type 

 material. 



Type specimens of bambusae var. bcumbusulae, described by Cock- 

 erel! in lb97 (20, p. -500). on bamboo from Grenada, are identical with 

 bambusae; consequently the varietal name is suppressed. 



Habit. — Living on stems and both sunaces of leaves. 



Test of female. — Usually distinctly longer than wide, somewhat ovoid, pos- 

 terior end slightly produced and often upturned; 1.5-3.5 mm. long, 1 2.5 wide: 

 slightly to rather strongly convex dorsally. sometimes with a faint longitudinal 

 median carina near posterior end. flat ventrally; greenish, brownish, or pale 

 yellow, transparent, thin, shiny: marginal and dorsal filaments whitish to pale 

 pinkish, a few of the latter along median line, and sometimes in submedian, 

 lateral, or submarginal area: larval exit narrow elliptical, in margin. 



Adult female. — Broadly ovoid to elliptical, 1.25-3.25 mm. long. 0.75 J/J.") wide. 



Margin: 8-shaped pores in a single row terminating two or three times a pore's 

 length from bases of apical setae, posterior pores 8-9 p long and 4 wide, others 

 around 12 u long and 5 wide, spaces he; ween pores ranging from the width to 

 the length of a pore: quinqueloeular pores in a single row terminating at the 

 posterior pair of 8-shaped pores or 1-16 (usually 1 3) 8-shaped pores from that 

 pair, rarely interrupted at anterior end for 4 12 8-shaped pores, usually one 

 a half ;imes as numerous as 8-shaped pores hut occasionally not more numerous, 

 particularly at anterior end; disk pores dorsad of 8-shaped pores, terminating
