Data. — Redescribed from the following material: Unmounted ma- 

 terial and 12 mounted females on bamboo, Royal Botanic Gardens, 

 Peradeniya, Ceylon, R. S. Woglum collector, October 1910. Un- 

 mounted material, 7 mounted females, 3 mounted second- stage speci- 

 mens, and 5 mounted larvae on Bambusa sp., Mauritius, De Charmoy 

 collector, from E. E. Green, type material of charmoy i. Unmounted 

 material, 15 mounted females, and 8 mounted larvae on Bambusa sp., 

 Nisui, Taiwan (Formosa), R. Takahashi collector, April 19, 1929, 

 same collection data as type material of pseud omiliaris var. bambusi- 

 foliae. A mass of unmounted material, 125 mounted females, and 20 

 mounted larvae on Arundinaria glaucescens, Arundinaria sp., Bambusa 

 arwidinacea, B. balcooa, B. noma, B. pallescens, B. spinosa, B. tulda, 

 B. tuldoides, B. vulgaris, B. vulgaris var. aureo-variegata, Bambusa 

 sp., and Dendrocalamus strictus, the localities involved being Chicago, 

 111. (in greenhouse); San Salvador, El Salvador; Cuba; Jamaica; 

 Puerto Rico; Grenada; Tobago; Antigua; St. Kitts; Trinidad; Brit- 

 ish Guiana; near Caracas, Venezeuela; States of Minas Geraes and 

 Rio de Janeiro, Brazil; Alger, Algeria; Amani, Tanganyika; Assam 

 and Calcutta, India; Peradeniya, Ceylon; Kwangtung, Kwangsi, and 

 Fukien, China ; and Japan. 



Allied to caudatum and miliwis. The ventral simple pores men- 

 tioned and illustrated by Green (4>6, pp. 1036-1037) probably are the 

 ventral submarginal 8-shaped pores rather than the marginal quin- 

 quelocular pores. 



ASTEROLECANIUM PSYCHOTRIAE, DOW species 



(Fig. 55, A-E; pi. 4, J) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Slightly longer than wide, around 1.75 mm. long and 1.5 

 wide ; flat or slightly convex dorsally ; flat ventrally ; pale greenish yellow, 

 transparent, thin, punctate- marginal filaments pale greenish yellow to very 

 pale salmon ; dorsal filaments whitish, pale greenish yellow, or pale salmon, 

 some longer and some shorter than marginal filaments, occurring along median 

 line and in submedian and submarginal groups ; elliptical larval exit in margin. 



Adult female. — Longer than wide, around 1.3 mm. long, 0.9 wide. 



Margin: 8-shaped pores in a single row terminating around twice a pore's 

 length from bases of apical setae, posterior pores around 12 n long and 8 wide, 

 others about 14 fi long and 8 wide, less than a pore's width apart ; quinquelocular 

 pores in a single row terminating with 2 pores posterior to the posterior pair of 

 8-shaped pores, as numerous as corresponding 8-shaped pores toward posterior 

 end of row, somewhat more numerous elsewhere. 



Dorsal surface : 8-shaped pores arranged roughly in median, submedian, and 

 submarginal groups, with submedian and submarginal groups sometimes merg- 

 ing ; median group divided into 9 or 10 transverse groups, of which the posterior 

 one has 1 or 2 pores, the penultimate one 3 (where 10 groups occur), and each of 

 the others 5-9; 3 definite submarginal groups and 3-6 fairly definite submedian 

 groups on each half of body, 3-11 pores in each of submarginal groups, and 1-7 

 in each of submedian ; the total number of pores on dorsal surface ranging from 

 122-144 in the specimens examined ; majority of median and some of submedian 

 and submarginal pores 14 /x long and 9 wide, a few median and the majority 

 of submedian pores 12 /x long and 8 wide, 1 or 2 outer pores of submarginal 

 groups usually 20 n long and 12 wide ; minute 8-shaped pores fairly numerous ; 

 disk pores rather sparse ; tubular ducts 24 /* long. 



Ventral surface: Antenna conical, sunken in derm, with 1 (possibly 2) seta 

 shorter than, and 2 about same length as, diameter of antenna ; 3 or 4 quinque- 

 locular pores between antenna and margin ; beak with 2 pairs of setae ; spiracular 

 bar subcircular, 24 n wide; shallow furrows around spiracular opening containing 

 2 or 3 quinquelocular pores and 10-17 similar pores extending to body margin 

 in a single or double row ; legs represented by a single pair of small, rather in-
