narrow band ar opening, not distinctly enlarged in middle as in female, very 

 slightly smaller at ring than at opening, nearly cylindrical, anal ring with 6 

 setae 2o u long and with an indeterminable number of pores, apparently not 

 divided, ventral surface of apex apparently not rugose. 



Data. — Described from unmounted specimens (paratypes) and the 

 following mounted specimens from Hainan Island. Kwangtung, China : 

 Four females, five larvae, one adult male, one male nymph, and one 

 third-stage male from Bambusa sp., Kachek. A. S. Hitchcock. October 

 13. 1921, U. S. X. H..holotype and paratypes; one female from SgMbo- 

 stachyum sp.. Hau Laan. F. A. McClure, 1929. paratype: one female 

 from Schizostachyum sp.. Faan Maan Ts'uen. Ling Shui district. F. A. 

 McClure. May 8, 1932. paratype. 



Asterolecanium pusUlwm is unusual in having one pair of setae on 

 the apex of the abdomen in the adult female, two pairs in the third- 

 stafre male, and three pairs in the larva. It is more closely allied to 

 exigwrn. rttbrocomatum^ and udagamae than to other known species. 



Asterolecanium pustulans (Cockerell) 



(Fig. 56. A-E; pi. 4. F) 



Described by Cockerell in 1892 (7J. pp. llft-lltf) as Asterodiaspis 

 pustulans and redescribed by him in 1893 (17\ pp. 77-78) as Planchonia 

 pustulans. 



Asterolecanium pustulans sambuci, described by Cockerell in 1903 

 ( ;'/. p. 112). from material on Sambucus sp. from Cairo. Egypt, is 

 here synonymized with pustulans. No varietal differences have been 

 found between the two. the characters considered by Cockerell (26. p. 

 112) and Hall (SO, pp. j-J) fitting typical pustulans as well as speci- 

 mens named pustulous sambuci. A . pustulans seyeheUarwm also is here 

 placed as a synonym of pustulans. Green described this variety on 

 Hewea brasiliensis from the Seychelle Islands in 1910 (48, pp. 3-5) 

 and stated. ''The variety under consideration differs from the type 

 merely in superficial characters of the secretionary covering." In the 

 writer's opinion neither the tests nor the morphological structures of 

 type specimens of pustulans seychellarwn exhibit differences, as com- 

 pared with typical specimens of pustulans, that justify varietal 

 distinction. 



Habit. — Living on bark, leaves, and fruit, on smooth surfaces or in shallow 

 or deep pits. 



Test of female. — Practically circular to ovoid, posterior end sometimes slightly 

 produced: 1-1.86 mm. in diameter, or 1.25-2 mm. long and 1—1.65 wide: nearly 

 flat to fairly convex dorsally, usually with a faint longitudinal median carina and 

 faint transverse striatums; flat to convex ventrally: brownish or greenish yellow, 

 transparent, punctate: marginal and dorsal filaments whitish to pinkish, some 

 dorsal filaments longer and others shorter than marginal ones; elliptical larval 

 exit in margin. 



Adult f< male. — Nearly circular or ovoid. p<»>r,.ri ( .r end slightly produced : 0.9 1.6 

 mm. in diameter, or 1-1.75 mm. long, and 0.9-1.5 wide. 



Margin : 8-shaped pores in a single row terminating one-third t<> two-thirds length 

 of an apical seta from bases of setae, often somewhat crowded near antevi 

 and some pores out of alignment, posterior pore- 11 1:! u long and 7 wide, others 

 12 m Ion- and 8 wide, usually about a pore's width apart : quinquelocnlar | 

 in a single row terminating near the posterior or penultimate pair of 8-shaped 

 pores, or with 1 pore beyond the end of the row of those pore-. 1 quinquelocnlar 

 to each 8-shaped pore near posterior end of row and often nearly to posterior 

 spiracular pore bands, elsewhere usually 1 quinquelocnlar to each 8-shaped pore
