nraltilocolar pores, nearly as numerous as marginal 8-shaped pores; 

 snbmarginal setae on abdomen, the posterior pair near the penultimate pair of 

 marginal 8-shaped pores: 1 pair of setae in each of the posterior 3 r< 

 multilobular pores. 



Apex of abdomen : Setae, apical 21-25 y. long, interapieal 8 ,u long, ouu r ventral 

 5.2 ft long: anal ring with G setae, each about 32 a long, and with an inner 

 row of 6 and an outer row of 16 pores, apparently not divided. 



Larva. — Nearly elongate elliptical, posterior end narrowed. 



Margin: With 2S 8-shaped pores, the posterior 6 pairs slightly smaller than 

 the others, which increase slightly in size from the sixth to the anterior pair, 

 axis of each of the posterior 6 pairs transverse, axis of each of the others 

 longitudinal; 3 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of S-10 and a lateral row 

 of 3-5, on each half of body, a total of 24-20. posterii r pores of each row very 

 slightly smaller than anterior pores, all except anterior pore of submedian row, 

 which' is slightly larger than anterior marginal pore, one-fourth smaller than 

 marginal pores of same segments : disk pores in a single row between lateral and 

 marginal, and a few between lateral and submedian 8-shaped pores. 



Ventral surface: Antennal setae. I. 1: IV. 1 : V. 0: VI. 2 long. 2 stout, 3 fairly 

 stout. 1 slender: bases of antennae one-half length of antenna apart: beak - 

 2 pairs apical. 1 pair median: spiracle with 1 trilocular pore; leg setae, coxa 4. 

 femur 1 on inner margin near base and 1 on outer margin near center, tarsus 



2 on inner and 1 on outer margin; tibia one-half length of tarsus: 9 pairs of 

 submarginal 8-shaped pores: 6 pairs of snbmarginal minute setae on abdomen, 



3 pairs of submarginal larger setae at anterior end: 1 pair of setae between 

 antennae and mouth parts. 



Apex of abdomen : Setae, apical 50 \x long, interapieal 10.8 n long, outer 

 ventral 2.5 u long : anal ring with 6 setae, each about 12.6 /j. long, and with an 

 inner row of 6 and an outer of apparently 10 pores, apparently not divided. 



Data. — Described from unmounted specimen? (paratypes) and 

 the following mounted specimens (host material collected by F. A. 

 McClure in China) : One female on Arumdinaria amabilis, Yung Hui. 

 Kwangsi. November 12. 1925. paratype: three females and three larvae 

 on Arundmaria amabUis, Koo Shui. Kwong Ning district. Kwang- 

 tung. March 24. 1929. holotype and paratypes: two females on Aru,n- 

 dinaria sp., Naam Fung to Xodoa. Hainan. Kwangtung. August 29, 

 1929. paratypes: one female on Anmdinaria sp.. between Yan Ping 

 and Yeung Kong. Kwangtung. December 15. 1931, paratype. 



Closely related to masuii and sa^ae. but having dorsal 8-shaped pores, 

 which are not found in masuii, and having more marginal quinque- 

 locular pores than occur in sasae. The larvae differ from those of 

 masuii and sasae in having only one seta on the inner margin of the 

 femur. 



Asterolecanium fusum, new species 



(Fig. 26, A-D; pi. 9, P) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Longer than wide, posterior end slightly produced: 1.4 mm. 

 long, 1 wide: slightly convex dorsally, with a faint longitudinal median carina. 

 flat ventrally ; yellow, transparent, rather thick: marginal filaments rubbed off; 

 larval exit a slit in margin. 



Adult female. — Similar to test in shape. 1.25 mm. long. O.So wide. 



Margin: 8-shaped pores in a single row terminating about the Length of apical 

 seta fin m bases of setae, posterior pores 8 u long and 5 wide, the others 10 - 

 long and 6 wide, about a pore's width apart: qoinquelocular pores in a simile 

 row terminating at. or posterior to. the posterior pair of 8-shaped pores, usually 

 1 near each 8-shaped pore; disk pores dorsad of 8-shapvd pores, terminating 

 between the posterior pair of 8-shaped pores and apical setae, usually l near 

 every fourth 8-shaped pore at anterior end. and somewhat more numerous 

 elsewhere. 



I >< real snrface: Minute 8-shaped pores rather sparse; disk pores very sparse: 

 tubular ducts 27 m long: dorsal tubes present.
