THE SCALE INSECT GENUS ASTEROLECANIUM 207 



Ventral surface: Antenna thimble-shaped, with 3 (broken i setae; 2 quinque- 

 locular pores between antenna and margin ; beak setae, apparently 2 pairs apical 

 and 1 pair median; spiracle with bar broad, atrium slightly enlarged and con- 

 taining 3-7 quinquelocular pores, 31-40 similar pores extending from spiracle 

 to body margin in an irregularly single or double row; multilocular pores, total- 

 ing 157 and with 7-12 (usually 10) loculi, apparently in 6 complete rows (anterior 

 row possibly interrupted), posterior and penultimate rows each with 30. each 

 of next 2 with 34, next with 13, and anterior row with 6 ; 4 dark-rimmed 8-shaped 

 pores each side of beak, a few scattered elsewhere, possibly tending toward 

 arrangement in transverse rows posterior to mouth parts ; submarginal 8-shaped 

 pores in a single row terminating near posterior row of multilocular pores, about 

 one-third as numerous as corresponding marginal 8-shaped pores of nearer row ; 

 submarginal setae in a complete row terminating slightly farther posteriorly than 

 the marginal 8-shaped pores, much more numerous than usual, 34 occurring be- 

 hind posterior spiracles: 1 pair of setae in each of the posterior 4 rows of 

 multilocular pores. 



Apex of abdomen: In poor position for study. Notch present; lobes indicated; 

 setae, apical broken, at least 63 fx long, interapical broken, dorsal 12.6 fx. long, 

 intermediate ventral apparently 5.4 n long, outer ventral 18 u long; anal ring 

 with 6 setae apparently 36 /x long, with an inner row of apparently 6 and an outer 

 row of an indeterminable number of pores, divided on dorsal and ventral sides ; 

 ventral surface of apex slightly sclerotized and slightly reticulate. 



Data. — Redescribed from one test and one mounted female on 

 Quereus (Pasania) henryi, Tuk Shan, Kweichow, China, Y. Tsiang, 

 August 22. 1930, N. Y. B. G. 



Assigned to tokyonis on the basis of the original description. In 

 the specimen examined there are many small, conspicuous dorsal 

 8-shaped pores which were not mentioned by Kuwana, and two pairs 

 of setae in the anal area in addition to those included in the original 

 description. 



Asterolecanium townsendi Cockerell 



(Fig. 72, A-K; pi. 3. H) 



Described in 1902 (25, pp. 468-4*69). 



Habit. — Living on bark, sometimes in shallow pits. 



Test of female. — Broadly ovoid or nearly circular, posterior end slightly pro- 

 duced and slightly or distinctly elevated ; 2.5 mm. long, 2.25 wide, or 2-2.5 mm. 

 in diameter: convex dorsally, sloping to posterior tip, sometimes with a faint 

 longitudinal median carina near posterior end ; presumably flat or very slightly 

 convex ventrally ; brownish or clear yellow, transparent, rather thick, shiny, 

 punctate: marginal filaments whitish, fragmentary; dorsal filaments rubbed off; 

 elliptical larval exit in margin. 



Adult female. — Nearly circular, posterior end slightly produced ; around 2.25 

 mm. in diameter. 



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

 length (less than one-half length of an apical seta) from bases of setae, 12 fi 

 long and 8 wide, usually a pore's width apart : quinquelocular pores in a row that 

 is single posteriorly and irregularly so anteriorly but double on the middle por- 

 tion, terminating at or near the posterior pair of 8-shaped pores, quinquelocular 

 pores as numerous as 8-shaped pores at posterior end of row. nearly twice as 

 numerous on remainder of posterior fourth and on the anterior fourth, and up 

 to four times as numerous as corresponding 8-shaped pores on middle portion : disk 

 pores among 8-shaped pores and terminating with 1 posterior to the last 8-shaped 

 pore. 1 near each 8-shaped pore near end of row, and 1 near every other 8-shaped 

 pore elsewhere. 



Dorsal surface: 8-shaped pores with a tendency toward a Longitudinal grouping 

 in median area and occurring in transverse rows elsewhere, majority 14-16 a 

 long and 1(1-12 wide, many 20 u long and 14 wide; minute 8-shaped port's absent : 

 disk pores fairly numerous; tubular ducts 36 /u long. 



Ventral surface: Antenna dome-shaped, sunken in derm, with 2 setae longer 

 and 2 slightly shorter than diameter of antenna; 5 or 6 quinquelocular pores 

 between antenna and margin; beak with 2 pairs of setae: spiracular bar fairly
