THE SCALE INSECT GENUS ASTBROLECANIUM ] ] 9 



Apex of abdomen: Apparently with a very shallow notch; s< itae, apical 

 long, interapical 10-12 u long, outer ventral 8 n long; anal ring with 6 » 



each about 44 /x long, and with an inner row of 6 and an outer row of 2l 



Data. — Described from the following material : One mounted female 

 on bamboo. China, intercepted at San Francisco, Calif., A. C. Dennett, 

 November 25, 1936, paratype; one tesi preserved in balsam and 



mounted female on bamboo, China, intercepted at New York, S. D. 

 Whitlock, June 8. 1937. holotype. 



The paratype specimen of this species is partially covered with 

 fungus, and the holotype specimen is somewhat torn and mutilated on 

 the abdomen, consequently it is impossible to determine the exact 

 position and number of multilobular pores and a few other detail-. 

 This species differs strongly from most other species on bamboo in 

 size, and is the longest species known, the observed test being 4 mm. 

 long, or 0.5 mm. longer than any observed tests of bambusicola. It 

 resembles masuii most closely but differs from it in having a large 

 number of dorsal 8-shaped pores, as well as in many less conspicuous 

 characters. 



Asterolecanium launeae, new species 



(Fig. 37, A-G; pi. 1, E) 



Tidbit. — Living on stems, in shallow depressions. 



Test of female. — Usually slightly lunger than wide, sometimes nearly circular 

 or slightly wider than long, posterior end very slightly produced and sometimes 

 slightly elevated : usually 2 mm. long, 15 wide, but a few specimens 2 mm. long, 

 2-2.5 wide: slightly to rather strongly convex dorsally, nearly flat to somewhat 

 convex ventrally : yellow, translucent, rather thick, smooth, sometimes shiny; 

 marginal and dorsal filaments whitish, or nearly colorless and glassy, a few 

 broken dorsal filaments in 2 or 3 tufts on median line in center of test and a few 

 scattered elsewhere in some specimens : elliptical larval exit in margin. 



Adult female. — Similar to test in shape. 1.5-2 mm. long, 1.10-1.5 vide. 



Margin : 8-shaped pores in an irregularly double row terminating twice to 

 three times a pore's length from bases of apical setae, the row single on part of 

 margin, but distinctly double either in spots or along most of margin, individual 

 pores measuring 13-14 u long and S wide, usually around a pore's length apart, the 

 2 rows less than a pore's width apart: quinquelocular pores usually in a single 

 row between and outside spiracular pore bands, usually not mere than 4 pores 

 anterior to anterior spiracular pore band and 10 posterior to posterior spiracular 

 pore band, the row sometimes interrupted between the pore bands, and the pores 

 usually no more numerous than 8-shaped pores of nearer row ; disk pores irregularly 

 spaced, dorsad of 8-shaped pores and around one-third as numerous as these, 

 terminating near the posterior pair of 8-shaped pores: disk pores also ventrad 

 of quinquelocular pores, terminating near the posterior pair of 8-shaped pores. 

 very irregularly spaced and much less numerous than 8-shaped pores. 



Dorsal surface: 8-shaped pores usually in 3 or 4 groups in median area, each 

 group usually with 2-6 pores, the total number being about 20. but sometimes 

 with pores strewn sparsely over entire surface, median pores 13-14 ,u long and 

 8 wide, the other pores, which have a tendency toward arrangement in indefinite 

 transverse rows, usually 11-12 u long and 7 wide, but a few 14 a long and 8 wide. 

 or 8 ,u long and 7 wide : minute 8-shaped pores fairly numerous ; disk pores numer- 

 ous : tubular ducts 44 u long. 



Ventral surface: Antenna a roughly circular area with 2 setae longer and 

 3-0 shorter than diameter of antenna: beak with 2 pairs oi setae; spiracle with 

 bar broad, often subcircular, with a sclerotized band extending around opening. 

 sclerotized area with 3-6 quinquelocular pores and with similar pores extending 

 to body margin in an irregularly double or triple row. 25-48 pores in group and 

 row combined; multilocular pores, with 7-10 loculi. in 3 complete rows, or in 2 

 complete rows and 1 interrupted row. the posterior row with 5 13, middle row 

 with 7-14. anterior row with 2 0. the total ranging from 14 20; 2 dark-rimmed 

 8-shaped pores each side of beak, a few scattered on anterior end. and others 

 arranged in 5 or 6 transverse rows on abdomen: submarginal 8-shaped pores in
