THE SCALE INSECT GENUS ASTEROLECANIUM J I] 



8-shaped pore near posterior end, elsewhere 1 opposite each 8-shaped pore and 

 1 opposite nearly every interval between 8-shaped pores; dorsal surface without 

 large 8-shaped pores: ventral surface with bar of spiracle narrow, atrium with 



1 qninquelocular pore and 1 or 2 pores between spiracnlar opening and body 

 margin; apex of abdomen with setae arranged as in adult, but apical setae 

 broken, and ventral setae one-half length of corresponding setae in adult ; anal 

 ring without pores, not divided ; ventral surface of apex not rugose. 



Larva. — Elliptical. 



Margin : With 28 8-shaped pores, the posterior 6 pairs slightly larger than 

 the next 7, and the anterior pair largest, axes of the posterior 6 pairs transverse, 

 of the others longitudinal ; 1 pair of setae anteriorly. 



Dorsal surface: 8-shaped pores in a submedian row of 10 and a lateral of 6, 

 on each half of the body, the posterior 4 submedian pores slightly smaller than 

 marginal pores of same segments, next 4 practically same size as the latter, 

 and the anterior 2 pores slightly larger ; the posterior 4 lateral pores about 

 same size as marginal pores of same segments, the anterior 2 pores distinctly 

 larger ; disk pores near marginal, and a few between lateral and submedian 

 8-shaped pores. 



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

 fairly stout, 1 slender; bases of antennae one-third length of antenna apart; 

 beak very sharply pointed, with 2 pairs of setae at tip and 1 pair in median area ; 

 spiracle with 1 trilocular and 1 qninquelocular pore ; leg setae, coxa 4, femur 1 

 on inner margin near base and 1 each on inner and outer margins 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 submarginal minute setae on abdomen, 



2 pairs of submarginal larger setae anteriorly ; 1 pair of setae between antennae 

 and mouth parts. 



Apex of abdomen : Notch very narrow ; setae, apical 27 fi long, interapical 

 possibly absent, inner ventral apparently 1 fi long, outer ventral (possibly the 

 interapical situated en tad of apical and nearly or actually on the margin) 2 \x 

 long ; anal opening a very narrow incision in margin ; anal tube slightly sclero- 

 tized throughout, short, wider at ring than at opening; anal ring with 6 setae, 

 each approximately 1 \x long. 



Data. — RedescriBed from unmounted material and the following 

 mounted specimens: Two females, two second-stage specimens, and 

 three larvae on Bendrocalamus gigant&us, Peracleniya, Ceylon, E. E. 

 Green, January 1902, type material; five females and three larvae 

 on bamboo, Peradeniya, Ceylon, C. L. Marlatt, January 13, 1902, and 

 five females and one larva on bamboo, Royal Botanic Garden, Pera- 

 deniya, Ceylon, R. S. Woglum, October 1910. 



Green (J^, p. 327) said, "Posterior extremity without caudal setae. 

 but with two small marginal spines on each side." The larger of the 

 two small setae is considered as apical even though it is small. Green 

 did not mention the small seta on the ventral surface close to the 

 median line. Because of its position in the larva, there is some ques- 

 tion as to whether the seta here called outer ventral is correctly labeled. 

 From its position in other stages, and from the condition observed in 

 the species most closely related to coronatum^ however, it seems likely 

 that this seta does actually represent the outer ventral rather than the 

 interapical. This is the only known species of the genus in which 

 multilobular (enlarged quinquelocular) pores occur only anterior to 

 the genital opening. 



The "male puparium" described and figured by Green probably is 

 an adult female. All specimens mounted from this type of test have 

 been females, no males having been found in the material at hand. 

 Some adult females have the same shape as second-staiie specimens, 

 there being a great deal of variation in the extent to which the posterior 

 end is narrowed and produced.
