THE SCALE INSECT GENUS ASTEROLECANTUM 07 



marginal setae on abdomen, the posterior pair around length of apical seta from 

 bases of apical setae; 1 pair of setae posterior to genital opening, 1 pair anterior 

 to opening, and 1 pair anterior to those. 



Apex of abdomen : Notch present ; setae, apical 38-44 n long, interapical 4-5.4 

 fi long, intermediate ventral 3-5.4 /* long, outer ventral 4.6-5.4 /u. long; anal ring 

 with 6 setae, each about 24 fi long, also with an inner row of 6 and an outer 

 row of 12 pores ; ventral surface of apex slightly sclerotized in dentate rows 

 or sclerotized and rugose. 



Larva. — Nearly elliptical. 



Margin : With 28 rather elongate, slender 8-shaped pores, the posterior 2 pairs 

 of pores slightly larger than those adjacent, next 4 pairs uniform in size, the 

 others gradually increasing in size to anterior pair, which is slightly larger than 

 posterior pair ; axes of the posterior 6 pairs strongly diagonal or actually 

 transverse, the others longitudinal ; apparently 3 pairs of setae anteriorly. 



Dorsal surface : 8-shaped pores, totaling 13-15, in a submedian row of 6-8 

 on each half of body, about one-half the size of a posterior marginal 8-shaped 

 pore ; disk pores in lateral area and a few in submarginal area. 



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

 fairly stout, 1 slender ; bases of antennae about one-half length of antenna 

 apart; beak setae, 2 pairs apical, 1 pair median; anterior spiracle with 1 tri- 

 locular, posterior with 1 trilocular and 1 quinquelocular 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 ; 7 pairs of submarginal minute 

 setae, on abdomen and thorax, 3 pairs of submarginal larger setae at anterior 

 end ; 1 pair of setae between antennae and mouth parts. 



Apex of abdomen : Setae, apical 36-42 fi long, interapical 3.6 n long, inter- 

 mediate ventral (rather close to median line) 3.6 n long, outer ventral 3.6 fx 

 long ; anal ring with 6 setae, each about 5.2 fi long.

Rather closely related to par cum. but having marginal 8-shaped pores 

 close together and tubular ducts 28 instead of 12 /x long. Closely re- 

 lated to radiatum, but with many marginal quinquelocular pores, 

 while radiatum has none. 



Asterolecanium coffeae Newstead 



(Fig. 15, A-K; pi. 4, C) 



Described in 1911 (76, pp. 161-102) on Coffea arabica from Dutch 

 East Africa. 



Habit. — Living on bark. 



Test of female. — Elongate ovoid or broadly ovoid, posterior end slightly pro- 

 duced and often sligbtly upturned; 1.5 mm. long, 1-1.25 wide; convex dorsally.
