THE SCALE INSECT GENUS ASTEROLECANIUM ] 1 3 



Ventral surface: Antenna sclerotized. roughly circular, flat, sunken in derm, 

 with 2 setae slightly longer than diameter of antenna; beak with 1 pair of 

 setae; spiracle with bar fairly wide and slightly expanded at inner end. atrium 

 enlarged, bag-shaped, and containing 6-9 quinquelocular pores, &-12 similar | 

 extending from spiracle to body margin in a single row: multilocular pores with 

 6-10 loculi and arranged in 2 complete and apparently 2-5 interrupted rows, 

 each of complete rows with 6-9 pores and each of interrupted rows with 2; 

 2_4 dark-rimmed 8-shaped pores each side of beak, a few scattered in lateral 

 area of abdomen, and 4 or 5 tending toward arrangement in a transverse row 

 anterior to multilocular pores; submarginal 8-shaped pores in a single row 

 terminating near the posterior row of multilocular pores, approximately one- 

 third as numerous as marginal 8-shaped pores: submarginal setae in a complete 

 row usually terminating 3 8-shaped pores from the posterior pair of marginal 

 8-shaped pores; 2 pairs of setae in the posterior row of multilocular pores, 1 pair 

 in the anterior complete row, 1 pair in the posterior interrupted row. and some- 

 times: 1 pair in the next interrupted row. 



Apex of abdomen; Notch minute: lobes indicated, on ventral surface close to 

 margin ; setae, apical 52 ix long, outer ventral about 4 u long: anal opening ven- 

 tral, close to body margin, circular, its margin membranous. 



Larva. — EMiptical. 



Margin: With 28 8-shaped pores, axes of all longitudinal; a pair of minute 

 setae close to each of the posterior 3 pairs of pores : 3 pairs of setae at anterior 

 end. 



Dorsal surface: One 8-shaped pore on median line, and 3 in a lateral row on 

 each half of body, the median pore as large as. or slightly larger than, lateral 

 pores, all alv ut two-thirds the *ize of inargmal pores: disk pores in lateral area. 



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

 stout, 2 fairly stout: antennal liases two-thirds length of antenna apart; beak 

 setae, at least 1 pair near tip. and 1 pair near base: spiracle with 1 trilocular 

 and 1 quinquelocular pore ; leg setae, coxa apparently 2. femur 1 on inner margin 

 near base, tarsus apparently 1 each on inner and outer margins: tibia one-half 

 as long as tarsus; 9 pairs of submarginal 8-shaped pores; 9 pairs of submarginal 

 minute setae, on abdomen, thorax, and head ; 2 pairs of setae between antennae 

 and mouth parts. 



Apex of abdomen : Notch present : lobes indicated ; setae, apical 36 n long, 

 interap.cal apparently 1.8 m long, outer ventral 2 /x long; anal opening in margin, 

 circular, its margin slightly sclerotized. 



Data. — Described from unmounted material, five mounted females, 

 and six larvae on Palmae (Chaanaedorea sp.?), Cordoba. Mexico. O. F. 

 Cook, U. S. X. H.. holotype and paratypes. 



This species can be separated from other species on palm by the 

 uninterrupted row of marginal 8-shaped pores which extends across 

 the apex of the abdomen, by the presence of two groups of la rue 

 8-shaped pores near the anterior end of the body, and by the even dis- 

 tribution of many smaller 8-shaped pores posterior to the large pores. 



Asterolecanium inusitatum, new species 



(Fig. 33, G-M; fig. 34, A, B; pi. 8, L) 



Habit. — Living on the upper surface of leaves. 



Test of female. — Elongate ovoid. 1.4 mm. long. 0.75 wide, posterior third 

 strongly tapered; mostly convex dorsally hut posterior tip nearly ilat. with a 

 faint longitudinal median carina : slightly convex ventrally: clear yellow, trans- 

 parent, shiny, punctate; marginal filaments rubbed oh': dorsal filaments clear 

 yellow, scattered, varying in length: circular larval exit in dorsal surface at 

 margin. 



Adult female. — Elongate ovoid, posterior end strongly tapered; 1.2 nun. long, 

 0.5 wide. 



Margin: 8-shaped pores in a single row terminating about twice length of 

 apical seta from seta! bases, posterior pores 8 ft long and 4 wide, others ".» .. 

 long and 4 wide, twice a pore's length apart at posterior end of row. a pore's 

 width to length apart elsewhere: quinquelocular pores in a single row tenni
