54 MISC. PUBLICATION 4 2 4, U. S. DEPT. OF AGRICULTURE 



Apex of abdomen : Notch small ; setae, apical 90 n long, interapical 5.4 n long, 

 outer ventral 3.6 fi long ; anal opening in dorsal margin ; anal tube very short, 

 faintly sclerotized; anal ring a sclerotized band. 



Adult male. — 1 mm. long. 



Head: Antenna broken (10-segmented according to Brain (12, p. Ill), formula 

 (longest to shortest), (V, VI), (III, IV, VII), (VIII), (IX), (II), (I), (X miss- 

 ing) ; antennal setae, I, 5 ; II, 4 ; III-IX, 10-15 ; basal bars diagonal ; 7 setae 

 anterior to ventral eye spots. 



Thorax : Bar between wing bases curved on anterior margin, twice as long as 

 wide, with an indication of a median longitudinal fold ; tibia nearly twice length 

 of tarsus. 



Abdomen : Four segments each with a pair of setae dorsally on lateral margin 

 and a pair in ventral lateral area ; lobes indicated, each with 1 long and 2 short 

 setae ; penis sheath with 3 or 4 pairs of long setae ventrally near base, and 

 smaller setae on each side of ventral opening. 



Data. — Kedescribed from 15 females, 20 larvae, and 1 male, all 

 mounted, from Borbonia cordata, Ceres, Cape Province, South Africa, 

 November 23, 1906, Brain No. 302, type. 



This is one of the few species without setae on the anal ring in which 

 the anal opening, anal tube, and anal ring are clearly differentiated. 

 The larvae differ from larvae of many species in lacking marginal 8- 

 shaped pores. 



Asterolecanium borneense, new species 



(Fig. 9, I-Q; pi. 9, N) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Somewhat ovoid, 1.4 mm. long, 0.85 wide, slightly convex 

 dorsally, with a faint longitudinal median carina, flat ventrally; greenish 

 yellow, transparent, thin, punctate ; marginal and dorsal filaments broken off ; 

 larval exit a slit in margin. 



Adult female. — Somewhat ovoid, 1 mm. long, 0.7 wide. 



Margin : 8-shaped pores in a single row terminating about three times the 

 length of a pore from bases of apical setae, each pore with a sclerotized projection 

 on dorsal edge, posterior pores 7-8 m long and 5 wide, others 9 fi long and 5 wide, 

 around a pore's length apart; quinquelocular pores in a single row terminating 

 at the penultimate or posterior pair of 8-shaped pores, one-fourth to one-half 

 as numerous as 8-shaped pores at ends of body, as numerous as 8-shaped pores 

 elsewhere. 



Dorsal surface : 8-shaped pores in a median row, and in 14 or 16 groups of 2-4 

 each in lateral area, about 6 /j. long and 4 wide ; minute 8-shaped pores very 

 numerous ; disk pores fairly numerous ; tubular ducts 24 //. long. 



Ventral surface: Antenna bluntly conical, with 1 seta shorter (or broken) and 

 1 longer than diameter of antenna ; beak apparently with 1 pair of setae ; spiracu- 

 lar bar fairly broad; 9 or 10 quinquelocular pores extending from spiracle to body 

 margin in a double row : multilccular pores, with 10 loculi, in 4 complete and 4 

 interrupted rows, posterior row with 8, each of next 2 rows with 10, next with 6, 

 each of interrupted rows with 2 or 3, and a total of about 44 ; 4 dark-rimmed 

 8-shaped pores each side of beak, a few scattered elsewhere, and some tending 

 toward arrangement in a longitudinal lateral row on abdomen; submarginal 

 8-shaped pores in a single row terminating near posterior row of multilocular 

 pores, nearly or quite as numerous as marginal 8-shaped pores ; submarginal 

 setae in a complete row terminating 3 8-shaped pores from the posterior pair o?f 

 marginal 8-shaped pores ; 3 setae in posterior row of multilocular pores, 2 in each 

 of other complete rows. 



Apex of abdomen : Notch small ; lobes indicated : setae, apical, tip broken, 55 n 

 long, probably no more than 60 if unbroken, interapical 5 /n long, outer ventral 

 6 /* long ; anal ring with 6 setae, each apparently at least 27 fi long, also with an 

 inner row of 6 and an outer row of apparently 12 pores, and with a very slight 

 indication of division on dorsal and ventral sides. 



Larva. — Elongate ovoid. 



Margin : With 28 8-shaped pores, axes of all longitudinal ; 2 pairs of setae 

 anteriorly.
