enlarged, shallow, and containing 2 or 3 quinquelocular pores, and with 8-15 

 quinquelocular pores extending to body margin in an irregularly single or double 

 row ; 1 or 2 dark-rimmed 8-shaped pores each side of beak, a few scattered on 

 anterior end, and others in a lateral row on abdomen and in 2 sparse transverse 

 rows anterior to genital opening; submarginal 8-shaped pores in a single row 

 terminating opposite genital opening, usually half as numerous as marginal 

 8-shaped pores ; 6 pairs of submarginal setae on abdomen, the posterior pair 

 slightly nearer to the posterior pair of marginal 8-shaped pores than to bases of 

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

 and 1 pair anterior to those. 



Apex of abdomen : Notch present ; lobes barely indicated ; setae, apical about 

 56 fi long, interapical about 6.5 y. long, outer ventral 4-5 fi long ; anal ring with 

 6 setae 24-27 n long, with an inner row of 6 and an outer row of 12 pores, tending 

 toward division on dorsal side ; ventral surface of apex rugose. 



Data. — Described from parasitized unmounted material, one intact 

 mounted female, and half of another, on Bambusa atra, Amboina, 

 Moluccas Islands, C. B. Robinson, July-November 1913, U. S. N. H., 

 holotype and paratypes. 



Most closely related to captioswm, from which it differs most con- 

 spicuously in having dorsal 8-shaped pores.

ASTEROLECANIUM ARABIDIS (Signoret) 



(Fig. 0, A-Ij pi. 2, E, H) 



Described by Signoret in 1876 (89, p. 60S) as Planchonia arabidis, 

 from specimens received from Lichtenstein. Although Signoret listed 

 the species as "Planchonia arabidis Licht, mss.," there is no indication 

 that Lichtenstein was responsible for any part of the description. 

 Consequently the species is credited to Signoret. 



Four names are here suppressed as synonyms of arabidis. Plan- 

 chonia hederae, described by Lichtenstein in 1880 (58, pp. xlv-xlm) 

 on Hedera helix from Montpellier, is placed as a synonym because 

 specimens presumed to be type material of hederae are specifically 

 identical with arabidis. In 1882 (59, p. Ixxv) Lichtenstein gave the 

 name Planchonia valloti to specimens which he had not seen, that had 

 been described briefly, but not named, by Vallot, in 1838 (99, pp. 50-51). 

 Although Vallot's material, found on ivy at Dijon, or other material 

 from this source, is not available, it seems likely that his specimens 

 belonged to arabidis, the species found commonly on ivy in Europe. 

 Vallot did not indicate whether he removed any insects from the ivy, 

 and the specimens treated by him and Lichtenstein probably are not 

 extant. The name valloti was listed as a synonym of hederae by 

 Fernald in 1903 (32, p. 51) and of fimbriatum by Lindinger in 1912 

 (61, p. 375). 



A. massalongianum was described by Targioni-Tozzetti in 1892 

 (98, pp. 295-298, 312) on Hedera from Italy. Type material of the 

 species is not available, but other specimens on Hedera from Italy 

 represent arabidis. Moreover, from the original description of mas- 

 salongianum it seems certain that this name is synonymous with 

 arabidis. It was given as a synonym of hederae by Fernald in 1903 

 (32, p. 51), and as a synonym of fimbriattcm by Lindinger in 1912 (61, 

 p. 175) and by Leonardi in 1920 (57, p. 21*1). 



In 1893 Douglas described Pollinia thesii, on Thesium hwrnijusum 

 from the Isle of Purbeck (29, pp. 55S7) . A mounted specimen from 

 type material of thesii is the same as arabidis, and as a consequence the
