13. Asierolecanium miliaris. — In great quantity on stems of bamboo 

 (Hart). 



15. Pulvinaria hrassice on leaf of some orchid, \\-ith Lecanium lies-- 

 periclmn and Chionasjns hraziliensis. P. brassice has hitherto been onl^' 

 known from specimens found in an orchid in a greenhouse in Canada. 

 The present specimens differ from the original types in the marginal spines 

 being all entire, and the anal plates do not show the three large bristles on 

 outer hind margin. The antemiae and feet agree precisely with typical 

 brassice. The ovisacs are about as wide as in the typical specimens, but 

 only about 3i mm. long, being doubtless not yet fully formed. The species 

 is very closely allied to P. simulans, but seems to be distinct. 



18. Lecanium nanum, n. sp. — Female scale flat, reddish-brown or yel- 

 lowish, broad-pyriform, shiny, with more or less of a median longitudinal 

 ridge. Length 1| mm., breadth slightly over 1 mm. Antemiae seven-jointed, 

 but the joints very obscure, 3 much longest, formula apparently 3 (27) 14 

 (56). Marginal spines very small, entire, rarely shghtly branched at end, 

 pointed. Anal plates short and broad, red-brown. Derm with small scat- 

 tered round gland-dots. The general color of the females after boihng in 

 soda is brown, the contained embryos being pink, Eostral loop extending 

 beyond insertion of posterior legs. Legs very small, ordinary, tarsus about 

 two-thirds length of tibia. The four digittdes about of equal size ; digitules of 

 claw have rather the larger knobs, which are somewhat obliquely truncate, 

 but all the digitules are fairly slender and have smalhsh knobs. Those of 

 claw reach considerably beyond tip of claw, but those of tarsus do not reach 

 any further than those of claw. 



In the covered runs of some ant, along both sides of the midrib of 

 underside of leaves of Balata, with a few young Icerya rosce. — Hort. Trm., 

 25th July, 1895. (Hart). 



This little species looks just like immature L. hes2}eridum, except that 

 it is rather more pyriform instead of oval. The females were mature and 

 contained many embryos. L. minirnum, Newst., is a very similar species, 

 but according to Newstead's brief description, differs from nanum in the 

 dermis, the antennae; and, judging from the figure of mijiimum, in the 

 digitules. I am sorry I have no minimum to compare, but it seems reason- 

 ably certain that it and nanum are distinct. Another similar species is L. 

 rubellum, CklL, but nanum has not the large claw-digitules of that msect. 



20. Lecanium hesperitlum. — On leaves of an orchid (Hart). New to 

 Trinidad. It may be known from Pulvinaria brassice, on the same leaves, 

 even when the latter has not yet formed its ovisac, by the much smaller 

 marginal spines and the seven-jointed antennae. 



22. Lecanium dejoressum. — Plenty on Hibiscus (Hart). 



23. Lecanium olece. — On Eriodendron. (Hart). 



24. Lecanium hemisphcericum. — On Aristolochia. (Hart). 



25. Vinsonia stellifera.— On Clusia (Lvmt). On Asplenium (Hart). 

 Stanhopea (Hart),
