small, aboiit 9 fi long, oval, about 63 // from bases of median lobes; 

 lobes four, crenulate, shaped as in C. minioscE, but the median lobes are 

 broader, angular instead of sloping on the outer side ; margin beyond 

 the lobes denticulate and finely crenulate ; club-shaped thickenings at 

 inner bases of median lobes, about twice length of lobes ; a pair of 

 thickenings between first and second lobes, as in mimosie : three 

 thickenings between second and third lobes, the middle one longest ; 

 two at interval between third and fourth lobes, the middle one being 

 absent ; one or two beyond the fourth. 



Hah. On bark of branches of Mimosa, Verulam, Natal 

 {Fuller, No. 9). With Lophococcus mirahilis. This, in its scale 

 and other characters, is so very like the Mexican C. mimosce, 

 Comstock, that I was not perfectly sure it was distinct. I sent 

 some to the Department of Agriculture at Washington, and 

 Mr. Kotinsky kindly compared them with Comstock's types of 

 mimosce ; he found the differences to be constant, and the species 

 clearly distinct. 



Pseudaouidia davigera, n. sp. 



5 . Scale, 2^ mm. diam., moderately convex, blackish, entirely 

 covered by the epidermis of the twig, except the small shining sub- 

 lateral orange-ferruginous exuvias. 



? . No circumgeuital glands, even when full of embryos. Similar 

 to P. tesserata, but the median lobes are scarcely notched on the inner 

 side ; the second and third lobes are narrower (width of second lobe 8 /* 

 in clavi(jera, 18 in tesserata) ; margin beyond fourth lobe serrate as if 

 with many small lobes ; two large round spaces below the incisions 

 laterad of the median lobes, which, properly focussed, give the appear- 

 ance (with the incisions) of the club-shaped processes of Hoirardia 

 hidavis : anal orifice further from hind end, being 111 to 129 /x distant 

 from the tips of the median lobes (in tesserata 84 ^). 



Hah. Durban, Natal, on twigs of camellia in the Botanic 

 Gardens (Fuller, No. 1). The appearance of the scales, covered 

 by the bark, and the club-shaped processes, strongly suggest the 

 genus Howardia. There is also some evident affinity with 

 Aspidiotus moorei. Green. The genus Pseudaonidia seems to be 

 sufficiently distinct, mcluding the following forms described 

 under Aspiodotus : — P. thece (Maskell) ; P. thece rhododendri 

 (Green) ; P. duplex (Ckll.) ; P. pceonice (Ckll. as var. of duplex) ; 

 P. trilohitiformis (Green) ; P, tesserata (De Charmoy). 



Hemichionaspis cyanogena, n. sp. 



? . Scale about or hardly 2 millim. long, slightly convex, white ; 

 narrow, with much the outline of H. them ; exuviae orange, varying to 

 pale yellowish. 



(? . Scale of the usual form, not carinate. 



?. Differs from H. minor sls follows: — Lateral margins of seg- 

 ments not produced ; median lobes not so produced, shaped more as 

 in H. Hiussiembr, the two lobes together 27 n* broad and 12 /* long: 

 spine-like squames more numerous, the formula (following the method
