Leguminosse, growing in the gardens. Mr. E. Ernest Green, Govern- 

 ment Entomologist, Ceylon, identified them as Chionaspis (Hemi- 

 chionaspis) minor of Maskell. Mr. Green noted that " Professor 

 R. A, Cooley, of the Mrontana College of Agriculture, United States 

 of Amercia, who has recently been making a special study of the 

 genus Chionaspis, considers that my C. albizziae is a synonym of C. 

 minor ; and I think that he is probably correct, though there are one 

 or two small distinctions. In Ceylon, C. albizziae, affects injuriously 

 many leguminous trees and plants." 



The following description of the insect is an extract from " the 

 coccid genera Chionaspis, and Hemichionaspis" from the Special 

 Bulletin, Hatch Experiment Station of the Massachusetts Agricul- 

 tural College by Professor R. A. Cooley, B.Sc, dated August ioth 

 1899:—

" Egg. — ' Orange, numerous' {Cockerell)." 



Scale of Femal e.— Length r8 to 2-3 mm. Elongated, broadened posteriorly. 

 Moderately thick in texture, white. Exuvia 7 mm. long, yellowish brown. 



" Female. — Median lobes distinctly darker than the rest of the pygidium ; 

 outer edge of each divided into from two to four crenationp. Second pair rudi- 

 mentary or wanting ; occasionally fairly well developed. Third pair wanting. 

 The gland-spines are arranged as follows : — 1, 1, 1, 1, 2 — 3. The marginal orifice 

 nearest the median lobes is situated on a broad conspicuous prominence. Dorsal 

 gland orifices few in number. Second row wholly absent. Third and fourth rows 

 with posterior groups numbering 1 — 3, their anterior groups being either absent or 

 replaced by small and obscure almost circular orifices. Median group of circum- 

 genital gland orifices 6— 11 ; anterior laterals 12—20 ; posterior laterals 10 — 18." 



" Scale of Male. — Length 9 mm. Very distinctly tricarinate. Exuvia. 

 yellowish-brown." 



"Remarks.— This insect was first found in New Zealand, from which country 

 Maskell originally described it. Cockerell has frequently recorded it from the 

 West Indies, and I have also published its occurrence in Panama and Florida. 

 The species is very common in the West Indies, and it is probable that these 

 islands are its original home." 



"Maskell has taken the insect on Parsonsia, ^Rhipogonum scandens ; 

 Cockerell on Hibiscus, Capsicum, Pelargonium, ' Cotton,' * Pepper, ' and ' Cocoa- 

 nut-palm '; and I have recorded it on Melia azedarach also." 



Of its destructiveness Cockerell says: "From its frequent abun- 

 dance it becomes quite troublesome on garden plants." I have been 

 informed by Professor Quaintance that the species severely attacks
