One parcel of palm leaves yielded hosts of the curious 

 coccid, Ischnaspis jiliformis (Plate I., fig. 4), which 

 also was observed on mango leaves. This was discovered 

 for the first time some years ago by Mr. DOUGLAS 

 upon several plants in the Gardens of the Royal 

 Botanic Society, Regent's Park ; and named by him 

 as above, but these leaves from British Guiana gave us 

 the information whence these hot-house pests had 

 originally come. 



On mango leaves and certain orchids was found the 

 very beautiful coccid, Vinsonia stellifera (Plate I., fig. 2). 

 This had only been seen previously by the entomolo- 

 gists, SlGNORET and WESTWOOD. The former had his 

 specimens from Reunion, and the latter found his in 

 plant stoves in Paris. The insect was regarded by both 

 as the most remarkable member of the whole family. 

 SlGNORET speaks of it as <f cette magnifique espece." 

 In its immature condition it is like a little waxen star, 

 but in the adult state it is like a tiny tent pegged down 

 to the leaf at seven points. The mango leaves were 

 tenanted by a variety of curious coccids. One, at least, 

 proves to be new. It has recently been named by Mr. 

 Ernest Green, of Ceylon, where it is very prevalent, 

 as Lecanium mangiferae (Plate II., fig. 1). And another, 

 after considerable difficulty, was identified as Aspidiotus 

 personatus (Plate II., fig. 2) of Cornstock. This latter 

 has more recently been found on the leaves of other 

 plants besides the mango. I am told that several 

 new species of Aspidiotus have been discovered by 

 Mr. MORGAN, who will describe and name them 

 in due course. 



Cupania sapida yielded a variety of Coccidai. Some
