purpurata. Coll. G. Nicholson. This is a greenhouse pest in 

 this country. It also occurs, under glass, in the United Stat 

 and in the open air in Mexico, West Indies. Brazil, Australia, 

 New Zealand and elsewhere. It feuds on a variety of plants. 



Chionaspis (Hernichionaspis) aspidistrae. Sign. In all stage* 



on the stem scales of Zamia Loddigesii. Coll. R. Kett. This is a 

 fairly common species in Great Britain. It has also been recorded 

 from Australia, Brazil, Trinidad, India, Japan, in Canada (under 

 glass), and elsewhere. Its favourite food plants are various kinds 

 of ferns, but it has also been found on orange, mango, fig, 

 pepper, &c. 



Pinnaspis buxi, Bunche. Female only. On an unnamed mono- 

 cotyledon, and on Monstera deliciost. Coll. G. Nicholson. Less 

 common than the preceding species in Great Britain. Common in 

 the West Indies, and has been recorded from the United States 

 (? under glass), and elsewhere. 



Mytilaspis pomorum, Bouchr (= M. ulnn\ Linn.). Females 

 only. On Cotoneaster sp.. Gonitis cUba $ tsnd Helianthemum sp. 

 Coll. W. Dalli more. This is the well-known " Mussel Scale M of 

 the apple. It feeds, however, on a variety of plants, and has a 

 wide geographical distribution. 



LEUANIINAE. 



Lecanium (Calymnata) hesperidum, Linn, Females and male 

 puparia. On Carludovica palrnata. Coll. G. Nicholson. This 

 common species is largely parthenogenetic, the males being 

 extremely rare — in fact have been discovered on two or three 

 occasions only. The finding of the male puparia at Kew is 

 therefore of great scientific interest. It is a general feeder, and 

 almost cosmopolitan in its distribution. 



^ Lecanium {Calymnata) hesperidum, var. alienum, Douglas. 

 Females only. On Furcraea macrophylla and Aloe ciliaris 

 (House No. 5). Coll. G. Nicholson. Common and generally 

 distributed. 



Lecanium (Eu lecanium) persicae, var. sarothamni, Douglas. 

 Females only. On Cotoneaster. Coll. G. Nicholson. This may 

 be considered a phytophagous variety of the common peach scale ; 

 it is smaller than typical examples 

 differ in any other particular. 



Lecanium sp. ? Possibly L. hesperidum, but the specimens 

 were all badly parasitised with a chalcid larva, and could not be 

 definitely fixed. On Aloe ciliaris (House No. 5). Coll. W. Down. 



Lecanium (Saissetia) oleae, var. testudo, Curtis. Females only. 

 On Furcraea sp. and Aloe ciliaris (House No. 5). This variety 

 has not occurred outside the British Isles. It is much smaller 

 and browner than typical oleae. 



Dactylopius (Trechocorys) citri, Risso. Females only. On 

 Phormium tenax (Winter Gardens). Coll. W. Taylor. This is 

 the common " Meaiy Bug," and has been met with on a variety of
