lie. In appearance P. articulaius is very like the red scale of Cali- 

 fornia (Chrysomphalus aurantii) but here it does even more damage, 

 in proportion to the number of citrus trees grown, than does the 

 red scale in the citrus growing districts of the United States. But in 

 considering this statement one must bear in mind that fumigation is 

 never practiced in Peru and that parasites, even though exceptionally 

 numerous, do not seem even to be a serious check on the multiplication 

 of this insect, not to mention controlling it. 



The following is a Mst of hosts and the localities where collected, to date, but addi" 

 tions are constantly being made as this inquiry into the coccid fauna of Peru pro- 

 gresses. Collected on: orange, Hacienda MaUares (Department of Piura) ; orange, 

 Pueblo Tamarindo (near Paita); orange Chapaird (near Piura); orange, Hacienda 

 MaUares (Department of Piura) ; orange, Coscomba (near Piura) ; lemon, Hacienda 

 San Jacinto (near Paita); lime, Hacienda San Jacinto (near Paita); orange, San 

 Bartolome (Department of Lima); orange, Munuela (Department of Piura); orange,

 the interior of Peru); Anona cherimoUa, Chosica; Ficus nitida, Lima; Ficus nitida,

 enda San Jacinto (near Paita); Anacardium occidentalis, IN'omala (in the Andean 

 foothills. Department of Piura; Jasminum arabica, Lima; Jasminum azoricum, 

 Nerium oleander, Lima; Ligustrum japonicum, Lima; Plumieria sp., Piura; Cocos

 Lima; Bignonia stans, Piura; Magnolia grandiflora, Lima; Eriobotrya japonica,

Pseudococcus citri Risso. 



The above insect, in temperate climates, is generally considered 

 as a greenhouse pest but in the warm, equable climate of Peru it is to 

 be found out-of-doors in all localities where its food plants grow. It 

 is very subject to both parasitic and predaceous enemies, however, 

 and has not as yet been noted in any abundance in any one locality, 

 although a slight search will reveal it almost anywhere in limited 

 numbers. It is not a serious menace to any cultivated crop and, 

 owing to this fact and its general distribution and comparatively 

 slight numbers, only a few notes relating to it have been accumulated. 



Collected on: Coffea arabica, Lima; Gossypium peruvianum, Hacienda San Jacinto 

 (near Paita), and throughout the Depaitment of Piura at different dates; Asparagus 

 officinalis, Sol Sol (Department of Piura), (Rust) and Hacienda MaUares (near Paita); 

 cotton, Lima. 



Pulvinaria sp. nov. (?) 



In the Department of Piura a species of Pulvinaria has repeatedly 

 been collected but always in the immature stages so that it could not 

 be classified. It is of medium size and green in color, and the begin- 

 ning of an ova-sac, in a few cases, distinguished it from all coccus-like 

 forms. Never seen in damaging numbers. 



CoUected on: Gossypium peruvianum, Hacienda Samdn (near Paita), and at Paccha
