1504 PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



Tachardia lacca, Kerr. 



Locality. — Saidapet, Madras. 



Habits. — Only on one occasion was this noted and that not in large 

 ■numbers. 



GUAVA. 



This plant, although subject to the attacks of only a few Coccids, 

 often suffers considerably from one or two species. 



Pulvinaria psidii, Msk. 



Locality. — This is found all over the country. 



Habits — It is very often found doing considei able damage to guava 

 trees. The leaves of badly-infested trees present a dark blighted 

 appearance. 



Lecanium hemisphcericum, Targ. 



Locality. — Coimbatore District. 



Habits. — Though this is a specific bad pest of coft'ee, I have noted 

 it causing appreciable damage to guava. 



Mytilaspis pallida, Green. 



Locality. — God^vari District. 



Habits. — Very rare. Noted only once and that as a minor insect. 



Orange, Lemon, Pomelo, etc. 



So far as known there are not as many Scale-insects affecting the 

 ■Citrus trees in Southern India as one may be expected to find, judging 

 from the conditions in other Citrus-growing countries. I have not 

 yet come across the well-known " Orange Scale " {Aspidiotus aurantii, 

 Msk.) on Citrus trees, although the species is not absent in South India. 



Aspidiotus ficus, Ash. 

 Locality. — Malabar and Nilgiris. 

 Habits. — Occasionally bad. 



Parlatoria ziziphus, Lucas. 



Locality — Coimbatore. 



Habits. — Rarely found. Another species of Parlatoria is also found 

 on Citrus in the Mysore uplands.
