Centipedes are usually carnivorous. Perhaps Millipedes may be 
intended but we do not know of these as doing any damage in India. 
The next group of sugarcane pests includes those found sucking 
the juices of the plant :— 
Pyrilla aberrans. 
> pusana. 
»  perpusilla. 
Callitettix versicolor. 
Phenice mesta. - 
Aphids. 
Aleurolobus barodensis. 
Neomaskellia bergi. 
Ripersia sacchari. 
Pseudococcus (Dactylopius) sacchari. 
Ks - saccharifolit. 
Aclerda japonica. 
The three species of Pyrilla are all very similar in general appearance 
and habits. In South India we get Pyrilla perpusilla [‘‘ South Indian 
Insects,” pp. 493-494, fig. 381] but at Pusa we get mostly P. aberrans 
together with small nembers of P. pusana and perpusil'a. I had a note 
on these Cane-hoppers recently [Note 97, Bulletin 59] and a lengthy 
Memoir by Mr. Misra is in the press and will be ready shortly and, as 
this contaims all the information available, we need not go into this 
agai now. 
Callitettix versicolor is a small brightly coloured Cercopid bug often 
found on cane in some numbers. I found it in numbers at Tatkon in 
Burma in September 1914. We do not know anything about any 
damage done by it and it is probably not a pest. 
Phenice masta also is often found in numbers-on cane. It is des- 
eribed and figured in ‘South Indian Insects,” p. 493, fig. 380, and is 
often found on cane-leaves in little colonies. It never does any damage 
so far as we know and the immature stages do not seem to occur on cane- 
leaves ; possibly they live on the dead leaves and trash at the bases of 
the stems. 
Aphids sometimes occu? on cane but we seem to know nothing about 
them and therefore they are probably not of much importance as pests. 
The Aleyrodi'z £ und on sugarcane in India include Neomaskellia 
berg: and Alewrolobus barodensis. The former is described and figured 
in “ South Indian Insects,’ p. 507, fig. 394, and the latter in ‘ Indian 
Insect Li’e,” p. 749, figs. 524-525; but doubtless other speci s occur 
also. This is a group which badly wants working up in India and I 
gave last year a short summary of the present state of our knowledge 
.
