Mexico A. '.7. Morrill (September ?): A species of tingitid appeared on 
cotton in the Yaqui Volley in early summer and has ~oec~a under ob- 
servation. Although 10 per cent of the leaves were destroyed in 
some small are-as of a few acres each, the insects did not multiply 
to keep up with the growth of the plants. By the end of the first 
week in September there was no change in status. The insect has

SSLLOT' SUGAECAJJE APHID ( Sipha flava Forbes) 
Porto Rico A. Hi Rosenfeld (August 29): ' The attacks of this louse in Porto 
Pico are always limited to periods of drought and generally to 
tho Uba, or Chinese type of sugarcane, although they at times 
ottack the true Saccharur. officii rum varieties on the normal ly 
dry and irrigated couth coast. In the latter case, however, 
they are never as numerous as on the Chinese canes, which they 
may at times entirely kill out in periods of prolonged dro\ight. 
As it has just rained in the Arceibo district, this outbreak vail 
prhbably be of slight importance.
