910 EXPERIMENT STATION RECORD. 



appears iu the form of a diplococcus. It differs, hoveev^er, iu being very 

 much smaller — 0.5 to 0.0 /( as compared with 1 u — and iu the young 

 colonies having a finer granulation. 



In experiments with live worms fed with a mixture of Streptococcus 

 pastorianns and Micrococcus lardarius, the symptoms of both flacherie 

 and grasserie Avere produced. This result is compared with the fact 

 that iu the grayish diseased animals ofteu met with Streptococcus 

 2)astorianus and Jlicrococcus lardarius are always found. 



A simple experiment is recorded showing how the virulence of 

 pebrine may be increased and how flacherie and grasserie might be 

 disseminated among insects. Diseased moths Avere ground up in a 

 mortar with a little water. Into this mixture pieces of bread were 

 dipped and then fed to the common sparrow {FringiUa domestica). 

 Later the excrement of the bird was smeared on leaves upon which 

 silkworms were feeding. The latter soon developed the characteristic 

 symptoms of i)ebrine. If the excrement became dry no such result 

 followed, but the other diseases, flacherie and grasserie, appeared, never- 

 theless.

 This paper discusses the species of Thrips living on willow leaves, Thrips salicaris, 

 and itsrelatioushiiis, and an organ found on the leg of Phlojotbrips which recalls the 

 auditory organ of Locusta. The organ occurs on all three pairs of femora.
