MITES OF FAMILY CHEYLETIDAE — BAKER 299 



tibia I, llO/x long; tarsus I with minute claws and a long rodlike 

 sensory organ more than one-half as long as tarsus ; tibia I with long 

 clavate sensory seta and one large and two small lanceolate serrate 

 setae. Claws on legs II, III, and IV normal as in female. Length 

 of body 266;Li, including rostrum 380/^; width 166^. 



Type habitat. — Associated with grapevine scale. 



Tyf& locality. — Kirkwood, Mo. 



The mite was first named and figured by Banks in 1904 and described 

 in 1906. In his 1906 description Banks stated that the mites were 

 collected from grapevine scale {Asjndiotus uvae) by Professor Web- 

 ster at Lafayette, Ind., in December. However, in checking over the 

 original notes made by Pergande it was found that the mites were sent 

 in by Miss Murtfeldt from Kirkwood, Mo., in December 1888, from 

 grapevine scale. These mites were of both sexes. Other specimens 

 examined were Swing's type, male, which was taken under log, Ur- 

 bana. 111., July 1, 1908, by H. E. Ewing; male and female specimens 

 on slide without data; males from gall on sycamore branches, Jack- 

 sonville, 111., March 1926 ; a female collected in rice straw from India 

 by Lennox and Rosanoff at New York, December 15, 1944 ; and a male 

 and a nymph collected in 1947 at Mount Holyoke College, South 

 Hadley, Mass., by Alice Deardorff.
