MITES OF FAMILY CHEYLETIDAE — BAKER 285 



treme small ; that part of rostrum overlying the palpal trochanter has 

 two sharp teeth as figured. Anterior shield relatively large, covering 

 most of propodosoma ; four pairs of lanceolate serrate marginal setae ; 

 two pairs of dorsosubmedian lanceolate serrate setae. Hysterosomal 

 shield narrowing posteriorly; with four or five pairs of lanceolate ser- 

 rate marginal setae. Tarsus I, 113/^ long; tibia I, OOju, long; tarsus I 

 with a large lanceolate sensory organ and a small simple guard seta ; 

 tibia I with a short rodlike sensory seta. Leg I, 428/a long; leg IV, 

 328/i long. Length of body 400/a, including rostrum 571ju,; width 

 285ju. 



Type habitat. — On bird skin, Psittinus cyanurus {=P. incertus), 

 probably preying on feather mites. 



Type locality. — Malacca, Straits Settlements. 



Oudemans (1906) gave tlie above information on habitat and distri- 

 bution. The following interception records are available (if taken 

 on plant material the host is not listed) : Azores, at New York, N. Y. ; 

 Belgium, at Charleston, S. C. ; Holland, at Philadelphia, Pa.; Italy, 

 at New York, N. Y. ; Portugal, at New Orleans, La. ; China, at Hawaii ; 

 Japan, at Seattle, Wash. ; Java, at Hawaii ; Philippine Island, at San 

 Francisco, Calif.; Straits Settlements, at Norfolk, Va. ; Malaya, at 

 Hawaii ; west coast of Africa, at Philadelphia, Pa. ; Barbados, at New 

 York, N, Y. ; British Guinea, at New York, N. Y. ; Colombia, at New 

 York, N. Y. ; Cuba, at Norfolk, Va. ; Mexico, at Brownsville, Tex. 

 Material is also on hand from Cuzco, Peru ; Barranquilla, Colombia, 

 on Araeocerus fasciatus eggs ; St. Croix, Virgin Islands, on domestic 

 fowl; Richmond, Va., on Ephestia elutiella; Shreveport, La.; Red- 

 wing, Minn,, on wheat screenings; Dallas, Tex,; Atlanta, Ga., in 

 "powder" ; Farrington, 111. 



Cheyletus malaccensis resembles closely G. rapax Oudemans, and 

 the differences between them may prove to be a variation within a 

 single species. The fact that there appear to be five pairs of setae on 

 the hysterosomal shield strengthens this belief.
