APOLONIINAE 
hi 
Remarks. — The author compares the genus with Hemitrombicula Ewing, but as Wharton 
has shown, the latter is not in any way associated with the Trcmbiculids. The closest relation- 
ship of Nothotrombicula is with the various genera of the subfamily Apoloniinae, but it is near to 
Audyana n. gen. in the form of the scute, yet differs in the leg-segmentation, the form of the 
AL scutal setae, and the absence of any AM. 
Genus Grossia nov. 
Belonging to the subfamily Apoloniinae sensu lato of the Leeuwenhoekiidae, and 
distinguishable by the absence of AM scutal setae, by the tarsi of all legs being furnished with 
a single claw, and by a pair of shorter apically spathulate tenent setae. 
Type Grossia onychia n. sp. 
Remarks. — As given in the generic diagnosis this remarkable genus appears to belong to 
the subfamily Apoloniinae of the Leeuwenhoekiidae in that all the legs are 7-segmented. It 
comes closest to the genus Neotrombidium but differs from this and all other genera of the family 
in the absence of the AM scutal setae and the presence of paired spathulate setae on each tarsus 
at the base of the single claw, a feature common to the Tetranychidae, but hitherto unknown 
in the Trombiculidae or Leeuwenhoekiidae. 
The genus is dedicated to the finder. 
A, dorsal and ventral halves of larva; B, scutum ( x 450); C, chelicer; D, palp; E, tip of tarsus.
