the new species of mite here described was isolated from the clothes of a small boy, using the method detailed in the above paper .Various tarsonemoid mites have been implicated in rashes, the most infamous of these being species of the genus Pyemotes ( = Pediculoides ), parasites of insect larvae and pupae, and capable of penetrating the human skin: a world review of the dermatological significance of these mites is nearing completion (HEWITT et al., in preparation). Other species described in the literature as initiating rashes are Microdispodides karafiati (Krozal), causing eczema on both hands of a lumberman (BORH, 1956), Tarsonemoides noxius Humiczewska, embedded in the skin of a boy's fingers and in the trunk and arm of a man, causing a rash similar to scabies (HUMICZEWSKA ,1967), and an undetermined species of Tarsonemus found in small vesicles in a woman's cheek, accompanied by scabies-like grooves (BOYE and HIVIEREZ, 1934). This suggests that the occurrence of tarsonemoid mites in proximity to the skin should not be ignored as a possible cause of the more obscure types of rash; however although we personally have found them in a few other instances in the clothes of patients with unexplained rashes, one cannot satisfactorily establish their pathogenic role unless they can be found in actual lesions. Moreover, it is possible that contact alone may cause an allergic reaction in some people . Circumstantial evidence is also evasive, as their minute size makes them particularly difficult to isolate, in contrast to the larger species of Acari. Associated with Daidalotarsonemus in this child patient was Ty- rophagus sp ., whilst other patients had Tyrophagus sp . , Glycy- phagus destructor (Schrank) and Dermatophagoides pteronyssinus (Trouessart ), all of which have themselves previously been incriminated in skin rashes (see HEWITT et al. for a few key references). Villagers in Sheviock believed that their rashes were in some way connected with winds blowing dust from the nearly silo, and indeed a single sample of corn dust contained Ty rophagus sp . and G . destructor as well as Acarus siro (L . ) (cause of 'bakers' itch"), Kleemania plumosus (Oudemans) and an undetermined tarsonemid. 194
