A. C. OUDEMANS. ACARI. 143 



1SS4. Nalepa scrupulously describes the internai anatomy of T. longior ; his labour 

 will be in future the base of the anatomy of Tyroglyphidae. 



1887. GROULT too briefly describes the species (longior) in three lines. 

 18S8. CANESTRINI briefly diagnoses the species (longior). 



1888. CANESTRINI amply describes longior and gives very good drawings of it. On 

 the dorsum a pair of short hairs a little before the middle is omitted. The tarsi are drawn 

 very long, except in legs I ail the tarsi are as long as fémur, genu and tibia together ! The 

 suckers on the tarsus IV of the maie are placed „presso la base", I think he lias meant, 

 like BERLESE, 1884, in the proximal fourth part of the tarsus. 



1890. MONIEZ mentions a case of toughness of life of T. longior which lived several 

 days submerged in sea-water (v. 2, p. 27), and its occurrence in France (v. 3, p. 32). 



1892. MÉGNIN only diagnoses the species (longior) in two lines. 



1893. KARPELLES mentions the occurrence of longior in Hungary. 



1894. Moniez's article was not within my reach. 



1S95. TROUESSART only mentions the présence of longior in our houses in the same 

 localities as siro. 



1897. BERLESE only quotes longior in his key to the species of Tyroglyphus. 



1898. Oltdemans cites the mite, under the false name of horridus, among the Acaridiae 

 of the Netherlands. 



1899. BERLESE mentions the rare and accidentai présence of longior on plants. The 

 accompanying figure is a reduced reproduction of his Tyroglyphus infestans (1884), now under 

 the name of T. longior. 



1899. KRAMER diagnoses briefly the species. On p. 139 he tells us that the suckers 

 on the tarsus IV of the maie are situated in the proximal fourth part of the tarsus, follow- 

 ing in this description BERLESE, 1884, and CANESTRINI, [888. On p. 140, however, the 

 suckers are placed in the proximal tliird part of the tarsus. In reality the position of thèse 

 suckers differs considerably in différent races. The inner pair of the cephalothoracal hairs is 

 said to be placed before the outer pair, which in reality is never the case! 



1901. MlCHAEL in his Standard-work of British Tyroglyphidae v. 1. discusses the 

 external anatomy of the members of this family and repeatedly quotes the species, called 

 by him longior. 



1903. In the second volume he amply describes the species. In the description of the 

 maie, also in the figure representing it, the two spines are placed behind the anal suckers, 

 in stead of before them. The two short sublateral dorsal hairs are omitted. The two long 

 dorsal hairs are placed far more backward than hitherto has been noticed by earlier writers. 

 Probably the english race considerably differs from the continental ones. Of the tarsal suckers 

 of the maie the one is delineated exactly on the end of the proximal thircl part of the tarse, 

 the other exactly in the middle. MlCHAEL has also found a bigger variety on cheese. The 

 hairs are described to be serrate, or better plumiform, with two opposite ranges of minute 

 hairs, or spines. 



1904. OUDEMANS mentions the accidentai occurrence of longior in urine. 

 Description of the New Guinea samples.
