142 A. C. OUDEMANS. ACARI. 



in the maie the two dorsal suckers on tarsus IV, but he does not says where they exactly 

 are placed on the tarsus. He lias bred the species, feeding it with pièces of Cantharis offici- 

 nalis; he has observed the coitus; and he has made expériences about their toughness of 

 live, keeping them in the cells more than one month without any food. But he does not 

 give any detailed description. The drawing of LACKERBAUER represents a female with ventral 

 aspect, containing 3 eggs. The hairs between the rostrum and legs I, a hair between legs I 

 and II, a hair on genu I and the 4 cephalothoracal hairs of which the distal portion is visible 

 and two dorsal hairs behind legs IV are drawn haired; the other hairs smooth, which is a 

 mistake. Moreover the drawing is the best hitherto published ; it occupies a space of 25 

 centimeters length and 16 width. 



1867. FUMOUZE and ROBIN verbally transcribe what LABOULBÈNE et ROBIN hâve 

 published, 1862, and what FUMOUZE has written, 1867. Also LACKERBAUER'S drawing is 

 republished. 



1868. FUMOUZE and ROBIN only quote the name of GERVAIS Jongior." 



1868. ClaparÈDE tells us that the development (embryology) in longior is the same 

 as in siro. 



1877. MURRAY only relates the investigations of LABOULBÈNE, FUMOUZE and ROBIN. 

 Further he identifies — like the french authors — Turpin's Acarus horridus and Weekes' 

 Acarus with the species in question. With MlCHAEL, 1903, I consider thèse Acari, however, 

 identical to Glycyphagus domestiais which often occurs in the dust of Laboratories. 



1879. OUDEMANS mention the occurrance of the mite in the Netherlands. 



1880. Haller in both his articles cited, mentions his finding of Acarus dimidiatus 

 KOCH in Switserland and in Wurtemberg „massenhaft unter feucht gehaltenen Blumentôpfen." 



1S80. HALLER dwells upon the internai anatomy of his Tyroglyphus setiferus, certainly 

 the same species as T. dimidiatus (Herm.). Successively he describes the nervous System, the 

 external organs of palping, the olfactoric hairs, the intestinal tract, the nephridia, the génital 

 apparatus both of maie and female, the external anal suckers of the maie, the post-anal 

 copulation-hole of the female, the embryology. 



1880. MÉGNIN describes the species too shortly, in but four lines. 



1882. WlLSON's article is unknown to me. 



1S83. BerlÈSE enumerates T. setiferus, found in cheese, among the Acari of Sicily. 



1883. KARPELLES briefly describes T. longior; apparently he has used LABOULBÈNE's 

 description. He does not say that the mite occurs in Hungary. 



1884. BERLESE describes and delineates under the name of T. infestans a mite, which 

 generally is considered as the same as T. longior Gervais. It strucks us that the démarcation 

 of céphalothorax and abdomen is interrupted in the middle; that two longitudinal grooves 

 ornate the abdomen (compare KOCH, 1841); that a pair of short hairs a little before the 

 middle of the dorsum is not delineated ; that the insertion of a pair of the longer hairs a 

 little behind the middle of the dorsum is overlooked. For the first time we observe a drawing 

 of the two anal suckers and of the two tarsal suckers of the maie. Before each anal sucker 

 there is a pin, or very short bristle. The two tarsal suckers are placed in the proximal fourth 

 part of the tarsus IV. The species is found on cheese and other cibarious objects in Italy. 



1884. BERLESE briefly compares his infestans with siro.
