34. Glycyphagus ornatus Kram. 



Kramer (Zeitschr. d. ges. Naturw., vol. 54, p. 437) says of this 

 species: »Das Tarsalglied des vierten Fusspaares tragt unten in 

 der Mitte des innern Seitenrandes zwei kurze behaarte Borsten." 

 I fail to observe these hairs. Kramer does not say whether the 

 tarsi are hairy or not. They are richly hairy, as in Glycyphagus 

 spinipes (C. L. Koch). 



Berlese (Ac. Myr. Scorp. Ital. 29, 3) describes the tibia of the 

 first and second pair as bearing a pectiniform apophysis, but he 

 does not inention that this peculiarity occurs only in the male. 

 The tarsus he describes as: »setis destitutus, nudus." He seems to 

 have drawn a hermaphrodite, for the pectinated hairs on the tibiae 

 1 and 2 are male, and the copulation-tube is afemale characteristic. 



My specimen has the characteristic bifurcated and feathered hair 

 and the oblong pseudostigma between the coxae 1 and 2. 



The skin is finely granulated. 



Nywph. Here I observe no hairs on the tarsi, and only one 

 feathered hair in the middle of the underside of the tarsus 4. 



Query. Have Kramer and Berlese described the tarsi of the 

 nymph, instead of those of the adult? 



35. Labidophorus Kram. 



As the genera of Tyroglyphinae have each their special and cha- 

 racteristic form of hypopus, we are obliged to adopt the genus 

 Labidophorus of Kramer, because its hypopus has two claspers on 

 the ventral side of the posterior abdomen whilst it has no suckers. 

 The only species hitherto described is Labidophorus talpae Kram. 

 (Glycyphagus krameri Michael).
