On p. 247 Michael describes the mandibles of his spinipes 

 (michaeli mihi) and observes: »Berlese tuakes the dentition more 

 elaborate than I do. I have not, however, been able to see the 

 mandible quite as he draws it in any specimen which I have 

 dissected." Well, I will readily believe him, for, as I already 

 pointed out, his and Berlese's species are different ones. Moreover 

 Berlese's drawing is more artificial than accurate. Such long 

 hairs on the anterior half on the body? No pair of short hairs 

 on the hinder half of the dorsum ? 



Patria. Consequently Gl. michaeli hitherto is only recorded in 

 England. It is an insular form.

1903 Glycyphagus burchanensis Oudms. in Entom. Bericht, p. 103. 

 Froni the Isle of Borkum 1 found among my preparations a 

 few days ago another species (or variety? the specimen is dam- 

 aged) which I will call burchanensis and describe in the Tijdschrift 

 voor Entomologie. It is closely related to michaeli, has also a 

 scale on the ventral side of femur 3 instead of a hairy hair; but 

 the scale is short, lanceolate and provided with long marginal hairs. 



22. Glycyphagus privatus Oudms. 



(With Plate X, fig. 37-45). 



1903 Glycyphagus privatus Oudms. in Entom. Bericht, p. 103. 



This species is closely allied to Gl. domesticus (de Geer) and 

 Glyc. ornatus Kramer. 



Larva unknown to me, but certainly provided with a rudimental 

 dorsal shield, like that of Gl. domesticus (de Geer). 



Nynipha I and II unknown to me, but certainly provided with 

 the rudimental dorsal shield, like those of Gl. domesticus (de Geer). 

 Male (Fig. 37—43). Length 336—416 f*. — Colour pale straw 

 coloured. — Shape. Before the shoulders triangular, and constricted 

 behind the implantation of legs III. My three males have this shape 

 (See fig. 37) but I may fix here again the reader's attention on
