1917] Synopsis of Beetle Mites 127 



or almost, in outline and bearing enormous setcC. Lamellai present, 

 blade-like. Translamella a chitinous ridge. A pair of lateral lamellae 

 present. Claws tridactyle. 



Type species: N. multipilosus (Ewing). (See Fig. 1). 



This genus is erected for a peculiar species described by the 

 writer some years ago from specimens obtained in northern 

 Illinois, not far from Chicago. At the time of collection I 

 recognized that the species was quite different from other 

 beetle mites, but hesitated in making it the type of a new 

 genus. I regard this species, in a way, as a connecting link 

 between the peculiar genus Oripoda Banks and Pergande and 

 the other members of the subfamily Oribatince. It has the 

 pteromorphae of Oripoda, but the body of a true Oribata.

Genus Tegoribates^" n. gen. 



With the characters of the subfamily Oribatinae. Pteromorphae 

 attached to abdomen only, truncate in front, not extending far beyond 

 the anterior margin of abdomen, and not united by a transverse lamella. 

 Cephalothorax completely covered by a roof-like projection which 

 arises from the line of junction between the cephalothorax and abdomen 

 and extends forward almost to the tip of the former. 



Type species: T. subniger n. sp." (See Fig. 2). 



The large roof -like or hood-like projection above the cepha- 

 lothorax in this genus makes it unique among the beetle-mites, 

 and for that matter unique among all the mites in this respect. 

 The nearest approach to this condition is found in the genus 



^^Meaning a covered Oribates. 



"The descriptions of this species has been sent away for publication in Part II 

 of my series on "New Acarina."
