Figure 327 



Diagnosis: These mites are generally grayish- 

 or yellowish-brown in color. The dorsum of the 

 body is slightly convex. There are no true pseu- 

 dostigmata or pseudostigmatic organs but there 

 is a simple bristle instead.

Figure 328 



Diagnosis: The genital and anal openings are contiguous. Small, scle- 

 rotic strips or plates lie close to the genital and 

 anal openings; the anal opening is closed by a 

 pair of striplike, sclerotic plates. The pseudo- 

 stigmatic organs are either funnel- or shell- 

 shaped. Usually with raised margins^ the dorsum 

 of the hysterosoma is flat. Many of the species 

 of Camisia have characteristic elongated proc- 

 esses on the posterior margin of the body.
