ADULT 



Body. — Usually oval, wider behind; sometimes almost elliptical. Margins 

 composed of irregular quadrangular plates or cells which often have one or 

 more circular pits. In some specimens a very small, short, fine hair is visible 

 arising frcm some of the pits. Like reflexus this species varies greatly in 

 size. Nuttall et al. give size ranging from 4.0 x 2.5 to 12.7 long. Specimens 

 in the collections of the Rocky Mountain Laboratory show sizes within the 

 range published. 



Integument. — Surface of dorsum and venter with numerous rounded or 

 sinuous, shining wrinkles. In some specimens the sinuous elevations are unusu- 

 ally long. 



Discs. — Numerous, large, variable in size, oval or circular, and radially 

 arranged. Other discs not radially arranged are found in the submarginal areas. 



Buttons. — Usually numerous but faint and sparse in some specimens. 



Legs. — Moderate in length and size. Some specimens from Southern 

 United States have the legs short and small. Surface irregular with hairs short 

 and fine. Subapical dorsal protuberances mild or absent on tarsi I to III; 

 absent on tarsus IV. Length of tarsus I, 0.57 to 0.75; metatarsus, 0.51 to 0.81. 

 Length of tarsus IV, 0.72 to 0.81; metatarsus, 0.66 to 0.78. 



Coxae. — Coxae I and II well separated; all others contiguous; surfaces 

 longitudinally wrinkled. 



Folds. — Coxal and supracoxal folds present. 



Capitulum. — Removed from the anterior margin of the body by about the
