 distributed species. It is often found in houses.

larger granules on the cephalothorax. This species

Genus CHELANOPS (Chel'a-nops) 



The genus Cbelanops is by far the largest of our genera, in- 

 cluding nineteen of our described species. No complete table 

 i)t" them has been published as yet; the following, based on one b\ 

 Banks ('95 b.) will enable the student to determine most of the 

 species: 



A. 1 lairs on the palpi very long and simple, abdomen long and 



of equal width throughout. This group is represented in 



our fauna by the two following species. 



B. Of moderate size; less than one eighth inch in length. A 



species well distributed throughout the Eastern and 



Southern States. Cbelanops oblongus 



BB. A much larger species found in Colorado and southern 



Arizona. .Cbelanops grossus 



AA. Hairs on the palpi short and thick often clavate, abdomen 



much the widest in the middle. 



B. Hand with a large tooth-like projection on the inner side. 



Cbelanops deniatus 

 BB. Hand without any projection. 



C. Fingers as long or nearly as long as the hand. 

 D. Hairs not distinctly clavate. 

 E. Inner margin of the hand not greatly swollen at 

 base.
