I find in the collection a single specimen of this genus. As it is a fe- 

 male, I am unable to refer it to a species, as the specific characters are 

 very largely based on the form of the male copulatory appendages. 



Habitat: Douglas Co. (G. D. Hanna). 



Family LYSIOPETALID^. 



9. Lysiopetalum lactarium (Say). 



Jitliis lactarium Say. Jour. Phila. Acad., vol. II, p. 104 (1821). 

 Lysiopetalnm lacta7'ui))t Packard. Amer. Natur., vol. XVII, 

 p. 555 (188.3). 

 One specimen collected was found feeding on the crushed abdomen of 

 a freshly killed cricket. 



Habitat: Anderson Co. (E. H. Taylor) ; Bourbon, Chase and Cherokee 

 Cos. (Biol. Survey) ; Cowley and Douglas Cos. (writer) ; Elk, Graham 

 and Greenwood Cos. (Biol. Survey); Jefferson Co. (writer); Marion, 

 Osage, Pottawatomie and Riley Cos. (Biol. Survey) ; Sumner Co. (W. O. 

 Riley); Trego Co. (Biol. Survey). 



Order ANOCHETA. 



Family SPIROBOLID^. 



10. Arctobolus marginatus (Say). 



Jidus viarginatus Say. Jour. Phila. Acad., vol. II, p. 105 (1821). 

 Arctobolus marginatus Cook. Harr. Alaska Exped., vol. VIII, 

 p. 65 (1904). 

 Habitat: Anderson Co. (E. H. Taylor) ; Bourbon Co. (Biol. Survey) ; 

 Butler Co. (E. C. Harrah) ; Cherokee and Coffey Cos. (Biol. Survey); 

 Cowley Co. (writer) ; Douglas Co. (G. D. Hanna and writer) ; Jeffer- 

 son Co. (writer) ; Labette and Linn Cos. (Biol. Survey) ; Montgomery 

 Co. (R. D. Lindsey) ; Wyandotte Co. (G. D. Hanna). 



11. Tylobolus uncigerus (Wood). 



Sijirobohts iDicigeriis Wood. Proc. Phila. Acad., 1864, p. 15. 



Tylobolus uncigerus Cook. Harr. Alaska Exped., vol. VIII, p. 



67 (1904). 



Under the name Spirobolus uncigerus, this species is recorded from 



Shawnee county by Cragin. Other recorded localities for this species are 



restricted to California and Oregon, so I do not believe it occurs in Kansas. 



Order ZYGOCHETA. 

 Family PARAJULID^. 



12. Parajulus diversifrons (Wood). 



Julus diversifrons Wood. Proe. Phila. Acad., 1867, p. 43. 

 Parajulus diversifrons Bollman. Bull. 46, U. S. Natl. Mus., p. 

 119 (1893). 

 Some of the specimens referred to this species are females, and doubt- 

 fully P. diversifrons, but each locality is represented by well-defined males.
