The study of a large series of s[)ecimens of the genus Cryptops has 

 convinced me that all the species of Cryptops described from North 

 America belong to a single species — hyalimis Say. 



1 have questioned the Cryptops milberti of Gervais, because the 

 author states that the spines of the last pair of feet are absent. This 

 character is contrary to the true definition of Cryptops and I am inclined 

 to think that either Gervais had an abnormal specimen or that his ob- 

 servations were incorrect. ' 



Asperipes Wood, has been separated from the other species by the 

 number of antennal joints (19), which he assigned to his species, but as 

 the number of joints has recently been found to be variable it is not a 

 true character upon which species can be based. 



In Ent. Amer., 65, 1887, Dr. Underwood says the last pair of legs 

 of sz^/c<7/«5 Meinert, are unarmed, as in milberti Gervais, but in this he 

 is mistaken, for, in his generic description Dr. Meinert states that the last 

 pair of legs are armed with a definite number of spines. 



Considering this state of characters, I believe that all the described 

 species should be united under C. hyalinus. I have examined specimens 

 of this species from the following States : Maryland, Pennsylvania, 

 Indiana, Tennessee, North Carolina, Florida, Indian Territory, and Ar- 

 kansas, where it is very common. 



26. Theatops spinicaudus (Wood). 



Abundant from Little Rock to Ultima Thule. 



27. Scolopendra heros Girard. 



Two adults were obtained at Little Rock, several young at Murfrees- 

 boro and Muddy Fork.
