Ky.); Underwood, Ent. Amer., 65, 1887. 



The study of a large series of specimens of the genus Cryptops 

 convinced me that all the species of Gryptops described from North 

 America belong- to a single species hyalinus Say. 



I have questioned the Cryptops milbcrti of Gervais, because the 

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

 character is contrary to the (rue definition of Crypt-ops, and I am in- 

 clined to think that either Gervais had an abnormal specimen or that 

 his observations were incorrect. 



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

 number of antenna! 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. 05, 1887, Dr. Underwood says the last pair of legs 

 of sulcatns 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 G. hyalinus. 1 have examined speci- 

 mens of this species from the following States: Maryland, Pennsyl- 

 vania, Indiana, Tennessee, North Carolina, Florida, Indian Territory, 

 and Arkansas, where it is very common. 



26. Theatops spinicaudus (Wood). 



Abundant from Little Rock to Ultima Thule. 



27. Scolopendra heros (Jirard. 



Two adults were obtained at Little Hock, several young at Murfrecs- 

 boro and Muddy Fork. 



28. Scolopendra woodii Mcinci t. 



A single specimen was caught at Donaldson. 



29. Scolopocryptops sexspiiiosus (S:i\ I. 



Common at all points; these specimens are of a darker shade than 

 northern or eastern examples. 



30. Heiiicops fulvicoriiis (Meinert). 



A single specimen was obtained at Little Hock near the, Deal' Mute 

 Asylum. This is a, European species, and the, only other recorded 

 North American locality is Mount Lebanon, New York.
