The species of this genus have scarcely been collected in this country. 

 Up to the time of Wood's principal publication in 1865 two species had 

 been described, neither of which were known to him. Wood described 

 a third species in 1867 and Meinert a fourth in 1S85. C. hyalina sent by 

 Mr. Bollman is all I have seen. If the descriptions can be depended 

 on they ought to be distinguished by the following table : 



A. — Antennae 19-jointed asperipes Wood.

B Third joint of anal legs armed with five spines hyalina Say 



Anal legs unarmed C

8 The genus Theatops has had a strange history and after all its vicissitudes may 

 as well be consigned to oblivion. It was first described by Say (1S21) as Cryptops 

 postica from Georgia and East Florida. Newport in 1844 established the genus 

 Theatops on type specimens sent by Say to Leach and deposited by him in the British 

 Museum. Newport says "it approaches Cryptops, but differs from that genus in the 

 distinctness of the ocelli and in the possession of the labial teeth." Gervais in the 4th 

 volume of Apteres (1847) re-unites it to Cryptops and yet adds: "On devra tres- 

 probablement la reunie aux veritable Scolopendres." Wood in 1862 and later in 1865 

 quotes Newport's description, stating that he never saw a specimen of it. Latzd 

 (1880) in the first part of his "Myriopoden der Oesterreichisch-Ungarischen Monarchic" 

 makes it a probable synonym of Scolopendra, while Kohlrausch (1881) enumerates it 

 as a valid species of Theatops in his "Gattungen unci Arten der Scolopendriden." It 

 thus appears that Say and Newport are all who saw specimens and their statement- 

 are opposed to each other in regard to the position of the eyes. It will probably never 

 appear again ; at least is it not necessary to include it in future lists.
