species described by Say. However, a recent examination of type of 

 Theatops by Mr. B. limes Pocock has proven that Newport was wrong 

 as to the specimen having occelli. Taking this into consideration the 

 synonomy of this species must stand as indicated above and the name 

 as Theatops posticus (Say). 



*16. Geophilus rubens Say. Journ. Acad. Nat. Sci. Phila., 113, 1821. 

 Geophilus cephalicus Wood. Journ. Acad. Nat. Sci. Phila., 44, 1862. 



On account of the difference of coloration assigned by Say and New- 

 port to this species, I do not feel sure of my identification. Say says 

 his specimen is " red," and this would prevent me from identifying 

 rubens with cephalicus ; but Newport, who has examined and described 

 Say's type, which is in the British Museum, concerning the coloration 

 says: " Saturate aurantiacus, liuea mediana duplici nigra e segmento cor- 

 poris primi ad pcnultimum ductal 



When we take into consideration this peculiar pattern of coloration, 

 the number of pairs of legs (50), and the length of anal pair (hardly 

 exceeding the preceding), there is only one known species with which we 

 can possibly identify the rubens of Say, and that our common and 

 widely distributed G. cephalicus Wood. 



That Say's species is a true Geophilus is indicated by the following 

 from his description: u segments with two longitudinal impressed lines, ," 



If Say had not mentioned this and no types of his species had been 

 preserved I would hardly hesitate to identify rubeus with the fulva of 

 Sager or the bothriopus of Wood. As it is I cannot see why we should 

 not consider rubens and cephalicus identical. 



17. Geophilus attenuatus Say. Journ. Acad. Nat. Sci. Phila., 114, 1821 {Southern 

 States).

 Schendyla? perforates McNeill. Proc. U. S. Nat. Mus., 325, 1887 (Pensacola, 

 Flo,.). 



Of the seventeen new species described by Say this one is the most 

 inaccurately described and the one which has given me the most 

 trouble in regard to its identification. 



Nevertheless when we take into consideration that there are only 

 three species (latro, bipuncticeps, and foveatus) found in or very near 

 the region in which Say collected, and compare them with Say's de- 

 scription of attenuatus, I have found that only one, bipuncticeps, agrees 

 in regard to the shape of body and the length of anal legs. 



Although most persons would consider attenuatus unidentifiable, 1 

 think, at least for the present or until more light can be thrown upon 

 Say's species, it is best to regard it the same as bipuncticeps. 



Besides the above seventeen new species Say has also noticed two 

 others — Fontaria virginiensis and iScutigera forceps.
