The pale base color is more orange-ochraceous in some individuals 

 than in others, the extremes being pale clay color and burnt sienna. 



This species and lapidicola are very closely related, the females 

 particularly being extremely hard to separate. Of the few differ- 

 ences shared by both sexes may be mentioned the narrower medio- 

 longitudinal pale bar in lapidicola, which also has a greater irregularity 

 of its margins, and a frequent breaking up of the dark lateral bars. 

 The males of the two species can, in addition, be separated by the 

 more robust caudal femora in the present species and the form of the 

 supra-anal plate, which has the distal margin submembranous in 

 latens and chitinous in lapidicola, the plate also more elevated disto- 

 dorsad in lapidicola than in latens. 



The immature specimens of latens listed above have the thoracic 

 pattern essentially as in the adults. 



Ceuthophilus sallei Scudder. 



De Funiak Springs, 126 Florida, 1 d\ 1 9, 1 juv. 9, [Cornell Univ.]. 



We have compared these specimens with a paratype from New 

 Orleans and find no important or constant differences. The color 

 pattern is seen to vary in intensity to such a degree that occasionally 

 (in the adult female) the thoracic pattern is obsolete, although the 

 abdominal section is weakly indicated and the femoral pattern 

 typical, but not very decided. 



The authors' C. peninsularis, 127 from southern Florida, is a close 

 relative of this species, but just how close cannot be determined 

 until the female sex of the more recent form is known. 



The distribution of the species is here extended somewhat to the 

 eastward of the type and only previously known locality — New Orleans.

120 These specimens are merely labelled "Funiak, Fla. " but as there seems 

 to be no locality of that name, we feel little doubt of their reference to the well- 

 knOwn locality given above.

128 In Scudder's original series of C. neglectus, a specimen from Washington, 

 D. C, in the Bruner Collection, is listed. This record refers to the above speci- 

 men, which can be separated from the other paratypic females of neglectus from 

 the Bruner Collection, by the more slender caudal femora and the fewer (four 

 instead of five) teeth on the internal valves of the ovipositor.
