The surface of the body is never polished in the male, always 

 being dull and at times almost velvety in appearance. In the 

 female sex this condition is present, but not as a rule, the majority 

 of the individuals of that sex having the surface weakly polished. 

 The males show a very appreciable amount of individual variation 

 in the lamellate development of the ventro-external margin of the 

 caudal femora, as well as in the number, disposition and size of the 

 spines on the same margin. 



The species is known to range from the vicinity of the city of 

 New York to northeastern Georgia; in addition to these given above, 

 the only definite record of its occurrence in the southeastern States 

 is that from Raleigh, North Carolina (Brimley).

The species virgatipes, when described, was compared with secretus 

 and varicator, with which it has, however, no relationship. This 

 erroneous comparison was due to Scudder's key, which ran adults 

 to the vicinity of the above-mentioned species, while latibuli was 

 placed by him in another section, in which authentic material 

 examined by him at that time, and now before us, would not fall. 

 The type (male) of virgatipes is in the instar preceding maturity, 

 but the allotype (female) is fully adult. It is evident that the full 

 development of the caudal spurs and calcaria is not acquired until the 

 adult condition is reached, these being relatively shorter in the 

 nearly adult specimens than in the mature individuals. There is 

 also some individual variation in the length and development of the 

 spurs and in the length of the different calcaria. The more subdued 

 general coloration of the virgatipes material is in part due to dis- 

 coloration. The color pattern is seen to vary greatly in intensity 

 and consequently in the relative extent of the pale and dark areas. 



The species has been reported from "gopher" holes at Crescent 

 City and Enterprise, Florida, and from "Georgia, " in addition to the 

 localities mentioned above.
