uniform, while the San Pablo specimen is of similar pattern but with 

 the tones paler. 



The new form was found on July 10-12, 1912, under exactly the 

 same conditions at Homestead and Detroit as was tenuescens, the 

 San Pablo specimen having been taken in the undergrowth of pine 

 woods,

A special trip to secure specimens of this striking species was made 

 to Loggerhead Key, where, with the kind assistance of Dr. Alfred G. 

 flayer, the Director of the Carnegie Marine Biological Laboratory, 

 we were able to secure the above interesting series. All were taken 

 from bushes of the bay cedar (Suriana maritima), to which, as shown 

 by Stockard in his paper on the habits of this species, ^^ the species 

 is there restricted. The adult females show the marked color 

 variations spoken of by Stockard, while the males vary only in the 

 extent to which the greenish of the limbs tinges the thoracic segments. 



Our series shows the following extremes in the length of the body, 

 cf 83.-93. mm., 9 (exclusive of the oviscapt) 114.-127.5. The oviscapt 

 varies considerably in length individually, the extremes, which are 

 in specimens of approximately the same general bulk, being 25.-29.5 

 mm. The Loggerhead Key nymphs represent three stages of 

 development. 



According to Dr. ]\Iayer, the species occurs on Bird Key and Garden 

 Key, the other islands of the Tortugas group. On Long Key the 

 single very immature individual was beaten from heavy key scrub. 

 The nearly half-grown male from Key West was found in the after- 

 noon, climbing up the trunk of a bush in a heavy tangle.
