ities and the average size southward is greater, but the Florence 

 series is sufficient to show that the individual size variation is 

 very great. 



As with glaberrimum this species occasionally develops a red- 

 dish coloration of the head, as rich and decided as in the most 

 extreme individual of the larger species, while other specimens of 

 militare have a vertical facial bar ranging in color from pale red- 

 dish to walnut brown, which condition is quite similar to that 

 frequently found in 0. concinnum. This facial marking occa- 

 sionally spreads out laterad over the ventral portion of the genae 

 and again in some few specimens the infra-ocular and infra- 

 antennal regions are quite blackish. 



The number of spines on the distal portion of the ventro-ex- 

 ternal margin of the caudal femora either varies from one to two 

 or the margin is unarmed. A count of twentj^ specimens shows 

 the following results:
