MANTIDAE AND PHASMlDAE OF PANAMA 



in male. Caudal metatarsus nearly twice combined length of 

 succeeding joints. 



The cephalic tibiae are dark brown, distinctly tri- annulate 

 with buffy, these colors being carried on to the distal portion of 

 the femora, adjacent when the limbs are flexed, and contrasting 

 strongly with the remaining internal portions of the femora 

 and coxae, which are rich tawny. The other limbs are also 

 decidedly annulate. This is also true for the additional female 

 and immature male at hand. The adult males, however, have 

 these features less strongly defined, the markings on the cephalic 

 femora and tibiae being almost completely obscured.

Though the only Colombian specimen before us is immature, 

 the series at hand agrees so closely in all charactei\s of real 

 specific value that we feel fully justified in indicating the above 

 synonymy. This series, however, shows the species to be subject 

 to very decided size and color variation. As a result the very 

 dark examples have a decidedly different facies from the i)aler 

 individuals, while in the smallest specimens the tegmina are not 

 only reduced in proportion but show no widening meso-ilistad.
