 terior tarsi not quite as long as the tibiae, and the first joint about 

 equal in length to the following three joints united. Tarsal claws 

 dissimilar, anterior ones cleft near the tip, middle ones slightly more 

 deeply cleft, and the posterior ones cleft near the middle, the teeth 

 about equal in width, and the inner one sometimes feebly turned
