Figure 30. — Tachygonus femoralis, 

 new species, X5. 



Posterior femora much thickened (which characterizes the species), 

 constricted at the apex, bearing small tubercles and long white hairs 

 basally, and brown hairs apically; femoral teeth placed as follows: 

 On the inside a large one at about apical fourth, and two very small 

 ones clistad of it ; on the external side are two short ones of which the 

 more distal is fairly large and opposite the large tooth on the internal 

 side, the next one (proceeding toward base of femur) reduced nearly 

 to a tubercle, this followed by three others of which the second is 

 well developed on the left femur but much reduced on the right.
