Hab. Illinois. White Mountains, IS T . II. (Ostcn-Sacken.) 

 Observation 1. — I believe I possess also the ? of this species 

 in a single specimen, and would not doubt it at all if the tip of 

 the hind tibiae did not show a rather distinct brown coloring, 

 which is not perceptible in the £ . All the other marks in the 

 9 are precisely as they might be expected in the 9 of the above 

 described g . The fore tarsi are blackened from the tip of the 

 first joint. 



Observation 2. — D. splendidus differs from D. subciliatus not 

 only by being much brighter, but particularly by the much less 

 perceptible lengthening of the fore tarsi and by the much -longer 

 and much closer ciliation of the hind femora of the male.
