Hah. Panama, Chiriqui. 



Three specimens seen, one of which, marked " type " 

 by Gorham, is a male. This insect is extremely Uke D. 

 opacus, but is separable therefrom by the broader antennae 

 and less elongated basal joints of the posterior tarsi of 

 the male, and the much less acutely serrate intermediate 

 antennal joints of the female. The colour, sculpture, and 

 vestiture of the prothorax and elytra are precisely similar. 



3. Dromanthus nitidicollis.

^. Antennae with joints 5-10 very broadly widened, acute at 

 the inner apical angle, 11 elongated, narrower, and yellow; posterior 

 tarsi with joint 1 curved and produced at the inner apical angle 

 into a long slender process which reaches as far as the apex of 2, 

 2 also curved and elongated. 



Hab. Panama, Bugaba. 



Described from two males. This insect has the posterior 

 tarsi of the male formed as in the same sex of the Mexican 

 D. opacus, from which it is separable by the yellow apical 

 joint of the antennae and the flatter and more shining 

 prothorax. The antennae are less widened than in D. 

 laticornis, ^, and the posterior tarsi differently formed. 

 The tarsal structure is not mentioned in the description 

 or shown in the figure of D. nitidicollis.
