CAMPTOPLETJEA.— DIPHOKIDAS. 423 



The male genitalia have the tegumen ending in a short depressed hook, from the 

 base of which on either side a short pointed lobe arises directed forwards and upwards: 

 the harpes are asymmetrical ; the right side ends abruptly, and carries a short, strong, 

 dentate process extending upwards ; on the proximal side of this, on the dorsal edge, is 

 an irregularly serrate lobe ; the left side is considerably produced and rounded at the 

 end, near which on the dorsal edge are a few serrations and then after an interval a 

 series of strong recurved teeth.

This Camptopleura seems distinct from C. thrasybulus, the markings of the wings 

 being more regularly linear and not so diffused as in that species ; nearly all of them, 

 too, are uniform in colour and not in rings, as in the allied form. The few specimens 

 we possess were selected without much difficulty from a large series of C. thrasybulus. 



DIPHOKIDAS, gen. nov. 



This genus, of which D. phalcenoides (Hiibn.) may be considered the type, differs 

 from Camptopleura in having rather longer primaries, the outer margin of which is 

 much rounded ; there is no costal fold, the discocellulars are rather more oblique. 

 But the chief difference is in the palpi, the terminal joint of which is long, thick, and 

 drooping. The legs present no differences, the hind tibiae being tufted and bear two 

 pairs of spurs. 



The male genitalia have asymmetrical harpes, as is the case in Camptopleura and 

 Gorgythion, and to some extent in all these allied genera. 



I), phalcenoides and D. palpalis are the only members of the genus we have as yet 

 recognized. The former spreads over nearly the whole of Tropical America from 

 Southern Mexico to Paraguay, and the range of the latter is included in the southern 

 portion of this area.
