ARTINES, gen. nov. 



We take Thracides mpitus^ Geyer, as the type of this genus, which will also include 

 a second species described below. Both insects have on the underside of the 

 secondaries a black patch surrounded by blue spots, outside which is an ochreous 

 ring. The male of T. wpitus has a conspicuous sagittiform brand, but this is altogether 

 absent in A. atizies. The long terminal joint of the palpi distinguishes Artines from 

 many of the allied genera. It agrees very nearly with Eutocus in the neuration of the 

 wings, as well as in the form of the brand, but the primaries are more elongate, and 

 the general coloration is very different, the structure of the genitalia also being peculiar. 

 The two species are confined to Tropical America, one only entering our limits. 



The antennas are more than half the length of the costa, and have an elongate club, 

 terminating in a long crook. The third joint of the palpi is long, erect, and pointed. 

 The primaries are moderately produced, arched on the costa, and blunt at the tip ; the 

 cell is less than two-thirds of the costa; the discocellulars are strongly oblique, the 

 upper one fully twice the length of the lower, the latter about as long as the third 

 median segment ; the lower radial is strongly depressed at the base ; the first branch 

 arises near the middle of the median nervure, the second a little before the lower angle 

 of the cell. The secondaries are rounded at the anal angle ; the cell is large and half 

 the length of the wing ; the discocellulars are very faint. The body is rather slender. 

 The middle tibiae are without spines, and the hind tibiae have two pairs of spurs. The 

 primaries of the male have a conspicuous sagittiform brand in the angle between 

 the second median segment and the first median branch (this being absent in A. atizies), 

 and the secondaries a fringe of long hairs along the upper edge of the abdominal fold 

 in this sex. 



We figure the fore wing and genitalia of a male of A. cepitus, see Tab GUI 

 figg. 47, 48.

We are indebted to Mr. J. J. Walker, R.N., for the only two Central- American 

 examples we have of this species, though, unfortunately, they are in bad condition and 

 both of the female sex. 



This insect is so like A. wpitus (Geyer) that we have long confounded the two in
