518 EHOPALOCEEA. 



It is very like Aides epitus (Cram.), from which, however, it differs in the shape 

 of the silvery marking of the secondaries beneath, as well as in the form of the 

 brand, &c. For the genitalia of the male, see Tab. XCVI. fig. 31. 



b. Brand on the primaries of the male formed of four pieces.

Of this insect we have seen five males and one female. It closely resembles the 

 South-American X. chalestra (Hewitson) (= Goniloba concors, Herr.-Schaff.), but 

 the secondaries are without the inner spot above, and it also has more of the metallic 

 green colour on the upperside of the body and at the base of the wings. We figure 

 a male from Bugaba ; likewise the fore wing to show the position of the brand 

 (Tab. XCVI. fig. 34), and the genitalia, for which see Tab. XCVI. fig. 35. 



TELLES, gen. nov. 



Papilio arcalaus, Cram., a peculiarly coloured Tropical- American insect, that just 

 enters our limits, is taken as the type of this genus. We know of no other species 

 that can be satisfactorily associated with it. Telles is perhaps nearest allied to 

 Thespieus, but the primaries are without trace of a brand in the male, as well as being 

 much less produced at the tip. 



The antennae are about half the length of the costa, and have a rather short club, 

 terminating in a long crook. The third joint of the palpi is very short and almost 

 concealed. The primaries are moderately elongate, blunt at the tip, arched on the 

 costa towards the base, and slightly concave on the outer margin ; the cell is less than 

 two-thirds the length of the costa ; the discocellulars are strongly oblique, the upper 

 one more than twice the length of the lower, the latter being a little shorter than the 

 third median segment ; the first branch arises before the middle of the median nervure, 

 the second not far from the lower angle of the cell. The secondaries are produced 

 at the anal angle, extending slightly beyond the apex of the abdomen ; the disco- 

 cellulars are strongly oblique, the lower one well defined for half its length. The 

 body is very robust. The middle tibiae are spined, and the hind tibiae have two pairs 

 of long spurs. There are no secondary sexual characters visible on the wings.
