TALLDES. 633 



Hew.) is without a brand in the male. We here retain the generic name Talides 

 solely for the branded forms, one only of which, the type, enters our limits. 



The antennae and palpi are formed as in Perichares. The primaries are pointed ; 

 the cell is much less than two-thirds the length of the costa ; the discocellulars are 

 moderately oblique, the upper one more than twice the length of the lower ; the lower 

 radial is greatly depressed at the base ; the first branch arises a little before the middle 

 of the median nervure : the second near the lower angle of the cell ; the third median 

 segment is short. The secondaries are produced at the anal angle ; the discocellulars 

 are very oblique, the lower one distinct. The body is very robust. The middle tibiae 

 are furnished with short spines, the hind tibiae with two pairs of spurs. The primaries 

 of the male have a conspicuous oblique brand extending from the base of the second 

 median branch to a little before the middle of the submedian nervure. 



We figure the fore wing of a male of T. sergestus, see Tab. CVI. fig. 23.

Linnaeus quoted Clerck's figure of this species under the name Papilio thrax, but it 

 evidently applies to the Tropical-American insect subsequently described by Cramer 

 as P. sergestus. P. thrax is a well-known eastern species. 



This fine insect is not uncommon in Central America, ranging as far north as the 

 Mexican State of Vera Cruz. Both sexes vary a good deal in the colour of the under- 

 side of the secondaries. 



The female, described by Cramer under the name of P. sinon, has much larger 

 spots on the primaries and an additional one near the submedian nervure. Some 

 males have the spots on the primaries nearly as large as in the females, and the yellow 

 submedian spot present (figg. 25, 26). For the genitalia, see Tab. CVI. fig. 24.
