II. Antennae very short, with a straight, or slightly curved, blunt club ; terminal 

 joint of the palpi long and erect ; hind tibiae with two pairs of spurs. 



A. Primaries without a brand in the male. 



APAUSTUS. 



Apaustus, Hiibner, Verz. bek. Schmett. p. 113 (1816) ; Watson, P. Z. S. 1893, p. 96. 



Watson gives Papilio menes, Cram., as the type of this genus, and he also includes 

 in it Aneyloxypha gracilis, Feld. ; this latter, however, has very differently formed 

 antennae and does not belong here. These two insects, as well as some other Tropical- 

 American forms, have the nervures on the underside of the secondaries, and also those 

 on the costa and apex of the primaries, yellow. 



The antennae are very short, less than half the length of the costa, with a moderately 

 stout blunt club. The palpi have a very long, erect, and slender third joint. The 

 primaries are elongate, blunt at the tip ; the cell is about three-fifths the length of 

 the costa ; the discocellulars are oblique, the lower one being much shorter than the 

 upper ; the lower radial is depressed at the base ; the first branch arises far beyond the 

 middle of the median nervure, the second from the lower angle of the cell ; the third 

 median segment is very short and almost in a line with the lower discocellular. The 

 secondaries are narrow ; the discocellulars are very faint. The body is long and slender, 

 the abdomen extending far beyond the anal angle of the hind wings. The hind tibiae 

 have two pairs of spurs. The primaries are without a brand in the male. 



A. menes just enters our southern limits. This insect is easily recognized by its 

 long narrow wings and short antennae ; it is doubtless of feeble flight.

Of this peculiar species there is a single specimen from Chiriqui in Dr. Staudinger's 

 collection, and we therefore include it in our fauna. We have no doubt that the 

 example figured by Cramer was in bad condition, as noted by Sepp, who states that 

 the larva feeds upon the rice-plant (Oryza sativa). For the genitalia of the male, see 

 Tab. XCII. fig. 22.
