 the extremity of the abdomen.

De Haan (Orth. Orient, p. 131) and Burmeister (Zeitsch. 

 ii. 38) incorrectly consider this supposed species to be the 

 pupa of A. Japetus (spinieollis). 



The rudimental tegmina are 1£ line, and the rudimental 

 wings 3| lines long ; the posterior tibiae have several spines 

 on the outside near the base ; and the anal styles are as 

 long as the preceding segment, broadly ovate, each with 

 an erect thin ovate lobe as long as the stvle itself.

According to De Haan (Orth. Orient, p. 131), this sup- 

 posed species is the pupa of A. Chronus (marginipennis) .

This species is remarkable for having the wings strongly 

 tessellated in both sexes, those of the female being scarcely 

 more than half the size of those of the male, and for the 

 minute size of the anal styles of the male. The body is 

 long and slender. The general colour is dark reddish 

 brown. The head of the male is wide, with large eyes, and 

 the three ocelli are distinct in both sexes ; the antennae in 

 the male are moderately long, slender, and finely setose, 

 about 24-jointed ; those of the female are much shorter, 

 but composed of the same number of joints. The meso- 

 thorax is armed along its upper surface with about six 

 pairs of small pointed tubercles, placed rather irregularly ; 

 and the lateral margins are also armed with a few smaller 

 ones. The tegmina are oblong-ovate, with the middle of 

 the central carina scarcely elevated. The wings are white,
