 The accompanying Fig. 1 represents the arrangement 

 of these veins, which nearly resembles that in ]\Ir. E. 

 Doubleday's genus. (See Fig. 3 copied from his figure.) 



My opinion of the real nature of these veins differs, how- 

 ever, somewhat from that of Doubleday. In my view of 

 the subject we have a simple costal vein (1), a subcostal 

 vein (2), with only two branches (2a and 2b), a rudi- 

 mental discoidal vein (3), with its two upper and lower 

 discoidal veinlets (2b* and 4c*):i:, a median vein (4), with 

 its three ordinary veinlets (4a, 4b and 4c), a sub-median 

 veinlet (5), and an anal vein (6). In this view the smaU 

 space indicated by f preceding the origin of the third 

 branch of the median vein must be regarded as composed 

 of portion of the third median branch and portion of the 

 lower discoidal veinlet united together — a condition, how- 

 ever, found in very many Lepidopterous wdngs. The 

 only difference between the wings of the two genera con- 

 sists in the upper branch of the subcostal vein (2a) arising 

 nearer the base of the wing in Himantopterus , which 

 causes the discoidal cell to be less pointed in this genus 

 than in Thy mar a. 



Fig. 2 represents one of the tippets of the thorax of 

 Himantopterus, proving its real Lepidopterous character.

% I have elsewhere expressed the opinion that these two branches are 

 respectively portions of the subcostal and median systems, and hence have 

 lettered them thus rather than 3a and 3b.
