98 ANTHOMYZA TIRESIA. 



conidse. They certainly bear a very striking general 

 resemblance to the Heleconian butterflies, and the 

 analogy must be admitted to be close. 



A. Tiresia measures three inches and three-quar- 

 ters between the extremities of the wings : the upper 

 pair are deep black with two broad, opaque, deep 

 yellow bands lying obliquely across the surface, 

 one near the middle, the other, somewhat abbrevi- 

 ated, towards the apex, and a patch of the same 

 colour on the hinder border before the middle ; the 

 base with a few small white spots, and a remote 

 series of the same near the exterior margin and 

 parallel with it. The hinder wings are yellow, with 

 a broad black border bearing a marginal row of 

 white spots : anterior part of the thorax spotted 

 with white ; abdomen brown. 



A. heleconides. Colours and the mode of their 

 distribution precisely as in the preceding species, but 

 the yellow paler, approaching to yellowish-white, 

 and the bars and spots transparent. Expansion of 

 the wings three inches. Swainson's Zool. Blus., 

 pi. 124, fig. 2.
