MTSCELUS.— OXTNETEA. 267 



strongly impressed, and in the yellow colour of the under surface being confined to the 

 base of the wings, the outer portion being darker and more rufescent. 



The genitalia of the male differ from those of M. belti in having the lower lobe of 

 the harpagones less acute and not nearly so strongly serrate ; they otherwise agree in 

 their general outline. 



AZONAX, gen. nov. 



In this genus the club of the antennae is comparatively slender as in Myscelus ; the 

 outer margin of the secondaries uniform, not dentated ; primaries somewhat produced, 

 the outer and inner margins subequal, the costa but slightly arched, upper discocellular 

 distinct, fourth submedian branch emitted considerably beyond the end of the cell as in 

 Microceris, subcostal branches widely apart, second and third median segments subequal ; 

 cell of the secondaries rather long, the second median branch emitted before the end of 

 the cell. Hind legs wanting.

Alia rufo-fuscis ; anticis maculis undecim hyalinis notatis, una quinquepartita infra medium costse (punctoque 

 infra earn), una extra earn, una bifida ad costam, et quatuor ad apieem, maculis rufescentibus extra omnibus 

 quoque ornatis; posticis macula ad basin albida, macula magna alba byaliua ante medium, altera 

 ad marginem externum propriore fascia rufa pallida, infra eas maculis quinque notatis, duabus exterioribus 

 hyalinis et maculis, alteris indistinctis brunneis limbatis : subtus ut supra, alis ad basin griseo-albis, 

 margine externo saturate brunneo griseo-albo irrorato : posticis maculis pallidis flavidis ad medium costae. 



Hah. Nicabagua (Mus. Brit.). 



The only specimen of this peculiar species is the type now in the British Museum. 

 In his original description Hewitson omitted to give the locality whence his specimen 

 was derived l ; but it is labelled Nicaragua, as stated by Mr. Kirby inh is catalogue of 

 the Hewitson Collection 2 . It probably originally formed part of Belt's collection.

This genus was founded by Felder upon two specimens which he called 0. semihyalina ; 

 these have since proved to belong to two separate species, which are now known as 

 0. semihyalina and 0. felderi ; to these a third, 0. hopfferi, has since been added. Of 

 these, the last named is the only one which certainly occurs in our country, though 

 0. semihyalina has been attributed to Mexico. Bis annulatus also belongs to this 

 genus if it really differs from 0. hopfferi. 



The club of the antennae is more pointed in this genus than in Pyrrhopyge or any of
