Genus XXIV. MOCHLONYX, Loew. 



In this very peculiar genus the legs differ from those of all 

 other members of the family in having the second tarsal joint 

 longer than the first, instead of the latter being, as in the other 

 genera, one of the longest in the entire appendage. 



Another singular point is that, while the imagines much 

 resemble those of Corcthra, the larvas are more like those of 

 Gulex. 



Mr. Theobald, to whom I am indebted for the following 

 diagnosis, is, I understand, of the opinion that in reality but one 

 species, Mochlonyx velutinus, Euthe, can be considered as 

 established, and that the others are but synonyms. 



In this genus the proboscis is much shorter than the head and thorax, 

 but rather longer than the head. Palpi four-jointed, and twice as long 

 as the proboscis ; antenna; fifteen-jointed, the last two joints longest and 

 verticillate ; joints increasmg in size from base to apex. Tranverse veins 

 rather more distant from the margin than m Corethra, otherwise much 

 the same, the veins being very delicate ; the branches of the forked veins 

 more than twice as long as their stems. Ungues large, wth a distinct 

 accessory tooth.
