DESCRIPTION OP THE SPECIES. 291 



its wings are neither as equally broad, nor as obtuse, as those of 

 the species united in the genus Icterica, that species differs als 

 in the absence of bristles upon the third vein.

Yellowish-gray ; head and feet saturate yellow ; the femora black, a con- 

 siderable portion at their tip in the male, a still more considerable one 

 in the female, yellow ; edge of the mouth very much produced, proboscis 

 geniculated, wings sparsely reticulate, the black stigma without pale 

 drops. Long. corp. 0.09 0.1, 9 cum terebra 0.11 0.12; long. al.

Observation 1. The saturate yellow coloring of the apex of 

 the femora in the male has a rather considerable, but at the 

 same time variable, extent; in the female, the yellow sometimes 

 occupies so much space, that the blackish color remains visible 

 at the basis of the femora only. Females with the femora as pale 

 as that, mentioned by me in the first part of these Monographs, 

 seem to be rare, as among the numerous specimens of my collec- 

 tion that single one only is to be found. 



Observation 2. To recognize the present species in the Acinia 

 picciola Bigot is not possible. Nevertheless the synonymy is not 

 doubtful, as, through the kindness of Mr. Gundlach, I have been 

 put in possession of numerous typical specimens. It is to be 

 regretted that Mr. Bigot has given the species a name which 

 cannot possibly be admitted, unless names like littlella, petitella, 

 kleinella for any small species were likewise tolerated. 



Observation 3. The strongly produced oral edge and the 

 strikingly geniculated proboscis, with its very much prolonged 

 flaps, reaching backwards as far as the mentum, define this 

 species as an Ensina. As soon as exotic species are taken in 

 consideration, this genus cannot be maintained within exactly the 

 same limits which I defined for it in my Monograph of the Euro- 

 pean species. A part of the species, which I placed there under
