ORTALID^E EUXESTA. 165 



apex of the wing; it is also rather broad and reaches beyond the 

 fourth longitudinal vein; its connection with the third band near 

 the costa is rather narrow, so that the hyaline space, inclosed 

 between them, almost reaches the costa anteriorly. The last 

 section of the fourth longitudinal vein is gently arcuate and 

 slightly converges in its latter half towards the third longitudinal 

 vein (the figure does not give this quite correctly). 



Bab. Cuba (Gundlach). 



Observation. The Museum at Yienna contains a couple of 

 specimens taken in Cuba by Poppig, which differ, however, by 

 their distinctly smaller size, as well as by a somewhat different 

 picture on the wings ; all the four black bands are dissolved into 

 oval black spots, covering the veins, the portions of the bands 

 lying inside of the cells are crossed in the middle by gray stripes. 

 A closer examination, however, proves conclusively that these 

 specimens are incompletely colored ones of E. abdominalis. The 

 small size is probably due to the greater contraction in drying 

 of these unripe specimens.

Head brick-red or brownish-brickred ; the little stripes running 

 down from the vertex along the orbits of the eyes, as well as the 

 surroundings of the ocelli, of a shining steel-blue ; the whole 

 occiput blackish, with a whitish pollen. Front rather narrow, 

 with coarse hairs which are more dense on the somewhat whitish, 

 pollinose, lateral borders and more sparse on the remaining 

 surface. Antennae brick-red or yellowish-red, the third joint oval. 

 Face very much excavated ; with the exception of its lower, con- 

 siderably projecting, portion, it has a steel-blue reflection, but is 

 so thickly covered with a white pollen, that the bluish ground- 

 color is but little apparent. Clypeus rather strongly pro- 

 jecting, brownish-brickred, sometimes with a steel-blue reflection 

 on the sides. Thorax and scutellum of a rather dark, steel-blue 

 color, which turns somewhat to greenish-blue on the thoracic
