Hab. In Bogota. B.M. 



This is one of the most elegant species in the family. It 

 is very slender, especially in the mesothoracic portion of 

 the body. The head is oblong and polished ; the eyes large, 

 as well as the three ocelli. The autennse are long and 

 straight, about 24-jointed, the joints being remarkably 

 long. The anterior half of the body is of a rich fulvous 

 colour ; the legs rather paler, with a slight greenish tinge. 

 The prothorax is rather irregular on its upper surface, and 

 the mesothorax is marked by an impressed line down the 

 whole of its length. The tegmina are small, oblong, with 

 the middle of the carina but slightly elevated ; they are 

 fulvous yellow, with the inner margin marked with three 

 rows of small black spots occupying the areas between the 

 transverse yellow veins. The wings are large, of a beau- 

 tiful rosy hue, with darker rosy longitudinal veins ; the 

 costal area rich yellow, with fulvous longitudinal veins ; 

 the fore margin tinged with green, and the hinder margin 

 with a brown dash, intersected by the pale longitudinal 

 veins ; the principal vein is not furcate, but it unites before 

 reaching the apex of the wing with the next vein, and this 

 united portion again unites close to the tip with the fol- 

 lowing vein. The legs are very slender and simple ; the 

 basal joint of the tarsus about as long as the following joints 

 united. The abdomen is long, cylindrical, brown, and 

 polished ; the three terminal joints are short, and termi- 

 nated by two slender, straight, porrected styles ; the ovi- 

 positor is straight, scarcely swollen, and reaches to the 

 extremity of the ninth dorsal segment.
