vertex much deeper than the eyes ; behind each antenna a large, 

 hollow groove, both grooves separated by a sharp, wedge-shaped 

 carina ; the transversal line of the occiput if present, not visible 

 from above ; the small lateral impressions nearly wanting ; an- 

 tennae (apical half wanting, in King's figure 22mm. long) light 

 reddish brown, below paler ; first joint twice as thick as the rest, 

 keg-shaped ; second joint annular ; the following twenty-two joints 

 a little thinner, cylindrical ; third longer, fourth short, the following 

 successively longer ; mouth yellow, an indefinite transverse band 

 at the base and a brownish shade on tip ; labial and maxillary 

 palpi blackish with white articulations; mentum blackish before 

 the labium ; prothorax short, much narrower than the head, much 

 enlarged behind, dirty yellowish, with a brown band in the mid- 

 dle and one on each side ; thorax large, same color, no lines visi- 

 ble (in bad condition) ; abdomen short, above two maculose 

 yellow bands separated by a large black band ; a similar black 

 band on each side ; below reddish brown ; appendages pale yellow 

 with black hairs. Legs dark yellowish, long, with black villosity ; 

 first joint of tarsi as long as the others together ; claws thin, 

 black. 



Front wings, large, three times longer than broad ; front margin 

 straight to tip, hind margin curved so that the greatest breadth is 

 in the middle of the wing ; tip sharply pointed ; subcosta and 

 mediana yellow, the long space between them yellowish brown ; 

 the other veins are brown ; thirty costals to the small brown ptero- 

 stigma, which is enclosed only between two costals ; there is a 

 small round yellow spot connected with the subcosta in each of 

 the cells between the costals from the base nearly to the ptero- 

 stigma ; the extreme base of the hyaline wing, yellowish to the 

 hind margin. Hind wings very narrow, the two basal thirds yel- 

 lowish, followed by a brown band ; beyond it a little wider, white, 

 twice as long as the brown band, narrowed to the pointed tip. 



Westwood in his first diagnosis calls the pterostigma black, but 

 has later corrected it to brown. Probably his specimen was darker 

 than mine to judge from his figure in Duncan. King's figure 

 agrees with my specimen except that he describes a milk white 

 pterostigma before a blackish spot ; as my specimen is very pale 

 and probably the colors immature, the milk white is very little to 

 be seen. At least there is no doubt about the identity, as my 

 specimen is labelled by Klug himself, and the white pterostigma
