wing very slightly; a very small, but deeply colored spot exists near 

 the hind margin of hind wing. Pterostigma grayish white, marked with 

 fuscous black. 



Length of body, 33 mm. ; fore-wing, 38 mm. ; hind-wing, 36 mm. ; an-

I received a male specimen from my friend, Mr. T. Esaki, 

 who captured it on the night of August 24, 1911, when he was 

 traveling through the northern part of the main island of 

 Japan. He told me that the specimen had flown in at the 

 window of the train by which he was traveling near the town 

 of Taira, attracted by the light. 



This species is allied to Formicaleo contubernalis McL., 

 but, as stated above, its vertex is without spot, while that of 

 contubernalis has numerous small orange-yellow spots ; hind 

 leg of the former with strong black spines, while that of the 

 latter has long white hairs only ; pterostigma of the former Is 

 distinctly marked with fuscous black, and the costal trans- 

 verse veins mostly black, while those of the latter are indis- 

 tinct and wholly pale. Moreover, the markings of the ab- 

 domen readily separate the two, because in the present species 

 the second segment is without spot except that of the hind 

 margin, and the third segment has one broad band in addition 

 to that of the hind margin, while both the segments of con- 

 tubernalis have a narrow interrupted dorsal orange-yellow 

 line, and the sides of the third with the same colored spots. 



With the above differences, I doubt not that, although allied, 

 the two are distinct.

Face above the epistome blackish brown, shining ; an obscure and 

 irregular impressed spot in the middle between the antennae; mouth 

 and a ring around eye yellowish, the latter often interrupted. Maxillary 

 palpi thin, fulvous brown, the last joint cylindrical and notched on tip; 

 labial palpi about two and a half times the length of the maxillary, ful- 

 vous brown, the last joint fusiform, and its conical tip notched. An- 

 tennae dull black, as long as the thorax; tip clavate and flattened, the 

 very extremity little curved ; a yellow ring exists around the two basal 

 joints. Vertex blackish and transversely ovoid, elevated, and divided 

 by a slight median impression ; on top with irregular black spots ; hind 

 margin lighted with yellowish fuscous ; in the male, the median impres-
