Subfamily Pyrgomorphinse. 

 Atractomorplia bedeli Bolivar. 



1884. Atractomorpha Bedeli Bolivar, Monografia de los Pirgomor- 

 finos. p. 69. 

 Thirty-two specimens, 9 males, 20 females, 3 uymphs. 

 Japan. Dr. H. C. Wood (3). 



Yokohama, Japan. Rev. H. Loomis (2). Rehu CoUection. 

 Kioto, Japan. Y. Hirase (27), Nos. 20 and 21. 

 One specimen from Kioto differs from the usual form in having 

 the Avhole superior aspect of the insect speckled with blackish- 

 brown instead of being uniform greenish. In the males the supe- 

 rior surface of the abdomen is bright carmine. 



Subfamily Locustinae (Acridiinm Auct.). 

 Oxya velox (Fabricius). 



1793. lOryllns] velox Fabricius, Entom. Syst., II, p. 60. 

 Nineteen specimens, 10 malei, 9 females. 

 Kioto, Japan. Y. Hirase. Nos. 18 and 19 (part). 

 As noticed by Brunoer,'^ this species, which usually passes as 

 hyla Serville, should bear the name given above. 



Oxya vicina Brunner. 



1893. Olxyal vicina Brunner, Rev. du Syst. des Orthopteres, p. 15'i. 



Thirty-one specimens, 16 males, 15 females. 



Yokohama, Japan. Rev. H. Loomis (4), Rehn Collection. 



Kioto, Japan. Y. Hirase (27), jSTos. 18 and 19 (part). 



This species is very closely allied to 0. velox, but differs in 

 several characters which, while not striking, are sufficient to differ- 

 entiate it with little, trouble. 



As ]?runner has simply given a key and a brief description of 

 this species, the notes made after a comparative examination with 

 specimens of 0. velox may be of interest. 



The ventral surface of the last segment of the abdomen in the 

 femah; of vicina is longitudinally bicarinate for the greater part of 

 its length; in velox this is smooth. The basal portion of the 

 mediastine area of the tegmina in the female of vicina is moder- 

 ately expanded, the margin gently rounded; in velox this section is 

 but^slightly more developed, but the greatest depth is caudal and 

 not median, while the margin is abruptly excavated posteriorly, 

 quite different from the gentle curve of vicina.
