This species is a comparatively recent adventive in Hawaii, 

 having first appeared there, according to Perkins,** about 1900. It 

 was first recorded from the Islands in 1906, by Kotinsky, as 

 A. crcuaticcps Blanchard,*"^ identified as that species by Swezey and 

 confirmed by Bruner. Swezey has later given interesting data as 

 to the life history of the species.**^ 



At the time those records were published, Bolivar's ''Notas 

 sobre los Pirgomorphinos, X, Subfam. Atractomorphinae,"*' in 

 which auibigna was described, had probably not been seen by either 

 Swezey or Bruner. 



Comparison of the present material with a series of seven males 

 and ten females from Shanghai, China, in the Hebard Collection, 

 shows conclusively that but one species is represented, the Shang- 

 hai topotypes agreeing closely with Bolivar's description, except 

 that the type is apparently a very large individual. F. W. Terry,*^ 

 in his "Notes on Some Insects Observed in South China which 

 are also Common in Hawaii," found the species of Atractomorpha, 

 which was common about Hong Kong and Kowloon, the same as 

 the Hawaiian insect, and recorded it as crenaticcps. Though 

 closely related, ambigiia may be distinguished from crenaticcps and 

 siinilis (Bolivar) by the distinctly weaker pronotal carinae and 

 the presence on the pronotal lateral lobes, mesad near the caudal 

 margin, of a small area, which is smooth and colorless. 



The species is known only from the islands of Oahu and 

 Kauai, having been first recorded from Kauai as crenaticcps by 

 Swezey in 1918.*^
