Santos Dias (1954-G) opines that (l) A. poematium is a sepa- 

 rate species, (2) A. schlottkei Schulze, T93^, might be a synonym, 

 and (3) A. faiai Santos Dias, 1951, definitely is a synonym. The 

 specificity of A. poematium is hardly convincing on the basis of 

 descriptions an^ illustrations, though there is a possibility 

 that comparison of specimens may provide yet unmentioned clues to 

 separate this morphologically from A. nut t alii . Breeding experi- 

 ments are also indicated. "" 



IDENTIFICATION 



A. nuttalli is similar to A. marmoreum in characters mentioned 

 under that species, except for the following: Males ; Size is 

 smaller, always less than 6.0 mm. long. Pale ornamentation of 

 the scutum is somewhat variable, but all specimens are like the 

 one illustrated in that the dark areas are less extensive and 

 more broadly separated from each other by light areas than they 

 are in A. marmorevim . 



Females ; This sex is also smaller than that of A. marmoreum 

 (body approximately 7.0 mm. long, 5.5 ram. wide; scutum about 3.2 

 mm. long, 3.3 mm. wide); the central pale scutal ornamentation 

 tapers to a narrow point posteriorly and is therefore very dis- ^ 

 tinctive.
