6. A. duzeei Bergroth. 



Proc. Ent Soc. Wash., ii, 333, 335, 1892. 



Dark brov^^n, brightly variegated with yellow ; length 6-6. y mm. 

 Recorded from Massachusetts, New York, etc., but not yet taken 

 in Connecticut. 



7. A. implanus Parshley. 



Trans. Amer. Ent. Soc., xlvii, 45, 1921. 



This species, which has often been confused with duzeei, is to be 

 distinguished by its thicker antennae, higher scutellar margins, etc. 

 Brown, with yellow markings, length 5.8-6.3 mm. Not yet found 

 in New England, though it occurs in eastern Canada, Pennsylvania, 

 etc. 



8. A. proboscideus Walker. 



Cat. Hem.-Het. Brit. Mus., vii, 35, 1873. 



Light, or rarely dark, brown, with very variable paler markings ; 

 length 6-9.7 "^"^- This is one of the most variable species of the 

 genus, but specimens can usually be determined without doubt by 

 the characters given in the key. A. hubbardi Heidemann is a 

 synonym. It is recorded from several of the New England states, 

 but seems to be confined to boreal conditions. 



9. A. basalis Parshley. 



Trans. Amer. Ent. Soc, xlvii, 54, 1921. 



Brown, with paler markings ; length 7-8.3 mm. Closely related 

 to the preceding. Known from Maine, New Hampshire, and 

 New York. 



10. A. censors Parshley. 



Trans. Amer. Ent. Soc, xlvii, 56, 1921. 



Grayish brown, with obscure darker and lighter markings; 

 length 7.6 mm. Known from one specimen only, taken many 

 years ago in Massachusetts. 



11. A. similis Say. 

 Het. New Harm., 28, 1832. 



Pale to dark brown, third antennal segment pale; length 

 5-8.5 mm. A very common and variable species, especially dis- 

 tinguished by its short second antennal segment. The variety 

 centriguttatus Bergroth has the third antennal segment con- 

 colorous.
