THE CANADIAN ENTOMOLOGIST. 199 



Head about as long as the pronotum in the middle, and distinctly longer 

 than broad, longitudin.ally impressed at the sides with a small tubercle a 

 little in front of and within the strongly-prominent substylated eyes, apical 

 ])rocess parallel from the apex to near the base, reaching the middle third 

 jiart of the second antennal joint, antenniferous spines a little divergent, 

 with a small tooth on tlie outer margin, antennt^ slender, almost filiform, 

 second joint distinctly shorter than the head, longer than the third and 

 fourth joint together, very slightly incrassated at the apex, fourth joint a 

 little longer than the third, rostrum reaching to or a little beyond the 

 middle of the mesosternum. Pronotum more than twice as broad as long 

 in the middle, dilated on the sides, with the greatest breadth behind the 

 middle, sinuated at base in front of the scutellum, lateral margins obtusely 

 angulated, remotely and bluntly dentate, antero-lateral and posterolateral 

 margins almost straight, disk with the usual six keels, the two inner keels 

 reaching the apical margin, approximated before the middle,external keels 

 much abbreviated, not reaching the middle, median keels reaching the 

 middle of the fore half, ending in a tubercle. Scutellum with a central 

 tubercle, lateral margins raised, nearly parallel towards the base. 

 Hemelytra in the male extending a little beyond the middle of the dorsal 

 genital segment, in the female only reaching the base of this segment, 

 lateral margin of corium ampliated near the base, membrane grayish, with 

 more or less distinct small fuscous spots. Abdomen rather strongly 

 rounded on the sides, lateral margin of connexivum distinctly subangularly 

 prominent just before the apical angles of the segments. Length, c^ , 6 

 mm.; 9 5 6.5 mm. 



Males : Apical lobes of genital segment broad, rounded, with some 

 short and blunt marginal teeth. 



Female : Fifth ventral segment a little shorter in the middle than at 



the sides, apical margin straight in the middle, apical angles extending 



beyond the middle of the median lobes of the sixth segment, these lobes 



taken together about as broad at apex as their length, apical angles of 



sixth segment not reaching the apex of the first genital segment, which is 



very short, four times shorter than the middle the sixth ventral segment, 



second genital segment but little shorter than the first, hairy, protruding 



between the apical genital lobes, the outer margin of which is rounded, 



with a few obtuse teeth.

Allied to A. similis. Say, and Hiibbardi^ Heid., but it is more broadly
