correlated with a different claw-structure, the longer front claw 

 only being cleft in the species of the communis group, while here 

 those of both front and middle feet are cleft in the male, and 

 probably also in the female. The nearest ally of A. fallaciosa is 

 A. marginipennis^ but in that species the male has the claws as in 

 A. communis and the female as in A. fallaciosa. The present 

 species may be further distinguished from A. communis by a its 

 shorter and broader clypeus, bidentate front tibia, the obsolete hind 

 angles of the prothorax and, in the male, by the smaller eyes and 

 shorter antennal club.

p. 78. 



Pale testaceous, with the head between the eyes, a narrow 

 marginal line entirely encircling each elytron and a humeral 

 spot black, and the tarsi red. The upper surface is suffused 

 with a faint metallic lustre, which is scarcely apparent except 

 upon the forehead and the narrow black margins. 



The form is moderately long, rather depressed and parallel- 

 sided. The head is entirely, closely and strongly punctured, with 

 the clypeus very short and the eyes large and prominent. The 

 pronotum is everywhere closely punctured, completely margined, 

 with the front angles sharp, the hind angles rounded away 

 and the base trisinuate. The scutellum is irregularly punctured 

 and the elytra are deeply punctate-striate, the second stria 

 breaking up in the anterior half. The pygidium is strongly 

 and rather closely punctured, the metasternum finely punc- 

 tured and thinly pubescent. The front tibia is bidentate, and 

 the middle and hind tibiae are stout and not dilated at the end. 



3 . The clypeus is very small and yellow in colour, the yellow 

 extending angularly backwards between the eyes. The club of 

 the antenna is moderately long, and the longer claw of the front 

 foot only is cleft. 



$ . The clypeus is rather larger and of a dark red colour. The 

 eyes are smaller, the terminal tooth of the front tibia long and 

 blunt, and the longer claw of the middle and hind feet minutely 

 cleft at the tip.

This species has a remarkably deceptive resemblance to A. com- 

 munis, Burin., and its immediate allies, and a close examination is 

 necessary to reveal the fact that it renlly belongs to a different 

 section of the genus. The metallic suffusion is extremely faint, 

 but its significance is confirmed by the complete absence of a 

 third tooth to the front tibia, much shorter male antennal club
