I have carefully examined the types of A. siniillima, pulchella, 

 and spinosa, all in the British Museum, and compared them with 

 the type of atripes, also the type of A. huddlia. Cam., in Mr. Eoth- 

 ney's collection. A. longiventris, Sauss., I have not seen, but the 

 description exactly corresponds with that of A. pukliella, Sniith = 

 atripes S •

$ . Very closely allied and similar to A. atripes. Smith, of which 

 this may only be an extreme form. According to the description it 

 differs in sculpture of the metanotum, which is " postice oblique 

 in V-formam elevato-strigato," and in the colour of the antennae, 

 which have the basal segments of the flagellum red.
