II YLEOIDES Smith. 

 The species of this genus almost perfectly imitate in color and 

 pattern the Tasmanian Eumenid Rhynchium mirabile Sauss. Is it 

 possible that by some accident Smith figured the mouth-parts of the 

 Rhynchium for those of the Hyleoides ? (see Trans. Amer. Ent. Soc, 

 xxix, p. 186).

A third species, A. cygni Ckll., is described in Ann. Mag. Nat. 

 Hist, Sept., 1904.
