ness of Mr. James Waterston I am able to state that the genotype 

 female in the British Museum also has this hairy ring at the base of 

 the abdomen. These hairs are fine and although close together 

 stand up straight so that when viewed from certain positions the 

 girdle might be easily overlooked as it has not the glistening white, 

 woolly, or felt-like appearance characteristic of certain genera. In 

 order that the genus may be recognized it should be transferred to 

 a different section of the Dalla Torre and Kieffer key where it will 

 stand close to Piezobria Foerster whose scutellum is emarginate 

 behind and hence only obscurely two-toothed. The posterior angles 

 of the scutellum of Dicerataspis are prolonged into distinct teeth. 

 Dicerataspis is also closely related to the neotropical genus Dissodon- 

 taspis Kieffer, described in 1909 10 , which may prove a synonym of it.
