depression at post, end of Dors, of Abd. and without the trans- 

 verse ridges on the marginal band of Dors, and the hairs on the same

*) According to the synonyma enumerated above by the author and in 

 accordance with the ,.Regeln fur die wissensch. Benennung der Thiere" the 

 name of this species is: H. palliata (C.L.Koch). The Editors. 



See my note p. 7. The Author. 



**) The well-known name of this species generally employed is H. picea. Koch's 

 Nothrus piceus and his N. convexus, are the same species (synonyms). Koch's work 

 was published in fasciculi of loose sheets (one to a species) without any arrangement 

 creatures of different families and orders being frequently mixed in the same fasciculus ; 

 they were intended to be arranged subsequently; but a number, to render reference 

 convenient, was put on each sheet; N. picea and N. convexa were in the same fasciculus 

 but the latter had the distinctive number 1. the former. 2. Under these circumstances 

 I should not have considered it necessary to disturb the well-known name of n picea" 

 but the Editors hold that n convexa" has the priority. A.D.Michael.
