This "notice" is in fact a nionograpli of the genus; on the whole, the most reliable and 

 satisfactory one we have. The author's well-known extreme conservatism perhaps never ap- 

 peared to better advantage than in this case, of a genus of which the rather niunerous species 

 are colored so uniformly, and at the same time present so much variation in size and shape. 

 Numberless nominal species are here laid, and the residuum may be considered a safe basis 

 for further study of the genus ; for it is extremely imliliely that there are feiver good species 

 than this author allows. Two, G. advena and C. senex, are figured in colors ; while of most of 

 the rest, the heads are shown of life size on the black "quadruple plate" (really two double 

 plates, 1 and 1&). Here is the list of them aU, with the references both to the pages and to the 

 plates, as the publication is not in every library : —
