and the "Conspectus systematicus" which Schioecite prefaced to several 

 large families especially studied by him, form a key to the determination 

 of larvK ; but these keys are by no means al\va\s in a convenient form, 

 e. g. in the fami'y ScarabteidcB. In the Cera?}ibycidcs he gives concise 

 diagnoses of the larval characters of the various sub-families, and Prof. 

 Ganglbauer (Bestimmungstabellen der Euroi)aischen Coleopteren, VII, 

 Cerambycidas, m Verh. K.-K. Zool.-bot. Ges. Wien, XXXI, p. 68 1, 

 i88i), has brought these diagnoses into the form of a synoptic table, 

 illustrating the same with copies from some of Schioedte's figures. Since 

 both the original text of Schioedie and Ganglbauer's paper are not gen- 

 erally known in this country and certainly have not been used by those 

 who have described North American Cerambycid larvis, we think we 

 are justified m devoting some space to a translation of i he table given 

 by Ganglbauer, the accompanying figures having been copied by Dr. 

 Geo. H, Mar.x in outline, direct from Schioedte.
