and the ‘‘Conspectus systematicus” which Schicedte prefaced to several 
large families especially studied by him, form a key to the determination 
of larvze ; but these keys are by no means alwats in a convenient form, 
e. g. in the family Scaradeide. In the Ceramlycide he gives concise 
diagnoses of the larval characters of the various sub-families, and Prof. 
Ganglbauer (Bestimmungstabellen der Europaischen Coleopteren, VII, 
Cerambycide, in Verh. K.-K. Zool.-bot. Ges. Wien, XXXI, p. 681, 
1881), has brought these diagnoses into the form of a synoptic table, 
illustrating the same with copies from some of Schicedte’s figures. Since 
both the original text of Schicedte 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 larva, we think we 
are justified in devoting some space tu a translation’ of the table given 
by Ganglbauer, the accompanying figures having been copied by Dr. 
Geo. H. Marx in outline, direct from Schicedte.
