ANALYTICAL TABLES. 187 



Next we go to the fii'st division under CO — , which is — 



D— Head not suddenly and strongly constricted at the base. 



We must determine first what is meant by suddenly 

 and strongly constricted at the base, and here some 

 known examples will help us greatly. Suppose we 

 decide that the head is suddenly and strongly con- 

 stricted. "We say " No, " to D — and proceed to DD — . 

 The first division under DD — is — 



E— Lateral suttu'es of the thorax distinct; base as wide as the elytra. 



If we say " No " to this, we go to — 



EE— Lateral sutures of the thorax wanting. 



The first division under this is — 



F — Tarsi perfect, with distinct claws ; eyes normal ; prothorax at the 

 base narrower than the elytra. 



An examination of F — , FF — , and FFF — shows that 

 the narrow prothorax distinguishes F — from FF — , 

 and the eyes normal, with distinct claws, distinguishes 

 F — from FFF — . Suppose we say ' ' Yes ' ' to this 

 character, we go to — 



G— Hind cox£e not prominent. 



If we decide that the hind coxae are prominent, we go 

 to GG — , the first division of which is — 



H— Claws simple; head horizontal. 



If we say "No" to this, we go to — 



HH— Claws cleft or toothed ; front of head vertical,— 



and at the end of this line we find, in parenthesis, the 

 name of the family, Meloidse, which is the family of 

 blister beetles, all of which have a very curious life 

 history. 



Half a dozen beetles traced through in this way 

 will give vis a very fair understanding of the tables. 



The names of the families all end in -idse, and the 

 accent falls on the syllable just before this termination.
