Chittcnden, F. H. "New Species of Spbenophorus," etc.. three 

 papers, in Proc. Ent. Soc. Wash., VI, 1904, 127137 ; VII, 

 1905, 5064; 166182. 



Many other articles treating of the economic phases of the 

 beetles have appeared, a list of those up to 1900 being given by 

 Forbes. (1890 and 1903.) Four of the eight genera of the sub- 

 family are represented with us. 



KEY TO EASTERN GENERA OF SUBFAMILY CALANDRINvE. 



a. Side pieces of metathorax very wide; epimera large; size very large, 



20 or more mm. I. RHYNCHOPHORUS. 



aa. Side pieces of inetathorax moderate or narrowed; smaller, not over 



17 mm. in length. 

 6. Club of antennae wedge-shaped; epimera of mesothorax broadly 



truncate on the outer side; length 5 mm. or more. 

 c. Third joint of tarsi broad, spongy beneath, the brush narrowly di- 

 vided. II. RHODOB^ENUS. 

 cc. Third joint of tarsi glabrous at middle, spongy or pilose at the 

 sides or wholly glabrous. III. SPHENOPHORUS. 

 &b. Club of antennas oval; epimera of mesothorax acute on outer side;
