DESCRIPTMOF THE EARLY STAGES OF SEVERAL NORTH AMERICAN 



COLEOPTERA. 



By H. F. WICKHAM. 



The following notes refer to the transformations of several 

 Coleoptera which have not heretofore been described in the 

 literature of the subject, and are offered as a continuation of 

 the series begun in the preceding number of the Bulletin. 

 While it is to be regretted that the works of Schiodte and 

 Perris are not accessible in order that these insects might be 

 compared with their near European relatives, I have tried to 

 make the descriptions and figures clear enough to serve, if 

 necessary, as a basis of comparison in treating of others in the 

 future. The preparatory stages of American beetles have 

 been sadly neglected, in consequence probably of the difficulty 

 of successfully carrying larvae to their full growth and 

 through their final transformations. 



Pterostichus lucublandus Say. Plate IX, Fig. 5. 



The larva of this species has been carefully described by 

 Schaupp in the Bulletin of the Brooklyn Entomological Soci- 

 ety, III, p. 88. A figure of the pupa drawn only an hour 

 before the emergence of the beetle is given herewith to com- 

 plete the history. The length is 10 mm. 



A larva found at Independence, la., on the .first of Septem- 

 ber, pupated on the sixth and the perfect insect appeared on 

 the sixteenth.
