took place in 4 days and 12 to 13 days were passed in the pupal 

 stage. The adults in a few days emerged from their cavities and came 

 on the surface in search of food.

 to be a distinct species. C. auropunctatum is recorded as found in Austria, Germany, and France, 

 but everywhere rare.

CALOSOMA CANCELLATUM Esch. 



[PI. XVII, C] 

 (Syn.: Calosoma aenescens Lee.) 



ORIGINAL DESCRIPTION. 



[Translation.] 



Thorax very short, rough, bronze, posterior angles produced, elytra greenish- 

 bronze, obsoletely striate. Crossed with irregular short wrinkles with three series of 

 elevated oblong punctures, tibiae straight. 



From California near San Francisco. 



Length 9 lines. Head and prothorax colored very green, thickly punctate; pro- 

 thorax very short, twice as broad as long, broader anteriorly than posteriorly ; indented 

 in front in the middle, straight posteriorly; the broad, blunt hind corners project out 

 prominently, lateral margins broadly turned up, shield black. Elytra not much 

 broader than prothorax, long, indistinctly striate, all the spaces between are uneven 

 because of cross lines; broad intermediate spaces have larger grooves, whereby three 

 rows of long chainlike granules are formed. On elytra all depressions colored light 

 metallic green, all elevations very green. Ventral side of body has on the sides of 

 prothorax and breast green glimmerings; all the rest as well as the legs are black. 

 Middle tibise of female straight. 



This species was described by Dr. Friedrich Eschscholtz in 1829, 

 who recorded its habitat as California near San Francisco. It has 

 later been taken in Arizona, California, Idaho, Indian Territory, Mon- 

 tana, Nevada, Oregon, Utah, and Washington. Dr. LeConte in 1854 

 described a new species (Calosoma aenescens) as occurring at Fort 

 Vancouver. The writers have had the opportunity of studying the 

 type which is deposited in the Museum of Comparative Zoology, 

 Cambridge, Mass., and find it does not differ from C. cancellatum~EsGh.. t 

 and it is, therefore, considered as a synonym of that species.
