DISTRIBUTION OF COLKOPTERA. 129 



Obs. — D. murinus Lin. frequently iippears in our literature, per- 

 haps from a wrong determination of certain forms of caninus Germ, 

 with brown antennte and a minimum of fulvous mottling. 



279. Attagenus piceus OUv., megatoma, Fab. dichrous, rufipennis, spnrcns, Lee. 

 The synonymy indicates local variableness. It is found abundantly 



in houses and granaries, also frequenting tiowers. It occurs nearly 

 everywhere from the Atlantic to the Pacific, and also is general in 

 Europe, whence it has undoubtedly been imported. P. vii, 109 ; P. 

 Am. P. XX, 355 ; Lintner's second Annual Report, New York, p. 

 46, gives its oeconomic history. 



280. A. pellio Linn., bipunctatus DeG. 



This species, introduced from Europe, is much rarer, living mostly 

 on desicated animal substances ; it is occasional in museums. It has 

 occurred in Nova Scotia, Canada, Michigan, New York and various 

 places in the eastern States. P. vii, 109 ; P. Am. P. xx, 356. 



281. Anthrenus scrophularise Linn., var. thoracicus Mels., var. flavipes, var. 

 lepidus Lee 



The varieties denote color ornamentation rather than differences 

 of structure. The larvae of this beetle are sometimes very destruc- 

 tive to carpets, and occasionally infest museums of natural history. 

 It occurs in many places from the Atlantic to the Pacific, but not 

 everywhere. Europe. P. vii, 112; P. Am. P. xx, 369; Amer. 

 Nat. xii, 536. 



282. A. varius Fah., verbasci Linn., tricolor Herhst, var. destructor Mels. 



This insect is in bad repute with all who make zoological collec- 

 tions. It appears to be cosmopolite. P. vii, 112 ; P. Am. P. xx, 370 ; 

 Can. Ent. xv, 82 and 90. Heyden, 99. 



283. A. museorum Linn., castanex Mels., verbasci Fah. 



This species is very abundant from early spring to June on various 

 fiowers, especially spiraea, codius and cadanea. It is not known 

 here to have any bad habits like the foreign species. It occurs in 

 Canada, and in nearly all the States eastward from the Mississippi. 

 Europe. The southern parts of east and west Siberia. P. vii, 112 ; 

 P. Am. P. XX, 370 ; Can. Ent. xv, 90. Heyden, 99. 



284. A. claviger Er., fuscus Lafr. 



This European species occurs in Pennsylvania, though I have not 

 met with it. T. v, 252 ; P. Am. P. xx, 371.
