THE FAMILY LYCTIDiE. 133 



and Australia, from about the fifty-fifth parallel north to the fortieth 

 parallel south. The genus Lyctus has practically the same range as 

 the family; the genus Lyctoxylon seems to have its natural distribution 

 in eastern India and Asia between the twentieth and fortieth paral- 

 lels north; while in the genus Minthea one species is from Rodriguez 

 Island and the Philippines, with a record from southern Europe, and 

 the other species is from Bogota, Colombia, South America. 



It appears that the center of distribution of the greatest number 

 of species of the family is between the twentieth and fortieth parallels 

 north in both continents. 



The available evidence would indicate that the natural distri- 

 butions of the species studied by the writer are approximately as 

 follows:

Section al. 



• L. impressus ComoUi. — Northern Africa, southern Italy, Greece, 

 Spain, and the Caucasus. Probably temporarily introduced into 

 central Europe and southern North America.

L. californicus Case}^. — Lower California. 

 L. prseustus Erichson. — Peru and BraziL 



Series c2. 



L. paraUelopipedus (Melsheimer). — Florida, Texas, Louisiana, Geor- 

 gia, South Carolina, Virginia, West Virginia, District of Columbia, 

 Long Island, N. Y., Ohio, and Missouri. The natural distribution 

 of the species is evidently in the South Atlantic and Gulf States, and 

 in part of the Mississippi and Ohio valleys, from which it has been tem- 

 j)orarily introduced into other States. 



L. curtulus Casey. — California, Arizona, Texas, and Guatemala. 

 This evidently represents its natural distribution. One record from 

 Montana indicates temporary introduction, and a record from the 

 Sandwich Islands may represent a permanent introduction.
