THE FAMILY LYCTID^E. 135 



with characters mentioned by Mr. Kraiis. It is probable that 

 there is some overlapping of the ranges of these two allied species 

 in Florida and from Texas to California, and that in such localities 

 occasional specimens will be found which occupy an intermediate 

 position. 



L. parvulus Casey. — Arizona, California, and Utah. This evi- 

 dently indicates the natural distribution of the species. 



Division II. 



SUBDIVISION D. 



L. linearis (Goeze). — This species is recorded in literature as extend- 

 ing over Europe, and especially England, France, and Germany, 

 where it lives in natural growth, cordwood, etc. This evidently rep- 

 resents its natural habitat, from which it has been introduced in 

 commercial wood products to many other countries of the world, 

 but it would appear from observations and records in the United 

 States that it becomes permanently established only in those coun- 

 tries with climates similar to that of central and northern Europe. 

 The species appears to be permanently established in the States 

 north of North Carolina, Tennessee, and Arkansas. There are a 

 great many records from this area, including Maine, Massachusetts, 

 New York, Pennsylvania, Virginia, West Virginia, Ohio, Indiana, 

 Michigan, Illinois, Missouri, Iowa, and Minnesota. The specimens 

 in the national collection show but a single record from the South 

 Atlantic and Gulf States, and that is evidently a temporary intro- 

 duction. Undoubtedly the species is frequently carried into the 

 southern region, but evidently does not survive there. 



THE GENUS LYCTOXYLON. 



L. ja/ponum Reitter. — Japan, China, and India. This probably 

 represents the natural range of the species, from which it has been 

 introduced into Europe, America, and other countries, possibly 

 becoming established in those with climatic conditions similar to 

 that of its original habitat. The recorded intioductions into the 

 United States are from China into California and Massachusetts, and 

 probably from Japan into New Jersey. 



THE GENUS MINTHEA. 



M.. rugicollis (Walker) . — Philippine Islands, Siam, China, Ceylon, 

 and the Malay Archipelago. This probably represents the natural 

 habitat, from which it may have been introduced into Europe, the 

 West Indies, and the Hawaiian Islands. 



M. stichothrix (Reitter). — Bogota, Colombia, South America.
