DERODONTID^. 



40(). Peltastica tuberculata Mann., var. Reitteri Lewis. — A species of this 

 genus has been described by Mr. George Lewis, from Japan, of which 

 Dr. Horn writes: "Having compared specimens sent me by Mr. Lewis 

 with the series in my cabinet of our species, they seem scarcely more 

 than a variety." Oregon to Alaska. 

 Mr. Lewis states that Reitteri diffars from tuberculata in several characters 

 which he specifies, but in view of the comparisons made by Dr. Horn 

 these do not seem of sufficient value to remove it beyond a variety. 

 Ent. Month. Mag. xxv, 432.

 having remained united for many years and still separable by few ex- 

 cept the practiced systemacist, the records of distribution in our litera-

 Combined it is northward from Pennsylvania to Hudson Bay and west- 

 ward to Manitoba. Europe, eastern and western Siberia. P. vii. 115;

 species in Europe and Asia. The e::aniple taken on the American coast, 

 according to Sahlberg, belonged to var. dianae; var. kamtschaticus Mots., 

 occurs in Kamtschatka, Dauria and Japan, and is considered by the 

 describer as possibly a geographical variety of dianse. Mr. Geo. Lewis 

 contends that it is a valid species. Eut. Mouth. Mag. 1889.
