basal insertion of the antennae in 9 's of lecontei will, of 

 course, make separation easy, but in d^'s of lecontei and espe- 

 cially mgenfilis this difference is less marked. 



In distribution as well as in degree of interspecific varia- 

 tion, ahctacea rather closely parallels hispoides. Examples are 

 known to me from New Hamphire, Lake Superior, Rocky 

 Mountain region from Alberta (Bannf) to New Mexico at 

 altitudes of 9000 to 11,000 feet in Colorado and New Mexico, 

 British Columbia (Emerald Lake); Vancouver; Oregon 

 (Portland) and California (Lake Tahoe, Kings River and 

 Santa Monica). 



M. iinbellis Lee. 



A single 9 from Sonoma County, California (Van Dyke 

 Collection), is before me. The type— a unique 9 — was 

 from Oregon. The species may be at once known by the 

 tabular characters. In the specimen at hand the third and 

 fifth elytral intervals are wider. 



M. barbicoriiis Latr. 



This European species is included on the basis of a speci- 

 men from Long Island (New York) in the Linell Collection, 

 and a small series taken on elm at Dorchester, Mass., by Mr. 

 Percy G. Bolster of Boston. The latter specimens have been 

 taken recently (June, 1909), but the Linell specimen must 

 have been found many years ago. The cf of barbicornis (I 

 have not seen the 9 ) is at once known by the dense erect 

 pile of the antennal club and two outer funicular joints, the 

 club itself very elongate — as long as the entire scape and 

 funicle. The beak is short and stout, about as long as the 

 head, dilated beyond the antennal insertion which is at about 

 the middle of its length ; thighs not toothed ; size rather 

 small. 



The species of Magdalis with toothed claws are less numer- 

 ous than those with simple claws and will not now be treated 

 at length; the following notes, however, may be of service, 

 and will probably be sufficient for their separation. Of the 

 nine species known, six occur in the eastern United States,
