TRIBK X. MAGDALIXI. 257 



Described from Lake Tahoe, Cal. Fall records it with doubt 

 from Paris and Kineo, Maine; Fitzwilliam and Mt. Washington, 

 New Hampshire. Occurs on spruce. A specimen from Newfound- 

 land in the Leng collection is also doubtfully referred to this 

 species. 



375 (8627). MAGDALIS ALUTACEA Lee., Bull. IT. S. Geol. & Geog. Surv., IV, 

 1878, 463. 



Black, opaque, alutaceous. Beak of male stout, alutaceous, slightly 

 wider beyond the base of antennae which is at apical third; of female more 

 slender, less dull, antennae inserted at middle. Head rather sparsely 

 punctate. Eyes of male separated by only one-half, of female by three- 

 fourths, the width of the beak. Thorax slightly longer than wide, hind 

 angles acute, divergent, surface densely, not coarsely punctate. Elytral 

 intervals rather wide, flat, the stria? not impressed. Length 4.2 mm. 



Southport, Maine, July, August. Occurs in high altitudes 

 from New Hampshire, Lake Superior, Banff, Alberta and Van- 

 couver to New Mexico; probably boring in the terminal twigs of 

 pine. "Differs from gent His by the divergent hind angles of 

 thorax, less convex and less deeply striate elytra, with wider in- 

 tervals which are not rugose but alutaceous." (LcContc.) 



376 (- -). MAGDALIS BARBICOKNIS Latr., 1804, 103. 



Black, subopaque; antennae and tarsi reddish-brown. Club of male very 

 long, fuscous; of female shorter, ovate. Beak short, stout, only as long as 

 head, dilated beyond the antennal insertion, which is about at middle. 

 Thorax as long as wide, sides rounded in front, disc somewhat flattened, 

 coarsely punctate, that of female with three foveae. Elytra deeply 

 striate-punctate, intervals convex, very finely strigose. Femora not toothed. 

 Length 3.5 4 mm. 



West Point, N. Y., June 1. A European species taken on Long 

 and Staten Islands, N. Y., and on elm in June at Dorchester, Mass. 

 The male is easily known by the antennal club, which is as long 

 as the entire scape and funicle, and hairy. In the two females 

 at hand the thorax bears two or three blunt teeth each side in 

 front of middle, thus forming a connecting link with the next 

 group. 



GROUP II. 



Nine species of Magdalis having the claws toothed are known 

 from the United States, six of which occur in our territory. In 

 none of them does the scape of antenna' completely pass the eyes 

 as stated by Horn. All have the femora toothed. 



KEY TO EASTERN SPECIES OF GROUP II. 



a. Mesosternum with an elongate tubercle between the middle coxa?; 

 head elongate-conical; length 4 6 mm.
