180 AMERICAN HYMENOPTERA. 



The coloring of the male and the worker is the same, but less bright 

 and the pubescence is longer in the male than in the other sexes." 



'' Hab. North America ; Hudson Bay ; Arctic America." 

 This species may have been ternarius, sylvicola, or even 



possibly melanopygus. 



Col. C. T. Bingham failed to locate Smith's type specimen 



of this species for me. 



Boiiibiis (?) parviilus F.

Illiger, Magaz. f. Insectenk., V, 1806, p. 172. 

 Dalla Torre, Cat. Hym., X, 1896, p. 539. 

 Franklin, Ent. News, XVIII, 1907, p. 92. 



The original description is as follows : 



"Of the general size of this genus, but small. Head with black 

 antennae. Thorax hairy, sometimes cinereous, sometimes ferruginous. 

 Abdomen naked, dark and shining. Feet ferruginous. Hab. South 

 America." 



This description makes me believe that this species be- 

 longs to Xylocapa. Is the type still extant ?

 " praticolus Dalla Torre, Cat. Hym., X, 1896, p. 541. 



The original description is as follows : 



"9. Body black, clothed above with yellowish hair. Head with 

 a tuft of yellowish hairs below the antennae, and on the vertex ; thorax 

 black between the wings, which are embrowned ; legs with yellow 

 hairs at the base ; anterior half of the abdomen yellow, posterior fer- 

 ruginous. Length of body 7 lines. Taken in Lat. 65*^." 



From this description it seems most probable that the spe- 

 cies was either flavifrons or pleuralis.
