270 PROCEEDINGS OP THE AMERICAN ACADEMY. 



outer margin straight, inner margin roundly dilated near the base ; tenent 

 hairs two or three, clavate. Coloration rather variable ; dorsum marked 

 anteriorly with transverse rows of pale yellow circular spots (Fig. 37) ; 

 sides of abdomen with many regular rows of minute, circular, yellow 

 spots ; sternum posteriorly yellow ; body well clothed with bristles, 

 which are short and reclinate, except upon the posterior segments, where 

 they become longer and more numerous. Furcula long and stout ; 

 dentes scarcely tapering; mucrones (Fig. 40) almost one third as long 

 as the dentes, oblong-lanceolate, with rounded apex. Length, 1.2 mm. 



Two specimens with no locality given. 



The Japanese examples agree satisfactorily with North American 

 representatives of S. hortensis ; in fact, I found some of our specimens 

 which match them quite closely in coloration. A study of Packard's 

 types leaves no doubt that quadrisignatus Pack, is a synonym of hor- 

 tensis Fitch. Professor Harvey kindly sent me numerous specimens of 

 his albamaculata, which also prove to be hortensis ; he regards the last 

 antenna! segment as being composed of nine subsegments, evidently 

 considering the last subsegment as three. The identity of the European 

 pruinosus Tull. with the American hortensis was called to my attention 

 by Dr. Shaffer, to whom I had sent examples of our species, and he has 

 since sent me ten South American specimens of the same form. 



S. hortensis has been found in various parts of Europe : in Sweden 

 (Tullberg), Finland (Renter), Russia (Scherbakow), and Bohemia (Uzel). 

 In the United States it is recorded from New York (Fitch), Maine 

 (Packard, Harvey), Massachusetts (Harris), and Ohio (MacGillivray). 

 Finally, it is reported from subantarctic America (Schaffer).
