The Genus Scaphoideus.

scattered white bristles, sometimes embrowned ; coxae and 

 pleural pieces sometimes with fuscous spots. 



Females of this species are in hand from Ames, Iowa, 

 taken July 30, 1896, " Onaga Kans," received from Mr. E. D. 

 Ball. " Albion, N. Y., August 27, 1898," from Mr. VanDuzee; 

 Columbus, Ohio, October 10, 1898; and West Point, Neb. 

 (Bruner). 



Uhler does not describe the male, but specimens which 

 seem to belong here, and one of which has been so placed by 

 Mr. VanDuzee, may be characterized in this connection. 



d\ Length to tip of elytra 4 mm. Very light, apparently 

 immature ; vertex borders tinged with fulvous ; valve short ; 

 plates elongate, nearly as long as pygofers; outer margins 

 subangulate, sides somewhat reflexed near base, with long 

 white cilia on margin, and a bunch of black hairs beyond 

 their tip on pygofers. 



One specimen, Agricultural College, Michigan, having date 

 August 3, 1892, kindly loaned me by Prof. Pettit, and four 

 specimens from Ames, Iowa, bearing dates in July and 

 August of 1896 and 1897, collected by Mr. E. D. Ball. These 

 specimens have a peculiarly immature look, but agree so 

 exactly that they can hardly be considered as such. Their 

 very small size, as compared with 9 intricatus, raises the 

 question whether they are actually males of this species, but 

 the color and markings agree better here than with any other 

 species and the specimens mentioned by Van Duzee from the 

 Agricultural College, Michigan, may have been taken 

 together. 



According to Uhler, intricatus occurs on Crataegus bushes 

 from early August to late October in Maryland, Virginia, and 

 New Jersey.
