98 THE GENUS CORYTHUCHA 



Nervures all yellow to light brown. Nearly obsolete brown spots on par- 

 anota. Brown band across base of elytra, but with no distinct band across 

 apical portion of elytra, nervures may be embrowned but areoles not clouded. 



Type and para types iii the Drake collection examined. They 

 were collected on Ulmus americana at Pliimmer's Island, Mary- 

 land, by Mr. W. L. McAtee. Other specimens from New York 

 and South Carolina were examined. Osborn and Drake also 

 report its capture at Lisbon, Ohio. Although resembling pallida 

 Osborn and Drake in general color markings, it may be distin- 

 guished from pallida by the smaller size and having a brown band 

 across base of elj'tra. Since Osborn and Drake first published a 

 note on pallida var. idmi, they also have come to the conclusion 

 that it should be raised to specific rank. 



43. Corythucha mail new species 



Resembling iihni Osborn and Drake. Pronotal hood only shghtly higher 

 than median carina and about equal to it in length. Height of hood one-half 

 its own length. Reticulations of hood large, abruptly constricted at the mid- 

 dle. Median carina well arched. Lateral carinae of normal height, with two or 

 three areoles. Lateral margins of elytra nearly straight. Elevations of elytra 

 large. Spines on membranous margins normal. Size, 3.7 mm. long, 2.3 mm. 

 wide. 



Nervures of hood somewhat embrowned, not dark. Paranota with a faint 

 brown spot. Elytra with a distinct basal band, but without a distinct apical 

 one, although the nervures in apical portion may be shghtly embrowned and 

 one or two areoles shghtly clouded. 



Type. — 9, Lakehurst, New Jersey. (Collection of H. G. 

 Barber.) Allotype. — cf same data as type. Paratypes. — Two- 

 females and one male, same data as type. 



44. Corythucha drakei new species 



Pronotal hood slightly higher than median carina and slightly shorter. 

 Height of hood equals one-half its own length. Median carina of normal 

 height. Lateral carina long, terminating a short distance from base of hood. 

 Reticulations of hood about same size as those of paranota. Spines on mem- 

 branous margins and nervures small and scarce. Costal margins of elytra 

 nearly straight. Tumid elevations of elytra well rounded and rather long. 

 Size, 3.6 mm. long, L9 mm. wide. 



General aspect above light brown. Nervures more or less yellowish to light 

 brown. Only a faint basal band across elj-tra. Apical band more distinct. 

 Tumid elevations more or less embrowned. 



Type. — 9 , Portland, Oregon. (Collection of C. J. Drake.)
