Allotype. — cf, same data as type. Paratypes. — Two females 

 and four males, same data as type. 



The above mentioned specimens were captured from apple 

 trees. Two other specimens from San Diego, California, with 

 E. P. VanDuzee collector label attached, and four specimens 

 from La Fayette, Oregon, have been examined. 



Named in honor of Mr. Carl J. Drake, who has manifested a 

 considerable interest in this genus. 



45. Corythucha spinosa Duges 



1.S89. Tingis spinosa Duges, La Nat., (2), i, p. 207. 



1901. Corythucha spinosa Chami)ion, Biol. Cent.-Amer., ii, p. 8. 



Pronotal hood slightly higher than median carina, but its height is less than 

 one-half the length of the hood. Hood extremely low and flattened posteriorly 

 from the crest, constricted at the middle, globose portion appearing slightly 

 wider than long. Reticulations of hood and paranota of same size. Median 

 carina longer than length of hood, very low, as low or lower than lateral carinae. 

 Lateral carinae of medium height, rounding and terminating a considerable 

 distance from base of hood. Costal margins of elj'tra slightly indented at the 

 middle. Spines on borders of membranous portions long and stout. Spines 

 on nervures shorter, numerous on anterior i)ortion of hood. Length 3.8 mm., 

 width 2.3 mm. 



General aspect yellow. Nervures yellow, slight brown markings on hood 

 behind crest, two slight brown spots on paranota, irregular faint brown band 

 across elytra near base and another near apex. Center of costal margin of 

 elj-tra with small brown spot. 



Food plant unknown. Has been recorded from Mexico and 

 Central America. 



46. Corythucha eriodictyonae Osborn and Drake 



1917. Corythucha eriodictyonae Os})orn and Drake, Ohio Jr. Sci., no. 8, p. 302. 



Pronotal hood slightly higher than median carina. Length of hood shorter 

 t ban median carina and height of hood aljout equal or, if any, slightly less than 

 one-half its own length. Median carina long and low, with but one row of 

 areoles. Lateral carinae high but short. Reticulations of hood the same size 

 as those of paranota. Costal margins of elytra straight. Spines on membran- 

 ous margins and nervures long, numerous and stout. Hood abruptly con- 

 stricted. Size, 3.7 mm. long, 2.2 mm. wide. 



General color above yellow or light l)rown. Nervures all yellow, a few at 

 base and near apex of elj-tra distinctly eml)rowncd. No areoles clouded. 

 General color much reseml)les that of pulliila Osborn and Drake. This species 

 very closely resembles spinosa Dugfis, and with a larger series at hand may 

 prove to be a synonym of that species. The specimens examined are slightly 



TRANS. AM. ENT. SOC, XLIV.
