 the third joint distinctly dilated in the male.

233 (10,841). HYPERODES MIRABILIS Dietz, 1889, 49. 



Oblong, rather stout. Piceous, variegated above, especially on sides 

 and declivity of elytra, with white and pale brown scales: scutellum and 

 humeri covered with cream-colored scales; antenna? and legs reddish- 

 brown; pubescence yellowish with a brassy lustre. Beak stout, about as 

 long as thorax, wider at base than apex, carinse feeble. Thorax at base 

 as long as wide, base distinctly wider than apex, sides broadly rounded: 

 disc feebly constricted behind apex, densely punctate, the median carina 

 very fine. Elytra at base more than one-half wider than thorax, sides 

 parallel for three-fourths their length; strial punctures large, close-set; 

 intervals wide, flat, the alternate ones with a row of rather distant. 

 clavate seise. Length 4.5 mm. 



Described by Dietz from a single Illinois specimen, now in the 

 Flke collection at Pittsburg. 



234 (8466). HYPERODES HUMILIS Gyll., Schon., 1834, 284. 



Oblong. Piceous-black, subopaque; thorax with a stripe each side, 

 extending onto the humeri, and a small spot in front of scutellum covered 

 with large pale scales; sides of elytra sparsely covered with similar 

 scales; antennse, tibiae, tarsi and apex of thorax, dark reddish-brown: 

 pubescence fine, reddish or grayish-white. Beak almost as long as thorax, 

 tricarinate, densely punctate, the median carina stronger. Thorax one- 

 fhircl wider than long, sides feebly rounded, disc densely and finely 

 rugose-punctate and with a faint narrow abbreviated median carina. 

 Elytra one-half wider at base than thorax, sides as in mirabilis: disc 

 feebly and broadly impressed at basal third, strial punctures large; in- 

 tervals flat, the alternate ones with a row of short, pale, suberect sette. 

 Last ventral of female with a large, subquaclrate, shallow fovea. Length 

 4 4.5 mm.
