66 AMERICAN ENTOMOLOGY. 



Desc. Head black, with a yellowish, spot at eacli superior can- 

 thus of the eyes, and another at the mouth : antennae at base 

 yellowish : front with an impressed line : thorax densely punc- 

 tured ; anterior and lateral margins yellow, tinged with rufous : 

 a yellow abbreviated Hne commences at the middle of the ante- 

 rior margin, and terminates at the middle of the disk; two dis- 

 tant yellow abbreviated lines arise from the basal margin, and 

 terminate each side of the middle of the disk : scutel black : 

 elytra yellow, with striae of impressed punctures : two dilated 

 black vittse, of which one originates on the humerus, and does 

 not reach the tip, the other is rather shorter, originating midway 

 between the preceding and the scutel, and hardly approaching 

 the suture at its tip ; suture black : anal segment whitish ; be- 

 neath black : feet rufous.

 the figure were taken, on the bank of the Mississippi river, above 

 the confluence of the Ohio. Some doubts may reasonably be 

 entertained, respecting the identity of this insect and the viduatus 

 of Fabricius, on account of its smaller size, and the character of

 But as the present specimen corresponds with his description in 

 every other respect, and as the difference in magnitude may be 

 dependent on sex alone, I have ventured to refer it to that spe- 

 cies. It is now figured for the first time. 



["Different from the Fabrician species according to Suffrian, 

 who (Linn. Ent. 7, 227) has named it Pachybraehys Htigiosus.

Cryptocephalus othontjs. — Specific character. Black ■ 

 thorax with a narrow margin and abbreviated line, dull fulvous ; 

 elytra yellowish, with two black vittse. 



Desc. Head with small dense punctures ; black, with two trian- 

 gular yellow or rufous spots at the superior canthi of the eyes : 

 antennae yellowish at base : thorax black, confidently punctured, 

 with a narrow margin all round, and a dorsal line extending from 

 the anterior edge to the middle, dull fulvous : scutel black : elytra 

 dull yellowish-white, with two broad black vittae abbreviated 

 near the tip, the exterior one originates at the humerus, and the 

 other takes its rise on the basal margin, midway between the ex-
