AMERICAN COLEOPTERA. 365 



CERATOJIEGILLA, g. n. 



Shape and form of Hippodamia, claws dentate at base, coxal lines 

 obsolete, thorax sinuate and margined at base; antennge with the 

 third joint longer than the second, broadly dilated at apex, with the 

 inner apical angle ciliate. 



The structure of the antennae is unique in the family. 



C Ulkei, sp. n.— Oval, sub-opaque, antennas, tarsi and palpi ochreous ; 

 head with a white spot in front of each eye, thorax with the sides bordered 

 with ochreous, anterior angles broadly ochreous, and a very minute line in the 

 middle of the anterior margin also ochreous ; elytra rather closely punctate, a 

 triangular spot on the base, the external margin irregularly, and an elongate 

 common sutural spot near the apex fulvous. L. -22 inch. 



Hudson's Bay. (Ulke.) Probably the markings are suffused. 



ERIOPIS, Muls. (Type connexa.) 



Meso-coxal line absent, claws bifid, thorax quadrangular, base sinu- 

 ate, margined at the angles but not in front of the scutellum. 



E. connexa, (Germ.) Ins. Sp. Nov., p. 621, S39.— Oblong, black, extremely 

 finely and obsoletely, head more visibly, punctate; thorax with the sides, and 

 a spot on the front and hind margins yellow; elytra with the margin, base 

 and two dorsal spots yellow; the marginal line is dilated in five places, one 

 basal, one sub-humeral, one medial, one at three-fourths and one sub-apical. 

 L. -22 inch. 



Texas, California (Mulsaut) Vancouver (British Museum). This 

 species is spread throughout South America, but its occurrence in 

 the United States is exceptional. 



HIPPODAMIA, (Chev.) Dej. Cat. (Type 13 -punctata.) 

 Thorax sub-transverse, not margined at the base, claws bifid, pos- 

 terior tibial spurs distinct, meso-coxal none, meta-coxal irregular and 

 obsolete. 



The species of this genus are very variable and difficult to define 

 satisfactorily. Two occur in North Europe, one of which is also 

 found in North America and extends down to the West Indies.
