240 FAMILY VI. — COREIDjE. 



When fresh and not weather-beaten it is thickly powdered 

 beneath with a white mealy substance. Occasionally it occurs 

 upon goldenrod, in the pollen and flowers of which it deeply 

 buries itself so as to be almost out of sight." Ashmead (1895, 

 320) found it common near Utica, Miss., in the cotton fields 

 where it was feeding on the juices of the plant. He describes 

 the egg as triquetrous, of a golden-bronze color with fine 

 hexagonal reticulations and 1 mm. in length. This is the only 

 mention found of its being injurious to plant life. In the sand 

 regions of northwestern Illinois Hart found it frequently in 

 August on the flowering spurge, Euphorbia corollata L. It and 

 Chondrocera laticornis Lap. are the only ones of our eastern Het- 

 eroptera having one or more of the antennal joints widely 

 dilated. 



Tribe VII. CHELINIDINI tribus nov. 



Oblong-oval species of medium size having the head sub- 

 cylindrical, porrect, three-fourths or more the length of prono- 

 tum, narrowed and produced forward in front of bases of an- 

 tennae, not calloused behind the eyes; cheeks porrect, shorter 

 than tylus, their tips subconical or subacute, tylus strongly 

 deflexed between them; antenniferous tubercles small, widely 

 separated ; antennae stout, reaching apex of scutellum, basal 

 joint swollen, curved, subclavate, half the length of head, 

 2 and 3 triquetrous, subequal, fourth shortest, fusiform ; beak 

 reaching or surpassing hind coxae; femora all armed beneath 

 on apical half ; tibiae simple, three-sided ; spiracles equally 

 distant from the apical and front and hind margins of the 

 ventrals. 



Stal (1870, 180), followed by Van Duzee in his Catalogue, 

 has placed the genus Chelinidea Uhler under the tribe Coreini, 

 but it does not run there by Stal's key in his Bidrag, and the 

 elongated head, porrect cheeks, armed femora and triquetrous 

 second and third antennal joints and tibiae preclude its belong- 

 ing there. I have therefore founded for it a new tribe. 



I. Chelinidea Uhler, 1863a, 365. 



In addition to the tribal characters above set forth, the 

 species of this genus have the ocelli separated by a space 

 greater than that between them and the eyes ; bucculae about 

 one-third the length of basal joint of beak, their margin
