HEMIPTERA— HETEROPTERA-COREIDiE. 431 



especially the third, enlarging apically where truncate ; last joint long oval, 

 scarcely moie than one-third as long as the third, nearly or quite as stout 

 as the basal. Thorax trapezoidal, the apical margin of the breadth of the 

 head, the basal fully half as broad again, the sides more or less rounded. 

 Hemelytra large, covering the abdomen, except possibly the sides in the 

 broadest species, the corium reaching the middle of the apical half of the 

 abdomen. All the species have heavily granulate thorax, the last joint of 

 the antennaj more or less granulate, and the corium of hemelytra coarsely 

 punctate. 



The genus is named in memory of Oswald Heer, of Switzerland, the 

 principal student of fossil msects in the last generation. 



Three species are known, all from Florissant. 



TaMe of the species of Heeria. 



Head broadly rounded between the antenna. 



Body ample, much less than twice as long as broad 1. H. gulosa. 



Body less ample, twice as long as broad 'i. H. Japidosa.

PI. 27, Figs. 5, 12, 18 ; PL 28, Fig. 17. 



Whole body tolerably uniform blackish fuscous, the lateral incisures 

 of the abdomen paler. Head, whole of first, apical extremity of second and 

 third, and basal two-thirds of fourth joint of antennae finely granulate, these 

 parts in the antennse blackish, the other parts of the middle joints of the 

 antennas pale testaceous and faintly granulate, the apical third of the fourth 

 joint smooth and blackish fuliginous ; front of head between the antenna} 

 broadly rounded, scarcely advanced, not at all angulate. Thorax heavily 

 granulate, almost twice as broad on the basal as on the apical margin, 

 and fully twice as broad as long. Hemelytra with the corium heavily and 

 irregularly punctate. Abdomen broad and full, about half as broad again 

 as the base of the thorax. 



Length of body, 9.15"""' ; antennse, 4.8"™ ; breadth of base of thorax, 

 S.SS"" ; middle of abdomen, 5™"".
