432 TEKTIAliY INSECTS OF NORTH AMERICA. 



2. HEERIA LAPIDOSA. 

 PI. 27, Figs. 3, 19. 



In color this species entirely resembles the preceding both as to body 

 and antennae. The head and first joint of antennae are here as coarsely 

 granulate as the thorax, while the other joints of the antennae resemble 

 those of the last species ; the front of the head is as there. The thorax is 

 perhaps a trifle longer than in H. gulosa and has straighter sides, but other- 

 wise does not differ. The hemelytra are similarly punctate. The main 

 difference is to be found in the abdomen, which, though full, is not nearly 

 so full as in the preceding species, the breadth being scarcely half the 

 length of the body. 



Length of body, 8.5 mm ; antennae, 4.5 mm ; breadth at base of thorax, 

 3.25 mm ; at middle of abdomen, 4""". 



Florissant. Eleven specimens, Nos. 1648, 1884, 3767, 4617, 5703, 

 5965, 8!)4!i, 1'22-tl, 14179 and 14197, and of the Princeton Collection, 



1.804, 1.817. 



3. HEERIA FCEDA. 



In color like the other species. Head scarcely granulate, the front 

 between the antenna', advanced angularly by half the length of the first 

 antennal joint to less than a right angle, the angle rounded. Antennae 

 throughout slenderer than in the other species, and shorter, scarcely in the 

 least granulate anywhere. Thorax coarsely granulate, the base a third 

 longer than the apex, less than twice as broad as long. Hemelytra rather 

 distantly punctate. Abdomen much as in H. lapidosa. 



Length of body, 8 ram ; antennae, 3.25 mm ; breadth at base of thorax, 

 2.7 mra ; at middle of abdomen, 4 mm . 



Florissant. Three specimens, Nos. 3097, 7874, 7974. 



Subfamily CORIZIDA Mayr. 



A few fossil forms have been referred to this group, not very abundant 

 in species at the present day. The most prolific genus in either Old or 

 New World is Corizus, to which all the four species from the American 

 Tertiaries described below are referred. The only described European 

 form is one from Oeningen referred by Heer to an extinct genus, Harmos- 

 tites ; Corizus, however, is said to occur at Aix, but, as I shall point out 

 below, its reference here is doubtful.
