370 TERTIARY INSECTS OF NORTH AMERICA. 



distant spines. Abdomen ovate, constricted at the base, rather broadly 

 rounded, and not produced apically. 

 A single species is known. 



APOREMA PRJESTRICTUM. 

 PI. 20, Fig. 4. 



The body is of a dark and tolerably uniform color. The surfaces of 

 the thorax and scutellum are smooth, but the edges of the latter transversely 

 wrinkled. The hemelytra are light colored or pallid, with more or less 

 infumated costal edge, which expands into an infumated spot at the tip of the 

 curium and of the cuneus, in the former case large, in the latter small; the 

 inner margin is scarcely infumated and the membrane clear. Legs blackish. 



Length, 6.5 ram ; breadth of thorax, 2.65 mm ; abdomen, 2.85 nim ; length 

 of hind tibiae, 2.5 mm . 



Florissant. One specimen, No. 9900. 



HADRONEMA Uhler. 



This genus so far as known is represented by a single species, found 

 in the Rocky Mountain region and in Mexico. The larger species here 

 added to it appears to agree better with it than with any other with which 

 T have been able to compare it, though it is doubtful whether it really 

 belongs here. 



HADRONEMA CINERESCENS. 

 PI. 24, Fig. 12. 



Head small and rounded, scarcely at all advanced in front of the eyes, 

 uniformly scabrous ; first joint of antenna? moderately stout, not more than 

 half as long as the head, the second slender, slightly incrassated in the 

 apical half or less, less than three times as long as the first joint, the third 

 about two-thirds as long as the second. Thorax scabrous like the head, 

 truncate at each extremity, less than twice as broad at base as at apex, the 

 oblique sides gently arcuate, the color of the head and thorax uniform black. 

 Hemelytra not well preserved, the legs moderately slender, stouter and 

 shorter than in the modern H. militaris Uhl. 



Length, fi.fi 1 "" 1 ; breadth, 2 mm . 



Florissant. Two specimens, Nos. 2980, 13559.
