1. LUJYIIomKlS Stal. 



This American genus, best developed in Mexico and Central America, 

 where seven species are recorded, ami which also extends into the United 

 States, where two species are known in the eastern portions, seems to be 

 represented in the Florissant shales by one species, though the obscurity 

 of the single specimen makes the reference somewhat doubtful. Xo extinct 

 forms have before been recognized.

PI. iM, Fig. ~>. 



The single specimen thai is referred here is verv poorly preserved, 

 but differs marked! v from all. other specimens; in general the aspect of the 

 insect, is that of a Ligyrocoris, and I have accordingly placed it in that 

 genus. The head appears to be of the same width as the thorax, which is 

 subquadrate, narrows verv little forward, and is rather broader than long. 

 The antenna- are slender, and if turned backward would reach about 

 half-way to the tip of the closed hemelytra. The fore and middle femora 

 are very similar in character, the middle pair slightly the longer, moder- 

 ately stout, of nearly equal width throughout, the hind femora longer still 

 and perhaps a little slenderer, reaching nearly to the tip of the abdomen. 

 Hemelytra with the membrane reaching far beyond the tip of the abdo- 

 men, the veins dnskv ; the whole body is of a uniformly dark color. 



Length of body, . r >.25 mi " ; including the closed hemelytra, 7""" : breadth 

 of body, l.G mm ; length of hind tibia- and tarsi, 4""".

2. STKNOl'A.M KKA gen. nov. (art^n?, 1'aniera, nom. gen.). 



A genus of Myodocharia in which the anterior lobe is not only several 

 limes longer than the posterior, but which bv its Initiate form is even wider 

 than it, the posterior lobe being reduced to a mere narrow belt. The whole 

 in.-ecf is of compart oval form, less than three times longer than broad. In 

 the last respect it reminds one of Trapexns. but in its principal features it 

 -i-i-ins to be most ne.irK allied to I'amera. The antenna- are scarcely longer 

 ilia'i the extreme width of the bodv and >carcely have the apical joint
