1. LIGYROCORIS Stftl. 



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

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

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

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

 of the single specimen makes the reference somewhat doubtful. No extinct 

 forms have before ])een recognized.

 PI. 24, Fig. 5. 



The single specimen that is referred here is very poorly preserved, 

 but differs markedly 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 very little forward, and is rather broader than long. 

 The antennae 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, I'eaching nearly to the tip of the abdomen. 

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

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



Length of body, 5.25™" ; including the closed hemelytra, 7""° ; breadth 

 of body, l.G""™ ; length of hind tibiaj and tarsi, 4"™.

2. STENOPAMERA gen. nov. (ozeyo?, Pamera, noni. gen.). 



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

 times longer than the posterior, but which by its bullate form is even wider 

 tlian it, the postei'ior lobe being reduced to a mere narrow belt. The whole 

 insect is of compact oval form, less than thre<^ times longer tlinn Innad. In 

 the last respect it reminds one of Trapezus, but in its principal features it 

 seems to be most nearly allied to Pamera. The antennsE are scarceh' longer 

 than the extreme width of the body and scarcely have the apical joint
