3. TELEOSrHISTUS PLACATIIS. 

 PI. 28, Fig. 3. 



Head not preserved on the sino-le specimen known. Thorax blnntly 

 punctate throughout, mostly rather coarsely, besides which the surface is 

 more or less roughened except just in advance of the scutellum, where it is 

 smooth, and the punct* rather fine and a little sharper. Scutellum reach- 

 ing barely two-fifths way to the tip of the al)donien, uniformly punctate 

 throughout like the greater part of the thorax. Corium of hemelytra 

 rather sharply, deeply, very uniformly and not very s])arseiy punctate, the 

 punctse with a tendency to a longitudinal arrangement. Body griseons, 

 corium of hemelytra griseo-castaneous, the clavus and costal field of corium 

 darker, a pallid line following the sutura clavi, and, less distinctly, the lower 

 edge of the principal costal vein and the outer margin of the broadly sinu- 

 ous marginal suture ; membrane slightly infumated with a small but distinct 

 dark triangular coriaceous spot at extreme inner base. 



Length (without head), 12.75""" ; breadth at base of hemelytr?, 6.75""'. 



Florissant. One specimen. No. 546 <>. 



2. THNETOSCHISTUS gen. nov. {dvrfTo?, 6xigt6<;). 



Body moderately slender with nearly parallel sides. Head with prom- 

 inent moderately large eyes, scarcely broader than long, less than half the 

 width of the thorax, scarcely shorter than it, the portion in front of the eyes 

 as long as the part behind them, tapering, subtriangular, bluntly pointed, 

 the tylum distinctly surpassing the juga; antennas with the basal joint not 

 attaining the front of the head, the second apparently just longer than the 

 thorax. Thorax two and a half times broader than long, apparently witii 

 a slight angulate prominence at the base of the sides, in front of which the 

 sides taper very rapidly, forming one curve with the broadly rounded front, 

 which has no eniargination for the reception of the head. Scutellum tri- 

 angular with straight sides and bluntly angulate, not produced apex, con- 

 siderably longer than the thorax, Init not reaching half-way to the apex of 

 the rather elongated produced abdomen. 



A single species is known.
