4. Procydnus quietus. 



Head nearly one-half as broad as the tliorax, well rounded, half as broad 

 again as long. Thorax siibtrapezoidal, tapering from the base at first 

 slightly, afterwards a little more rapidly, so that the sides are a little arcuate, 

 and the rounded anterior lateral lobes rather prominent from the deep almost 

 angular emargination of the front, whicli is hardly more than a third the 

 width of thorax, and only a little more than twice as broad as deep ; surface 

 apparently smooth, punctate along the lateral margin. Scutellum nearly 

 two-thirds as broad as the thorax, reaching less than half-way to the tip of 

 the abdomen, the apex nearly rectangular, the surface punctate, somewhat 

 shorter than broad. Hemelytra with the coriaceous corium hardly occupy- 

 ing more than half the wing, serially punctate, of a testaceous color, the 

 membrane faintly infumated. Tibite densely spiny. Abdomen full, broadly 

 rounded, a little longer than broad. 



Length, 4.1-4..')'"'"; breadth, 2.4-2.6'"'". 



Florissant. Eight specimens, Nos. 2060, 6812, 7652, 10092, 10174,

5. Procydnus reliquus. 



Head rounded, broader than long, nearly half as broad as the thorax. 

 Thorax nearly three times as broad as its middle length, tapering from the 

 base, the sides considerably arcuate, with scarcely any sign of an anterior 

 lateral shoulder, the emargination of the anterior border half as broad as 

 the base of the thorax, shallow and uniform, followed by a median arcuate 

 sulcation half as broad as the emargination and equally deep ; the surface 

 is apparently quite smooth, but there are signs of punctuation at the extreme 

 lateral margins. Form of the scutellum not evident, but apparently exactly 

 as in the last species. Corium of hemelytra reaching considerably beyond 

 the middle. Abdomen full Ijut considerably longer than broad. Whole 

 body uniformly dark, the corium of hemelytra dark testaceous.
