separated into two lobes, the anterior one impunctate and the posterior 

 one either impunctate or very finely and obsoletely so; lateral margins 

 evenly expanded throughout, most commonly pale and always im- 

 punctate, subparallel or very gently converging anteriorly, very 

 lightly or not at all sinuate behind the middle ; anterior margin nearly 

 straight; posterior margin strongly sinuate before the scutellum, this 

 margin sometimes more or less pale. Scutellum black, unicolorous, 

 flat, longer than wide, not at all or very finely punctate. Corium 

 pale, more or less suffused with fuscous and finely punctate. Clavus 

 with three irregular rows of punctures. Costal margins expanded, 

 subparallel to each other or very gently rounded. Fore femur in- 

 crassate, armed with two or three teeth lietween middle and apex, one 

 of which is frequently larger. Fore tibia nearly straight in both 

 sexes. Hind tibia with short rigid bristles. Posterior tarsus with 

 basal segment very much longer than second and third together but 

 not twice as long. 



Type Trape^onotus riifipes Stal. Here also should be placed 

 Rhyparochromus soldalicnis Uhl. and R. angustatus Van D. and a new 

 species from Lakehurst, N. J., described below. 



From Rhyparochromus Curtis (type chiragra Fab.) this genus 

 differs as follows : not pilose, pronotum transverse, lateral margins 

 more nearly parallel and the edge more evenly expanded, both lobes 

 either impunctate or the posterior one must delicately punctate, fore 

 femur not so incrassate and without the very prominent single tooth, 

 rostrum with second segment longer than third, fore tibia nearly 

 straight, posterior tarsus with basal segment not twice as long as 

 second and third segments together. 



From Trapesonotus Fieb. (type agresfis FaW. ^ arenarins Linn.) 

 this genus difl'ers as follows : both lobes of the pronotum concolorous, 

 at most with only the posterior margin pale, lateral margins more 

 nearly parallel, posterior lobe not so coarsely punctate, the fore 

 femora are differently armed, and the anterior tibia more nearly 

 straight. 



I have examined twelve specimens of Uhler's R. soldalichis from 

 Oregon, Nevada and California. I have recently received a single 

 specimen taken near the Agricultural College Station, Miss., and two 

 others collected by W. L. McAtee at Dyke, Va., which, except for the 

 more infuscated antenna, I cannot differentiate from Uhler's species.
