Hymenorus planulus n. sp. 



Oblong, parallel, similar in form to occidentalh but 

 much more depressed, piceous, semi-opaque, antennae 

 and legs ferruginous. Antenna? not longer than half the 

 body, third joint longer than fourth. Head coarsely not 

 closely punctate, clypeus more densely, eyes large, nar- 

 rowly separated. Thorax one-half wider than long, sides 

 arcuate in front nearly parallel in basal half, hind angles 

 sharply rectangular, disc slightly convex, coarsely densely 

 punctured (as in occidental is). Scutellum densely punc- 

 tured. El3^tra a little wider than the thorax, sides nearly 

 parallel, gradually narrowing at apical third, the sutural 

 angle obtuse, disc flat finely striate, stria; closely finely 

 punctate, intervals flat, moderately closely punctate and 

 with short brown hair. Presternum densely punctate, 

 propleurse quite smooth near the margin. Abdomen shin- 

 ing, sparsely finely punctate. First joint of hind tarsus 

 longer than the following joints. Length, .30 inch; 7.5 

 mm. 



One female specimen evidently related to occidentalis 

 from the table given by Capt. Casey (Ann. N. Y. Acad., 

 1891, p. 86), but differing in smaller size, much more de- 

 pressed form, darker color and less pubescent surface.

Hymenorus spinifer n. sp. 



Oblong, sub- depressed, piceous, slightly shining, 

 sparsely clothed with short brownish hair, form very like 

 occidentalism but more depressed. Antenna; about half 

 the length of the body, ferruginous or piceous, third joint 

 in both sexes very little longer than the fourth. Eyes 

 large, narrowly separated, head coarsely punctured be- 

 tween them. Outer side of last joint of maxillary palpus 

 longer than the apical side. Thorax about a third wider 

 than long, sides convergent nearly from the base, more
