8. Rhyssemus ccdatus Lee. Brown, nearly black. Antennae and palpi 

 yellow. Head slightly emarginate in front, covered with granules, vertex 

 with two oblique lines nearly meeting, and a slight elevation in front of 

 them. Prothorax slightly wider than long, sides straight, margined ; hind 

 angles and base rounded, the latter distinctly margined; disc verrucose, with 

 four transverse grooves, of which the first and second are entire ; the third 

 is the widest and deepest, and is expanded at the middle into a triangular 

 impression, which divides the two posterior elevated ridges. Elytra oblong, 

 feebly rounded on the sides, striae double, catenately punctured, interspaces 

 with two rows of small granules. Length 2.5 mm. One specimen. Re- 

 sembles Eh. riparius Horn, but the second transverse groove of the pro- 

 thorax is entire. 



Collected in Santa Fe canon, New Mexico, by the Kansas University Sci- 

 entific Expedition for 1880; also found by Mr. E. A. Schwarz, at Cheyenne, 

 Wyoming. 



9. Rhyssemus sonatus Lee. Black, opaque. Head and prothorax finely and 

 densely granulate, the former convex, without ridges; emarginate in front, 

 as usual, with the angles well defined ; prothorax one-half wider than long ; 

 sides broadly rounded, margined, narrowed and subsinuate near the base, 

 which is broadly rounded and not margined ; transverse grooves very feeble, 

 the first and second entire, the third and fourth connected with a very slight 

 dorsal channel. Elytra oblong, scarcely rounded on the sides ; strise double 

 and catenately punctured, as usual; interspaces narrow, subcostate, each 

 with two series of granules. Very distinct by the obsolete impressions of 

 the prothorax, which are very much less apparent than in Rh. Calijornicus. 



One specimen was found by Mr. A. Bolter, near Chicago. 



10. Lebasiella discoidea Lee. Head, prothorax, antennae and legs bright 

 ferrugineous; discoidal spot of prothorax black, club of antennae, knees, and 

 ends of tarsal joints blackish; elytra blue, densely and strongly punctured; 

 under surface of trunk and abdomen black. Length 5.5 mm. 



One specimen, collected in Santa Fe canon, New Mexico, by the Kansas 

 University Scientific Expedition for 1880. Resembles L. maculicollis, but 

 diflTers by the head, legs and part of antennae being ferruginous, and by the 

 elytra more densely punctured, 



11. Pristoscelis comatus Lee. Elongate, black, with a leaden lustre, clothed 

 with long erect hairs. Head strongly not densely punctured, antennae with 

 the fourth, sixth and eighth joints a little wider than the adjoining ones, last 

 joint longer, slender and acute at tip. Prothorax not wider than the head 

 and eyes, very little wider than long, convex, rounded on the sides, which 

 are not serrate; disc strongly not densely punctured. Elytra punctured as 

 strongly but a little more densely than the prothorax. Claws with the ap- 

 pendage acute, one-third shorter than the claw. Length 4 mm. One speci- 

 men. Does not resemble any other species in my collection.
