Sulcacis Icngi, n. sp. 



Oblong, oval; cylindric in form; piceoiis black, subopake. 

 Bristling with pale setae, arranged without order. Head sparsely 

 punctate; flat in front, with a well-marked sulcation across 

 clypeus, which is slightly produced in front. Antennae 9- 

 jointed, with a 3-jointed club. Club joints rounded, slightly 

 transverse, with a deep fovea on each side. Third joint elongate, 

 as long as the fourth and fifth combined. Sixth very short, 

 much wider than long. Prothorax as long as wide. Sides 

 rounded and margined, as is base. Apex rounded and simple 

 in both sexes. Elytra one and one-half tjmes as long as wide; 

 wddest behind middle and evenly rounded to apex. Beneath the 

 prosternum is flat between coxae and strongly transversely 

 excavated in front. The male has a round fovea on first ventral 

 segment, with a row of bristles around it, ])ointing inwards. 

 Length 1-08 mm. Vermont. From Chas. Leng. Cincinnati, 

 Ohio, abundant. The excavated prosternum jioints strongly 

 towards Brachycis. It also resembles Plesiocis, the type of 

 which is a California species. 



Sidcacis niyer, n. sp. 



A species allied to lengi. Jet l)lack and more shining and 

 of more cylindrical form. Punctuation and bristles coarser 

 and sparser. The bristles white in color. Prosternum narrower 

 betAveen coxae. Antenna! joints differently proportioned, the 

 third joint being as long as the fourth, fifth and sixth combined. 

 The seventh and eighth joints wider than long. The ninth 

 joint only being circular. Length 1.05-08 mm. Three speci- 

 mens. Southern Illinois. I have received from Mr. H. W. 

 Wenzel, of Philadelphia, a species taken by him in Del. Co., 

 Pa., that is perhaps a race of the above. It has finer ])unctu- 

 ation and more abundant bristles, which are more yellow in 

 color. More specimens, from intermediate points may show 

 that there is only one species.
