328 Goleopterological Notices, V. 



head rnfo-piceoiis ; elytra and abdominal apex black ; legs very pale ; antennae 

 feebly infuscate toward tip ; punctures throughout extremely minute, dense 

 but scarcely visible, rather more distinct on the elytra ; pubescence consisting 

 of extremely short fine appressed hairs, distributed thickly over the entire 

 surface including the abdomen, becoming sparse toward the apex of the latter. 

 Head as long as wide, not quite as wide as the prothorax, deflexed ; eyes 

 moderate, prominent, at one-half their length from the base ; depressed epis- 

 toma polished, glabrous ; antennse extending nearly to the tip of the elytra, 

 rather thick, loose, cylindrical, pubescent but without bristling set?e, basal 

 joint small, stout, pyriform, third longer than the second, obconical, not twice 

 as long as wide, its apex oblique, four to ten somewhat asymmetrically obconi- 

 cal, tenth as long as wide, eleventli small, conoidal, not as long as the two 

 preceding. Prothorax transverse, three-fourths wider than long, widest at 

 apical third where the sides are strongly rounded, becoming parallel and 

 straight in basal half; base and apex equal, broadly arcuate; basal angles 

 obtuse and slightly blunt ; disk rather abruptly declivous laterally, the 

 median half from base to apex occupied by a v^ry large deep indentation, 

 which does not differ in sculpture or vestiture. Elytra large, one-half wider 

 than long, one-half wider and one-half longer than the prothorax ; sides feebly 

 divergent and straight ; humeri broadly exposed. Abdomen much narrower 

 than the elytra, parallel, the three basal segments broadly, deeply impressed, 

 polished and glabrous at base ; fifth shorter than the fourth. Length 2.8 mm. ; 

 "width 0.8 mm. 



New York. 



The male, from which this description is taken, has the posterior 

 part of the first tergite broadly, feebly swollen. The second bears 

 a large strongly elevated tubercle, occupying median third, the 

 posterior wall of which is vertical, clothed with longer hair and 

 having its face furrowed from summit to base ; the anterior wall is 

 likewise vertical and its foot is at the margin of the impression. 

 The third segment also has a strongly elevated abrupt elevation, 

 occupying a little more than median third and apical two-thirds, the 

 upper surface of which is flat and declivous posteriorly throughout, 

 its anterior wall vertical and deep. I have not seen the female. 



IV. lugublis n. sp. — Moderately stout and convex, somewhat shining; 

 punctures throughout almost invisible ; pubescence extremely minute, mode- 

 rately dense ; body black, the elytra feebly piceous ; legs piceous-black, the 

 tarsi slightly paler ; antennse dark red-brown. Head as long as wide, deflexed, 

 nearly as wide as the prothorax ; eyes moderate ; antennse thick, extending 

 to the middle of the elytra, the basal joint thick and pyriform, much shorter 

 than the next two, second small, a little longer than wide, third large, rather 

 wider than long, asymmetric, four to ten scaicely differing in width and about 

 as wide as the apex of the third, tenth more than one-third wider than long, 

 eleventh moderate, conoidal, not quite as long as the two preceding. Pro-
