H. C. FALL. 119 



The greater part of the specimens seen were collected by Hub- 

 bard and Schwarz. 



This species has been suppressed as the equivalent of fulvipennis 

 Mann. ; while this course may be correct, the synonymy does not 

 seem to me to be sufficiently well established. 



Ii. lira I iin Lee. — Oastaneous, legs and antennae a little paler, glabrous, shin- 

 ing throughout. Head coarsely and densely punctate, longitudinally silicate, the 

 sulcus broader and deeper posteriorly; tempora parallel, usually nearly half as 

 long as the eye, their hind angles right and scarcely rounded ; antenna 4 nearly 

 or quite attaining the hind angles of the pronotum, rather slender, joints all 

 longer than wide, except the tenth, which is as wide as, or a little wider than 

 long. Prothorax a little wider than the head, a little longer than wide, sides 

 sinuately and moderately to rather strongly convergent from the lobed anterior 

 angles to beyond the middle, thence slightly diverging to base; surface rather 

 coarsely and somewhat irregularly punctate; margin reflexed, disk with two 

 entire longitudinal costae, which are nearly parallel in basal two-thirds, then 

 arcuately divergent and showing a tendency to curve inward and unite along 

 the anterior margin. The transverse subbasal impression is distinct and divided 

 by the costae into three broad depressions. Elytra broadly ovate, the side mar- 

 gin explanate, tips separately rounded and scarcely produced ; disk broadly 

 impressed behind the base, striae coarsely puuetate, the punctures distinct to the 

 apex, though gradually smaller posteriorly ; intervals a little convex, -the third a 

 little prominent at base, and the seventh more noticeably elevated— though not 

 carinate — in basal half. Under surface subimpunctate and shining throughout; 

 the metasternum with short, more or less distinct rugae radiating from deep 

 post-coxal foveae ; ventral segments very finely reticulate, except along their 

 apical margins. (PI. Ill, fig. 131. Length 2 mm. 



Hab. — New Hampshire; Vermont; Rhode Island; Massachu- 

 setts ; New York ; Canada ; Pennsylvania ; West Virginia ; Illinois ; 

 Michigan ; District of Columbia. 



A common species throughout the Northwestern United States 

 and Canada. There are no external sexual characters. 



C'ONINOMUS Thorn. 

 This genus is closely allied to Lathridius, and though accepted 

 by LeConte and Reitter, is more recently given only subgeneric 

 standing by Belon. The prosternal process, however, here reaches 

 the hind margin of the prothorax, completely separating the epimera, 

 and according to the value we have chosen to ascribe to that charac- 

 ter (I am not at all sure that its importance has not been overesti- 

 mated), the two genera must be held as distinct. The very deeply 

 incised prothorax gives to the members of Coninomus a facies which 

 is not closely approached by any species of Lathridius known to me,* 



* According to Belon Lathridius alternatus lias the thorax nearly as deeply 

 incised.
