334 MEMOIRS ON THE COLEOPTERA 



with three or four small dark spots; elytra densely cinereous, with 

 small sparse punctures and a large basal area, a short lateral oblique 

 disintegrated fascia near basal third, a large oblique spot, not at- 

 taining the suture, solid and well defined at apical third, and a 

 smaller and sharply denned marginal spot near the apex, brownish- 

 black; last dorsal (9) nearly four times as long as wide, parallel, 

 with feebly arcuate sides, gradually converging posteriorly to the 

 bluntly rounded apex. Length ( 9 ) n. 8 mm.; width 4.4 mm. Ohio. 



triangulifera Hald. 



The last two species are rare in collections and I have at present 

 but a single female of triangulifera. One male of fasciata of my 

 series has a narrower outline, with relatively larger prothorax, more 

 nubilate markings and more narrowly sinuato-truncate elytral 

 apices, than any other, but additional examples are essential before 

 coming to any conclusion concerning it. Hebes doubtless represents 

 Leiopus biguttatus in many collections, but reasons are given in the 

 footnote on p. 332 for concluding that there can be no such identity. 

 The length of biguttatus, as given by LeConte, is 8.2 mm.; possibly 

 the elytral tips may be narrowly truncate. 



Graphisurus Kirby. 



The species hitherto placed under Acanthocinus in our lists form 

 an isolated group, having composite characters and affinities, which, 

 as explained above under Urographis, should now take the name 

 Graphisurus Kirby. The prominences of the prothorax, for in- 

 stance, are not dentiform as in Urographis and the European 

 JEdilis edmondi (Acanthocinus) as figured by Duval, but truly spini- 

 form, more as in the Lepturgids, and are generally more posterior 

 in position than in either Urographis or Acanthocinus, though never 

 quite so nearly basal as in Lepturges, and the antennae are very long 

 and filiform as in the latter group, but the body is very different in 

 facies, being relatively larger in size and with radically different 

 type of ornamentation, the latter more remindful of Urographis. 

 In the dense inferior fringe of hairs of the antennal joints, it however 

 differs from all of the other American genera, the only vestige of this 

 fringe in the latter being a very few short erect stiff black setae, one 

 to three or four perhaps on each joint, not constituting an analogy 

 in any sense. The elytra have no erect hairs as they do in Uro- 

 graphis, this feature being present among Lepturgid genera omit-
