NORTH AMERICAN COLEOPTERA. 27 



F. bioolor Mels. — Oblong, moderately elongate, slightly narrower poste- 

 riorly ; ferruginous brown, feebly shining, the thorax more opaque, sparsely 

 clothed with short fulvous pubescence ; antennte slender, filiform, not at all den- 

 tate, nearly as long as half the body, joint second small, third one and a half 

 times the length of the fourth, joints four to ten gradually longer; head convex, 

 coarsely, densely and rugosely punctured, a slight depression above the base of 

 the clypeus, the interocular carina extending slightly on the base of the clypeus ; ' 

 the latter very little narrowed at base and wider than the distance to the eyes ; 

 thorax with the width and length about equal, the sides feebly arcuate and nar- 

 rowing at apical third, hind angles scarcely prolonged, disc convex, sides strongly 

 deflexed in front, a feeble median impression posteriorly, surface densely punc- 

 tate, slightly opaque and rugose ; elytra striate, intervals slightly convex, densely 

 rather finely punctate and slightly rugose, epipleurse smooth, longitudinally ex- 

 cavated ; body beneath and legs paler than above, the punctuation moderately 

 dense and coarser in front ; mesopleur?e sparsely punctate in posterior half, 

 nearly smooth in front ; hind coxal plates gradually but much broader internally, 

 the free edge angulate ; claws broadly toothed at base. Length .32 - .46 inch ; 

 8-11.5 mm. 



This species resembles orchesides in form, but may be known by 

 the slender antennae and the smooth sulcate epipleurse. This species 

 is without doubt the same as that subsequently described by Chev- 

 rolat as luridus. The information given by me to Bonvouloir that 

 bicolor was synonymous with orchesides was erroneous, from the fact 

 that the type of LeConte's description of bicolor was an orchesides. 

 Since that time the type of Melsheimer has been seen, and is the 

 species above described. 



Occurs from the Middle States southward, and, according to Bon- 

 vouloir, in Cuba. 



F. iiifolix n. sp. — Form subcylindrical, parallel, very obtuse in front, nar- 

 rower only at apical third, color ferruginous brown, subopaque, sparsely clothed 

 with short yellowish pubescence ; antennse paler, slender, nearly as long as half 

 the body, feebly serrate, joint second small, third a little longer than the fourth, 

 joints four to eleven gradually longer; head convex, coarsely densely and 

 roughly punctured, without trace of interocular carina; clypeus slightly nar- 

 rowed at base, but not broader than the distance to the eyes ; thorax very dis- 

 tinctly broader than long, sides posteriorly feebly arcuate but not convergent, 

 rounded near the front angles, disc convex, coarsely, densely and roughly punc- 

 tured, a vague depression each side of the base, hind angles slightly prolonged, 

 not acute, lateral margin distinctly double from apex two-thirds to base ; elytra 

 striate, intervals slightly convex, moderately densely punctate and quite rough 

 near the base, epipleurse roughly punctate, not sulcate ; prosternum shining, 

 punctuation coarse but distant, the triangle with inner side shorter than the 

 base, surf^ice densely, coarsely punctured ; antennal groove very deep and smooth, 

 open posteriorly, very distinctly wider in front ; mesopleurte moderately, densely, 

 finely punctate in anterior half, very smooth posteriorly ; metasternum and ab- 

 domen moderately, densely punctate ; hind coxal plate gradually wider inter- 

 nally, the free angle rounded ; claws broadly toothed at base. Length .36 inch ; 

 9 mm.
