26 GEO. H. HORN, M. D. 



In this species the interocular carina is more distinct than in 

 Hornii, and the posterior coxal plates gradually not al)rui)tly wider, 

 these characters with the smaller second joint of the antennae and 

 the coarser sculpture will readily distinguish the two. 



Occurs in Canada and Massachusetts. 



F. molestus Bouv. — Oblong, moderately elougate, convex, very little nar- 

 rowed behind, dark reddisli brown, subopaquc, sparsely clothed with fulvous 

 pubescence ; antennse passing very slightly the hind angles of the thorax, second 

 joint small, 3-8 dentate, 9-10 more slender and not dentate, eleventh longer 

 and filiform ; head coarsely, densely and roughly punctured, without longitu- 

 dinal or interocular carinas ; clypeus broad at base, nearly twice the distance to 

 the eyes; thorax a little wider than long, sides subparallel and straight behind, 

 arcuate and narrowed to the front anteriorly, disc convex, a median longitudinal 

 impression extending from the base to the middle, also two small impressed 

 points in front of the scutellum, hind angles short, obtuse ; surface coarsely, 

 densely and roughly punctured ; elytra slightly broader behind the middle, then 

 arcuately narrowed to the apex, deeply striate, the intervals convex, densely, 

 rather finely punctate and distinctly rugose ; mesopleurse rather finely and mod- 

 erately densely punctured over the entire surface ; legs ferruginous, claws toothed 

 at base. Length .52 inch ; 13 mm. 



This species is unknown to me. It is evidently very like orchesides, 

 but has the elytra a little broader behind the middle, the antennae 

 differently formed, and the clypeus at base broader. 



The locality indicated by Bonvouloir is simply North America. 



F. orcliesirtes Newm. — Form oblong, moderately elougate, slightly nar- 

 rower behind, convex, ferruginous to piceous, feebly shining, surface clothed 

 with very short yellowish pubescence ; antenna? slightly compressed, more slen- 

 der externally, extending a little beyond the hind angles of the thorax, second 

 joint small, third not as long as the next two, joints three to ten serrate, the 

 eleventh slender and longer ; head convex, coarsely and densely punctured ; 

 clyi^eus at base a little broader than the .distance to the eyes ; thorax as long as 

 wide, sides posteriorly feebly arcuate, anteriorly obliquely narrowed to the front, 

 disc convex, the sides suddenly deflexed in front, a distinct median impression 

 at basal half, and on the basal margin each side of the scutellum a small fovea, 

 surface coarsely and densely punctured, hind angles acute, very little prolonged ; 

 elytra distinctly striate, the intervals slightly convex, the punctuation finer than 

 on the thorax, dense, slightly rugose at base, epipleurfe flat, roughly punctate ; 

 punctuation of the under side of body a little finer than on the elytra and rather 

 dense ; propleural triangle more opaque, the inner side and base equal ; meso- 

 pleurse sparsely punctate on basal half, nearly smooth in front ; hind coxal plate 

 gradually but much dilated internally; last ventral segments obtuse; claws 

 broadly toothed at base. Length .40 - .68 inch ; 10-17 mm. 



This is the largest in our fauna and one of the largest in the entire 

 genus. It varies in size as well as in color, smaller specimens resem- 

 bling, superficially, the next species. 



Occurs in Canada, the New England and Middle States.
