dentate. The eyes are well developed, more convex than in the 

 preceding genus or Lobomeiopoti and less finely faceted, though 

 only moderately prominent and, as in Pechalius^ without vestige 

 of supra-orbital carinas. The head is relatively smaller than in 

 any of the preceding genera, with large, angulate or strongly 

 ogival epistomal lobe, the prothorax narrowed and deeply sinu- 

 ate at apex, with acute angles and also somewhat narrowed 

 toward base, the elytral humeri being evidently exposed basally. 

 The upper line of the epipleurae attains the very acute sutural 

 angles, becoming more posteriorly prominent than the lower 

 margin, and the tarsi have dense pads of fine pale pubescence 

 beneath, the posterior slender, with the fourth joint gradually 

 thicker from base to apex, the claws strongl}' arcuate and stout. 

 We have a number of species in our Floridian region as fol- 

 lows : — 



Mesosteruum rather deeply and very distinctly impressed 2 



Mesosternum equally tumid but with scarcely a vestige of impression.. 7 

 3 — Lateral lobes of the front very short, obtuse and inconspicuous... 3 

 Lateral lobes slightly prominent and very narrowly rounded 6 



3 — Pronotum with feeble impressions at base near lateral fifth or 



sixth ; femora minutely and sparsely punctate 4 



Pronotum without very evident basal impressions ; size small ; femora 

 less finely but rather sparsely and strongly punctured 5 



4 — Body larger in size, elongate, fusoid, very acutely and gradually 



pointed behind, dark piceous, the legs and antenna; dark rufous, 

 polished, the pubescence long, yellowish-white, sparse anteriorly, 

 disposed in small condensed patches which are arranged linearly 

 on the elytra; head sparsely punctate, very nearl}' as wide as the 

 distance between the thoracic angles, which are acute and sharp 

 but not prolonged ; prothorax barely one-half wider than long, 

 widest just before the middle, the sides rounded, converging 

 anteriorly, feebly converging and nearly straight or feebly sinuate 

 to the obtuse but not blunt basal angles, the apex deeply sinuate, 

 barely three-fifths as wide as the base, the surface convex, finely, 

 sparsely punctured medially, less finely, rather closely anteriorly, 

 sparsely but rather coarsely laterally, the punctures attended by 

 short carina; near lateral fourth to sixth, then close and slightly 

 rough to the sides, the basal impressions very small and adjacent 

 to the hind margin ; scutellum small, as long as wide, ogival 

 behind; elytra two-thirds longer than wide, the sides broadly, 

 evenly arcuate to the obtusely rounded humeri, which are evi- 

 dently exposed basally, with the callus small and feeble, the punc- 

 tures moderately large, close-set in even series which become
