174 J. L. LECONTE, M. D, 



commencing about one-fifth fron) the tip, and reaching the side margin 

 behind the middle; the front outline is angulated near the side; 

 the tip is obliquely and feebly subsinuate, and the sutural angle is 

 rounded. 



I was inclined to place this species in Oxoplus, but the mandibles 

 are not emarginate at tip. 



I^eptiira aiitliracina.— Elongate, black, finely pubescent. Prothorax 

 a little longer than wide, gradually narrowed from the base forwards, slightly 

 rounded on the sides, constricted near the tip; hind angles slightly laminate; 

 disc convex, finely punctured, dorsal channel faint, posterior impression very 

 deep, base sinuate margined. Elytra narrowed from the base, obliquely sub- 

 emarginate inwards at the tip, outer angle of truncature acute, sutural angle 

 obtuse; surfiice rather finely punctured, jiunctures not much stronger at base. 

 Length 15—19.5 mm.; .6 — .77 inch. 



^. — Fifth ventral segment flattened at tip, with the angles prolonged into 

 obtuse processes; last dorsal rounded at tip; antennse five-sixths as long as 

 the body. 



9. — Fifth ventral segment slightly flattened at tip, and subtruncate; last 

 dorsal subemarginate ; antennae two-thirds the length of the body. 



One pair, Oregon. x\llied to L. plug if era Lee., (New Spec. 224), 

 but differs by the prothorax being narrower, less rounded on the sides, 

 with the hind angles more produced. The terminal processes of the 

 fifth ventral segment of the % are longer. I have not mentioned the 

 difference of color as being of specific importance because in this 

 group of the genus it has but little value. The fourth joint of the 

 a n ten n PC is nearly as long as the fifth. 



S|>alacop!<iis stolata, Newman. 



Florida and Ti xas. Well preserved specimens of this species, and 

 of snffusa have the antennae hispid beneath with long bristles, from 

 the third to the seventh joint. The first joint of the antennae in all 

 the specimens before me is nearly as long as the head and prothorax. 

 This species is hardly difierent from the Cuban Eutlieia \\jiluin, and the 

 latter genus tor which the'names Euthuorus Duval and Systene Pascoe 

 have been proposed should be suppressed. 



Tanarthrus salicola. — Depressed, ferruginous, opaque, very finely and 

 densel}' punctulate, finely pubescent. Head large, hind angles rounded, vertex 

 with a narrow indistinct smooth space, occiput with a very short impressed 

 line. Prothorax cordate, constricted near the base, dilated in front, where it is 

 scarcely narrower than its length. Elytra wider than the prothorax, dusky at 

 base and tip, and with a faint dusky transverse band at the middle. Antennie 

 with eleventh joint equal to the two preceding united, slightly constrictexl at 

 the middle. Length 3 mm.; .12 inch. 



Great Salt Lake, Utah. I owe two specimens to the kindness of 

 Mr. Ulke. Similar in form to T. salinus but much smaller and easily 

 recognized by the head and prothorax as densely punctured as the
