becoming obliterated toward tip, the pubescence short, moderately dense; each 

 strial interval with a single series of suberect hairs. Length 2.25-2.7 mm.; width 

 0.85-I.15 mm. Vermont to Washington Slate, P'lorida and Te.xas 



fumata Linu. 



The single specimen with dark elytra is from Palm Beach, Florida, 

 and seems to have the prothorax slightly less transverse and the an- 

 tennal club a little thicker ; additional material may ultimately prove 

 it to represent a variety or closely related species. -^ 



Litargus Erichs. 



This genus differs profoundly from the two preceding in the form 

 of the epipleurge, but the eyes are nearly as in Tritoma and the anten- 

 nae have a loose 3 -jointed club as in Typhcra. The ornamentation of 

 the elytra is similar to that of Tritoma, and the body is very small in 

 size. The species are rather less numerous than in Tritoma and may, 

 as far as discovered, be separated by the following characters : — 



Elytra with the pubescence short and sparse but stiff, pale in color and arranged 

 throughout in even approximate series, piceous to blackish in color, each with a 

 large transversely oval discal spot near basal and apical fourth, the posterior ap- 

 proaching more closely to the suture ; punctures sparse throughout, the body 

 rather broadly oval, convex and shining, the pronotum not impressed at base but 

 with the basal sinuation at each side of the middle distinct ; last antennal joint 

 short, rounded, the labrum small ; epistomal suture wholly obsolete. Length 

 1.7-2.0 mm.; width 0.85-1.2 mm. Rhode Island to Texas and Lake Superior.

Elytra with the pubescence in general confusedly arranged 2 



2 — Elytra with fine dark pubescence, closely punctulate and with widely separated 

 single series of longer semi-erect and paler hairs, each with a small subbasal spot 

 at three-fifths from the suture, a larger triangular subsutural spot at two-sevenths 

 and an obliquely oval subsutural spot at five-sevenths, the pale spots clothed also 

 with pale hairs ; pronotum finely, not very densely punctate, the punctures simple 

 and not asperate, feebly biimpressed at base ; body elongate-oval and depressed ; 

 last antennal joint short, narrowly rounded at tip ; labrum large and very trans- 

 verse. [Litargus in sp. ; type eoiiiiexiis'\. Length 2.2 mm.; width i.i mm.

Var A — Similar but with the rows of erect paler hairs only evident toward the 

 sides of the elytra, the basal spot more oblique, the anterior subsutural 

 smaller, rounded and more distant from the suture, the elytra relatively less 

 elongate, the spots subobsolete occasionally. Length 1.8-2.2 mm.; width 



0.9-1.2 mm. New Jersey and Indiana obsolescens, v. nov. 



Elytra without widely separated series of pale hairs 3
