flat tubercle and straight to the antennae; face from the end of the 

 clypeus to the shght tubercle, strongly arched transversely, and al- 

 most triangular in section, but spreading out to form a triangular flat 

 area below and between the antennae, this area faintly grooved down 

 the middle; the ridges bounding the antennal pits plainly extending 

 to the lateral ocelli, and most prominent opposite the median ocellus. 

 Head in one specimen dark red, overspread with blackish, especially 

 around the antennae and over the cheeks; an oval lighter spot just 

 below the frontal tubercle, lighter below the inner lower corner of 

 the eyes, and almost the color of the body behind the upper half of 

 the eyes. In the second specimen the head is red, overspread \vith 

 blackish, with a band, broadest at the ends, across the face opposite 

 the lower half of the eyes and a large area behind the upper half of 

 each eye, the color of the body; head distinctly punctate, and clothed 

 with long whitish pile, the punctures larger below and between the 

 antennal pits; eyes relatively rather small; ocelli arranged in a tri- 

 angle with the two lateral ocelli somewhat nearer to the median than 

 to each other; antennae about 6.5 mm. long, black, segments one and 

 two shining, punctured and hairy, the rest duU and hairy; 36-seg- 

 mented (one antenna); labrum black, shining, relatively broad, 

 somewhat more punctured and hairy than the face ; mandibles black, 

 palpi black, aU of the segments at least approximately cylindrical. 



Thorax. — Longer than high, red; tegulae and venter black; pro- 

 no tum shining, closely and finely punctate and hairy along margins, 

 the pits above large, elongate oval, pointed below and followed by a 

 few indistinct vertical ridges in the depression of the lateral lobes of 

 the pronotum; reddish yeUow; cephalic margin black above, in the 

 middle, and near the lower ends of the lateral lobes; proepisterna 

 darker, the lower ends of the lobes broadly black; mesonotum shining, 

 rather finely and sparsely punctate and hairy, the parapsidal furrows 

 large and deep, but broad and not sharply limited, straight, meeting 

 just before the scutellar fossa, with a slight median depression run- 

 ning to the fossa; median lobe broadly grooved, the middle of the 

 groove slightly elevated, lateral lobes broadly flattened, hind angles 

 of mesonotum produced into nearly vertical, almost triangular plates, 

 prescutellar fossa deep, with a large median longitudinal carina, and 

 a much smafler incomplete one on each side; scuteUum triangular, 

 truncate behind, the sides rounded off; mesopleurae shining, sparsely 

 punctate and hairy, the mesopleural furrow straight, length equal to 

 about one-half the width of the pleurae; deep and strongly crenulate; 

 venter smooth, hairy, black; upper part of metapleura smooth, 

 shining, punctured, and hairy; lower third coarsely rugose; profile of 

 propodeum uniformly curved to the insertion of the abdomen, with 

 six carinae, the two median nearly parallel, converging sMghtly in 

 front, meeting before and behind in a definite angle, with three trans-
