greatly from the following, and the abdominal segnaents are very 

 different in relative proportion. In structure of the mesosternal 

 side-pieces, they should be placed in different divisions, according 

 to the scheme adopted by Dr. Horn. 



Tanymecus confertus, Gyll. — Very abundant at Austin, Texas, in June. 



Aramigus FuUeri, Horn. — One specimen, San Francisco, Cal., Mr. Har- 

 ford. 



Aphrastus unicolor, Horn. — Extremely abundant at Austin, Texas, in 

 June. 



Scythropus calif ornicus, Horn. — Abundant near Sacramento, Cal. 



Endiagogus pulcher, Fahrs. — Not very abundant at Houston, Texas, In 

 February, generally under bark.

A. laticollis n. sp. — Three-fourths longer than wide, convex, pale 

 yellowish throughout, except the antennae and metasternum, which are 

 piceous-black ; pubescence sparse, short, semi-erect, whitish in color. 

 Head short and robust, much wider than long, broadly, evenly convex, 

 coarsely, not densely, and very feebly punctate toward the sides, im- 

 punctate in the middle, feebly convex between the eyes ; the latter 

 large, convex and prominent ; sides behind them very short, parallel 

 and nearly straight ; beak twice as long as the head and scarcely one- 

 third as wide, arcuate, cylindrical, with a very few coarse, feeble 

 punctures at the sides; lateral sulcations moderate, almost impunc- 

 tate, scarcely at all visible from above ; upper surface with an elongate 

 fovea between the antennae ; the latter rather robust, as long as the 

 beak, inserted just beyond the basal third of the latter ; club robust ; 

 basal joints but slightly thicker than the f unicle. Prothorax widest at 

 basal third, nearly one-half wider than long ; sides strongly arcuate 

 toward base, more strongly convergent and straighter toward the apex; 

 the latter broadly, very feebly arcuate, three-fourths as wide as the 

 base ; the latter broadly, evenly, and feebly arcuate ; disk evenly and 

 feebly convex, finely, feebly, sparsely, and somewhat unevenly punc- 

 tate. Flytra somewhat dehiscent at apex, two-fifths longer than wide,

 straight ; humeri narrowly rounded ; disk convex, feebly impressed 

 along the suture toward base, coarsely, feebly and sparsely punctate.
