tion immediately behind each lateral fovea of the pronotum acute 

 aud not rounded as it is in temporalis. 



B, fossicauda n. sp. — Moderately stout and strongly convex, polished, 

 "blackisti-piceous in color, the legs and antennae testaceous, the elytra and 

 anterior parts also sometimes paler ; integuments subimpunctate, the pubes- 

 cence rather long, subdecumbent, coarse, pale and rather sparse. Head equal in 

 width to the prothorax, rather longer than wide, the base circularly rounded 

 from eye to eye, the latter rather small but convex and prominent, at distinctly 

 more than their own length from the base ; upper surface moderately convex, with 

 a feeble carina at some distance above each eye, the median carina subobsolete; 

 fovese moderate in size but very deep, nude and punctiform, situated rather be- 

 hind the eyes and remote, separated by nearly % the entire width, the impres- 

 sions subobsolete ; the surface begins gradually to slope from far behind the line of 

 the antennse, but at a point which is entirely undefined, the slope continuing 

 gradually and uniformly in a large flat surface to a broadly and subcircularly 

 arcuate apical margin far before the antennae, attaining and only a slight distance 

 above the apical margin of the clypeus, the shallow vertical wall separating 

 the two edges perfectly smooth and slightly concave ; the flat and feebly slop- 

 ing front becomes slightly elevated along the antennal cavities, and its sculp- 

 iiure consists of rather distant anastomosing elevated lines, somewhat smoother 

 sublaterally and merging gradually into coarse polygonal punctures posteriorly. 

 Antennse very short, not longer than the head and prothorax, the basal joint 

 stout but short, broadly swollen beneath, becoming impunctate ; second 

 somewhat shorter but a little thicker than the third ; sixth as long as wide ; 

 seventh a little shorter ; eighth not wider but shorter ; ninth decidedly wider, 

 ■slightly transverse, obtrapezoidal ; tenth much wider and decidedly trans- 

 verse ; eleventh not quite as wide as the tenth, a little longer than the preced- 

 ing two combined ; the tenth has on the under surface a large circular 

 cavity, extending from the base to apical fourth. Frothorax nearly as long as 

 wide, widest and rather strongly rounded well before the middle, the sides 

 strongly convergent and broadly sinuate toward base ; disk with three large, 

 deep, feebly and arcuately connected fovese and two erect spiniform processes 

 in a transverse line near the base, the lateral fovese continued anteriorly for 

 some distance in feeble evanescent depressions, the spines in fine feeble sub- 

 cariniform ridges; median line finely impressed, not extending to the apex, 

 £nely carinate between the fovea and the base. Elytra distinctly shorter than 

 wide, % longer and % wider than the prothorax, the sides divergent and very 

 strongly arcuate throughout ; humeral plica small but acutely spinose ; discal 

 impression not extending to the middle ; three basal fovese perforate. Abdo- 

 men longer than the elytra, not quite as wide, acutely ogival in form ; basal 

 carinse short, triangular, enclosing nearly }{ of the discal width. Pygidium 

 rather transverse, circularly rounded beneath, the surface strongly convex, 

 sparsely punctate, with a broad, deep, smooth and polished concave excavation 

 bordering the lower margin throughout the width. Legs rather long, the femora 

 stout, the anterior tarsi )4, as long as the tibiae, slender and compressed. Length 

 2.1 mm. ; width 0.6-0.7 mm.
