568 Goleopterological A'otices, VII. 



Besides the tibial character before referred to, the anterior 

 femora of the male above described are moderately, the interme- 

 diate very strongly, swollen, the upper contour of the latter 

 strongly arcuate, the lower very feeblj' sinuate toward the middle ; 

 the posterior trochanters are acute at tip, the abdominal charac- 

 ters extremely feeble and the ventral pygidium lai-ge. The female 

 ditfers but little, the head being only slightly smaller than in the 

 male. 



This minute species is allied to j^arvula, but differs in the elon- 

 gate occipital impression, which takes the form of a fine sulcus 

 extending anteriorly to a point midway between the fovese. In 

 parvula, which was described from a unique taken in the neigh- 

 borhood of Charleston, S. C, the transverse sulcus of the prono- 

 tiim is said to be nearly straight; in sulcatula it is distinctly 

 though broadly angulate. It is probable that the Trimium par- 

 viilum, described by Dr. Brendel in his revision of the genus Trim- 

 ium, is the present species or one closely allied. 



M. fossiger n. sp. — Moderately stout and ventricose, strongly convex, 

 polished and impunctate throughout, pale brownish-testaceous, the legs and an. 

 tennse slightly more flavate ; pubescence rather coarse, short, subdecunabent, 

 only moderately abundant. Head very slightly narrower than the prothorax, 

 as long as wide, the eyes moderate in prominence, rather small, at much more 

 than their own length from the base, the tempora behind them but slightly 

 less prominent, long, feebly arcuate and but just visibly convergent to the 

 base, the angles well defined though rounded ; base distinctly impressed at the 

 middle, the impression not prolonged forward to the vertex ; foveas large, 

 moderately deep, nude, situated just behind the middle and separated by 

 nearly }4 the total width, united by a very feebly impressed ambient sulcus, 

 which is not materially enlarged behind the slightly tumid frontal margin ; 

 antennal prominences small but rather distinct ; antennae % longer than the 

 head, the second joint oval, distinctly larger than the first, ninth but little 

 wider than the preceding, transversely cuneiform, tenth distinctly wider, very 

 short and transversely lenticular, virtually symmetric, the eleventh as long 

 as the five preceding combined and twice as wide as the tenth. Prothorax 

 distinctly wider than long, the sides parallel and circularly arcuate anteriorly, 

 strongly convergent and sinuate toward base, the sulcus strong, only mode- 

 rately cuspid posteriorly at the middle. Elytra distinctly shorter than wide, 

 }4 longer and more than % wider than prothorax, the sides strongly divergent, 

 strongly arcuate especially behind the middle, where they are materially wider 

 than at apex ; humeri slightly exposed, the plica narrow and pronounced ; 

 basal fovea large, elongate, gradually attenuate and extending fully to the 

 middle of the disk. Abdomen a little longer and narrower than the elytra, 

 convex, the dorsals equal toward base, the first with two slender, flat,
