550 Goleopterological Notices, VII. 



Besides the absence of long bristling setae toward the abdomi- 

 nal apex, this species differs from the other two in lacking the 

 long, erect lateral seta near the base of each elytron, in having the 

 abdominal segments equal in length, the fourth and fifth being 

 more elongate in tarsalis and pilicornis, and in the more evenly 

 rounded sides of the prothorax.

Faronini. 



MEGARAFONUS n. gen. 



In this genus the third antennal joint is very small, as in the 

 European Faronus, the metasternum extremely short, the abdomen 

 large, with the first three dorsals subequal in length, the fourth 

 larger and the first not modified on the disk. From Rafonus it 

 differs in its more abbreviated elytra, still larger first dorsal, in 

 having the antennal tubercles separated by an anterior extension 

 of the frontal pit, and the third antennal joint much smaller; it 

 further differs in having the fourth palpal joint more broadly oval 

 and compressed. Other generic characters are included in the 

 description of the single known species below. 



M. ventralis n. sp. — Eather broadly subcuneiform and depressed, gradu- 

 ally wider from tbe front to near the tip of the abdomen, polished, impunctate 

 and dark rufo-testaceous throughout, the legs and antennse paler; pubescence 

 moderate in length, rather coarse and abundant, recumbent. Head somewhat 

 small, exclusive of mandibles rather wider than long, scarcely % as wide as the 

 prothorax, the eyes moderate in size, slightly convex and somewhat prominent, 

 at rather more than their own length from the base, the tempora behind them 

 circularly rounded to the neck, slightly less prominent than the eyes and be- 

 coming parallel near them ; surface moderately convex, with two strong nude 

 and isolated fovese at basal fourth, separated by }-^ of the entire width; frontal 

 fovea deep and abrupt, with its floor minutely rugose and flat, prolonged pos- 

 teriorly and narrowed to a slight terminal enlargement at the centre of the 

 vertex, and narrowed anteriorly, crossing the froutal margin, the latter wide 

 between the autennie, the tubercles extremely feeble; clypeus extremely small, 

 being simply a fine porrect and strongly rounded margin at the foot of the 

 subvertical front between the antennal cavities; labrum strongly transverse, 

 broadly arcuate and subcarinate at apex, except at the sides, which are ob- 

 liquely and briefly produced and bristling with coarse sparse setse, the base 

 much narrower than the apex; mandibles very strongly thickened and exter- 

 nally angulate at base, the apical portion subtrausverse and finely acuminate, 

 the internal edge very minutely subserrulate; under surface evenly convex, 

 without trace of axial suture, the neck deeply impressed, transversely and
