Maklin, who states that the prothorax is quadridentate at each side ; 

 this would not apply to the 6-dentatus, described above, unless the 

 author included the basal angles and these are in no respect dentiform 

 in the latter species. 



Cryptophagus Hbst. 

 This is a large genus, including some of the larger and more con- 

 spicuous species of the family ; they are easily separable among them- 

 selves but rather difficult to classify in a satisfactory manner. The 

 body is oblong-oval, convex, strongly punctured and always coarsely, 

 distinctly, though not densely, pubescent, the elytra having in addition 

 some longer hairs, which are frequently very conspicuous and always 

 subserial in arrangement, although the punctuation may, and usually 

 does, exhibit no trace of series. The antennae are moderate in length, 

 thick, with the club abrupt, parallel and loosely 3 -jointed. The 

 prothorax is wider than long, subparallel anteriorly and narrowed 

 toward base from about the middle, where there is a more or less dis- 

 tinct acute and reflexed marginal tooth, and the apical angles are 

 thickened and obliquely truncate, the oval truncature sublateral, pol- 

 ished, generally fiat or rarely concave and foveate at the middle ; the 

 lateral edges between the submedian denticle and the well-defined and 

 sometimes subprominent basal angles is generally obsoletely serrulate ; 

 the disk is deeply, though finely, bifoveate at the base, the fovese 

 connected by a fine groove following the basal margin and often sub- 

 interrupted at the middle by a fine longitudinal carina. There are 

 also quite generally visible two small impunctate and feebly callus-like 

 spots at each side near lateral third. The maxillary palpi are well 

 developed, the last joint elongate and gradually, somewhat obliquely 

 and obtusely acuminate, the last joint of the labial moderately stout, 

 oval and truncate at tip, the mentum large, transverse, the basal parts 

 concave and punctured and separated from the deflexed apical parts 

 by a strong, transversely arcuate carina, which is prolonged anteriorly 

 on the median line to the extreme apex. The anterior coxae are 

 obliquely oval, rather large and deep-set, and the intercoxal process 

 is prolonged posteriorly, with its free tip ogivally acuminate and dor- 

 sally margined. The mesosternum is broadly and feebly concave. The 

 tarsi are slender, and the abdominal segments two to four decrease 

 gradually in length, the first longer, generally exceeding the next two 

 combined, the fifth about as long as the second and rounded in both
