rated. Metasternum broadly truncate in front. Hind coxae, coxal plates 

 and legs as in Cryptorhopalam. 



Tlie creation of this genus is made necessarj' by the discovery of a new- 

 species which cannot be relegated to any of the existing genera. It is 

 closely allied to CryptorJiopalum from which it differs only by having a 

 long, retracted clj'peus and an antennal club vmlike anything heretofore 

 described as occurring in this family. The general form, moreover, is 

 more broadly oval than in the preceding genus. 



A. americanus, n. sp. Broadly oval, convex, black, shining, clothed 

 with moderately long, semi-erect, brown pubescence. Elytra uniformly 

 black. Abdomen, legs, and antennae rufous. Head coarsely not densely 

 punctate. Antenna? of eleven joints, of which 1 and 2 are moderately large, 

 globular, sub-equal. 3-10 small, increasing in size as they recede from the 

 head, to be joined to the basal portion of the upper edge of the large ter- 

 minal joint, which is flat, broad at base, pointed at apex, three times as 

 long as wide, a little more than twice as long as all the preceding joints 

 taken together. Thorax sparsely and finely punctate at middle, more 

 densely and coarsely at sides. Scutellum smooth and naked. Elytra rather 

 coarsely, not densely punctate, black, side margins near apex rufous. 

 Body beneath black, coarsely and moderately densely punctate, very 

 sparsely pubescent. Length .08 inch; 2 mm. (Fig. 62.)

ANTHRENUS Geof. 



Ovate, convex, dark, covered with scales which are large and triangular 

 in Hrrophular'm, smallei* in mmeorum and clmiger, and very long and 

 narrow in varlus. Head small, a distinct ocfellus, epistoma moderately 

 long and flat, mouth parts entirely protected by the prosternum. Eyes 

 moderately large, prominent, emarginate in scroplmlarice, entire in the rest 

 of our species. Antennae short,- 11-jointed in scrophularice and varius, ter- 

 minated by a 3-jointed club ; 8-jointed in museoram, bearing a 2-jointed 

 club, and 5-jointed in clavigcr, with a large club of one joint. Thorax very 

 convex at base, more than twice as wide as long ; base three or four times 

 as wide as apex, bisinuate, lobed behind in the median line ; lobe acute, 

 covering almost the entire scutellum ; lateral margins slightly expanded, 

 arcuate ; hind angles prominent. Elytra ovate, apices slightly separately 

 rounded. Antennal fossa dividing the anterior part of the lateral margin 

 of thorax. (Fig. G5.) Prosternum short and wide, lobed in front, covering 

 all the mouth parts except the labrum, produced behind into a broad tip, 

 which does not reach much beyond the anterior coxae. ^lesosternum very 

 wide, completely and broadly divided. Mesocoxae very widely separated. 

 Metasternum short, side pieces wide. Posterior coxal plate moderately 

 short, wide, hut not reaching the sides. Femora stout, grf)oyed beneatli
