of the funicle are alternately shorter and longer as usual in the tribe, 

 but they are somewhat more widely separated at base than in Ai^atlicn- 

 <:;is ; the first two joints of the club are generally about as long as 

 wide or longer, and seldom at all transverse. The eyes are larger and 

 more coarsely faceted as a rule than in Ai::;at]ieiigis. The prothorax is 

 narrowed anteriorly and generally more or less distinctly angulate at 

 the middle — not nearer the base as in Ai^^af/iengis — and the marginal 

 fovea at the point of angulation is not so marked a character as it is 

 in that genus ; the edge is finely beaded and frequently feebly crenu- 

 late from the angulation to the base ; the disk is evenly convex, be- 

 coming broadly concave along the very finely margined or simple 

 transverse base. The prosternal process is narrow, but in certain 

 species, such as the European tiirgida and cepheuiiioides, becomes 

 wider, more prominent and more strongly margined along the sides — 

 a divergence in the direction of the remarkable genus Sfcnwdca. 

 There seem to be, in fact, several cjuite well defined subgenera among 

 the species of the European fauna having for types such forms as 

 turgidcu with medially lobed thoracic base, stout antennre and 

 broader and more i)rominent ijrosternal process, ceplienuioidcs, with 

 large and broadly truncate prothorax, broad prosternal process, stout 

 antennas and very small eyes, and uitifasciata, which is perfectly con- 

 generic with our species and might be regarded as Afomaria proper. 



The elytra are finely, irregularly punctured, frequently subinflated 

 before the middle, truncate at base and slightly impressed within the 

 humeral callus. The abdominal sutures are straight, the first seg- 

 ment as long as the next two combined and the fourth shorter than 

 the second or third. The legs and tarsi are slender. 



The species before me may be identified as follows : — 



Elytra conspicuously ornamented or l)ico]ored, the lines of demarcation more or less 



wel 1 defined 2 



Elytra unicolorous or imbilously darker toward base 7 



2 — Elytra pale, a dark fascia just before the middle extending from side to side 3 



Elytra black or blackish, the apical third or fourth abruptly, and the basal regions nu- 



bilously pale 4 



Elytra black, abruptly pale in apical two-fifths to half, the base not paler, excepting, 



rarely, the humeral callus 5 



3 — Suboval, strongly convex, piceous, the antenna:, legs and elytra pale luteo-flavate, 

 the latter each with a large, broadly oval oblique blackish spot from basal third 

 at the sides, the two mutually tangent on the suture at the middle ; antenna; 

 slender, half as long as the body ; prothorax strongly, longitudinally convex in 

 profile, moderately transverse, strongly rounded at the sides and narrowed per-
