CERAMBYCID.E 291 



2 Prothorax shorter than wide, rounded at the sides and with large 

 callous spaces; upper surface irregularly pubescent; prosternum 

 vertical behind; femora bispinose at apex; elytra strongly bispinose 

 at tip. [Type Cerambyx irroratus Linn.] Elaphidion 



Prothorax elongate and cylindrical; upper surface subglabrous but having 

 long erect flying hairs; prosternum not vertical, sloping gradually 

 upward behind; body very slender, linear and moderately shining, 

 punctate; elytra sinuato-truncate but not spinose at apex; antennae 

 somewhat flattened distally. [Type Elaphidion tenue Lee.]. 



Anepsyra 



3 Prothorax elongate, nearly or quite cylindric; vestiture as a rule 

 uniform, subdecumbent and more or less scanty; body more or less 

 slender, the elytra very elongate, parallel or very nearly and recti- 

 linear at the sides, very moderately spinulose at tip as a rule 4 



Prothorax never elongate, generally distinctly wider than long, with 

 rounded or subangular sides; body frequently very stout, though 

 sometimes notably slender, the elytra less parallel and with less 

 rectilinear sides, the decumbent vestiture generally variegated with 

 more condensed irregular patches 6 



4 Prothorax feebly biconstricted and very feebly and remotely punc- 

 tate, shining as in many Ibidiones; body extremely slender, notably 

 shining, the met-episterna very narrow and parallel; antennae very 

 slender and filiform, not carinate at any part, the outer joints not 

 at all flattened, the spines very small, not visible beyond the fourth 

 joint; elytra deeply sinuate and moderately bispinose at apex; 

 legs and tarsi very slender, the femora not spinose. [Type Steno- 

 coms unicolor Rand.] Pseudibidion 



Prothorax not biconstricted, always strongly and closely sculptured;, 

 femora not or very feebly bispinose at tip 5 



5 Body moderate in size, slightly less slender than in Pseudibidion; 

 antennae slender, with joints three to five or six carinulate, sometimes 

 strongly but generally rather obsoletely, the outer joints but very 

 slightly flattened, not or but slightly carinate; pubescence uniform 

 and rather sparse as a rule; elytra narrowly sinuate and feebly 

 bidentate at apex in typical forms. [Type Elaphidion siibpubescens 

 Lee.] Aneflomorpha 



Body much larger, the antennae long and broader, strongly flattened, the 

 outer joints distinctly carinate, the subbasal without trace of the 

 Ibidion-like carina; sculpture of the upper surface coarser and more 

 conspicuous in the typical forms, the elytral tips emarginate and 

 moderately bispinose. [Type Elaphidion protensum Lee.]. . Aneflus 



6 Body large and notably stout, with great sexual differences in the 

 form and sculpture of the prothorax; antennae more or less flattened 

 apically, with notably developed dense sensitive punctulation along 

 the concave lower part of the joints; spines moderate; met-episterna 

 broad, distinctly narrowed antero-posteriorly. [Type Cerambyx 

 atomarius Drury] Romaleum 



Body smaller, moderate to small in size and always much less stout in 

 form, sometimes very slender; sexual differences in the prothorax 

 frequently distinct in sculpture but less marked than in Romaleum;
