THE GENUS ATEUCHtJS. 219 



B. Elytra attenuated towards apex ; intermediate 

 tibia3 furnished with an articulated spur at 

 apex ; the four posterior tibife are trun- 

 cated at apex ; body more or less cordi- 

 form ; lateral margins of elytra with a 

 strong reflexed longitudinal carina or ridge. 

 i. Abdomen strongly cordate, with the apex 

 obtuse, greatly attenuated towards apex, 

 more convex ; thorax more convex, trans- 

 versely compressed, giving it a more trun- 

 cated appearance in front ; head not per- 

 ceptibly elongated . . . Actinophonis, Creutz. 

 ii. Abdomen very slightly cordate, very slightly 

 if at all convex ; thorax simple, slightly 

 convex ; head perceptibly elongated in 

 front ; anterior tibiae very much elongated, 

 straight, 4-dentate ; hind tarsi verticillated ; 

 body flattened ; legs very hairy . Parateiichus, Shipp. 



Sebasteos, WesUv. 

 Trans. Ent. Soc. iv. 1842, p. 2. 

 Head distinctly elongated, free, and dilated at sides ; clypeus 

 with three deflexed teeth on the under side, one at the apex of 

 the central indentation on the under side, and one at each of the 

 apices of the two centre teeth ; fore tibiae with a centre spur on 

 the inner margin, curved inwards at apex ; four hind tibife 

 slightly truncated, with a long curved spur springing from the 

 inner margin ; a very large and deep cicatrice on each side of 

 the lateral margins of the thorax, just above the centres ; the 

 anterior angles terminated in two small obtuse teeth ; hind tarsi 

 pyriform, jointed ; apical margin of the mentum curved, not 

 sinuated as in Ateiichus.

Prof. Westwood described this genus in 1842 with galenus 

 (anew species) as his type. Bohemann (Ins. Caffr. ii. 1857) uses 

 the name to denote rmticus, fiDiebris, cicicatricosus {boJicmanni, 

 Har.) ; whilst paradoxus {galenus, Westw.) is placed by him in a 

 subgenus Actinophorus. Erichson, evidently not comprehending 

 the generic characters, places intricatus, morbillosus, and laicus 

 as belonging to it.
