194 Prof. J. C. Sehjodte on the Classification of Cerainbyces, 



Pcecilosoma. — Many small foveae on the last joints. 



Ctenoscelis. — A small oval fovea at the end of the third, fourth, 

 and fifth joints ; the following joints with a couple of foveae at 

 the apex and one at the base, the foveae on the last joints by 

 degrees combining into irregular longitudinal canals. 



Solenoptera. — A small fovea at the apex of the third joint and 

 those next following ; a greater number on the middle joint, and 

 on the last two joints longitudinal rows of pores. 



^Egosoma. — A small poriferous spot at the apex of the third joint; 

 a larger one at the apex of the fourth ; on the fifth the same, and 

 an additional spot at the base ; on the sixth and following joints 

 the spots at the base and apex confluent, the last joints showing 

 a continuous poriferous surface. 



Aueacopus. — A group of numerous small spots at the apex of 

 the third joint ; on the following ones the number of spots in- 

 creases, so that the terminal end of the antenna is covered with 

 innumerable oblong spots, as if punctated. 



Mallodon. — On the third joint a number of oblong foveolae, which 

 gradually increase in number and length on the following joints, 

 and finally on the last joints combine with one another so as to 

 form partly irregular grooves, partly a net with long meshes. 



Acanthinodera A multitude of oblong foveae on the third 



and next following joints, increasing in number on the middle 

 joints, the last being entirely covered with narrow poriferous 

 furrows. 



Macrotoma. — On the third, fourth, and fifth joints a small pori- 

 ferous spot at the apex ; on the sixth a small spot at the base 

 and a more elongated one at the apex ; the seventh the same, but 

 with an additional small spot at the apex ; on the eighth the spots 

 at the two extremities begin to unite, and the following joints 

 show two or three long poriferous canals. 



Orthosoma. — All the joints entirely occupied by long poriferous 

 grooves. 



Naosoma. — Two small spots at the apex of the third joint ; on the 

 fourth, two at the base and two others at the apex ; on the fol- 

 lowing joints the spots more or less confluent ; the last joints en- 

 tirely covered with poriferous grooves. 



Enoplocerus. — Two small spots separated by a ridge at the apex 

 of the third joint ; and on all the following joints two at the base 

 and two at the top. 



Ergates. — A small spot at the top of the third joint ; on the fourth, 

 one at the base and two (a larger and a smaller one) at the apex; 

 on each of the following joints two at the base and two at the 

 top. 



Caelipogon. — A small spot near the apex of the third joint ; two 

 small ones at the apex of each of the following ; on the last joints 

 also very small spots at the base ; on the two last of all, two elon- 

 gated spots. 



Parandra. — Each joint with two deep, oval, poriferous foveee sepa- 

 rated by a sharp longitudinal ridge.
