the Elateridaj of Japan. 2o7 



Densely black, shining, pubescence black on the head and 

 thorax, fulvous on the elytra ; the head rather closely punc- 

 tulatc ; the thorax lightly punctulate, median channel feeble 

 or sometimes absent ; the elytra striate-punctate, interstices 

 little rugose and finely punctulate, yellow, with five black 

 spots, scutellar spot dehiscent behind; two black dorsal spots, 

 somewhat circular in outline, usually partly covering the third 

 interstice and spreading to the eighth, sometimes much 

 smaller; the two apical spots arc sha])cd like the apex ot" an 

 elytron, separated from eacii other and the apex and outside 

 edge usually by the width of two or three interstices. The 

 antennje and legs densely black. 



cJ . Antennaj strongly pectinate, lateral thoracic margins 

 narrowly elevated. 



C. vernalis, llentz, and G. Bosberi, Germ., are similar 

 species to this. 



Ilab. Yuyama, Chiuzenji, and Sapporo. Not rare. 



Corymhites tessellatus, L. 



Cand^ze introduced the name of this species to the Japanese 

 list (Mem. Ac. Belg. 1864, p. 53), and Schonfeldt has the 

 name in his Catalogue ; but in 1873 Cand^ze (Mem. Li^ge, 

 p. 25) says it was given in error. 



Corymhites orientalis^ Cand. 

 Corymbites orientalis, Cand. Elat. Nouv. iv. 1889, p. 114. 



This species is like G. pruinosus ; it measures 15 mill, 

 and the thorax has the hind angles slender and strongly out- 

 turned. 



Ilah. "Japan" {Gandeze). I have an example from 

 Chiuzenji and another from Nikko. 



Corymhites cerosus. 

 Athous cerosus, Lew. Ent. Mouth. Mag. 1870, p. 157. 



This species is somewhat like C. modestus, but it is much 

 narrower, less convex, thoracic angles not straight, yet only 

 feebly turned outwards ; the elytra wholly aeneous ; the 

 antennae entirely black, the legs red and tarsi infuscate. 

 Originally I introduced this in error as an Athous, 



Hob. Kii and Chiuzenji. Three examples.
