Longicorn Coleoptera of Japan. 151 



Fam. Prionidae. 



Prionus msularis, Motschulsky. 



Prionus msularis, Motschulsky, Etudes Entom. 1857, p. 36, 2 ; id. 1861, 



p. 21, S; Solsky, Horse Soc. Ent. Ross. t. vii. 

 P. tetanicus, Pascoe, Ann. N. H. xix. p. 412 (1867). 

 P.fossatus, Pasc. Trans. Ent. Soc. 2nd ser. iv. p. 90 (1857) ? 



Japan, common ; also North China. 



I see no difference between Japanese specimens and others 

 from Northern China, whence Pascoe described his P. fossatus ; 

 his description, however, does not precisely agree with the 

 insect, especially as regards punctation, and I cite the syno- 

 nymy with doubt. 



JEgosoma sinwiim, White. 

 JEyosoma sinicum, White, Cat. Long. Col. Brit. Mus. p. 30, $ . 



Many examples ; on fir trees. 



White only knew the female, which resembles the same sex 

 of 2E. scabricorne. The male is much more different from the 

 corresponding sex of that species, having much shorter and 

 thicker antenna?, with the scape shorter and more cubical. 

 The thorax differs in shape, being gradually widened from 

 apex to base, at which latter it is nearly equal in width to the 

 elytra. 



Fam. Cerambycidse. 



Section A. Eyes coarsely faceted. Habits nocturnal. 



Spondylis buprestoides, Linn. 

 Spondylis buprestoides, Linn. Syst. Nat. xii. 2. p. 621. 

 Also found in N. China. 



Criocephalus rusticus, Linn. 



Criocephalus rusticus, Linn. Syst. Nat. xii. 2. p. 634 ; Kraatz, Berl. 

 ent. Zeit. vii. p. 107. 



Maiyasan ; running over fir trees at night. 

 Japanese examples have punctured elytra and sutural apices 

 briefly spinose, as in German specimens. 



Xystrocera globosa, Oliv. 

 Xystrocera globosa, Oliv. Entom. no. 66. p. 27, t. 12. f. 81. 

 Stenoconis vittatus, Fab. Syst. El. ii. p. 309. 



Many examples, agreeing with others from Cambodia, &c. 



Fabricius erroneously cited Brazil as the locality of his 

 Stenoconis vittatus, which is evidently the same as Xystrocera 

 globosa.
