Longicorn Coleoptera of Japan. 151 



Fam. Prionidae. 



Prionus insularis, Motschulsky. 



Priomis instdaris, Motschulsky, Etudes Entom. 1857, p. 36, J ; id. 1861, 



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

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

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



Japan, common ; also Xorth 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. 



^gosoma simcuin, White. j. 

 JEgosoma sijiicum, White, Cat. Long. Col. Brit. Mus. p. SO, $ . 



Many examples ; on fir trees. 



White only knew the female, which resembles the same sex 

 of j^. scahricorne. 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. Cerambycidae. 

 Section A. Eyes coarsely faceted. Hahits nocturnal. 

 Spondylis buprestoides, Linn. 

 Spmdylis bup-estmdes, Linn. Syst. Nat. xii. 2. p. 621, 

 Also found in N. China. 



Criocephalus rustic^iSy Linn. 

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

 ent. Zeit. vii. p. 107. 



Maiyasan ; ranning over fir trees at night. 

 Japanese examples have punctured elytra and sutural apices 

 briefly spinose, as in German specimens. 



Xystrocera globosa, Oliv. 

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

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



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



Fabricius erroneously cited Brazil as the locality of his 

 Stenocorus vittatus, which is evidently the same as Xystrocera 

 glohosa.
