the pit; antennal furrows nearly continuous; postocellar furrow want-

 est at base, tapering; sheath more sharply pointed than the sides 

 of the ninth segment; cerci robust. Metallic blue; antennae and four 

 anterior legs black ; abdomen and posterior legs beyond the trochan- 

 ters, except the brownish apex of tibiae and their tarsi, reddish-yellow.

Family DIPRIONID^ [olim Lophyrid^]. 



Genus DIPRION Schrank. 

 =Lophyrus Latreille (not Poli). , 



The generic name LopJiyrus was used by Poli in Mollusca in 1791. 

 Diprion Schrank was described the same year as Lophyrus Latreille 

 (1802), but with 93 pages priority so should be used in place of 

 Lophyrus Latreille (not Poli) . 



Type. — Tenthredo pint Linnaeus. 



DIPRION NIPPONICA, new species. 



Differs from D. variegata (Hartig)," its nearest ally, in its larger size, 

 distinct postocellar furrow, not impressed and more coarsely punc- 

 tured postocellar area, coarsely punctured clypeus, the deeply arcuate 

 false clypeal margm, and black legs. 



Female, — Length 8.5 mm. Clypeus subdepressed apically, the 

 apical part punctured, similar to the upper, anterior margin arcuately 

 emarginate, the false margin more deeply emarginate; antennae 20 

 jointed, the third joint much longer than the fourth, of the type of 

 pini; antennal foveae well defined, not very large; middle fovea 

 rather distinct, nearly circular in outline; ocelli in a curved line, 

 anterior one not in a basin; postocellar area not sharply defined lat- 

 erally, not impressed, punctured like the rest of vertex and front; 

 postocellar furrow sharply defined, but little longer than the post- 

 ocellar line; postocellar line shorter than the ocellorbital line, and 

 hardly one-fourth longer than the ocelloccipital line; dorsulum 

 coarsely punctured, with rather large punctures; metanotum punc- 

 tured all over; inner calcarium of posterior tibiae simple; claws with 

 an erect median tooth; basal plate with poorly defined punctures; 

 venter with distinct punctures; last ventral plate produced in the 



oD. variegata Hartig is said to be a synonym of D . frutetorum (Fabricius), but the 

 two are easily separated by color, and until more evidence has been obtained they 

 should be kept separate.
