NESODIPRION, new genus. 



Type of genus — Lophyrus japonica Marlatt. 



Differs from Biprion Schrank (olim Lophyrus Latreille) in the 

 malar space being nearly wanting; the maxillary palpi five-jointed, 

 the labial palpi three-jointed; the longer spur of the hind tibice equal, 

 or nearly, in length to the basitarsis; and the biramose antennae of 

 the female. The rami are not as long as in the male. Sexes as far 

 as known similar. Larvse feeding on coniferous trees. 



TABLE TO THE SPECIES OF NESODIPRION. 



Species mostly black. 

 Femora entirely black; basal dorsal segment not punctured. Japan. 



japonica (Marlatt). 



Femora at the apex pale; "segmento primo dorsali medio sparsim punctato." 



Hongkong, China biremis (Konow). 



NESODIPRION JAPONICA (Marlatt). 



This species was originally described from Japan. It has been 

 introduced into United States through San Francisco, California — 

 teste a male and female bred from a pine received from Japan, April 

 30, 1902, by Mr. Alex. Craw, San Francisco, California, now in the 

 collection of the U. S. National Museum. 



NESODIPRION BIREMIS (Konow). 



Konow's species may only be a race, but the above differences 

 were noted by comparing japonica with the original description of 

 hiremis. 



Family CIMBICID.E. 



AGENOCIMBEX, newv genus. 



Type of genus — Cimhex maculata Marlatt." (Japan.) 



Rather large robust species with the habitus very like Cimhex; 



labrum small, triangular in outUne, similar to Cimhex; supraclypeal 



suture wanting; malar space large; eyes converging to the clypeus; 



posterior orbits not extending beyond the eyes ; ocelli in a triangle, 



a F. W. Konow (1906) has suggested that Cimhex maculata Marlatt (1898) is a synonym 

 of Gimbex jucunda Mocsary (1896); and the description of Mocsary's species and his 

 figure agree very well with the type of Marlatt's species, but in view of the fact that 

 there is no positive evidence the name maculata is still retained.
