Odontophotopsis acinaeiis n. sp. 



Leiisth. 'S ) 9 mm. — Head. — Polished, punctures sparse and fine, median im- 

 pressed line on the front distinct in greater part. Distance between posterior 

 ocelli about twice that between them and the anterior ocellus; distance between 

 posterior ocelli equal to or a little less than that between them and nearest eye 

 margin. Lower margin of the eyes almost contiguous with the insertion of the. 

 mandibles. Mandibles elbowed, slender beyond the bend, not deeply emargiuate 

 on the lower margin whicb is merely undulate, without a strong tooth. 



Thorax. — Prothorax rugose. Punctures of dorsulum separated, almost contig- 

 uous; inL;ermost furrows strong, lateral furrows faint, starting about one-third 

 the distance from the anterior margin. Scutellum closely rugose; postscutellum 

 indistinctly sculptured, rugulose. Propleura rugose, in part simply roughened ; 

 mesopleura with shallow punctures on depressed part, bulged part with shallow 

 contiguous punctures, posterior border smooth and polished. Area not symmet- 

 rical, rather oblong. Meshes of the reticulation, on metathorax, large, the raised 

 lines defining them, not strong. A short abcissa on the radial nervure the only 

 trace of a second cubital cell ontline, first submarginal cell like in exogyriis; sec- 

 ond recurrent entirely, sul)discoidal almost, obliterated. Transverse median ner- 

 vure originating a little beyond the basal nervure. 



Abdomen. — Petiole with punctures not sharply defined, close together and shal- 

 low. Second segment very finely, sparsely jjunctured. Felt line about one-half 

 length of segment, on ventral segment a little shorter. Subtle area hidden. 



Color. — Pubescence white, dorsally tinted with yellowish. Tegument pale tes- 

 taceous, between ocelli almost black, antennae paler than the body, legs very 

 much paler. Stigma testaceous, uervures very pale.
