apieally tlio pimetiires are more shallow and quite remote, the lateral 

 margins bluntly tuberculate, bisinnate, rather strongly constricted at 

 second sogiiuMit, the ventral ridge strong and raised into a sharp median 

 prominence. Second segment very shallowly and sparsely punctured. 

 Last dorsal segment shagreened basally, with a few very large punct- 

 ures on apical half, with the tip rounded and apparently lacking the 

 usual tufts of golden hairs at the apical angles. 



This is nearest to ocellatus, but that species has pale fuliginous 

 wings. Viereckii was collected in Orinsby county, Nevada. 

 4043 Odontophotopsis ocellatus n. sp. 



Length 9 mrn. Castaneous with the legs nearly concolorons and with 

 principally golden pubescence. Head subtriangular as viewed from the 

 side; as viewed from above, broadly semicircularly rounded behind. 

 Vertex shallowly, sparsely punctate, and with very few brownish hairs. 

 Occiput and genae frirged with yellowish hairs, the gular region nearly 

 nude. A black dot on anterior margin of each ocellus; the two posterior 

 ocelli much nearer to each other than to the eyes. Scape honey yellow, 

 coarsely punctured, and with short golden pubescence; flagelhun 

 testaceous, slightly darker at tips, and covered with fine short white 

 down, the first article nearly as long as the second. Malar space clearly 

 defined, equal to widfi of scape. Mandibles with sparse golden hairs, 

 the tooth subtending cmargination on lower border very large, as broad 

 from tip to bottom of emargination as the remaining width of mandible; 

 tips black and bidentate, but also with a subobsolete median tooth. 



Thorapc with the pubescence golden above and in front, white below 

 and behind. Prothorax apparently without plumose hairs. Mesonotuni 

 shining, very sparsely and very shallowly punctured; disc with a median 

 groove; the lateral pairs of grooves in place but the outer ones obsolete 

 except near the hind inargin. Metanotum coarsely reticulated, the meshes 

 very large and mostly subpentangular, two in the middle anteriorly, of 

 the width of the others but as long as four or five, in front of these 

 two side by side are thrown together in one large space; laterally the 

 meshes are siraller and more irregular. Mesosternum evenly coarsely 

 reticulato-punctate, the median teeth comparatively large and long. Legs 

 slightly paler than the body, extreme tips of mid tarsi slightly darkened. 

 Tegulae slightly paler than body. 



Wings evenly infuscated throughout; the veins are honey yellow, the 

 stigma darker; apex of narginal cell obtusely pointed; the first re- 

 current nervure entering second submarginal cell slightly before the 

 middle of its lower margin; tvansverso-median nervure joining the 

 externo-median considerably in front of the basal. 



Abdon:en shining and clothed with long golden hairs, the hairs below 

 very sparse, shorter, appressed and on venter of first segment and apex 

 of second more whitish; second and following segments sparsely punct- 

 ate; the usual "felt lines" present on the second segment, and on its 

 apical margin a row of white plmnose hairs; no other segments have 

 sui'h rows of plumose hairs, but a few golden hairs back of apical
