margin; apical angles with tufts of sliort golden hairs; the slendei' 

 brown styles are here extended to half the length of this segment. 



This species is very clearly distinguished by the sculpturing, and dis- 

 position of- the jnibeseenee. It was collected at Claremont, California. 

 4041 Odontophotopsis mellicornis n. sp. 



Length 11 mm. Castaneous, with white pubescence. Head subtri- 

 angular as viewed from the side, sloping behind the eyes, not at ali 

 quadrate; viewed from above it is broadly semicircularly rounded 

 behind. Vertex shallcwly, irregularly, and sparsely punctured, and with 

 rather short white hairs; occiput and genae fringed with much longer 

 hairs, those on the gular region also long and mostly plumose. Ocelli 

 with the two posterior nearer to each other than to the eyes; space 

 between the ocelli black. Antennae honey yellow, the scape punctured 

 and white pubescent, the first article of flagellum not as long as the se- 

 cond. Mandibles whitish pubescent, and with a blur.r touth sul>tending 

 an emargination on the lower border; the tips are 'nlnck and bidentato. 

 Maxillary palpi with articles II, III, and V of equal length, IV a little 

 shorter. 



Tharax rather thickly white pubescent, the hairs thi(dccst and longest 

 on prothorax, mesothorax, and scutellum, and with rows of short 

 plumose hairs along the sutures of the prothorax. Mesonotum shining 

 and distinctly but rather sparsely punctured, and with two fine long- 

 itudinal grooves on either side. Scutellum opaque and finely rugose. 

 Metanotum shining, coarsely reticulated, the meshes larger and sub- 

 equal medially, smaller at the sides. Mesosternum punctured, sparsely 

 in front, rugosely behind, and armed with two short teeth near the 

 median line. 



Legs honey yellow, apical two-thirds of mid and hind femora black- 

 ish, the mid and hind tarsi similarly though not so deeply blackened. 

 Tegulae pale honey yellow. Wings nearly hyaline except for a small 

 cloud in the marginal cell next the stigma; the veins are honey yellow 

 and the stigma pale brown; apex of marginal cell obtusely pointed; 

 the first recurrent nervure enters the second submarginal cell at the mid- 

 dle of its lower margin. 



Abdomen mostly shining and with numerous long white hairs equally 

 numerous above and below, and specially dense on the apical half, 

 near the margins of the segments; hind margin of third and succeeding 

 segments dark brown; first abdominal segment long trapezoidal as 

 viewed from above, its length less than twice the breadth at base, 

 strongly constricted at its juncture with the second, below with a strong, 

 rough, evenly curved median ridge; at base and apex of first segment" 

 and at apices of second and third segments, passing around the 

 abdomen, are fringes of short plvimose hairs, the fringe on second 

 segment thickest and most conspicuous; the second segment is very 

 sparsely punctured; the pubescence on the apical segments has a yellow- 

 ish cast; last dorsal segment punctured near tlie basal angles, and with
