By Alev. D. MacGillivray. 
The following new species constitute a part of a collection

received from Professor A. L. Lovett of the Oregon Agricultural 
College, Corvallis, Oregon. 
Macremphytus lovetti sp. nov. 
Female. Body black with the four distal segments of the 
antennae, the labrum, the tegulae, the protibiae and protarsi, the 
mesotibiae and mesotarsi, the metatrochanters, and the metatarsi, 
white; antennae with the three proximal segments and part of 
the fourth, the head except the clypeal suture and the postocellar 
area, the thorax except the margins of the lobes of the 
mesonotum and the mesoscutellum, the proximal two-thirds 
of the metatibiae, and the abdomen except the saw guides, 
rufous; antennae flattened, first and second segments of the 
flagellum subequal; clypeus roundly emarginate; ocellar basin 
small, irregular; saw-guides with the dorsal margin straight, 
the ventral convex, obliquely convexly rounded at apex; 
wings yellowish, costa reddish, proximal half of stigma white, 
veins black. Length, 14 mm. 
Habitat: — Rock Creek, Corvallis, Oregon; A. L. Lovett’ 
collector. This beautiful large species is similar to varianus 
Norton, but easily separated by the difference in color. It 
gives me pleasure to name this species after its collector. Pro- 
fessor A. L. Lovett.

Male. Body black with the labrum, tegulse, coxae, and 
trochanters, white; the legs beyond the trochanters, abdomi-
