Coelioxys deplanata Cresson. — Wawawai, Wash., Aug. 30, 1908 

 (W. M. Mann). Both sexes. 



Coelioxys rtifitarsis Smiih. — Four females, Wawawai, \Vasii , Aug. 

 30 and Sept. 6, 1908 (W. M. Mann). 



Coelioxys innnaculata, n. sp. — Male; Miners, Indiana, July ; collector 

 unknown, but there is a label bearing the number 1525. 



Length a little o\er 10 mm., robusf, black, with rather dull white 

 hair, faintly creamy on up[)er part of head ; eyes pale green, wiih 

 abundant qiii'e long hair; antennre and mandibles entirely black ; tegulce 

 bright apricot colour; femora except the lower side, and tib''a3 and tarsi 

 entirely, bright ferruginous, as also are the tibial spurs ; hair on inner side 

 of basitarsi creamy ; head and thorax with dense, large punctures, those, of 

 vertex larger than those on mesothorax ; lower part of cheeks with a broad 

 bevelled space, which is shining and punctured ; thorax above without the 

 usual white hair patches ; scutellum broadly rounded behind, wuhout any 

 median projection ; lateral teeth thick, not curved ; abdonien shining, but 

 well punctured, the second and third segments with deep transverse con- 

 strictions ; fouith ventral segment with a weak emargination ; sides of 

 fifth segment with very short spines ; sides of sixth with large thick spines; 

 end of sixth with four teeth, the upper ones short, and directed obliquely 

 upwards, the lower large and unusually broad. In Robertsori's table 

 (Trans. Amer. Ent. Soc, XXIX, p. 174), this runs out at 3, because of the 

 red legs, punctured bevelled space, etc. Robertson says of male 

 ociodentata, "disc of abdomen opaque, densely punctured" ; ijiuiiaculata 

 has the abdomen very conspicuously shining, except the sublateral region 

 of the second segment just beyond the sulcus, which is dull and very 

 densely covered with minute punctures, in complete contrast with the 

 corresponding areas on the first and third, and with the sparsely-punctured 

 middle of ihe second.
