THE CANADIAN ENTO.MOLOOIST. 15!) 



This species, which was described from female specimens found in 

 New Jersey and the District of Colambia, has a wide range of distribution. 

 It is not uncommon in north-western Wisconsin at tlie points mentioned, 

 and a few years ago I received, through the kindness of Mr. Hartmann, 

 of Austin, Tex., four female specimens from that locality. 



Sphecodes Latr. 

 Sphecodes Davisii Rob. 



S. Davisii Robertson, Trans. St. Louis Ac. Sc, VII, 319, ^. 



$. — Nine specimens from 7 to 10 mm. in length. In some of these 

 the black on the basal portion of the first abdominal segment takes up 

 nearly the entire segment, leaving only a narrow apical strip of red. 

 Second segment entirely red, third either entirely red or with a black apical 

 margin. 



% . — Head dull, closely punctured. A prominent median ridge from 

 the front ocellus down to the base of the antennas. Mandible with a very 

 distinct tooth. Antennae rather short and thickened towards the tip, black, 

 with a slight trace of reddish underneath. Mesonotum dull, strongly and 

 closely punctured, on the disk, however, as also on the scutellum, where 

 the punctures are farther apart, the surface is somewhat shining. A dis- 

 tinct rim bordering the semicircular enclosure of the metathorax. 

 Enclosure, truncation and sides of the metathorax all coarsely sculptured. 

 Wings not as clear as in the male, and nervures darker. Abdomen red, 

 sometimes with a blackish hue around the tip. First segment shining and 

 impunctate. Remaining segments finely and closely punctured, except on 

 the depressed apical borders of segments 2 to 4. Length, 8 to 10 mm. 



Fourteen 9 specimens from Milwaukee, Racine and Washington 

 Cos. in Wisconsin, and one $ from Ludington, Mason Co., Michigan. 



In size, sculpture and opa(|ae appearance of head and thorax the 

 female of this species, which is a Sphecodes sens, strict., as defined by 

 Robertson, resembles two other species of the Milwaukee region, viz : S. 

 ( Proteraner ) ranunculi Rob., and 6". ( Drepanium) falcifer Patton.

 10 mm. 



d . — Length, 7-8 mm. Head very large, clothed with long white
