Colorado; Kansas (Snow); Cypress Mills, Texas (Ashmead); Illi- 

 nois. Resembles texana but differs by having the dorsulum and mid- 

 dle-segment above maculated and by clearer wings. The £ is as 

 follows : $ . — - Inner and posterior orbits, clypeus, labrum, spot 

 between antennae, and another before the anterior ocellus, scape be- 

 neath, mandibles except apex, prothorax particularly on the sides, 

 large irregular spot on mesopleurse and another on the metapleurse and 

 sides of middle-segment, two short parallel spots on dorsulum ante- 

 riorly, a line at the sides near the tegulre, sometimes a lateral spot 

 on the scutellum, spot on fore and medial coxa?, femora except at 

 base and a line on hind pair, tibise except a line on anterior pair, 

 tarsi except claws, two spots, widely separated on first dorsal seg- 

 ment, broader spots, narrowly separated and sometimes each in- 

 cluding a black spot on second, strongly sinuated, narrowly separ- 

 ated marks on segments 3-6, spot on seventh, large lateral spots on 

 second ventral sometimes united into a band, and smaller spots on the 

 remaining segments, yellow; flagellum yellowish testaceous beneath; 

 head, thorax, and abdomen with cinereous pubescence, short and 

 rather sparse on abdomen; wings hyaline, nervures pale testaceous; 

 joints 6-8, or 9, of flagellum dentate beneath ; middle femora 

 beneath serrate; middle segment strongly impressed down the 

 middle; second ventral segment with a large, strongly curved tooth 

 or hook ; sixth ventral with a strong tooth ; stipes of genitalia as in 

 fig. 4, PI. XIV. Length, 13 mm. The three males before me 

 have no yellow on the upper surface of middle segment and a female 

 from the same locality has but a slight trace of yellow on the part 

 mentioned.
