cuneata flies during April, May and the early part of June, its flight 

 being coincident with that of bella. My latest date is June 5, Edge 

 Hill, Pa. The localities represented are: Edge Hill, Pa., ? (Viereck); 

 Ashbourne, Pa., d^ (Viereck); Montgomery county, Pa., 9 (Viereck); 

 Lehigh Gap, Pa., ? (Viereck); New York State (Baker collection, 9 , 

 No. 1,868; cJ', No. 2,168) ; Indiana (Baker collection, ?, Nos. 2,002 

 and 2,040; d^, No. 1,876); Illinois, d^ (Robertson; sent years ago as 

 maculata); Lincoln, Neb. (Bruner) ; Cedar Bluffs, Neb. (Bruner). 

 Six males from Polk county. Wis., and one from New York State, 

 all from the Baker collection, represent forms differing from N. 

 cuneata, as is indicated in the table given above. They appear to 

 constitute two geographical races, perhaps species; but as they are 

 reddened by cyanide, and I have no females which belong to them, I 

 leave them without names. 



Nomada albofasciata. Smith. 



I have before me one male from Polk county, Wis. (Baker), and one 

 from New York State (Baker coh., 2,168), both from the National 

 Museum. The species was described from Canada. It is separable 

 from cuneata by the bands of the abdomen being creamy-white instead 

 of yellow, but it is extremely closely allied. When the abdomen is 

 retracted, the bands on the third and following segments become partly 

 or wholly hidden. The length of the insect is 6^ to 7 mm. 



Nomada louisianae, sp. n. 



9. — Length 8 mm.; dark red; antennse entirely red, third joint 

 nearly as long as fourth; a short keel between antennae; some black 

 between ocelli and between antennae; mesothorax with a single black 

 band; metathorax with a black diamond; apical margin of wings 

 strongly dusky; stigma dark reddish-brown, nervures fuscous; abdo- 

 men without spots or bands of yellow; four black spots at sides of base 

 of first segment; p3^gidium shovel-shaped. Known from N. cuneata 

 by its narrower, more cylindrical abdomen, and narrower face. 



Hah. — Louisiana (Baker coll., No. 2,420), one in National Museum. 

 With regard to the Bakerian numbers, it is well to state that they repre- 

 sent particular lots of specimens, captured at the same place, but not 

 particular species. Hence different species often bear the same 

 number. 

 Nomada carolinae, sp. n. 



9 . — Length about 7^ mm, ; red ; region above antennae, region about 

 ocelli, broad band on mesothorax, broad band on metathorax, much of 

 prothorax, and region between wings and middle and hind coxae, all
