has the propodeum black and is referable to convolvuli. Typical 

 vierecki is known only from New Mexico and Chihuahua. 

 Although in the small series available there is no intergradation 

 shown, this case is with little doubt a parallel one with modesta 

 and vegana, articulata and dacotana, etc. From A^. heiligbrodtii 

 Cresson, convolvuli differs in slightly smaller size, more separated 

 punctures of the mesoscutum, and wholly red antennae in the 

 female, while the male, if the described male really belongs with 

 the female, may be separated by the complete abdominal bands on 

 tergites 1-4, larger pleural spot and bivittate venter. From the 

 other small species of the subgenus Micronomada the cream 

 colored ornaments, at least on the abdomen, the unspotted propo- 

 deum and banded venter are diagnostic.

A female collected in Dewey Lake Township, Cherry county, 

 June 18, 1902, by R. H. Wolcott is the only known record for the 

 state. Though the specimen is reddened by cyanide the macula- 

 tions appear to be considerably paler than is indicated in Cresson's 

 description, but otherwise the specimen agrees. 



SPECIES FROM OUTSIDE NEBRASKA 



Nomada (Micronomada) aureopilosa n. sp. 



$. Length 9 mm. Stoutly built, black. Lower half of clypeus, lateral 

 face marks extending considerably inward along clypeal suture but other- 

 wise narrowly confined to orbital margin, line along posterior orbits, 

 malar space, labrum, mandibles, antennae, collar, tubercles, tegulae, 

 axillae, mesoscutellum, metanotum and legs, except for the black posterior 

 side of the coxae, posterior femora and a triangular spot on posterior 

 tibiae, red. Red stains forming a suprategular line, irregular patch on 

 mesopleura and pectus between middle legs reddish. Mesoscutum closely, 

 rather coarsely but not very strongly punctured. Head and thorax, 

 especially mesopleura, rather copiously provided with short, bright golden
