spots on legs," the lack of a band on tergite i and interrupted 

 bands on 2 and 3, etc. 



Nomada (Holonomada) asteris n. sp. 



$. Length 8 mm. Head, thorax and legs mostly bright red, the black 

 or blackish areas involving only the tips of the mandibles, a small spot 

 behind ocelli, the prosternum, lateral depressions of propleura, anterior 

 mesopleural suture extending behind tubercles and under tegulae and an- 

 terior mesoscutal suture, depressed areas at extreme sides of mesoscutel- 

 lum and metanotum and the suture between, lower metapleural plate, areas 

 on inner side of hind tibiae and basitarsi, and a large cuneate area on 

 mesoscutum which is as wide as the pale portion of the mesoscutellum 

 posteriorly but which rapidly narrows anteriad and does not attain the 

 anterior margin of the sclerite. A spot on each side of collar, the tegulae, 

 elevated portion of mesoscutellum and metanotum, and a narrow line on 

 hind apical margin of posterior trochanters, clear yellowish white. 

 Clypeus, labrum and face strongly and closely but rather finely punctured, 

 " becoming denser on the vertex, mesoscutum punctured like vertex, meso- 

 pleura similarly but more coarsely punctured. Antennae red, the first 

 three joints brightly so, the following joints lightly suffused with dusky, 

 joint 3 slightly but distinctly longer than 4. Tegulae red. Wings dis- 

 tinctly clouded, especially on apical margin, nervures fuscous, stigma 

 edged with paler, basal nervure interstitial with transverso-medial nervure. 

 Abdomen dark red, strongly, densely and rather coarsely punctured, apical 

 margins of tergites 2-4 distinctly reflexed, apical margins of tergites 1-3 

 and whole of tergites 4-6 deeply suffused with fuscous, tergite i basally 

 wholly clear red, 2 with large suboval yellowish white lateral spots, 3 

 and 4 with similar but slightly smaller spots, venter clear red. Body almost 

 glabrous, the mesonotum and legs with exceedingly sparse and short pale 

 hairs, the inner side of hind basitarsi with dense short grayish white 

 hairs, and the sides of abdominal tergites 4-6 with sparse long pale bristles 

 intermixed with tufts of curved black bristles on 6, 5 with an apical band 

 of snowy white tomentum. Pygidial area acutely rounded at tip. 



Type. — Manhattan. Kansas, September 19, 1908, on Aster 

 paniciilatiis (O. A. Stevens, No. 1203), 5- 



A very distinct species. Apparently allied to A'', gutierresiae 

 Ckll., but has joint 3 of antennae less than 4 + 5) and lacks the 

 creamy marks on the sides of face, base of mandibles, mesopleura, 

 axillae, hind tibial apices, and first abdominal tergite, and has 

 the bands on tergites 2-4 reduced to lateral spots. A^. { Nomada) 

 adducta Cresson is somewhat related, and seems in some respects 

 more or less intermediate between Holonomada and Nomada
