with those of P. expallidus, which it greatly resembles, but 

 from which it differs as above, and the comparison there given 

 will apply equally well, except as to the color of the mandibles. 



7. Panurginus ornatipes (Cresson). 



A critical comparison of $ and 9 cotypes of Panurginus 

 nebrasccnsis Crawford with speciments of P ornatipes Cres- 

 son, shows the two to be synonyms, the name ornatipes having 

 priority. Panurginus boylei Ckll. is to be considered a sub- 

 species of P. ornatipes characterized by its wholly dark scape, 

 representing in the mountains of New Mexico the typical form, 

 which ranges in the plains and foothills from Texas to Ne- 

 braska. We have ornatipes from Lincoln, West Point, Broken 

 Bow, and Glen, August 14 to September 18, flying commonly 

 at Grindclia squarrosa and various species of Solidago, includ- 

 ing rigida and inissouricnsis. The species has been found 

 nesting at the Lincoln salt flats. 



8. Panurginus horizontalis n. sp. 



d". Length 8.5 mm. ; clypeus, labrum, mandibles, supraclypeal area 

 and lateral face marks up to level of tip of supraclypeal area deep 

 yellow, its upper level forming a straight horizontal line. Antennae 

 deep black, the front of the scape with a yellow line. Face coarsely 

 punctured, and with a prominent median ridge between the bases 

 of antennae. Mesonotum shiny, coarsely and closely punctured, the 

 base of metathorax with a row of short striae, rest of metathorax 

 dull, finely, closely punctured. Tubercles yellow. Tegulae testaceous. 

 Wings dusky, especially toward their apices, the nervures black, stigma 

 dark brown. Legs black, with all the tarsi and knees, ends of all 

 the tibiae and the front face of anterior femora, deep yellow. Abdomen 

 finely and sparsely punctured, the basal segment subimpunctate medi- 

 ally, the apical margins of segments 1-5 broadly depressed, the de- 

 pressed portions smooth and impunctate. Sides of abdomen fringed 

 with long pale hairs, crossing in a loose fringe at the bases of the 

 depressions on 2-6. Thorax, head and legs with short scattered pale 

 hair, tinged with ochreous on mesonotum and vertex.

This species is related to P. ornatipes (Cresson), but is much 

 larger and differs in the face markings, and other details. It 

 is allied to P. compositarum^Rob., but differs in much greater
