shortening of joint 4. Wings clear except for the darkened apical 

 margin, nervures reddish, stigma bright ferruginous, basal nervure slightly 

 but distinctly basad of transverso-medial nervure, the second submarginal 

 cell broad and receiving the first recurrent nervure v^rell beyond its middle. 

 Legs red, spots on coxae and trochanters in front, apices of all the femora 

 and a wash on anterior face of front femora, apices of all the tibiae 

 and a narrow line down anterior face of front femora, apices of all the 

 tibiae and a narrow line down anterior face of middle tibiae, broader 

 lines down both faces of hind tibiae and whole of front tibiae except a 

 red spot behind, together with the bases of the basitarsi, all yellow; the 

 coxae behind, last four trochanters behind, and more or less well-defined 

 lines in the centers of the red areas on femora and tibiae behind, black or 

 blackish. Abdomen yellow, the base of tergite I blackish with a wavy 

 posterior margin, the apical margins of tergites 1-6 reddish, the extreme 

 bases of tergites 4 and 5 black if the segments are fully exserted, the apex 

 reddish and slightly notched apically. Venter yellow, the apical margins 

 of sternites 1-5 narrowly reddish, at least laterally, and sternite 6 with 

 reddish basal spots. 



Type. — Laramie, Wyoming, June 10, 1893 (collector un- 

 known), (^. 



Paratypc. — Type lot, i J*. 



The paratype lacks the head and abdomen but is otherwise 

 identical with the type. In Cockerell's table of Rocky mountain 

 species this runs to A'', luteopicta Ckll., and further tallies quite 

 closely with the description of that species, but apparently differs 

 in larger size, in having a, yellow line behind eyes and consider- 

 ably more yellow on the legs, especially on the tibiae and basitarsi, 

 in having the hair of the vertex and thorax above tinged with 

 ochreous, the wings clearer and with a different venation (second 

 submarginal cell broad and basal nervure basad of transverso- 

 medial), etc.; in fact, if the males of luteopicta belong with the 

 female associated with it by Cockerell, which seems doubtful, it 

 is a Noniada sens. str. N. laramiensis is, however, very closely 

 related to A^ elrodi J*, but is separable by the comparatively 

 shorter fourth antennal joint, the much greater amount of yellow 

 on the legs, the more copious pubescence on the head and thorax, 

 especially on the face in front, the clear yellow tegulae and larger 

 pleural spot, etc. From the male of A'', alpha, just described, it 

 differs in much the same characters.
