second continuous though emarginate anteriorly in the middle, the 

 emargination produced to right and left in the middle of the fascia, 

 also thrice emarginate on posterior border, remaining fasciae of simi- 

 lar pattern with emarginations reduced on each succeeding segment, 

 apex of ultimate tergite, first sternite except small lateral spots, 

 second except small anterior lateral spots and a median longitudinal 

 spot, broad fasciae on sternites 3-6 narrowed somewhat irregularly in 

 the middle, coxae, trochanters more or less, femora except a stripe 

 above on all pairs and a stripe below on first pair, tibiae, and tarsi 

 except all apical segments, yellow. 



The color on the abdomen is light greenish yellow, while that 

 on the rest of the body is of a deeper shade. Segments 3-5 of the 

 flageilum are reddish below, the apical segment slightly curved, and 

 segments 5-1 1 on the posterior surface are slightly carinate. As on 

 duplicata small pits occur on these carinae, but they are limited to 

 the middle part, whereas on duplicata they extend the full length of 

 the carina. The legs show no special structures, but the apical seg- 

 ment of all tarsi is black. The head, thorax, basal joints of legs, and 

 base of abdomen are covered with moderately dense white pubescence, 

 rather short except on the head, on the vertex of which it assumes a 

 brownish shade. The spine on the second sternite is short, sharp, 

 and directed obliquely backward. Of the three spines which ter- 

 minate the eighth sternite the two lateral are quite short, and the 

 middle one, long and very heavy, bears on its ventral side beyond its 

 middle point distally a fourth very short spme. 



Length. — 18 millimeters.

Male. — Black: Clj^oeus, labrum, mandibles except tips, scape 

 except black line above, spot between insertions of antennae, spot 

 on each side of anterior ocellus, anterior orbits, posterior orbits 

 shortened and narrowed above, small spot on tegulae, narrow line on 

 posterior border of sides of prothorax, small spot on anterior part of 

 mesopleurae low down and extending onto the mesosternum, on one 

 specimen second small spot below insertion of wing, two small spots 

 on metapleurae, legs except a variable amount of black on coxae and 

 trochanters, and abdomen entirely except the basal part of the first 

 segment, Iriglit sulpTiur yellow. 



The pubescence on the head, thorax, and base of abdomen is long, 

 dense and white except on the vertex and the scutum where it is
