separated from co?nbinata. In none of my specimens do I find the polished 

 frontal stripe narrowed anteriorly, and yet in some the brown spots form 

 very distinct double bands running across the wing. I find the ante- 

 penultimate band to run as frequently before as over the posterior trans- 

 verse vein. Again, in those specimens with the double-band arrangement 

 of the brown spots on the wings, I find the tibije in more than two-thirds 

 not darker than the femora. In some of the specimens there is only a 

 feeble attempt at double bands ;* even in single specimens I find both 

 double and single bands, showing an unusual degree of variation for 

 species of this genus. 



Tet. pubescens, sp.nov. i ^ ^ . Third joint of the antennae shorter than 

 the second, excised, bristle white pubescent, wings reticulated, with nar- 

 row costal border, posterior transverse vein but slightly curved and nearly 

 perpendicular, tips of tarsi black. Long. corp. 7 mm. Long. al. 6.5 mm. 



Yellowish-brown, somewhat tinged with reddish. Front yellow, with 

 the middle stripe broad, excavated and polished, widening somewhat 

 anteriorly ; on each side near the orbit is a small black dot, and more 

 anteriorly a second larger one between the antennse and the anterior 

 corner of the orbit. Antennse reddish yellow, with the third joint shorter 

 than the second, distinctly excised above and somewhat pointed ; the 

 second joint very broad, the upper border thickly studded with stout 

 hairs, the under border with finer hairs. Antennal bristle slightly yellow- 

 ish at the base and covered with a whitish pubescence. Face with w^hite 

 reflection and considerably receding. Dorsum of the thorax with two 

 stripes dusted with white and bordered with brownish streaks, enclosing a 

 rather narrow median yellowish stripe ; lateral borders dusted with yel- 

 lowish. Superior part of the pleurae with a brownish-red longitudinal 

 stripe extending to beneath the halteres. Scutellum somewhat lighter than 

 the thorax. Abdomen yellowish-brown, with narrow brownish median 

 stripe interrupted at the incisures. Legs yellowish ; tarsi tipped with 

 black. Surface of the wnngs yellowish, with the margin of the costal 

 border black, extending from the stigma to the fourth longitudinal vein. 

 There are five or six small clear spots on the anterior margin of the second 

 longitudinal vein ; the remainder of the reticulation similar to, but coarser 

 and less distinct than in saratogeiisis, consisting of narrow longitudinal 

 stripes bordered by small transverse spots, arranged for the greater part in 

 pairs. The anterior transverse vein is near the middle of the discal cell ;
