DESCRIPTION OF THE SPECIES. 307 



scutellum. Abdomen gray, with four rows of black spots. The 

 spots of both intermediate rows are comparatively large rectan- 

 gular triangles, one cathetus of. which lies along the posterior mar- 

 gin of the segment, the other is parallel to the longitudinal axis 

 of the abdomen ; thus between both rows of spots, only a narrow 

 gray intermediate line remains visible ; the spots of the outer 

 rows lie upon the lateral margins and also occupy the whole length 

 of the segments, forming broad, uninterrupted lateral stripes. 

 The whitish pile upon the abdomen is rather stubble-shaped; the 

 comparatively long and strong bristles upon the posterior margin 

 of the last segment are black. Venter somewhat dirty brick-red, 

 gradually becoming blackish towards the lateral margins. Ovi- 

 positor flattened, broadly truncate at the end, shining black on 

 the surface ; the under side bright yellowish-red, with a black 

 tip. Feet of an impure yellowish, the posterior femora on the 

 under side with two well-defined blackish spots, and near the tip 

 with a faded blackish spot. Wings very broad, of the same 

 rounded elliptical shape as in T. euryptera. The black, guttate 

 reticulation covers the whole wing to the extreme basis ; along 

 the whole posterior margin as far as the apex, there is a row of 

 hyaline drops of middle size, separated by considerable intervals ; 

 beyond the apex, along the anterior margin, these drops become 

 larger, their intervals growing smaller; in the marginal and 

 costal cells they coalesce with a little drop placed behind them, 

 so that, in these cells, the reticulation emits something like little 

 rays, running towards the anterior margin ; the stigma, upon the 

 extreme basis, has a whitish crossline and includes a hyaline 

 drop at the end ; upon the whole inner side of the surface of the 

 wing the black color is rather sparsely perforated by drops of 

 middle and of the very smallest size; the latter are more 

 numerous upon the posterior than upon the anterior half of the 

 wing. The cells of the wings are all of an unusual breadth, and 

 the crossveins accordingly of an unusual length ; the distance 

 between them is but little shorter than the middle crossvein ; the 

 second and third longitudinal veins are considerably divergent 

 towards the end ; upon the third I do not perceive any bristles.

Observation. I leave this species provisionally in the genus 

 Tephritis; the description shows sufficiently that it is a stranger 

 there, whose affinities point towards the genus Eurosta. To
