4GG SAMUEL II. SCUDDER ON 



been very small. An under surface is exposed on the dirty light brown stone, scarcely 

 darker than the stone itself, with veins and intercalaries black; the surface is almost 

 perfectly Hat, only a slight concavity being discernible, and the veins are elevated in the 

 slightest possible degree. 



The length of the fragment is 8.5 mm.; probable length of the wing, 13.5 mm.; its 

 breadth, 5.75 mm. The specimen comes from thePurbecks of Wiltshire, England.

A specimen received from Rev. Mr. Brodie seems to me to represent pretty cer- 

 tainly the original of his illustration of this species (represented, as usual, reversed on 

 his plate). But even if it is not, it certainly belongs to the same species, and its exam- 

 ination shows that, as in the single specimen of E. Kneri,the base is badly broken, and 

 about aquarter of the tip lost; nevertheless the most important part of the neuration re- 

 mains and enables us to restore the wing with considerable confidence, by which it 

 would appear to be nearly two and one-half times longer than broad and to have had a 

 more convex costal margin than E. Kneri. An under surface is exposed, of the same 

 color as the dirty brown stone on which it lies, with black or blackish brown veins 

 and intercalaries. The surface is flat or scarcely concave, the veins scarcely elevated, 

 and the intercalaries slightly sunken. The mediastino-scapular vein is moderately and 

 very regularly arcuate throughout, terminating probably just above the extreme tip of 

 the wing, its branches quite as in E. Kneri; the width of the costal "area, which is broad- 

 est just before the middle of the wing, is here scarcely less than half that of the wing. 

 . The externomedian and internomedian branches, by a strong arcuation at base, almost 

 immediately take on a longitudinal and parallel course, filling the space below with very 

 straight veins, those of the externomedian occupying apparently a very narrow space on 

 the extreme tip of the wing. On their basal half or third, farther out next the inner 

 margin than above, these veins are crossed by numerous cross veins, and in the same 

 place as in E. Kneri is a pretty huge roundish dusky patch. There are intercalaries be- 

 tween all the veins. The anal furrow, which is perfectly flat, is bent in the middle at a 

 broad angle in the same direction as the inner angle of the wing. 



The length of the fragment is 5.5 mm.; the probable length of the wing 7.75 mm.; 

 its breadth 2.1 mm. The specimen comes from the English Pnrbecks and bears also the 

 name "Blake," probably the collector.

Two specimens, submitted to me by Mr. Brodie, represent this species, neither of 

 them with the base quite perfect, and one with about one-fifth broken from the tip.
