Nannoblattina Woodwardi sp. nov. 

 PI. 48, fig. G. 



This minute species is represented by a single nearly perfect wing, broken obliquely 

 across the base. An under surface is exposed on the dark greenish gray stone, as ap- 

 pears from its slight concavity, and the prominent veins; the wing is fuliginous and the 

 stout veins broadly marked in black. The wing is comparatively broad, the costal and 

 inner margins straight and parallel, the tip broadly rounded, the apex slightly above the 

 middle. The mediastino-scapular vein runs in an obliquely and gently sinuous course, 

 terminating below the apex and broadest in the whole apieal third of the wing, where it 

 occupies fully half of its width, furnished with considerably arcuate, rather numerous, 

 parallel, simple, oblique branches. The externomedian vein arises from this in the mid- 

 dle of the second fourth of the wing and is but once forked, near the tip. The inter- 

 nomedian vein is strongly sinuous, the area rapidly narrowing and the branches very few, 

 short and somewhat divergent. The anal furrow is scarcely or not at all more distinct 

 than the other veins, is strongly arcuate and. must enclose a very large anal area, but the 

 broken wing will not allow us to determine how much; it is probable, however, that it 

 reaches nearly to the middle of the wing; the anal veins are simple, parallel, impinge on 

 the margin, the basal ones turned apically a little outward. 



Length of fragment 3.75 mm.; probable length of wing 4.1 mm.; its breadth 1.6 nun. 

 It comes from the Wiltshire Purbeeks, was received through Rev. Mr. Brodie and is 

 named for Dr. Henry Woodward who has introduced to us so much of the life of the. 

 past.

In this genus the externomedian vein has become completely amalgamated, not with 

 the mediastino-scapular but with the internomedian. The humeral field again appears 

 and, notwithstanding the amalgamation mentioned, the mediastino-scapular area occupies 

 a very large share of the wing - , which is of a tapering, cuneiform shape in the only species 

 known. The veins are, therefore, branches of two principal stems which pass down the 

 middle of the wing side by side, but as distant as the principal branches from each other. 



The single species comes from the English Purbeeks. 



Dipluroblattina Bailyi sp. nov. 



PL 48, fig. 5. 



A nearly perfect wing represents this species in which the anal area only is wanting, 

 excepting a minute fragment of the tip. It has a tapering, graceful form, both costal and 

 inner margin being similarly and gently arcuate and the slender tip being well rounded. 

 A smooth and flattened humeral field, lanceolate in shape, extends over about a third of 

 the wing. The mediastino-scapular, strongly arcuate near the base, runs in its apical half 

 nearly through the middle of the wing ; terminating scarcely above the tip; its rather 

 numerous branches, simple at first, beyond simple or forked, are oblique and tolerably
