INSECTA. 
ORTHOPTERA. 
Pyenoscelus (?) gardneri, sp. n. (Blattide). 
Tegmen about 30 mm. long and 12 broad ; marginal field 
broad, with elevated and broadly rounded base, the width 
(depth) of the field near base 3 mm. ; subcosta and branches 
of radius very oblique ; subcosta running parallel with first 
branch of radius (its total length from base of tegmen 
12-7 mm.), giving off a branch about 4°2 mm. from end, and 
another, rudimentary, one about 1°5 mm. earlier; radius with 
very numerous superior branches, first simple, second and 
third with long forks, fourth with short fork, fifth with two 
long branches, sixth and seventh each with a long fork, the 
forked branches with long stems; radial sector arising about 
11°5 mm. from base of tegmen ; media and cubitus between 
them with about nine principal branches, between which are 
conspicuous supplementary veins; cross-veins present. The 
inferior basal area of tegmen is lost.

This agrees with the modern Pycnoscelus surinamensis (L.) 
in the broad marginal field, general size of tegmen, two- 
branched subcosta, general character of branches of radius, 
early origin of radial sector, and numerous branches of media, 
with supplementary veins between. There are no visible 
differences which could possibly be regarded as of generic 
value ; but as we have only an incomplete tegmen, the generic 
reference must be considered provisioual. The amber Blattida 
are very different. 
Allopterites (gen. nov.) multilineatus, sp. n. (Gryllide). 
Lower wing as preserved 19 mm. long, but probable total 
length about 23 mm. 
Costa nearly straight ; subcosta, radius, and media running 
parallel below it, the intervals between them less than the 
width of the veins; media giving off very numerous (many 
more than in Gryllus) oblique brauches, which are directed 
toward the apex of the wing ; all these veins are ferruginous 
as preserved, and ‘the branches of the media are obliquely 
crossed by numerous (four in 2 mm.) continuous veins of the 
same colour, directed upward and outward (like the cross-veins 
in Mantoida), forming angles of about 45° with the branches. 
These oblique cross-veins abruptly cease at the lowest branch
