This species looks very much like a Blattella but the venation of the wing 

 is that of an Ischnoptera or rather an Ischnopterite as that large genus is much 

 too comprehensive and should be restricted after examination of large series of 

 the species referred to it. 



Gen. — Blattella, Caudell. 



Blattella germanica, L. 



Mesopotamia: Kurna, 20-5-18, Id; Amara, 27-11-17, 1$ ; 10-6-18, 19 ;

 Cosmopolitan species. 



Gen. — Stjpellina, nov. gen. 



Very closely allied to Supella Shelf. Male narrow and elongate, with tegmina 

 and wings extending beyond the apex of abdomen. Head with eyes well 

 separated ; interoeular space flattened, forming with the facial shield a sub- 

 angular line. Tegmina with the discoidal sectors oblique ; wings with the ulnar 

 vein ramose, no apical triangle. Dorsal segments of abdomen unspecialized ; 

 supraanal plate very weakly pi'oduced ; subgenital plate with styles well devel- 

 oped, almost symmetrical, inserted near the apex of the plate. Front femora 

 armed anteriorly with two long apical spines and a row of very short, spiniform 

 bristles, posteriorly with one apical spine and one before the apex of the inferior 

 edge. Femora of the other legs armed with a few spines on each edge. Female 

 unknown.

Type: One male from Mesopotamia, Amara (P. A. Buxton, 14-9-1918.) 

 ^ . Size medium, form slender. Colour very pale yellowish with two 

 brown longitudinal bands on the pronotum, and numerous longitudinal brown 

 lines on the elytra between the principal veins. Head elongate ; occiput 

 short, brown ; interoeular space wide ; front, between the ocellar spots, 

 whitish ; face brown. Maxillary palpi long, brown, the last segment short, 

 truncate. Antenna3 brown. Pronotum broad, slightly convex, anterior and 

 posterior margins almost straight, lateral margins convex ; disk pale yellowish 

 marked with two brown bands converging anteriorly ; lateral portions trans- 

 parent. Meso and metanotum testaceous. Abdomen testaceous with two 

 brown lateral lines ; supraanal plate, very short, subrounded at the apex ; 

 subgenital plate rather large and produced, emarginate at the apex, depressed 

 on each side with a longitudinal keel in the middle. Cerci formed of 12 articles, 

 depressed with their outer angle somewhat produced and rounded, the two 

 distal ones much smaller. Style rather big, inserted almost in the midst of the 

 posterior margin of the plate, armed with two very minute denticulations at 

 their apex ; the superior margin of the subgenital plate bearing 2 or 3 such den- 

 ticulations at their base. Genital valves showing a long chitinous process and a 

 rounded head entirely covered with stiff bristles. Legs rather long and slender, 

 yellowish. Front femora armed anteriorly with two apical spines very close to- 

 gether, the superior one longer and curved, posteriorly with one apical spine and 

 one about at the distal third of the inferior margin ; anterior margin bearing about 

 30 spinuliform bristles from proximal third to the apex ; tibise shorter than the 

 femora, armed with 4 apical spines, 3 superior (1 ext., 2 int.) and 2 inferior ones. 

 Intermediate and posterior femora armed with 4 or 5 spines on each margin
