Spiloblattina lineata sp. nov. Pl. LXXXI, fig. 1. , 
Tegmina very slender, three times as long as broad, scarcely 
at all curved, outer and inner margins parallel; apex obtuse, 
placed somewhat above the middle line of the wing and pointed 
slightly upward. Subcostal area narrow, extending about two- 
fifths the length of the wing, and sending several nearly 
straight, parallel, oblique branches to the costal border. Ra- 
dius branched near the base, about opposite the middle of the 
anal area; six branches in the type specimens are given off, the 
first five of which are forked. The radial area reaches just to 
the apex. The media is simple until beyond the middle of the 
wing. It gives off four branches, the first three being com- 
pound. The cubitus is sinuous and extends about three- 
fourths the length of the inner border. The branches are 
simple, arched, parallel, and unusually strong, especially those 
towards the distal end of the cubitus. The anal area is rather 
long and narrow, and is well marked. It is provided with 
about seven simple veins. The sixth and seventh anal veins 
of the type are united throughout the distal third of their 
length, presenting in this respect an anomalous condition, and 
doubtless indicating a process of reduction in the number of 
anal veins. Length of wing, 24 mm.; breadth, 7 mm. 
The tegmina is straighter and more slender than that of 
S. maledicta; the first radial branch originates earlier, the 
anal area is more narrow and the anal veins more numerous. 
The distribution of the radiomedian and mediocubital inter- 
spaces is similar to that of S. maledicta. The branches of the 
cubital, however, particularly the distal ones, are noticeably 
stronger. Specimen No. 18, University of Kansas collection, 
probably belongs to this species. The tegmina is slender. The 
first two cubital branches are united in their distal part.

Spiloblattina curvata sp. nov. Pl. LXXX, fig. 3. 
Teemina strongly arched, elongate. Subcostal area broad; 
branches from the subcosta mostly simple, oblique. Radius 
strongly curved at the base. The first branch is given off 
opposite or back of the end of the anal area. The media is
