£. TEGMINA. 
1. Fenestrella (Fencstrella). A transparent eye-like 
spot in the Anal Area of the Tegmina of Acrida 
2. Con vol vent (Convolventia). When the Anal Area 
is horizontal, incumbent on the back of the insect, 
and forms a right angle with the rest of the teg- 
men, which is vertical and covers the sides. — Ex. 
Locasta. N.B. In this case the Anal Area of one 
Tegmen covers that of the other. 
3. Aliform (Alifonnia). When their substance ap- 
proaches to membrane, and they nearly resemble 
Wings. — Ex. Most Homopterous Hemiptera. 
Yl. HEMELYTRA. 
1. Obtected (Obtecta). When the Hemclytra are 
covered by a scutelliform mesothorax. — Ex. Scu- 
tellera. 
2. Detected (Detecta). When they are not so co- 
vered. — Ex. Most Heteropterous Hemiptera.

A. Denomination. 
1. Anterior (Antica?). The fore or upper wings. 
a. Superior (Superiores). The anterior wings are so 
denominated if when at rest they are placed upon 
the posterior wings. — Ex. Hymenoptera.

denominated if when at rest they are not placed 
a For the reason of this change of the name of Locusta F., see
