anterior or scutal and a posterior or scutellar region. Each side of the 
scutal region is swollen in front, but the scutellum is not indicated by 
sutures. Posteriorly the scutellar region spreads out laterally. The 
wings on both segments are only attached by feeble, local, restricted 
areas to the front part of the scutum. 
In Tcrmes flavipes (PI. XLII, figs. 1-3) there are important differences 
from Termopsis. 
The pronotum is one-half as long as the head, well rounded behind, 
and one-fourth shorter than broad. 
In the mesonotum the scutum and scutellum are differentiated; the 
scutum is broad and short, one-half as long as broad, and rounded be- 
hind. The scutellum is quite free from it, and is larger than the scutum, 
being longer, with the sides prolonged toward the posterior insertion of 
the wings. 
In the metanotum (Fig. 3) the scutum is very broad and short, shorter 
than the mesoscutum, and only two-thirds as long as the metascutel- 
lum ; the latter is largo and broad, being a little shorter than broad. 
No praj- or postscutellum in either segment. 
The mcso- and metanotum are considerably Narrower than the thorax 
itself, and are margined with membrano, the insertion of the wings 
being tergal and very weak. 
Pleurum. 
Propleurum (Termopsis angusticollis). (Fig. 4.) The sides of the pro- 
thorax are much flattened, as if (seen from above) the body had been 
squeezed and the flanks pressed out, so that they present a rather wide 
lateral area on each side of the tergites. The episteruum forms a nar- 
row (vertically) linear piece. The epimerum is membranous, narrow, 
but wider than the episternum. The coxa and trochantine are consol- 
idated in one large oval-oblong sclerite. 
Mesopleurum. (Fig. 5.) Episternum forming one large, irregular 
piece, expanding above the middle, anteriorly forming a triangle. The 
epimerum is much smaller and semi-membranous. The trochantine is 
large and long, being oblong-ovate; coxa as long as the trochantine, but 
narrower, and pressed up (so to speak) beyond it. 
Metapleurum. (Fig. 6.) Much shorter than that of the mesothorax. 
Episternum much narrower, while the trochantine is broader and much 
shorter in proportion; otherwise much as in the preceding segment. 
In Term.es flavipes (Fig. 4) the pro-episternum is represented by a 
narrow sclerite situated iu front of and below the pronotum, and sep- 
arated from the sternites by a suture. The epimerum is a minute, trian- 
gular sclerite situated over the coxa. The trochantine is large and 
long, and the coxa is of the same length. 
Mesopleurum. (Fig. 5.) The episternum is well developed, narrow, 
curved, triangular. The epimerum is much smaller, and both pieces are | 
situated obliquely. The trochantine and coxa are of the same size and
