PARKER: NEW KNCILAXU SARCOI'IIAGIDAK. 11 
Proplruru = pro-episternum (pen.). 
Mcsoph'ura = unepisternuiu plus the nvvu \n.-t\\vvu it and the 
pleural suture (a»s. + hp.). 
Sfernoplcura = sternopleurite {sple.). 
Pieroplrura = pteroplcurite (pplr.). 
Hypoplcura = meropleurite plus the lateral hall' of the iiietathorax 
{mple. -\- mtn. + mtem. + mtes.). 
Metapleura = pleurotergite (pt.). 
Sutures of the side of the thorax are as follows : 
Notoplciiral or Dorsopleural: extending from the humerus to just 
in front of the wing base and separating the mesopleura from the 
proscutum (PI. 3, figs. 18, 20, nsu.). 
Mesopleural: that part of the pleural suture which is above the pos- 
terior basal extremity of the mesopleura (PI. 3, figr IS, msii.). 
Sternopleural: separating the mesopleura and sternopleura (PI. 3, 
fig. 18, ssu.). 
The dorsum of the thorax is marked by five longitudinal, blackish 
vittae, a central and two laterals on each side. The three central 
vittae extend back to the scutellum while the second lateral pair 
extends only from the humerus back to the postalar callus. On each 
side of the central or median vitta is a narrow indistinct grayish stripe 
that does not extend much back of the transverse suture. Only the 
three central vittae are prominent and well marked; the two others 
are irregular and ill defined. 
Vestiture. — The mesonotum bears short, scattered bristles, that are 
inclined backward from near the bases. On the scutellum, they are 
slightly longer, more abundant, and erect. On the side of the thorax, 
the vestiture where present is hairy and of varying length. The 
lower portion of the sternopleurite bears several rows of bristles but 
no hair. 
Wings. 
Each wing structure is attached to the mesothorax along an angular 
line that extends downward and l)ackward from near the upper end 
of the pleural suture, and then upward and backward toward the base 
of the scutellum. It may be divided into a larger veined portion 
covered with microscopic hairs and a much smaller lobulated portion
