4 Fastigium in dorsal view with sides converging in an

obtuse angle, general color green or pale cinnamon, most specimens short-winged, rarely long-winged A.

32[degrees]; dispersion not observed; pleochroism not observed; X < c, Y = b, Z ^ a = 28[degrees] in

obtuse angle [beta].

I complained above against Lucas that no ceiling ever appears in a single view as a quadrilateral having four

obtuse angles, and I questioned whether we are entitled to assume the existence of non-Euclidean appearances if they never appear.

The angle was an

obtuse angle, and I remember thinking as I woke, that had he made it an acute or right angle I should have both suffered and `seen' still more and probably should have died.

The lamination occurs with a laminating roll at an

obtuse angle to avoid air intake (figure 4).

A third, smaller part containing classrooms and a gymnasium meets the ancillary link at an

obtuse angle.

One satisfied by a definition like this is hypnotized by a typical case, where two streets meet at an angle of more or less ninety degrees, and consequently ignores the case in which they meet at an extremely

obtuse angle.

Moreover, the press standstill times are minimized because the acceleration (referred to the gripper) is lower with an

obtuse angle between the two main elements than if the latter are in an extended position, while the effective velocity or distance component is greater.

If a dark-coloured angle in Figure 1(c) is an acute angle or an

obtuse angle, they can see that the other angle (the light-coloured angle) is a reflex angle.

Pronotum short and narrow, collarlike, twice as long as vertex in midline; median carina distinct and complete; intermedian carinae corrugated and curving into posterior margin which is concave in

obtuse angle.

Epicnemium with completely or nearly completely delimiting carina, with large, deep depression anteriorly; two acetabular carinae meeting in medioventral carina to form

obtuse angle (Figs.
