To quickly assess the difficulty of the text, read a short excerpt:
The inner mouth organs are all much lengthened, which makes them not unlike the sucking oral appa- 86 GENUS MEGALODONTES. ratus of bees. The outer lobe of the maxilla is much longer than the inner ; the stipes is divided in two ; namely, the main piece and a smaller lateral piece to which the palpi are attached, and which is prolonged to the base of the stipes (Vol. II, PL VI, fig. 10 b). From the top of this piece a horny belt proceeds to the labium, which is thus firmly united to the maxilla.... The palpi do not reach much above the top of the long outer lobe of the maxilla. The labial palpi do not reach the top of the lobes of the labium. The thorax is arched on upper side, not much longer than broad; the prosternum projects a little so that the head has considerable powers of movability ; the pronotum is broadly rounded behind. The middle lobe of the mesonotum on this account is but slightly developed ; the sutures of the lobes are not always very clearly distinguishable; the abdomen has the blotch long, narrow ; the abdomen itself is rather flat, but still arched on upper side.
