Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1850 edition. Excerpt: ...together with its scutellum, is covered with a short golden down. The elytra at the base are considerably wider than the prothorax, and altogether wide in proportion to their length, still sufficiently long to conceal the abdomen; they gradually decrease in width towards the apex, where they are rounded but furnished with a small yet very obvious marginal tooth at some distance from their sutural extremity; besides the suture itself, which is somewhat keel-like and glabrous, each elytron has two glabrous discoidal keels, the first nearest the suture is very decided, it commences at the base and terminates near the apex, it is perfectly glabrous, impunctate, and of a bright yellow colour: the second commencing at the shoulder of the elytron and running parallel to the first, is glabrous, impunctate and black, a small apical portion alone excepted, which is yellow; the interstices between these keels as well as the space exterior to them is black, glabrous, and coarsely and deeply punctate. Beneath, the prothorax is punctate as above, it fonns a truncate cone, no ridge or line of demarcation separating its dorsal and sternal surfaces; the metasternum is black and very polished, but more deeply punctate than the prosternum; anteriorly it is produced into a strong tooth-like projection, and on each side it has an amorphous pale-coloured patch of velvety down: the abdominal segments are black, brilliantly polished, and under a lens of moderate power appear to be impunctate; the terminal segment is exserted and truncate at the tip. The fore and middle legs are of average size and proportions; the hind legs are long, the tip of the abdomen not nearly reaching the extremity of their femora; all the femora are manifestly incrassated externally, ..show more
