Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1892 edition. Excerpt: ...two lateral halves by a distinct suture. Its outer extremities articulate with the anterior margins of the epitrochlear sclerites, and with the inner and lower part of the paratremes. Each lateral half is divided into two by a distinct oblique suture, which extends from the attached edge of the prophragma downwards, outwards and backwards, and terminates in a strong apodeme, which projects into the thoracic cavity, the prothoracic apodeme. The Paratreme (20) is seen best from the interior of the thorax. It is a distinct and irregularly quadrate sclerite, bounded above and internally by the prescutum and the prophragma, below by the extremity of the prodorsal arch, and externally by the spiracle, above which it just reaches the lateral plate and the dorso-pleural syndesmosis. Although the limits of the paratreme are not very readily seen externally, they are marked by a very distinct sutural ridge projecting into the thoracic cavity. The Epitrochlear Sclerite is a quadrangular vertical plate, articulating with the paratreme and prodorsum above, and with the condyle by its inner margin. Its external surface is convex, and projects in a tooth-like process, overhanging the anterior coxa in front. The external edge of the epitrochlea is formed by the descending process of the hypotreme. The Sclerites of the Prosternal Area are nine in number: the manubrium, two pairs of claviculas, anterior and posterior, and two pairs of pectoral sclerites, the greater and lesser pectorals. In the immature imago these sclerites are all distinct chitinous thickenings of the syndesmotic integument; but in the mature insect the claviculas are fused with the manubrium and the epitrochlear sclerites. The Claviculae.--The anterior clavicula is a thin rod of chitin, ..show more
