Archive image from page 192 of The anatomy, physiology, morphology and. The anatomy, physiology, morphology and development of the blow-fly (Calliphora erythrocephala.) A study in the comparative anatomy and morphology of insects; with plates and illustrations executed directly from the drawings of the author; CUbiodiversity4765349-9885 Year: 1890 ( THE THORACIC EXO-SKELETON. 167 The Scutellum (/) is a pouch-like projection overhanging the posterior part of the thorax and the base of the abdomen (Plates VII. and VIII.)- It is connected with the scutum by a pair of divergent ridges, which arise from its outer anterior angles; these are the scutellar bridges of Loew [77]. De- scending from the root of the scutellar bridge, a process of the scutellum forms the upper edge of the posterior alar- apophysis (Plate VII., b /). It bounds the outer edge of Fig. 35.—Dorsal view of llic Thorax of the Hlow-fly : /, Scutellum ; 2, scutum ; 3, prcscutum ; 4, scutal sjiine ; J, proplerygium ; 6, costal, 7, subcostal and hypocostal nervures forming the remigiuni ; S, patagium ; 9, lobulus of the wing ; 10, scjuamula ; //, squama; 13, scutellar bridge ; 13, posterior alar apophysis. the supra-tympanic fissure, and the great wing scale (//) is attached to it. The Lateral Aspect is represented in Plate VII., Fig. i. Near its anterior margin the large anterior spiracle (/p) will be readily recognised by its orange-yellow colour. Start- ing from the upper margin of the spiracle, and extending back to the wing root h, there is a deep suture, the dorso- pleural suture. It is the anterior part of an extensive syndesmosis {e, f, g, h), the alar syndesmosis. Descend- ing vertically from the dorso-pleural suture between the plates numbered i8 and 28 is the mesopleural syndesmosis.
