The Lacinia in the Maxilla of the Hymenoptera.* [PDF]
Annals of the Entomological Society of America, 1912 The maxilla of biting insects consists of six pieces. There is at the proximal end a two segmented cardo ( c ), which articulates the maxilla to the head capsule (Figs. 1 and 2). Attached to the distal end of the cardo there is in the cockroach (Fig. 1) a rhomboidal-shaped piece, the stipes ( s ). The stipes in the locust (Fig. 2) is also rhomboidal in
