THE EXO-SKELETON OF THE I'KOBOSCIS. .33 a basal joint, the cardo, c, which supports the stipes, s, or second joint. Three lobes are articulated with the stipes—the first, or external lobe, is usually reduced to a small scale which sup- ports the palpus; it is the palpiger, /. The second lobe, or upper lobe of Kirby, frequently forms a large hood in which the third, or internal, lobe lies when at rest. This second lobe is the galea, g. It almost always consists of, at least, two joints, and is usually soft and fleshy. In a few Coleoptera, as the. 1'IG. 26.—Details of the Maxilla and Labium, after Brulle : /, maxilla of Locusta viiidissima ; 2, of Blaps ; j, of Pepsis sp. ; 4., of Xylocopa violacea ; s> of "n Australian species of .'Eschna : ,?•, galea; /, lacina: g', sous-galea; s, stipes; />', palpiger ; c, cardo ; 6, labium of Copris Isidis : /', lacina or inner blade of second maxilla ; lig, ligula ; ^, outer lobe (galea) ; /, palpus. Tiger-Beetle {Cicindela), the galea is palpiform, and is usually termed the second maxillary palpus [Newport, 9, p. 8go]. The third lobe, or lacina, I, is frequently a cutting blade, and some- times has a small claw, the uncus, articulated with it near its extremity. In some phytophagous insects the lacina is con- verted into an obtuse lobe covered with setae. The improbability that so complex a structure can become a mere seta is, to my mind, very great; but when it is 9—2.
