Cristiform: in the form of a sharp ridge or crest. Cristula: a small crest. Cristulate: with little crescent-like ridges or crests. Croceous: saffron yellow; yellow with an admixture of red [pale cadmium yellow]. Crocus: =croceous. Crook: the hook or recurved tip of the antenna in Hesperidae. Crop: the dilated portion of the alimentary canal behind the gullet which serves to receive and hold the food previous to its slower passage through the digestive tract: = ingluvies. Crotchets: the curved spines or hooks on the prolegs of caterpillars and on the cremaster of pupae. Crown: the top of head in Lepidoptera; also used as = coronet or corona. Cruciate: shaped like a cross; applied to wings when the inner margins lie one over the other; or to incumbent wings that overlie only at the apex: in Diptera, applied to bristles when they cross in direction. Cruciato-complicatus: folded crosswise: incumbent wings when the inner margins overlap; not well distinguished from cruciate. Crura: the legs or, more specifically, the thighs. Crura cerebri: two large cords that connect the supra- with the sub-oesophageal ganglion. Crus: a leg or leg-like structure. Crustaceous: hard, like the shell of a crab. Crypto: hidden, concealed. Cryptocerata: a division of Heteroptera with small antennae concealed in a groove under the bead: = adeloceratous: see gymnocerata. Cryptogastra: with the venter or belly covered or concealed. Cryptopentamera: feet 5-jointed, the 4th joint small and concealed. Cryptotetramera: feet 4-jointed, one of them small and concealed. Cryptothorax: a supposed thoracic ring between meso- and meta-thorax. Crypts: minute secretory follicles or cavities: specifically, large gland-like structures between the epithelial cells in chylific ventricle. Crystalline: transparent, like crystal. Crystalline cone: a conical structure below the cornea, imbedded in pigment cells of the compound eye: also termed Crystalline lens. Ctenidium: a comb-like structure occurring on any part of an insect. Cubital: referring or belonging to the cubits. Cubital cell: the wing area between the cubits and anal vein; in the plural, all the cells bounded anteriorly by the cubits or its branches (Comst.); in Diptera (Schiner), = radial 3 (Comst.), = 3d posterior cell (Loew); in Hymenoptera (Norton), = radial 3, 4 and 5 (Comst.). Cubital forks: the branching or points of separation of the branches of the cubits. Cubital nerve or vein: see cubits. Cubitus: of Comstock, is the 5th in the series of longitudinal veins extending from base, and usually two branched before reaching outer margin: in Orthoptera; = the internomedian and ulnar: in Neuroptera, a main longitudinal vein next behind the medius and before the anal: the tibia of the anterior leg.
