Armature: applied to the spinous or chitinous processes on the legs, body or wings; or the corneous parts of genitalic structures. Armatus: set with spines, claws or other chitinous processes. Armillate: with a ring or annulus of raised or different tissue. Arolium -ia: cushion-like pads on the tarsi of many insects: one of the lobes of the pulvillus; in Orthoptera, used only for the terminal pad between the claws: see empodium; pulvillus; palmula; plantula; onychium, paronychium, pseudonychium. Arquate: see arcuate. Arrhenotokous: capable of producing male offspring only, as in worker bees and some saw-flies. Arrhenotoky: parthenogenetic reproduction when the progeny are all males: see thelyotoky and deuterotoky. Arthrium: Coleoptera; the minute, concealed tarsal joint in pseudotetramera and trimera. Arthroderm: the outer skin or covering of articulates. Arthrodial: an articulation that permits motion in any direction. Arthromere: a body segment or ring: = somite. Arthropleure: the side piece of an arthromere. Arthropods: all those articulates having jointed legs. Article: a joint or segment. Articular pan: the cup or dish-like depression forming the socket into which an articulation is fitted. Articulate: that branch of the animal kingdom whose members are made up of rings, segments or articulations. Articulate: divided into joints or segments. Articulated apex: see clasp filament. Articulation: the point or place where two parts or segments are joined: also applied to an individual joint or segment. Articulatory epideme: the partly chitinized membrane by which the wings are attached to the thorax. Artus: the organs of locomotion generally. Asexual: applied where the reproductive organs are incompletely developed and eggs or young are produced by cell-budding: = parthenogenetic. Ash-gray: a mixture of black and white, with a faint orange tinge: like ashes of anthracite coal. Aspect: indicates the direction to which a surface faces or in which it is viewed; it may be dorsal, ventral, caudal, cephalic or lateral. Asperities: surface roughenings or dot-like elevations. Aspersus: rugged, with distinct elevated dots. Assembling: gathering together; applied when a virgin female is exposed to attract such males as may be near, either to secure a pairing or merely to obtain specimens; also called sembling. Assurgent: down-curved at base, then upcurved to an erect position. Asymmetrical: not alike on the two sides; not symmetrical. Asymmetry: a state of unlikeness in lateral development; absence of symmetry in form or in the development of members. Ater: deep black; not shining. Aterimus: the deepest black. Athericerous: see aristate. Atom -us: a minute dot or point. Atomarius: with minute dots or points. Atrachelia: Coleoptera in which there is no visible constriction between head and prothorax: Rhynchophora and some Heteromera.
