Part 13

Appendicle: a small appendix: in some bees, a small sclerite at tip of labrum.

Appendiculate: bearing appendages; said of antennae where the joints have articulated appendages; of tarsal claws that have membranous processes at base.

Appendiculate cell: Hymenoptera; is on costa just beyond 2d radius 1 and 2.

Appendigerous: bearing appendages.

Appendix: a supplementary or additional piece or part, added to or attached to another: in Heteroptera; = cuneus, q.v.

Appress -ed: to press against; closely applied to.

Approximate: near to; applies to antennae inserted close together.

Aptera: those that have no wings: an ordinal term formerly employed for fleas, lice and other wingless forms now distributed in other orders: later used for the simplest or lowest insects, including the Thysanura and Collembola.

Apterodicera: wingless, with two antennae.

Apterous: without wings.

Apterygogenea: those insects that are wingless in all stages and presumed to be descended from ancestors which never were winged: see pterygogenea.

Apterygota: = apterygogenea; see pterygote.

Aquamarine -us: sea green: pale green with predominant blue and a little gray [nile green].

Aquatic: living wholly in water.

Aquatilia: cryptocerous Hemiptera of truly aquatic habit.

Arachnoideous: resembling or similar to a cobweb.

Araneiform: spider-like in appearance.

Arboreal: living in, on, or among trees.

Arborescent: branching like the twigs of a tree.

Archaic: ancient; no longer dominant; of the olden time.

Archiptera: those Neuroptera with incomplete metamorphosis = Pseudo-neuroptera.

Arctic Zone: is that part of the boreal region above the limit of tree growth in the U. S. is restricted to the area above timber line on the summits of high mountains: = alpine.

Arcuate: curved like a bow: = arcuate.

Arcuato-emarginate: with a bow-like or curved excision.

Arculus: Odonata; a small cross vein between radius and cubitus near the base, leaving an elongate triangle between them: Trichoptera; a point, often hyaline, on the forewing where the cubitus (or post cubitus) runs into the margin: in Homoptera; a cross-veinlet nearly reaching posterior margin at same point as in Trichoptera: in other orders applied to a cross-vein in similar position, apparently giving rise to the median.

Arcus: a bow; part of a circle; but less than one half.

Area mediastinal, scapularis and ulnaris: the areas in front of the mediastinal, the scapular, and the ulnar veins in Orthoptera.

Areae or Areolae: wing cells or spaces between veins.
