Anal organs: CoUcmhola ; the two modified hairs arising from a tubercle 



ventro-cephalad of the anus and usually curving caudo-dorsad. 

 Anal orifice: see anus. 



Anal papilla: Collembola ; see anal tubercle. 

 Anal plate: in caterpillars, the shield-like covering of the dorsum of the last 



segment: in the embryonic larva the iith tergite. 

 Anal ring: a chitinous ring encircling the anus in many Coccida. 

 Anal scale: one of the lateral processes of the ovipositor in Cynipidcc, lying 



outside and below the lateral scale. 

 Anal siphon: the anal breathing tube of Culicid larvae. 



Anal style: a slender process on or within the terminal segment of the ab- 

 domen in Hoiiioptcra. 

 Anal tubercle: Collembola; the tubercle bearing the anal organs: r= anal 



papilla. 

 Anal tubercles: a pair of prominent, rounded or conical processes, situate one 



on each side of the anus in certain Coccids. 

 Anal valves: see podical plates. 



Anal veins: those longitudinal unbranched veins extending from base to outer 

 margin below the cubitus ; the first anal, also termed vena dividens, q. v., 

 is the 6th of the series starting from the base, and it may be followed by 

 several others which are numbered in order to the inner margin. 

 Anastomosing: inosculating or running into each other. 



Anastomosis: a running together; usually applied to wing veins, often to 

 markings ; sometimes used like stigma, q. v. ; also in Neuropfera, a series of 

 cross-veinlets nearly in one row : a connecting series of veinlets. 

 Anceps : two-edged ; similar to ensiform, q. v. 



Ancestral: primitive; inherited from an earlier form or ancestor. 

 Anchor process: = breastbone, q. v. 

 Anchylosed: grown together at a joint. 

 Ancipital: with two opposite edges or angles. 

 Androconia: specialized, usually small scales of peculiar form, found localized 



on some male butterflies. 

 Androgynous: uniting the characters of both sexes. 

 Aneurose: a wing without veins except near costa. 



Angle: of tegmina, " is the longitudinal ridge formed along the interno-median 

 by the sudden flexure from the horizontal to the vertical portion when 

 closed." 

 Angular area: Hym.; the posterior of the three areas on the metanotum be- 

 tween the lateral and pleural carinae ; =: 3rd pleural area. 

 Angulate: forming an angle; when two margins meet in an angle. 

 Angulose: having angles. 

 Angulus: forming an angle: := angulate. 

 Angustatus: narrowed; narrowly drawn out. 

 Anisoptera: that division of the Odonata in which the hind wings are wider, 



especially at base, than the front wings. 

 Annectent: applied to connecting or intermediate forms. 

 Annelet or annellus: Hym.; small ring-joints between scape and funicle.
