GLOSSARY OF TECHNICAL TERMS. 



Ah. in composition signifies away from, deparature from, as abnormal, 



departing from the usual rule. 

 Abdomen, the posterior of the three main divisions of the body ; but the term 



is often loosely applied by Coleopterists to the ventral segments only. 

 Aborted, incomplete, undeveloped. 



Acetalnda, another name for the coxal or cotyloid cavities. 

 Acicidar, slender, needle-shaped. 

 Aciculate, covered with small scratches. 



Aculeate, produced into a point ; or, as applied to one group of Hymenopteka, 



furnished with a sting. 

 Acuminate, terminating in a point. 

 Mneous, of the colour of brass, brassy. 



Mdeagus, the intromittent organ of the male with its appendages. 



Agglutinate, fastened closely together so as to form one piece. 



Alutaceous, covered with minute cracks, like dry mud, or like the human skin.

Anal, pertaining to the apex or extremity of the abdomen. 

 Annulate, with coloured rings. 



Ante-, in composition means before : e. g. anteocular, situated before the eye.

Apical, relating to the extremity. In the Coleoptera all the parts of the body 

 are described in relation to an imaginary central point, between the 

 prothorax and the elytra ; the part nearest this is the base, the point 

 furthest from it the apex. Thus the apex of the prothorax is the front 

 margin ; but the apex of the elytra the hindmost margin ; the base of 

 the thorax meets the base of the elytra. 



Apodal, without legs, of certain larvse. 



Apophysis, an extra projecting piece or the prolongation of an existing organ 



(e. g. the coxal apophyses in Dytiscus). 

 Appendiculate, furnished with appendices or additions : of lines, furrows or 



organs of the body. 

 Apposed, with their surfaces lying one against the other. 



Apterous, without wings; often, however, used loosely of insects with aborted 



or rudimentary wings.
