GLOSSARY (After Smith) 



Those muscoid_flies in which alulae are absent or elementary. 



Any glands opening into the ducts of the reproductive system 



(Fig. 32). 

 Specialized, usually small scales of peculiar form, found 



localized on some male butterflies. 

 Hymenoptera; the stingers, including bees and wasps. 

 Reproducing without union with a male. 

 Winged. 

 Periodic productions of parthenogenetic females in a species 



that occurs in both sexes. These females produce both 



sexes. Examples occur in Cynipidae and in some Homoptera. 

 A pair of membranous scales above the halteres, behind the 



root of the wing, one above or before the other; the anterior 



attached to the wing and moving with it, the posterior 



fastened to the thorax and stationary. Occurs in Diptera. 



Synonyms calyptra; squama; squamula; lobulus; axillary 



lobe; aileron; scale; tegulae. In Coleoptera a membranous 



appendage of the elytra which prevents dislocation. 

 The lobe at basal portion of wing in Diptera (posterior lobe). 



Sometimes used for alula. 

 The inner of the two membranes enclosing the embryo 



(Fig. 36). 

 That angle on the secondaries nearest the end of the abdomen 



when the wings are expanded. The angle between the 



inner and outer margin of any wing. 

 In Orthoptera and Neuroptera the hinder or anal portion of a 



wing within the anal vein. 

 In caterpillars the shield-like covering of the dorsum of the 



last segment (Fig. 18). 

 Without wings. 

 A specialized bristle or process on the antenna; of certain 



Diptera (Fig. 180). 

 Jointed animals having jointed appendages. 

 Having short three-jointed antenna;, Diptera (Fig. 144). 

 A blind sac or tube supplied to appendages, opening into 



the alimentary canal at the junction of the mid and hind 



gut (Fig. 29).
