Spiculum: a small spicule or thin, pointed process. 



Spinate: produced into an acuminate spine. 



Spindle-shaped: cylindrical, elongate, thicker in the middle, tapering to each

Spine: a sharp process: in Coccidcc there are two, one each side of each seg- 

 ment of the pygidium. 



Spinif erous : bearing, or clothed with spines. 



Spiniform: in the form or shape of a spine. 



Spinneret: the ligula in bombycid and some other larvae, modified for silk 

 spinning : any organ consisting of an internal tube, terminating in a pore, 

 spine or process, producing a silky or waxy fibre : in the plural, the organs 

 concerned in the emission of the silky or cottony filaments of which the 

 scales or sacs of Coccidae are produced : = fusulus. 



Spinose -ous -ed: set with acute processes or spines. 



Spinous-radiate: beset with spines in a circle, either concatenate, united at 

 their bases, or setaceous, like bristles.

 or heels. 



Spinulate -ose: set with little spines or spinules. 



Spinules: little spines. 



Spira: the coiled ovipositor of Cynipidcr. 



Spiracle -cula: a breathing pore: q. v.: in the plural the lateral openings on 

 the segments of the insect body through which air enters the tracheae: = 

 stigmata. 



Spiracular area: the anterior of the three areas between lateral and pleural 

 carinas on the metanotum of some Hymenoptera : = first pleural area. 



Spiracular line: in caterpillars is that which includes the spiracles: = 

 stigmatal. 



Spiracular sulcus: on the metanotum of Hymenoptera, is a grooved line or 

 channel extending from spiracle to apical margin. 



Spiral: rolled up like a watch spring, or twisted like a cork-screw. 



Spiral fibre: the spiral thickening or folding of the chitinous lining of a 

 trachea, which gives to the latter its characteristic microscopic appearand- 

 as well as its support and elasticity ; = taenidium. 



Spirignath: = spiritrompe. 



Spiritrompe: the spiral tongue in Lepidoptera. 



Splanchnic: applied to the outer embryonic layer of the rudiment of the mid- 

 intestine : or the inner layer of the mesoderm which, becoming applied to the 

 walls of the alimentary canal, develops into the muscle fibres thereof.
