Scapula, that segment that is situated one on each side of the 



peristaethium, on the anterior lateral angle of the postpectus. 



immediately beneath the humeral angle of the elytrum ; it is 



bounded behind by the parapleurum. 

 Scopus, scape; the second articulation of the antennae, often 



elongated; it is the " bulbus" of Linne, and "lefuseau" of 



Degeer. 

 Scopa, thick hair, covering the posterior tibice of some Hyrnen- 



optcrous insects; it is used in collecting and carrying pollen. 



See scapula and corbicula. 

 Scopula, bristles or rigid hairs, in some Hymenopterous insects, 



covering the inside of the plantse, principally those of the pos- 

 terior feet; it is very conspicuous in polleniferous insects ; it 



is the " scopa" of Schrank, and " la brosse" of Reaumur. See 



scopa, fimbria, flocculus. 

 Serijitus, lettered ; marked with various characters resembling 



letters. 

 Scrobiculated, pitted; having the surface covered with hollows;

 Secund, pointing one way ; unilateral. 

 Securiform, hatchet-shaped ; triangular-compressed like the iron 



part of a hatchet. See doldbriform. 

 Segment, of the abdomen, is a ring or division of that part, and

 Semicomplete, (metamorphose) in this kind of change the insect 



continues active and feeds, as in Grillus. See coarctate, in- 

 complete. 

 Semicylindric, flat on one side ; the form of the longitudinal 



half of a cylinder. 

 Semisagittate, half arrow-shaped ; like the longitudinal half
