sericeous -- silky; downy. 



serrate -- saw-toothed (e.g., serrate elytral margin as in Fig. 1 or 

 serrate antenna as in Fig. 120). 



stemite -- a sclerite of the sternum (Figs 1-4, 13). 



sternum -- the ventral part of a body segment. 



stria -- a row of punctures forming a longitudinal line (Fig. 1). 



stylus -- sensory projection of the female genitalia attached to hemi- 

 sternite (Fig. 11) . 



sub- (prefix) -- almost; nearly; slightly; close to; just below, 

 (e.g., subequal; subquadrate.) 



sublateral carina -- a lateral longitudinal carina parallelling the 

 lateral margin (Figs 1, 3). 



submentum -- the basal sclerite of the labium by which the labium is 

 attached to the gula of the head (Fig. 7). 



sulcus (plural, sulci) -- a groove or furrow. 



sutural interval -- the first or median elytral interval (Fig. 1). 



sutural vitta — a vitta or stripe bordering the elytral suture (Figs 

 81, 82). 



suture -- a seam or impressed line between two contiguous sclerites; 

 the median line of juncture of the elytra (Figs 12, 13). 



tarsus -- the foot; the distal part of the leg attached at the apex of 

 the tibia, consisting typically of five joints or segments and bearing 

 the tarsal claws (Fig. 2). 



tergite -- a sclerite of the tergum (the dorsal part of a segment) 

 (Figs 1, 12, 13). 



testaceous -- yellow; brownish yellow. 



thorax -- the body region between the head and the abdomen; the thorax 

 bears the legs and, in adults, the wings. 



tibia -- the joint or segment of the leg between the femur and the 

 tarsus (Fig. 2) . 



tomentum -- a dense patch of hairs, either prominent, as on the tibia 

 (Fig. 2), or closely appressed to the surface and providing a plastron 

 on various body sclerites.
