130 EXPLANATION OF TERMS 



Stomatogastric: that system of nerves and ganglia, lying along the dorsal 

 and lateral surfaces of gullet and crop. 



Stomatotheca: that part of the pupa covering the mouth structures. 



Stramineous -eus: straw yellow [pale clay yellow]. 



Strangulate: constricted, as if by bands or cords. 



Stratified: arranged or made up in layers. 



Strepsiptera: twisted-wing: an ordinal term proposed for the parasitic 

 Stylopidce, now ranged as a family of Coleoptera = Rhipiptera. 



Stria: in Coleoptera, a longitudinal depressed line or furrow, frequently 

 punctured, extending from base to apex of elytra : in Lepidoptera, a fine 

 transverse line : in general, any longitudinal impressed line. 



Striate-ed: marked with parallel, fine, impressed lines; or, in Lepidoptera, 

 with numerous fine transverse lines. 



Stridulate: to make a creaking noise by rubbing together two ridged or 

 roughened surfaces. 



Stridulation: a creaking sound produced by rubbing together two striated 

 or otherwise roughened surfaces : the act of stridulating or the noise pro- 

 duced by it. 



Striga: a narrow, transverse line or slender streak, either surface or im- 

 pressed. 



Strigate: having striga: applied to a surface on which the striga are im- 

 pressed as in the elytra of some beetles, or to an ornamentation composed 

 of fine, short lines. 



Strigile-is: maculation that consists of parallel longitudinal lines: a deep 

 sinus near base of first joint of anterior tarsus. 



Strigillate -ation: stridulate -ation ; q. v. 



Strigose: clothed with rigid bristles that are thickest at base: rough, with 

 sharp bristles : = hispid. 



Strigula: a fine short transverse mark or line. 



Strigulated: with numerous strigulse. 



Striolate -us: with finely impressed parallel lines. 



S. T. space: the area between the t. p. line and s. t. line in moths. 



Stripe: a longitudinal streak of color different from the ground. 



Style: in Aphids, the slender tubular process at the end of the abdomen: 

 in Coccids, a long spine-like appendage at the end of the abdomen of the 

 male; = genital spike: in Diptera, the ovipositor (Loew) ; the single im- 

 movable organ immediately below the forceps in male Tipulidce (O.-S.) ; a 

 thickened jointed arista at or near the tip of the third antennal joint : in 

 the plural form applied to small, usually pointed, exarticulate appendages, 

 most frequently found on the terminal segments of abdomen. 



Stylet: a small style or stiff process: one of the piercing mouth structures 

 in Diptera and Hemiptera. 



Styliform: in the shape of a stylus: terminating in a long slender point, like 

 the antennae in some Diptera. 



Stylopized: infested by a member of the Stylopida. 



Stylotrachealis: with a long tube bearing a stigma, from the head case; as 

 the pupae of some Diptera.
