Sub-pedunculate: in Colcoptera, when the constriction between pro- and 



mesothorax is so great as to give the appearance of a narrow waist. 

 Subreniform: a rounded spot or outline, below and sometimes attached to 



the reniform spot in Catocala and some allied Noctuids. 

 Sub-parallel: nearly parallel. 

 Sub-primary sub-ventral tubercle: on the thoracic and abdominal segments 



of caterpillars ; sub-ventral, posterior, not present in the primitive first 



stage ; it is VI of the abdomen, V of the thorax : constant. 

 Sub-sellate: nearly like or approaching the form of a saddle. 

 Sub-servate: denticulate. 

 Subspecies: a well-marked form of a species differing from the type in 



some character of color or maculation which is recognizable but does not 



prevent a fertile union : an indefinite and opinionative division. 

 Subspiracular line: in caterpillars, margins the spiracles inferiorly. 

 Substigmatal: that portion of the marginal cell below the stigma, in bees: 



= 1st radial 1 (Comst.) : applied to a line in caterpillars = subspiracular. 

 Sub-teres: nearly but not quite cylindrical. 

 Subtile -is: slightly; feebly; small; pretty; graceful. 

 Subtriangular space: = internal triangle: see triangle. 

 Subtus: beneath; at the under surface. 

 Subulate: awl-shaped; linear at base, attenuate at tip. 

 Subulicornia: with awl-shaped antennae; applied to a combination of Odo- 



nata and Ephemerida. 



Subuliform: formed like an awl: = subulate. 

 Sub-ventral line: in caterpillars, extends along the sides just above the base 



of the feet at the edge between lateral and ventral. 



Sub-ventral ridge: in slug caterpillars extends longitudinally along the sub- 

 ventral series of abdominal tubercles. 

 Sub-ventral space: in slug caterpillars is the area on each side, between the 



lateral ridge and the lower edge of the body, and contains the spiracles. 

 Succincti: those chrysalids of butterflies which are held in place by a silken 



cord passing around the body: see suspensi. 

 Succineous: resembling amber in color or appearance. 

 Sucking pump: in sucking insects, a thick-walled muscular enlargement of the 



oesophagus that serves to draw up the liquid food = pharyngeal pump. 

 Sucking spears: the mandibles and maxillae of Hemerobiid larvae, used for 



puncturing prey and sucking its juices. 

 Sucking stomach: a thin-walled muscular pouch connected with the end of 



the oesophagus ; serves as a food reservoir and is not commonly present 



except in some Lepidoptera. 

 Suctoria: an ordinal term proposed for fleas. 

 Suctorial: adapted for sucking: see haustellate. 

 Suctorial vesicles: bladder-like structures connected with the oesophagus in 



mosquitoes supposed to assist in blood-sucking ; but this is disputed. 

 Suffused: clouded or obscured by a darker color. 

 Suffusion: a clouding, or a spreading of one shade over another. 

 Sulca: grooves, furrows or channels: plural of sulcus.
