USED IN ENTOMOLOGY. 131 



Stylus: a small, pointed, non-articulated process. 



Sub-: as a prefix, means that the main term is not entirely applicable, but 



must be understood as modified in some way ; e. g., sub-ovate, may be 



either more or less than ovate and may be irregular in outline. 

 Sub-aduncate: somewhat hooked or curved. 

 Sub-anal plate: Orthoptcra; = sub-genital lamina; q. v. 

 Sub-apical lobe: of c? genitalia in Culicids is the inner sub-apical lobe of 



the side piece. 



Sub-apterous: almost wingless; with rudimentary wings only. 

 Sub-clavate: somewhat thickened toward tip; but not quite club-shaped. 

 Sub-coriaceous: somewhat leathery. 



Sub-cortical: beneath the bark; as in larval borings, etc. 

 Subcosta: (Comst.) ; that longitudinal vein extending parallel to the costa 



and reaching the outer margin before the apex ; not branched as a rule : 



of Packard, in Hymcnoptera, = radius (Comst.). 

 Subcostal cell: in Diptera (Schiner), = marginal cell (Loew), = radial 1 



(Comst.) : in the plural (Comst.), all those cells anteriorly margined by 



the subcosta : first s. c. cell in Hymcnoptera (Pack.), = radial and first 



radial 1 (Comst.). 

 Subcostal cross-veins: in Odonata, are between subcosta and media on the 



basal side of the first antecubital. 



Subcostal fold or furrow: lies between costa and radius. 

 Subcostal nervule: Lepidoptera, on secondaries = media 1 (Comst.) : s. c. 1 



= radius 1 (Comst.); s. c. 2 = radius 2 (Comst.); s. c. 3 = radius 3 



(Comst.) ; s. c. 4 = radius 4 (Comst.) ; s. c. 5 = radius 5 (Comst.). 

 Subcostal vein: in Diptera (Schiner), = 1st longitudinal vein (Meigen) 



= radius 1 (Comst.) : in Lepidoptera, runs from base, parallel to costa, to 



or beyond the middle, giving rise to branches which extend to the outer 



margin and thus = radius (Comst.). 

 Sub-cristate: with a moderately elevated ridge or keel on pronotum, in 



Orthoptera. 

 Subcutaneous: under the skin: applied to larvae that feed under the skin of 



animals or within the substance of a leaf. 

 Sub-dorsal: the space between the dorsum and the stigmata. 

 Sub-dorsal line: in caterpillars is to the side of the dorsal and between it 



and the lateral or, if there is an addorsal line, between that and the lateral. 

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

 dorsal row of abdominal tubercles. 



Sub-equal: similar, but not quite equal in size, form or other characters. 

 Sub-eroded: wing margins when somewhat, but irregularly, indented. 

 Sub-falcate: when a wing is only a little excavated below the apex. 

 Subfamily: a division of classification containing a group of closely allied 



genera ; different from other allied groups, yet not so as to make a family 



series : opinionative, and ending in -ince. 



Sub-fossorial: legs used in digging; yet not greatly modified. 

 Sub-frontal: close to the front; immediately behind the front margin. 

 Sub-fulcrum: a sclerite between mentum and palpiger; rarely present.
