Antennal grooves: see a. fcssa. 



Antennal lobes: of brain, see deuto-cerebrum. 



Antennal organs: in Collembola are sensory structures on the distal segment. 



Antennal process: Diptera; the frontal protuberance upon which the antennae 

 are inserted. 



Antennal sclerite: see annulus antennalis. 



Antennal segment: the second or deutocerebral segment of head. 



Antennary fossa: see antennal fossa. 



Antennary furrow: in Mallophaga, grooves on the under side of the head in 

 which the antennas lie. 



Antenniferous: bearing antennae. 



Antenniform: made up like, or having the appearance of antennae. 



Antennule: a small antenna or feeler-like process. 



Antenodal cells: Odonata; in Agrionidce the cells included between the short 

 sector (M 4 Comst.) and the upper sector of the triangle (Cu i, Comst.), 

 and between the quadrilateral (or quadrangle) and the vein descending 

 from the nodus. 



Antenodal cross veins: Odonata; extend between costa and sub-costa. and 

 between sub-costa and media, from the base to the nodus, forming the ante- 

 nodal or ante-cubital cells : =: ante-cubital. 



Antenodal costal spaces: Odonata; the cells between costa and sub-costa, 

 from the base to the nodus : = ante-cubitals. 



Anteocular: the region just before the eye; specifically applied in Collembola 

 to a peculiar structure of undefined function situated in front of the eyes : 

 = prostemmatic. 



Antepectus: the lower surface of the prothorax. 



Antepenultimate: the last but two. 



Anterior: in front; before; in Dip., that face of the leg which is visible from 

 the front when the leg is laterally extended and bristles on that face are 

 anterior. 



Anterior branch of third vein, in Diptera (Will.), = radius 4 (Comst.). 



Anterior field: Orthoptera ; of tegmina, see costal field. 



Anterior intercalary vein: Diptera; ^ media 2 (Comst.); of Loew = disc- 

 oidal vein. 



Anterior lamina: Odonata; the anterior sternal border of abdominal segment 

 2. modified to form the front margin of the genital pocket. 



Anterior lobe: Orthoptera; see lobes. 



Anterior squama: = antisquama : q. v. 



Anterior stigmata! tubercle: on thoracic and abdominal segment of cater- 

 pillars ; varies from substigmatal to stigmatal anterior ; sometimes united to 

 IV: it is V of the abdominal series, IV of the thorax (Dyar). 



Anterior trapezoidal tubercle: on thoracic and abdominal segment of cater- 

 pillars ; addorsal, anterior, always present, rarely united with II : it is I of 

 the abdominal series, la of the thorax (Dyar). 



Antero: to the front; anteriorly. 



Antero-dorsal: Diptera; applied to leg bristles at the meeting of anterior and 

 dorsal face.
