134: AMERICAN ENTOMOLOGY. 



Dorsal, of the back. 



Dorsum, the posterior portion of the sfethidium on the superior 

 surface of the body, directly above the postpectus, and bounded 

 behind by the tergum; in the Coleoptera it is covered by the 

 basal portion of the elytra. 



Duplicate, doubled. 



E. 



Ecalcarate, without a spur or horn. 



Echinate, set with prickles. 



Edentulous, destitute of teeth. 



Edge, of a surface, is that line which includes the margin, and 

 forms the extreme boundary ; the elytra of many Coleoptera 

 have a deflected margin beneath the edge called epipleura. 



Eflected, bent outwards somewhat angularly. 



Egg, the first state of the insect. \ 



Elliptical, elongate-oval ; differs from oval by having the lines 

 nearly parallel in the middle. 



Elytra, coriaceous, opake, more or less solid lamellae, separated 

 in repose by a rectilinear suture, substituted for the anterior 

 wings and covering the dorsum and tergum in repose ; in- 

 cluding base, tip, humerus, and epipleura. See hemeli/tra. 



Emarginate, notched; terminating in an acute notch at tip. 

 See sinuate. 



Ensifurm, sword-shaped; two-edged, large at base, and tapering 

 towards the point. See ancipital. 



Entire, (wings) with a simple margin ; not indented on the edge. 



Epuptillate, an ocellate spot included by a colored ring, but desti- 

 tute of a pupil or central dot. 



Epipleura, the deflexed or inflexed margin of the elytra, imme- 

 diately beneath the edge. 



Equal, superfices without inequalities, not canaliculated, striated, 

 punctured, &c. ; this term differs from plane, in not requiring 

 the part to be level or in a rectilinear direction, but occurs in 

 round bodies ; also applied to bodies of the same length. 



Equitant, folded one upon the other; laminated. 



Erect, upright ; nearly but not absolutely perpendicular to the 

 horizon. See vertical. 



Eroded, gnawed ; as if worm-eaten ; (edge) with irregular teeth 

 and emare-inations.
