The female of sitlcatitni is further defined in a brief key to 

 the known females following the description of E. concisnni. 

 Specimens of snlcatnm have been studied by Dr. Calvert and 

 in his opinion the species is distinct. 



Enailagma concisum new species (PL VI, Figs. 6-10). 



<J . Superior appendage in profile view with the apical margin about 

 two-thirds as long as the inferior margin, oblique, nearly straight, and 

 not bilobed but with the inferior apical angle of the intero-inferior 

 lamella slightly enlarged. In dorsal view the intero-inferior lamella 

 reaches the level or nearly the level of the supero-internal subapical 

 hook but the dorso-apical portion of the intero-inferior lamella is 

 produced obliquely apically to fuse with the externo-superior branch 

 of the appendage, so the distinction between the externo-superior 

 branch and the intero-inferior lamella is not well marked in the sub- 

 apical part of the appendage as it is in corresponding parts of pictuin. 

 Th.'s results from the greater length of the externo-superior branch 

 of the appendage in concisum as compared with pictuin, and it is in 

 concisum that the supero-internal subapical tooth is relatively more 

 apical and therefore more reduced. 



Nasus orange, a transverse basal black stripe and on either side, at 

 mid-length, a small brown to black depression. 



Frons : pale color of its anterior surface on either side reaching 

 the level of the median ocellus, but the latter is bordered in front 

 with a small pale area of varying size and an anteriorly projecting 

 quadrangle of black, the latter often unsymmetrical, and in one case 

 broken, so the small yellow area in front of and adjacent to the median 

 ocellus is joined on one side with the anterior orange color of the frons. 



Pale postocular spots linear cuneiform, widely separated by black from 

 the pale color on the rear of the head below. 



Prothorax shining greenish black, front and hind lobes broadly 

 edged with orange; and sides of middle lobe paler orange; dorsum of 

 middle lobe with a round orange spot, varying greatly in size on 

 either side, and with a median orange geminate spot of varying sixe. 

 1 resent or wanting. 



Width of black middorsal thoracic stripe about .67, of pale ante- 

 humeral about .33, of black humeral about .43 mm. 



Second lateral suture with a black stripe its entire length, widening 

 posteriorly from a narrow line at its anterior end. 



Abdominal segment 9 orange on the sides below, dorsum black 

 except the apical membranous ring which is orange. 



9 . Mesostigmal lamina largely pale, the upper half, anterior to 

 the pale vertical posterior inflated carina, and a very narrow border, 

 posterior to this carina, black. 



The merest prominence and no trace of a tubercle on the antero- 

 mesal angle of the pale antehumeral stripe.
