Antennae (fig. 3, b, c). The pedicel though compressed is almost normal, and the 

 club is much more distinct from the funicle than in either E. pattersoni or 

 E. italicum. 



Thorax. Reticulation of the mid lobe as coarse as that of the scutellum generally 

 and coarser along the mid line. Bristles much fewer than in pattersoni {e.g., in 

 front of the suture there are in pattersoni about 12, in cornigerum about 6 bristles) ; 

 on the scutellum also the bristles are fewer (about 7 or 8 on each side of the mid- 

 line, 20 : 20 in pattersoni) and the sensory pustules are at one-third from the hind

edge. On each side of these pustules the apical one-third of the scutellum is 

 smoother with, under a moderate power (up to X80), a number of minute black 

 dots surrounded by a more shiny area ; when rendered transparent, moimted in 

 balsam, and highly magnified these dots appear to be the external openings of tube- 

 like sensory (?) structures (30-40 in all). Each structure lies at the angle of a cell 

 in the reticulation and stretches forward anteriorly through the chitin. No sensory 

 bristles are however visible, even with a magnification of over 600. Besides the 

 bristles already noted, there are two longer, stouter ones apically in the middle (1, 1). 

 Metanotum in two triangular portions each of which shows anteromedianly 

 3-4 very short longitudinal rugae and about the same number transversely
