168 Rev. F. D. Mo rice on the 6th $ ventral segment 



he has fully described its external characters, I will only 

 add a figure of the antenna (Fig. 25) to show its curious 

 dilatations and hook-like apex. 



Fig. 6. Main lobes rounded with rather widely truncated 

 apices, and densely hairy (yet with hardly any definite 

 central pencil). Their margins, as also those of the two 

 next species, run very diagonally, embracing an almost 

 equilaterally triangular space in which lies the basal 

 portion of the process, nearly filling it. 



The process has a distinct narrow petiole, from which 

 proceed two gradually widening pilose plume-like lobes, 

 their outer margins running parallel to the sides of the 

 triangular gap above mentioned, and almost touching 

 them ; their inner margins are separated by a long narrow 

 and linear gap till near the apex, where the lobes are 

 rounded off and the gap between them widens. The 

 greatest width of the lobes (a little before their apices) 

 measures about § of their greatest length. 



The species is common in the Mediterranean regions : 

 I have taken it in France, Italy, Switzerland, Austria 

 and Algeria. Ducke calls it spinolm, Schenck. ; but as 

 he does not consider it to be the spinolm of Lepelletier, 

 and as it is generally admitted to be the ctementaria of 

 Gerstsecker, under which name it has frequently been 

 referred to by well-known writers, I prefer to follow 

 Schmiedeknecht and call it emmentaria, Gerst. The insect 

 being well known, I will here only mention that in the 

 $ the apical ventral segment is not, as in adunca and 

 moraivitzi, Perez, produced spinosely at the apex. 



Fig. 7. The main lobes differ from those of cmmcntciria 

 in being hardly truncate but almost angled (roundly how- 

 ever) at their apices. 



The process is very like that of emmentaona, but does 

 not so nearly fill the triangular gap containing it. The 

 lobes are much narrower (quite three times as long as 

 broad), they spring from a longer petiole (which removes 

 their inferior margins from the main lobes, while in 

 csementaria these almost touch each other), they widen 

 comparatively little towards their apices, so that the 

 division between them is wider and more triangular, 

 giving them the appearance of being more divergent. 



This species I take to be Zepclleticri, Perez. It com- 

 pletely suits his description (5th ventral segment "trisinue," 

 comparatively simple antennae, etc.). I have taken it
