 subtus anguste canaliculatum ; extimum coriaceum 

 penultimi trientis vel quadrantis fere longitudine, tubum 

 infra disjunctum apice attenuatum simulans, utrin- 

 que puncto spiraculiformi processuque styliformi pos- 

 tice subtus porrecto instructum, quo tubo oviductus

Tbe structure of the antennae and wing-veins, as 

 well as that of the abdomen and ovipositor, is pre- 

 cisely identical with the corresponding parts in Idarnes 

 transient, Wlk. (Idamella, Westw.) ; the tubiform seg- 

 ment, hitherto regarded as appertaining to the oviduct, 

 being followed by an overlapping segment about one-third, 

 or one-fourth, of the length of the former, open along its 

 under side and covering the base of the sheaths, which, 

 together with the terebra, usually emerge below its 

 obliquely tapering apex, though these are occasionally 

 deflexed through the channel beneath, thus leaving the 

 greater portion of this covering segment extending beyond. 

 These sheaths, closely approximated at their acuminate 

 base, and articulating within the overlapping segment at 

 about one-third of its length, are there connected with 

 the nerves which govern their action, traversing the 

 whole length of the elongate antecedent segment, and 

 further traceable therefrom, in transparent specimens, 

 through the ventral segments up to the base of the
