8. Subtribe Elephantomyakia 



Elephantomyia Osten Sacken 



1859. Elephantovii/ia Osten Sacken; Proc. Acad. Xat. Sci. Philadel- 

 phia, 1859:220. 



A very distinct genus which is well-characterized by the exceed- 

 ingly elongate rostrum that is nearly as long as the entire body (Fig. 

 46, L). Other features of note lie 'in the antennae, which show the 

 beginnings of a fusion-segment involving the basal flagellar segments, 

 and with long conspicuous verticils on all segments. The venation 

 (Fig. 44, P) shows R^ entirely lacking; two branches of Rs; m-cu at 

 near midlength of the large cell 1st 31-2 and subetiiud to the distal sec- 

 tion of Cu^. The tibial spurs are short but perfectly distinct. Ihe 

 male hypopygium lias the aedeagus developed mto an elongate coiled 

 penefilum. The adult flies are not uncommon in open inesophytic 

 woods. The early .stages occur in decaying wood. In our fauna there 

 is a single species^ with a local race described at this time.
