FAM. CICADIDiE i3 



length about equal to that of pronotum; pronotum a little shorter than mesonotum, its lateral margins 

 convex anteriorly and concavely sinuate before posterior angles, which are ampliated; abdomen much 

 longer than space between apex of head and base of cruciform elevation, its lateral areas obliquely 

 depressed above; beneath with the disk somewhat flat and the marginal areas obliquely directed 

 upward; tympanal flaps shorter, but not narrower than tympanal cavities; opercula transverse and just 

 passing base of abdomen ; anterior femora strongly spined beneath near apex ; anterior tibiae longer 

 than femora, anterior tarsi more than half the length of tibiag; tegmina and wings long and narrow', 

 greatest width of the first only equal to a third of length, its basal cell much longer than broad, fourth 

 ulnar area much compressed at base of third, apical areas eight.

Incertae sedis 



65. Genus TRIGLENA, Fieber 



Triglena. Fieber, Rev. Mag. Zool. (1876), p. 23; Distant, Syn. Cat. Horn. (1) Cicad. p. 84 (iqo6); 

 Horvath, Ann. Mus. Hist. Nat. Hung. (1912), p. 604. 



Characters. — This genus, without the examination of the type, or a typical specimen (which 

 so far as I am aware or can learn, no entomologist knows) is insufficiately described b)' its respected 

 founder. Horvath rightly fastens on its principal points « Elytris areis apicalibus septem — alis areis 

 apicalibus tribus instructis », but he places it with genera which I think may probably prove to be not 

 its closest allies.

Division FIDICINARIA 



Fidicinaria. Distant, Ann. Mag. Nat. Hist. (7). Vol. i5, p. 3io (iqo5). 



Characters. — This division is represented by a series of Neotropical genera, in all of which 

 the tympanal orifices are more or less exposed; the tympanal flaps are always well developed and are 

 usually somewhat angulate at their apices; the tegmina and wings are hyaline, sometimes maculate, but 

 never opaque, and they always possess eight apical areas; the lateral margins of the pronotum have 

 sometimes their posterior angles lobately produced, but they are never convexly ampliate nor 

 medially angulate. 



The Fidicinaria are composed of Neotropical genera of which some species are found in the 

 Southern Nearctic Region.
