The length and slenderness of the antenne, with the 
spotted wings, render this insect extraordinary. The 
large rounded tubercle on the front part of the head 
appears to be natural. The antenne appear to be only 
5-jointed; the third joint is thrice the length of the head 
and first joint of the antenne, the terminal joint being 
six times longer than the preceding joint; they are 
extremely slender and very finely setose; the palpi are 
not longer than the head; the tibie are armed at the 
tip with a distinct acute spur; and the abdomen is 
terminated by two horny elongated recurved appendages, 
each with a short curved very acute spine. The second 
longitudinal vein emits close to its base a short spur into 
the disc of the wing, and the discal cell is nearly square, 
and emits three equal veinlets at its outer margin. 
I am indebted to the Baron Osten-Sacken for the 
following notes on this genus :— 
“This genus is closely allied to Anisomera, and, like 
the latter, easily distinguished from all the Tipulide by 
the abnormal number of antennal joints: usually six in 
the male,* and about ten in the female. Lriocere are 
numerously represented in the tropical regions of the 
Old, and of the New, World. In North America 
they are not rare in the temperate, and even in the 
colder region, and reach as far north as Canada. In 
Europe they are much more rare, and are represented by 
two species only (genus Penthoptera, Schiner), which 
occur, as far as I know, only in the south and south-east 
* “No wonder that you do not perceive any articulations but 
two in the long extremity of the antenna of this species. This 
species should have six joints in the antenna; you make out five, 
but it may be that the last joint is rudimental.’’-—Osten-Sacken, 
in. litt., July 24th, 1880.
