lilack, slender, slightly pubescent, not move than half the lenoth of the 
body ; first joint yellowish, not extending to the front of the head ; second 
extremely short; third much longer than the fourth, which is longer than 
the fifth. Thorax with a smooth pale yellow dot on each side of the fore 
part of the disk; sides pale yellow in front of the hind angles, which form 
two black long acute slightly ascending and very stout spines. Scutellum 
attenuated, extending somewhat beyond the angle of the covium, with two 
pale yellow marginal stripes, which are abbreviated near the pale yellow 
tip. Abdomen beneath with a stripe of black dots; two stout apical spines, 
which are black towards their tips. Legs luteous, slender. Fore wings 
along the costa reddish and towards the tips luteous, with a smooth pale 
yellow subcostal dot near the tip; membrane hyaline. Length of the body 
4 lines. 
In structure it resembles M. Ypsilon, the type of all of the numerous 
groups which are included in Mormidea ; some of these groups have been 
formed into genera.

Mormidea semialba. 
Albida, conferlissime et sublilissimc rufo-punclata, sublus alba; caput 
niyricante punctatum, antice quadratum ; antennce articulis 4o et 5o 
dimidio apicali piceis ; thorax antice albo marginatus, cornubus 
longis latis subrecurvis subascendentibus ; scutellum apice rotundatum 
glabrum ; membrana diaphana, striga apicali nigra. 
Whitish, oval, very thickly and minutely punctured ; punctures red ; 
under side, rostrum, antennae and legs white. Head elongate, quadrate in 
front, with blackish punctures. Eyes piceous, rather large and prominent. 
Antennae slender; second joint much longer than the third; fourth and 
fifth piceous for half the length of the tips ; fourth nearly as long as the 
second; fifth shorter. Thorax and scutellum with a whitish impunctate 
line. Thorax with a white smooth rim along each side in front of the 
horns, which are long, broad, acute, obliquely ascending and recurved. 
Scutellum attenuated towards the tip, which is rounded and smooth. Legs 
slender. Membrane of the fore wings pellucid white, with a blackish 
apical streak. Length of the body 4 lines. 
The structure of the horns of the thorax in this species distinguish it 
as the type of a group in the genus.
