264 ENTOMOLOGICAL NEWS. [June, ’12 
Having recently had an opportunity to examine a_ topo- 
typic female specimen of Karsch’s T. gnu, I find the Luebo in- 
dividuals to be quite distinct, the female sex of the new form 
differing in the characters previously noted (vide supra) and 
also in the strongly compressed frontal costa, the margins of 
which are contiguous through nearly their entire length. 
The female which we have associated with the male type 
shows some affinity with T. quagga Karsch and T. depressi- 
frons Bolivar, both known only from the female sex, but the 
coloration, which is of great importance in the Eumastacine, 
shows a number of differences. 
é Size small; form distinctly compressed; surface of dorsum of 
thoracic and proximal abdominal segments finely rugulose. 
Head with the dorsum considerably elevated dorsad of that of the 
pronotum, when seen from the side subobtuseangulate at the highest 
portion of the eyes, fastigium decidely declivent, rounding into the de- 
cidedly retreating facial line, the latter slightly concave; occiput with 
distinct median and strongly divergent lateral carinz, the lateral ones 
contiguous between the eyes and passing into the almost entirely con- 
tiguous carine of the frontal costa, the latter very slightly separated 
for a short distance on the fastigium; antenne but little longer than 
the depth of the eye; eyes very large, moderately prominent. 
Pronotum with the dorsal carina distinct but not elevated; lateral 
lobes of pronotum about as deep as long, cephalic margin strongly 
arcuate ventrad, ventro-cephalic angle obtuse, ventral margin arcuato- 
emarginate cephalad, ventro-caudal angle slightly produced, well 
rounded. 
Proximal abdominal segments cari- 
nate; apex of abdomen strongly re- 
curved, subinflated; supra-anal plate 
with a pair of mesially constricted 
carine, apex subtruncate; cerci elon- 
gate, styliform, apex blunted; distal 
ventral abdominal segment bullate, 
the outline regularly arcuate when 
seen from the side; subgenital plate 
elongate, sub-cylindrical, the apical 
margin slightly produced laterad and 
regularly arcuate in shape, when seen 
from the side distinctly depressed
