1944 ] Three New African Species of Mordellid Beetles 9 
with a concave, elongate depression between the edges. Head 
strongly flattened antero-posteriorly, front, clypeus, and vertex 
forming a straight line. Eyes reaching occiput. 
Pronotum distinctly broader than long (2.0 X 1.8 mm.), an- 
terior margin and sides rounded, base arcuate, midbasal lobe 
short, broad, subtruncate. Scutellum subquadrate, sides but 
slightly angular, apical margin truncate. 
Elytra short, but four-tenths longer than broad (3.2 X 2.0 
mm.), sides attenuate to apex, apices individually rounded. 
Anal style short, thick, truncate at apex, but one-half longer than 
hypopygium (1.5 X 1.0 mm.). Posterior tarsal claws with five 
teeth, two premedian, the first very small, the other distinct; 
three postmedian, first larger than any other except terminal one, 
second small, third terminal. 
(cf) . The males are darker, the castaneous parts of the female 
being almost piceous in this sex. The elytral markings are more 
restricted, the posterior band being curved anteriorly at the 
suture and lateral margins. 
Length: to apices of elytra, 3.3-5 mm.; to tip of anal style, 
4. 3-6. 5 mm. 
Five specimens: male type and two male paratypes, Wady 
Madu, N. E. Darfur, July 25, 1930, at flowers of Premna resinosa 
(Michelmore) ; one male paratype, Plain below J. Kaboija, J. 
Midob, N. E. Darfur, August 7, 1930, common on leaves and 
flowers of large succulent grasses (Michelmore) ; one female para- 
type, Duani, wilderness of Toganoy, N. E. Darfur, August 12, 
1930, on foliage of Grewia flavescens (Michelmore). 
This species may easily be separated from the only other Afri- 
can member of the genus, T. robusta Pic (Rev. zool. bot. afr. 21, 
1931, p. 45), by the wholly different pubescent markings, the 
unicolored abdomen and legs, the bicolored antennae, and the 
larger size. Mr. Pic’s short diagnosis unfortunately does not 
permit a more adequate comparison. 
Mordellistena sudaniensis new species 
Form elongate, sides subparallel, derm generally black, with 
the following exceptions: anterior and intermediate legs, front, 
palpi, and three basal antennal segments flavocastaneous ; pos- 
terior legs fuscocastaneous. Body densely covered with fine, 
recumbent, cinereous pubescence and minute, closely-placed 
tubercles.
