24 Mr. W. L. Distant’s Rhynchotal Notes. 
The Hypsoprora cassis 3, Buckt., is only a much muti- 
lated specimen of /. monstrifer, Walk. H. cassis 3 , Buckt., 
is (judging from the figure) another mutilated specimen 
belonging probably to another species. Kirkaldy, in 
giving differential characters for his proposed genus 
Gelastorrhachis, was clearly unacquainted with the type of 
Eutryonia. 
Leptocentrus thelwalli, sp. n. 
Pronotum, face, body beneath, and legs purplish black, 
more or less pale ochraceously pilose ; scutellum and lateral 
sternal areas ochraceous; tegmina subhyaline, strongly 
wrinkled, base and venation fuscous brown, apical margin 
bronzy ochraceous ; pronotum robust, convexly oblique, 
thickly somewhat finely punctate, lateral processes somewhat 
short and slender, their apices subacute, slightly backwardly 
directed, disk faintly centrally carinate, posterior process 
slender, strongly tricarinate, distinctly passing the posterior 
angle of inner tegminal margin. 
Long., incl. tegm.,7 mm.; exp. lat. pronot. process. 4 mm. 
Hab. Nyasaland (Thelwall). 
This species is to be recognized from the other Ethiopian 
members of Leptocentrus with which I am acquainted by the 
robustly raised pronotal disk and the declivous posterior 
pronotal process, which gives it the appearance of a species 
of Tricoceps, from which it is at once separated by the broad, 
short, and apically emarginate scutellum. 
Leptocentrus australis, sp. n. 
Head, pronotum, scutellum, and femora black or dark 
piceous; tibiz dark ochraceous ; a large spot at lateral 
margins of sternum, a linear spot behind the pronotal lateral 
processes, and a spot at each basal angle of the scutellum 
greyish white ; tegmina pale bronzy brown, the base reddish 
brown; pronotum strongly centrally longitudinally carinate, 
the anterior lateral processes moderately short, directed 
outwardly, their apices acute and recurved; posterior pro- 
cess tricarinate, elevated above scutellum, and then obliquely 
recurved to posterior angle of inner tegminal margin, which 
its apex a little extends beyond; pronotum and scutellum 
distinctly punctate, the apex of the latter distinctly recurved 
and elevated. 
Long., incl. tegm., 53-6 mm.; exp. lat. pronot. process. 
3-35 mm. 
Hab. South Africa (Mansell Weale). Natal; Malvern 
(G. A. K. Marshall).
