from the Island of Johanna. 
the scutellum is invisible. From Barystethus it differs in 
having the thorax not narrowed anteriorly, the spongy part of 
the club of the antenna} scarcely at all visible, the pygidium 
deflexed and not transverse. From Diathetes it differs in 
having the scutellum entirely concealed; and I do not discern 
any grooves in the tibia} as described by Mr. Pascoe. 
7. Perissoderes rufcollis , sp. n. 
Niger, opacus; thorace quadrato, rufo, discrete punetato, margine 
antico nigro, basi media acute producta; elytris thorace parum 
latioribus, postico angustatis, subtiliter striatis, striis punctis 
distantibus, interstitiis planis, uniseriatim punctatis. 
Long, (rostr. excl.) 3^ lin. 
Rostrum stout, as long as the thorax, rather strongly and 
closely punctured at the sides of the base, finely punctured 
above. Thorax dull rusty red, not very closely or distinctly 
punctured (although the punctures are not small), as long as 
broad, suddenly narrowed in front, a trifle broader before the 
posterior angles than before the anterior constriction, the sides 
subparallel, obtusely rounded anteriorly, slightly sinuate in 
the middle, the base bisinuate, the mesial lobe produced over 
the scutellum, acute at its apex. Elytra at the base a little 
broader than the thorax, and not quite one third longer, 
gently narrowed posteriorly ; the stria} are very fine, and are 
interrupted by distinct punctures, which are placed rather far 
apart; the interstices are flat and furnished with a single 
regular line of distinct punctures, which are about twice as 
close together as those on the stria}. Pygidium closely and 
strongly punctured. Femora strongly punctured ; tibiae with 
finer punctures arranged in lines. 
8. Sternotomis cornutor , Fabr. 
Two examples. This species was originally described by 
Fabricius as coming from America. It has since been re¬ 
corded (under the name S. comes) by Prof. Westwood, with 
doubt, as coming from Madagascar. 
See note on the locality and synonyms of this species, Ann. 
& Mag. Nat. Hist. 1878, i. p. 424. 
9. Praonetha ohsoleta , Fairm. 
A single example which agrees very fairly witli the descrip¬ 
tion of this species.
