of a Catasarcus. The second joint of the funicle considerably longer than the first 
is a well-marked character. I cannot say confidently wliere this species would fall 
in Mr. Pascoe’s table of (Tr.E.S., 1870), for I am unable to arrange the 
species of the genus in Mr. Pascoe’s groups, where a main distinction consists in 
the species being (a) moderately or {b) strongly “ convex above.” If this species 
is regarded as “moderately” convex above it must be near opimns if “strongly,” 
it is probably near effloratus. I am not sure that I know either of those species, 
but the present insect is clearly distinct from both.

brunnea setis minus brevibus nigris intermixtis vestitus, pedibus vix rufescentibus; 
capite vix manifeste punctulato ; rostro brevi quam caput angustiori, ad apicem 
emarginato, cariuis externis antrorsum parum divergentibus internis vix deter-

transversis ; prothorace vix transverse, minus confertim tuberculato, antice c^uam 
trails basin vix angustiori, lateribus minus arcuatis ante medium vix dilatatis, 
latitudine majori vix ante medium posita ; elytris sat convexis, leviter 3-costatis,

I am unable to specify any previously-described Talanrinus with which this 
species can be usefully compared on account of its elytra being (when carefully 
observed) distinctly (and from a certain point of view very noticeably) 3-costate, 
and yet very differently so from any of the species known to me of those which 
Sir W. Macleay places in his group of Talaurini costati, for the suture is not 
costate and the three costie are all very much feebler than in {e.g.) hiscipemiis^ 
Mad., and Mastersi, Mad. It may be recognised by its very .stout antennal 
(resembling those of T. typicus, Mad.) and the black colour and unusual length of 
the setaj of its upper surface. The sculpture of its elytra also is decidedly 
characteristic in the absence of any protuberances large enough to be called
