middle than at the sides, so that viewed from in front it appears 
only slightly emarginate; its size is much smaller (long., 84—11 1.); 
its prothorax has only one excavation (a very large one) and only 
one tubercle (which is of the form of a short horn); its scutellum 
is levigate except near the front where it is finely and closely 
rugulose ; its elytral puncturation is a little finer and much less 
plentiful, the first interstice bearing only sparse confused punc- 
tures, the interstice between the first and second pairs of rows of 
punctures only’a more or less interrupted row of fine punctures, 
and that between the second and third pairs only fine punctures 
usually disposed in a more or less interrupted row; the pygidium 
is devoid or nearly so of fine puncturation ; the space in front of 
the furrow on the apical ventral segment is in the female almost 
without punctures or (in some examples) very sparingly punc- 
tulate ; the apical dilatation of the front tibiz of the male is not 
bisinuate externally. 
C. pygmeus, sp. nov. Fem. Sat late subovatus; C. bifosso 
affinis; differt statura multo minore; prothorace multo magis 
sparsim punctulato, excavatione et tuberculo unicis instructo, 
ad basin haud marginato ; elytrorum interstitio 1° sparsim, 
2° 3° que uniseriatim, ypunctulatis; pygidio puncturis 
minutis haud impresso; cetera ut C. bifossius. Tiong., 74 1.;

I have ventured to describe this female because T have before 
me also a male (belonging to Mr. Lea) which however is slightly 
deformed I think and therefore not suitable to be regarded as a 
type; its elytra bear some unsymmetrical gibbosities which look 
as if caused accidentally, probably in the pupal condition. I can 
say however that it presents all the characters noted above as 
distinguishing the female from C. bifossus, also that the apical 
dilatation of its front tibiz is not hisinuate externally. 
This species differs from all those mentioned above in the 
extremely sparse puncturation of its prothorax on which (except 
near the front and lateral margins) the intervals from puncture 
to puncture are for the most part about three or four times the 
diameter of a puncture. It also differs in the base of its pro- 
thorax unmargined except close to the hind angles. In the 
female the space on the apical ventral segment in front of the 
furrow is almost without punctures. The pygidium of the male 
example is notably Jess closely punctulate than that of the female 
and of C. bifossus.

NV. bidentatus, Blackb. In a recent re-examination of the 
Dynastides in my collection I observed with regret that this 
species is a Xynedria and that I was in error in describing it as
