158 REV. H.S. GORHAM ON NEW COLEOPTERA. [Matr. 16, 
those preceding them. Thorax about as long as wide if the projecting 
front angles are taken in, widest a little below the front ; basal 
angles right angles, sides a little sinuate not angular, front margin 
rounded and a little prominent, basal margin nearly straight ; on 
the disk, which is very even and smooth, are two large inky-black 
oblong marks a little obliquely placed, a small dot on each side 
where the thorax is widest, and one in the middle, near the base. 
Elytra pitchy, inclining to brown, the apex is yellow, and this 
colour returns some way up the suture and the margins ; they are 
convex, evenly ovate, and rounded at the apex, narrower at the base, 
and with a very obsolete sutural stria and scarcely at all widened 
margin; the epipleural fold is yellow. There is no visible 
punctuation on their surface ; but it is not glabrous as in Encymon 
angulatus, but very finely alutaceous, though the sculpture is 
hardly visible at all. 
Only two specimens of this insect have come under my notice ; 
both are males. One is in Mr. Lewis’s collection, and the other in 
Dr. Sharp’s, by whom they were obtained from Mr. Cowan. 
2. Cymones cowani. (Plate XVII. fig. 1.) 
Nigro-subviolaceus ; capite, prothorace, antennis (clava excepta) 
pedibusque rufis, abdomine rufo-piceo. Long. 63 millim. 3 Q. 
Mas. Tibiis anticis dente acuto distantemediano, apicibus intermediis 
etiam leviter incurvatis. 
Hab. Madagascar (Cowan). 
More parallel than C. sharpi, and with the thorax not so convex 
above, and more quadrate, smaller, and differently coloured. The 
head and thorax are rusty red, very little shining, and without 
punctuation; palpi red ; antennze of moderate length, and with the 
club, which is black, abrupt, and with its two first joints transversely 
heart-shaped. The thorax is transversely quadrate, with the front 
angles a little prominent, the sides a little sinuate, nearly straight, base 
obsoletely margined, and the sulcidistinct but not deep. Elytra dark 
blackish purple, their apex ferruginous, slightly shining but not bright. 
Legs in the male example pitchy, in the female clear rusty red. 
Although this species and the following one differ in several 
particulars of their structure from C. sharpi, I have not been able 
to find any characters of sufficient importance to warrant their 
separation generically. In the abruptly formed club of the antennze 
and in the form of the thorax these two species are nearer to 
Encymon, but the strongly toothed tibiz in the male, and the form 
of the body, less swollen, and with its sides more parallel than in any 
eastern species of that genus, indicate a radical divergence from that 
type. 
Only two specimens have come under my notice; they were 
obligingly placed in my hands by Dr. Sharp for description. 
3. CyMONES HELOPIOIDES. (Plate XVII. fig. 3, ¢.) 
Niger ; parum nitidus ; prothorace transversim quadrato, cum elytris 
subopacis. Long. 64-7 millim. 3S.
