Mr. A. Murray on Coleoptera from Old Calabar. 21 
Pale chestnut or testaceo-ferruginous in colour, with tip of the 
mandibles black; shining, finely punctate. The head rather 
broad, with a marginal projection in front of the eye; the cly- 
peus lower than the rest of the head, and also separated from it 
by a further depression ; there is a very shallow depression on 
each side, between the eyes, which are rather strongly granular; 
punctuation fine. Thorax nearly a third broader than long, 
smooth and flat, with shallow depressions towards the posterior 
angles; sides parallel; apex truncate; anterior angles, as seen 
from above, right-angled, posterior rounded except at the 
angle of the base, where there is a slight projection; base and 
sides margined, the margin visible from above at the posterior 
half of the thorax, not visible on the anterior half, it being 
turned in below. Scutellum small, transversely ovate, rounded ; 
the apex slightly indicated, very slightly punctate. LElytra 
punctate-striate, the strie becoming evanescent towards the 
apex, the interstices punctate ; shoulders not prominent, sides 
subparallel; slightly narrower behind the shoulders, and becom- 
ing broader again behind the middle ; apex rotundato-truncate, 
sides margined, but the margins not seen from above. Under- 
side very shining and smooth, more finely punctate than above. 
I have only received one specimen of this species; and even it 
was somewhat imperfect, the posterior tarsi having been lost ; 
but it appeared such an interesting addition to the genera of 
Cucujide that I have had no hesitation in describing it from my 
materials such as they are. 
The only forms which we have hitherto known of this little 
family are the true Cucujus, with its dull opaque texture and 
usually bright-red colour, of which species occur in Europe, 
America, and Australia. In looking at the section from my pres 
sent point of view, the Australian Platisus clearly goes along 
with the typical Cucujus. The Brazilian Palestes, bright and 
shining, forms a different section ; and the present genus a third. 
It has a certain degree of superficial resemblance to Trogosita.
