the lateral space ; the outside of this plate is also a little 

 produced, so as to form a short tooth. 



Auana ; a single female found on the 6th September, 

 1874, by Dr. Trail. 



Obs. — This species appears to be almost intermediate 

 between C. similis and C. polilus ; the less-produced hind 

 angles of the thorax readilj distinguish it from the former, 

 while from the latter it is separated by the more rounded 

 angles of the elytra and the sexual differences of the apical 

 segment in the female. The mesothoracic carina has 

 been smashed by an accident in the individual described. 



9. Coproporus inclusus, n. sp. Convexus, nitidus, 

 piceus, antennis pedibusque testaceis ; capite thoraceque 

 Ifevigatis ; elytris obsolete punctatis, angulo externo 

 obtuso; thorace basi subtruncato. Long. corp. 1^ lin. 



Antenuie yellowish, slender, rather short, a little 

 thickened towards the apex; joints 1, 2, 3, differing but 

 little from one another in length, 3rd the most slender ; 

 4th much shorter than 3rd, a little longer than the 5th ; 

 5 — 10 differing but little in length, each just a little 

 shorter and a little broader than its predecessor, 10th 

 scarcely so long as broad; 11th a little stouter than the 

 10th, and twice as long. Thorax ample, of a pitchy 

 colovu", very shining, transversely very convex, much nar- 

 rowed towards the front; hinder angles rounded; the base 

 slightly sinuate on each side near the outer angle. Elytra 

 pitchy red, about one-third longer than the greatest length 

 of the thorax ; they are very finely and indistinctly punc- 

 tured, and the outer angle is not greatly rounded. Hind 

 body reddish. Legs yellow. Mesothoracic carina not 

 much developed. 



In the female the dorsal plate of the 7th segment ends 

 in four s])ines, of which the middle ones are more slender 

 and a little longer than the outer ones ; the middle space is 

 but little narrower than the lateral one, but does not extend 

 so far towards the front; the ventral plate also ends in 

 four spines, of w'hicli the middle ones are a good deal the 

 longer ; the lateral space is rather broader than the middle 

 one, and extends more to the front ; the outer angle of this 

 plate is scarcely produced. 



In the male the dorsal plate of the 7th segment ends in 

 four short and approximate spines, of which the middle 

 ones are longer than the lateral ones ; the ventral plate of
