90 'My. D. Slia^^ Contrihutioiis to the 



Antennae moderately Ions; and slender, blackish in 

 colour, with the three basal joints yellowish ; 3rd joint 

 nearly equal to 2nd in length, 4th slender; 4 — 10 each 

 slightly shorter and broader than its predecessor, so that 

 the 10th is a little transverse; 11th rather long. Head 

 pitchy, shining and impunctatc ; palpi yellow. Thorax 

 with the hind angles only moderately rounded ; the base 

 slightly sinuate on each side, shining and impunctatc, 

 reddish with the disc broadly pitchy. Elytra dark red- 

 dish, ample, very finely punctured and reticulated, the 

 hind angle not much rounded. Legs slender, red. 

 Mesosternal carina only a little elevated. 



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

 four rather broad sharp teeth, of which the middle ones 

 project much farther backwards than the side ones ; the 

 space separating the middle teeth is not broad, and does 

 not extend far forwards ; the base of the lateral notch is 

 much nearer to the front. The ventral plate bears a large 

 deep notch, the sides of which are a little sinuate, and the 

 lateral angles acuminate and a little produced. 



A single male was taken by Dr. Trail on the 5th 

 November, 1874, but I have no record of the exact 

 locality. 



Obs. — Though extremely similar to C. cognatus, I be- 

 lieve this will prove to be a distinct species; it is slightly 

 narrower, and not quite so convex ; the hind angle of the 

 elytron is a little less rounded, and the spines on the 7th 

 segment in the male are a little longer, and the notch on 

 the ventral plate is a little deeper. 



12. Coproporus rufescens, n. sp. Rufo-testaceus, niti- 

 dus, glaber, transversim sat convexus, elytris marginem 

 latcralem versus late profundeque impi-essis, angulo extemo 

 minus rotundato. Long. corp. 1^ lin. 



Entirely of a reddish colour and impimctate, except 

 that on the elytra are traces of a sparing and very obsolete 

 punctuation. Antennte a little thickened towards the 

 apex; 3rd joint small; 4 — 10 differ but little in length, 

 each just a little broader than its predecessor, 10th 

 scarcely so long as broad ; 1 1th nearly twice as long as the 

 10th. Thorax ample, as broad as the elytra, narrowed 

 to the front, the hind angles rather obtuse and a little 

 rounded ; the base nearly truncate, being very little pro- 

 duced near the external angles. Elytra one-third longer
