elytra) being rather straightened — thus forming a tolerably defined 

 angle with each of the striae which it connects, — by merely the pos- 

 terior half of its elytra being finely (and somewhat sparingly) punc- 

 tured, by its front tibiae being armed externally with a row of short 

 and small spinules (as in the S. cJialcites), whilst the four hinder ones 

 are studded (particularly towards their extremities) with long spinose 

 cilia, and by its anterior spurs being apparently almost obsolete. 



The only four examples which I have seen of this minute Scqrrimm 

 were captured by myself in the low ground immediately outside 

 Arrecife, in Lanzarote.

The present Sapriims may be known by its greenish-black hue 

 (which has also a just perceptible aenesceut tinge), by the very close 

 and rather deep punctures on the hinder half of its elytra, by its frontal 

 keel being straight, and its forehead very irregularly scrtftroso-strigu- 

 lose anteriorly, by the third and fourth " dorsal " striae of its elytra 

 being usually much shorter than the first and second, and by its four 

 hinder tibiae being rather thickly studded with exceedingly long seti- 

 form spinules, and with their apical spurs (though somewhat slender) 

 considerably developed. It is nearly allied to the European S. metal- 

 licus. Its prothorax, however, is relatively a little larger than is the 

 case in that insect ; its elytra are more densely punctured behind and 

 have their striae very much shorter — the two inner dorsal ones being 

 exceedingly abbre-vdated, and the outer (or first) one, which is greatly
