494 INSECTA MADERENSIA. 



brownish-piceous, with the sides shghtly rounded (the broadest part being abowt the middle) ; 

 the punctures large and rather rugose, and with a slight tendency to be disposed in rows ; and 

 with the margin a little prominent and roughened at the humeral angles. Antenna and legs 

 (especially the latter) of a brighter colour than the rest of the insect, — being generally rufo- 

 ferruginous. 



A common insect throughout Madeira at low elevations ; especially towards the 

 southern coast, — occurring in grassy spots, beneath stones, on most of the sunny 

 slopes facing the sea. It appears to be more particularly abundant from the 

 autumn to the following spring. I have taken it in profusion along the cliffs to 

 the eastward of Funchal, as far as the Cabo Gcrajao, in October and Xorember ; 

 in the Rev. R. T. Lowe's garden, at the Levada, in Febru.ary ; at the Praya For- 

 moza, and on the Pico do Cardo, in March and April ; as also m Porto Santo at 

 the beginning of May. It delights in the hottest aspects, secreting itself under 

 loose scoriae, — from which, owing to the ramifications and hollows with which 

 they are perforated, and into which it suddenly retreats on being exposed to the 

 light, it is not always easy to extricate it.

The genus Calcar presents abundant points of singularity which will serve to 

 distinguish it from the neighbouring groups, — its narrow, shining body and elon- 

 gated prothorax (which, unlike that of Tenehrio, has the angles, especially the 

 basal ones, olituse or rounded off), in conjimction with its slightly cm-ved four 

 anterior tibiye, and the blunt tooth in the centre of the inner margin of its hinder
