INSECTA MADERENSIA. 15 



The present genus contains insects of a large size, most of which are more or less 

 brilliantly ornamented with metallic tints ; which even in the black species are 

 scarcely ever altogether absent, being there replaced by minute golden punctm-es, 

 or lines. The only representative which the Madeira Islands possess belongs to 

 this latter division. The Calosoniata are exceedingly voracious ; and may be often 

 observed either crawling rapidly over the ground in grassy spots, or else mounting 

 the trunks and branches of trees, where they can obtain with greater facility the 

 smaller insects and larvae on which they subsist. It is one of the most mdely 

 distributed genera in the world ; nevertheless the species composing it are not so 

 numerous as might be expected. North and South America, the "West Indian 

 Islands, the Cape of Good Hope, the western coast of Africa, China, Siberia, and 

 even the little island of St. Helena, have however each of them, like Em'ope, their 

 peculiar forms. The Madeu-an species is found thi'oughout central and southern 

 Europe, but is nowhere abundant ; nevertheless it would seem to be commoner in 

 Mediterranean latitudes than elsewhere. It occurs likcAvise in the Canarian 

 Group.

Habitat in montibus JIaderee Portusque Saucti, sestate et autumno frequens : ad Eibeiro Frio per 

 plures annos copiosissime colligebat Rev. Dom. Lowe ; atque etiam a Cabo Gerajao prope Funcbal 

 cl. Dom. Heer, Turici, mibi nuper communicavit. 



C. black, veiy slightly shining. Head and prothor ax rather roughly punctiu-ed ; the latter short and 

 small, regidarly rounded at the sides, and with a very obscure longitudinal channel which vanishes 

 in front. Elytra finely striated, the strise usually punctui-ed, but both punctures and striae occa- 

 sionally almost obsolete ; the interstices with minute, transverse, curved reticulations, having 

 much the appearance of imbricated scales ; with three rows of bright golden or greenish im- 

 pressed points. Four hinder tibice long and sUghtly curved*, the anterior ones short and robust. 



The Carabus Maderce and Carabus Indagator, both of Fabricius, are unquestion- 



* It seems to have been overlooked by Dejeau, as well as by the other uatiu-alists who have described 

 the present msect, that it is not merely the intermediate tibis which are ciun-ed, but the hinder ones also.
