CAXARIAN COLEOPTERA. 3 



4. Nebria currax, n. sp, 



N. nigra, angustiila, nitida ; prothorace subcordato, ad latera anguste 

 explanato et paiilo reflexo, antice sat profimde emarginato, an- 

 gulis anticis sat porrectis ; elytris ovalibus, striatis, stria tertia in 

 singulo punctis circa quatiior aucta ; palpis, antennis (articnlis 

 tertio quartoque obscurioribus exceptis) tarsisque ferrugineis, 

 femoribus tibiisque piceis. — Long. corp. lin. 5|. 



Habitat Canariam Grandem ; inter lapides juxta rivulnm prope 

 oppidum Teror mense Aprili a.d. 1858 duo specimina deprehendi. 



The only two examples of this very rare and distinct Nehria which 

 I have hitherto seen were captured by myself among-st the wet stones 

 and rubbish of a small stream, in the island of Grand Canary, which 

 joins the little river at Teror, within half a mile of the town — 

 during my residence there, with the Rev. R. T. Lowe, in April 1858. 

 It belongs to the same type as the N. dilatata ; but its narrower 

 outline, less elliptic, brighter elytra (the strife of which are less per- 

 ceptibly crenulated), rather smaller size and darker hue, in con- 

 junction with its less widely margined and less deeply excavated 

 pro thorax, will (apart from other differences) at once separate it 

 from that insect.

Indagator, Fab., Mant. Ins. i. 197 (1787).

Habitat in Canaria, Teneriffa et Palma, passim. 



Although not the older of the two, I have preferred the name of 

 indagator for the present Calosoma to that of Maderce, since it is the 

 one under which the insect is almost universally known, and since 

 the author of them both is the same. In this particular instance it 

 would seem better not to retain the specific title of Maderce ; for the 

 insect is widely spread over Mediterranean latitudes (being by no 

 means peculiar to Madeira), and is usually recognized as the C. in- 

 dagatot. It is out of deference to the opinion of my friend Dr. Schaum 

 that I have thought it desirable to make this slight change ; for it 

 will be seen, on reference to my ' Ins. Mad.,' that I adhered in that 

 volume strictly to priority, and quoted the species by the name (irre- 

 spective of its a2ipropriateness) under which it was first published by
