14 INSECTA MADERENSIA. 



Unlike Scarites, the species are extremely active, running with the utmost velocity. 

 They are very voracious, and reside principally l)eneath stones in moist spots. In 

 the south of Europe they are usually taken at the edges of rivers and streams, Imt 

 the only specimen wliich I have myself captured in the Madeu'a Islands was in a 

 decidedly di'y locality.

Habitat sub lapidibiis pvope urbem Fuuchalensem Maderse, rarior : species a meipso semel tantuBi, ad 

 Praya Formoza d. 8 Mai. a.d. 1818, rcperta ; sed nupcr ad oram niaritimam juxta Gorgulho 

 Januario ineunte el. Dom. Hear, Turici, detexit. 



A. rufo-testaceous, ^•cl•y pubescent. Head and prothorax exceedingly shining ; the former narrow ; 

 the latter small and globose, constricted behind, and with a slight dorsal channel which is more 

 particularly apparent in front. Elytra somewhat cylindrical, regularly and deeply punctate- 

 striated. Antenna dusky testaceous. Legs long, and very pale. 



Apparently rare. The only specimen which I have myself liitherto captm-cd was 

 from beneath a stone, on the 8th of May 1848, on the rocky ledge immediately 

 above the Praya Formoza, near Funchal. It has been subsequently, however, 

 taken by Professor Heer, at the Gorgulho, in the vicinity of the same spot ; as also 

 by M. Rousset. It rims with extreme rapidity, and has more the appearance, at 

 first sight and when in motion, of a j)ale-coloiu'ed ant than of a Coleojiterous 

 insect.
