50 INSECTA MADERENSIA. 



Caralus binotatus, Fab. Enf. Si/st. i. 151 (1792). 

 Harpalus hinotatus, Gryll. Ins. Suec. ii. 122 (1810). 

 Anisodactylus hinotatus, Dej. Spec, des Col. iv. 140 (1829). 

 , Heer, Fna Col Helv. 100 (1841). 



Habitat sub lapidibus per litora rivTiloram atque in locis humidis Maderse, infra 3000' s. ni., toto anno 

 vulgaris. 



A. elongate, deep black ; the males slightly shining, the females a little opake. Head with two 

 irregular longitudinal impressions between the eyes, and sometimes with a very obscure rufous 

 spot in the centre of its forehead. Prothurax subquadrate, a little narrowed posteriorly, the 

 hinder angles nearly right angles; with a longitudinal channel down the disk, and a large, 

 shallow, roughened fovea on either side at the base. Elytra elongate, rather convex, deeply 

 striated, the stripe being impunctate, and the interstices convex and likewise impunctate. Legs 

 deep pitchy-black. Antenna at base and extreme ape.x, palpi at apex, and the tarsi also at apex, 

 rufo-ferruginous. 



A most abundant insect throughout Eurojie and the north of Africa ; and 

 tolerably common in most parts of Madeii'a below the altitude of about 3000 feet 

 above the sea, where it occurs beneath stones at the edges of the streams. At the 

 Curral das Romeiras, and in the other raiines above Funchal, I have at times 

 observed it in considerable profusion. 



Genus 18. HARPALUS. 



LatreiUe, Gen. Crust, et Ins. i. 201 (180G). 



Corpus mediocre, oblongum : prothorace subquadrato, postice plus minusve attenuate : alis ssppius 

 amplis, sed in specie Maderensi una obsoletis. Antenna tiliiormes, capitis prothoracisque longi- 

 tudinc, articulo prime scqvientibus robustiore, secundo bren. Labrum subquadi-atum, antice 

 leviter emarginatum et setis paucis longissimis instructum, angulis anticis rotundatis ciliatis. 

 Mandilmlu' breves acuta;, dentc medio brevi interno obtuso instructae, basi subdenticulatae. 

 MaxilUe biloba; : lubo exienio palpiformi biarticulato : interno acuto incurvo, apice uncinate, intus 

 valde ciliato. Palpi filiformes, articulo ultimo fusiformi-subtruncato. Mentum transversum, 

 antice profunde emarginatum et dente medio brevi obtuso (rarissime obsoleto) instructum. Ligula 

 cornea angusta, apice truncata ; pai-aylossis amplis membranaceis rotundatis, earn j)aulo supcran- 

 tibus. Pedes validi : tarsis anterioribus in maribus articulis quatuor dilatatis, subtus biseriato- 

 setosis : unguiculis simpUcibus. 



The present genus, so AAddely distributed over the world, has apparently Imt foui* 

 representatives in the Madeu-a Islands, thi-ee of which arc common Em-opean 

 species, whilst the other, which belongs to an altogether dilferent type of form, is 

 peculiar to this region. There is but little fear of confoimding the Harpcdi Avith 

 any other insects witl\ wliich we are here concerned, theii' oblong bodies, and 

 usually l)lack or obscure surfaces, added to the four powerfully dilated anterior 

 tarsi of their male sex, beins; of themselves sufficient wherel)v to distim^uish them 

 from the allied groups.
