22 INSECTA MADERENSIA. 



recurved, with the punctures towards the lateral angles almost obsolete, and the 

 striae of its elytra somewhat more evidently pimctate. It is exceedingly rare on 

 the Dezerta Grande, the only spot in which I have hitherto observed it bcuig, 

 under stones, at the upper edge of the precipitous gorge which descends to the 

 eastern shore from the immediate head of the long northern vaUey. On the Flat 

 Dezerta, or Ilheo Chao, I have not succeeded in detecting it ; nor as yet in any 

 part of Madeira proper. 



Genus 9. ZARGUS, TTW. (Tab. I. fig. 4, 5 et 6.) 



Corpus mediocre, clongato-ovatum, deprcssum, Calatlio habitii generali proximum sed ab eo certe 

 distinctum : pruthorace subcordato : ehjtris plus minusve inteiTupto-striatis : alls obsolctis. An- 

 tennee filiformes gi-acillimse, capite prothoraceque paulo longiores, articulo primo elongate sat 

 robusto clavato, secimdo brevij tertio primo breviore. Labrum (I. 4 a) prominulum transversum, 

 antice profunde bilobum, lobo quoque seta longissima apicali instnicto. Mandibula porrectse 

 elongatse angustatas^ ad apicem subito intlex;e acutse, infra apicem dente magno acuto basi 

 latissimo munitaj, margine interno valde ciliato. Maxilla (1.46) bilobse, angusto-elongatse : 

 lobo externa pali)ifornii biarticulato, articulo primo elongato flexuoso, secundo crassiorc clongato- 

 subovato : interno huic paulo longiore, angusto recto, ad apicem subito ineurvo acutissimo, intus 

 dense ct fortiter ciliato. Palpi elongati subfiliformcs : maxiUares articulo primo minuto, secundo 

 elongato subcurvato, tertio quartoque longitudine fequabbus, hoc elongato fusiformi-ovato : la- 

 hiales (I. 4 c) c scapis ligulaj connatis surgentcs, articulo primo minuto, secundo tertioque sub- 

 ajqualibus, illo setis duabus internis aucto, boc elongato fusiformi-subovato. Mentum transver- 

 sum, antice profunde emarginatum et dente medio nullo instructum. Ligula elongata apice 

 truncata, membranacea, in media parte antica subcornea setisque duabus omata; paraglossis 

 tcnuissimis acuminatis, cam supcrantibus. Pedes longiusculi, gracilcs : tarsis anticis in maribus 

 (I. 4(f, 4e) articulis primo, secundo et tertio valde dilatatis subtus lacinioso-papillosis (primo 

 obtriangulari angulis anticis rotundatis, secundo tertioque subrotundatis), quarto parvo triangu- 

 lari ; ultimo in omnibus elongato subclavato : unguiculis simplicibus. 



Huic generi nomen dedi in honorem Zargo, insignis viri Lusitanici, qui, a.d. 1419, !Maderam primus 

 invenisse apud historic scriptores memoratur. 



There is perhaps no genus which it has been found necessary to establish, in the 

 present work, for the reception of new Coleopterous forms from the ]\[adeira 

 Islands, more interesting, or which may be said to be better defined or more 

 strictly uidigcnous, than the present one ; for not only docs it differ in many of its 

 most essential characters from the subfamily Uarpalides (to wliich, nevertheless, 

 it evidently belongs), but, — if we except a portion of the Scaritides, — it recedes, in 

 its powerfully dentate and ciliated mandibles, fi'om every member of the entire 

 Carabidce \nih. which I am acquainted. "VMiilst however there can be no doubt 

 but that it is correctly referred to Wxa Uarpalides, its exact position therein is not at 

 first sight altogether intelligible. From the Fterosticliidea (the second of the three 

 great divisions of the HarpaUdes), to some of the genera of Avliich, particidarly 

 Calatlnis, it most nearly, in its outward aspect, approximates, the rounded form of 

 its dilated tarsal joints, which are densely clothed beneath with ragged appendages,
