INSECTA MADERENSIA. 23 



arranged promiscuously and not distributed in a double row ; added to the un- 

 toothed emargination of its mentum, its simple claws, its deeply bilobed upper lip, 

 membranaceous Ugula, and its largely developed paraglossre, entirely remove it. 

 And although the first four of the above details (namely, the structure of its male 

 foot, above and below, its unserrated claws, and its mentimi destitute of a central 

 tooth) point to the Chlceniidea as its more natm^al. location ; yet the remaioing 

 three (namely, the remarkable form of its upper Hp, its thin imperfect ligula, and 

 its ample paraglossae), in addition to its porrected, strongly dentate, and ciliated 

 mandibles, are altogether as unrepresented in that division as they are iu the 

 Pterostlchldea, and would seem almost to debar it from entrance even there. Still 

 there is no other section of the Harpalides which, as usually defined, could so Avell 

 receive it ; and since it is necessarily a choice between difiiculties in assigning it a 

 position at all, we must be content to accept that one which offers the fewest 

 obstacles to its admission. Whilst therefore it must needs present anomalies 

 wherever it be placed, yet I believe that it wiU be found, upon the whole, lohen at 

 the end of the Chlceniidea (and immediately before the commencement of the 

 Pterostichidea) to be nearest to those genera with which it has the greatest 

 affinity*. And strange as it may appear in a geographical poiat of view, I am 

 inclined to suspect that it has perhaj)s a closer connection with the little genus 

 Homethes, Newman, from Australia, than with any other form liitherto discovered. 

 The Zargi are extremely voracious, and have as much the habits as they have the 

 external aspect of the Calathi. They reside, almost exclusively, beneath stones 

 in grassy spots, and are more particularly abundant at low and intermediate 

 altitudes.

Z. nigro-piceus, supra piceus opacus valde depressus, protliorace subelongato angusto cordato niar-

 pallidis.

* Ti'ue it is indeed that its extremely membranaceous ligula, with the minute subcomeous centre, 

 finds an analogue in the genus Bracldnus ; and that the papillose under surface of its male tarsi, its un- 

 toothed meuttmi, simple claws, and subclavate palpi are, likewise, severally represented in the other 

 genera of the Braclunides ; nevertheless I cannot persuade myself that it has any real aflSnity whatsoever
