 passim. 



The European M. quadricollis (which occurs also at Madeira) is 

 rather common in certain positions at the Canaries. I have taken 

 it abiuidantly, beneath vegetable rejectamenta, around Haria in the 

 north of Lanzarote, from under camels' dung in the Rio Palmas of 

 Fuerteventura, and near Orotava of Teneriffe ; in the first of which 

 islands it was found likewise by Mr. Gray and Dr. Crotch.

Habitat Lanzarotam et Teneriffam, rarissima. 



The present Monotoma (which, like the last one, is a weU-known 

 European species, and which is fomid also at Madeira) would appear 

 to be rare in these islands. Indeed hitherto I have myself taken but 

 a single Canarian example, — namely near Haria, in the north of 

 Lanzarote. Two more, however, have come beneath my observation, 

 captiired by Dr. Crotch in Teneriffe. 



Genus 86. TARPHIUS.

Habitat Teneriffam, in lauretis editioribus, trimcis ramulisque ar-

For the specific characters of the nine TarpMi here enumerated, 

 and their various diagnostic features, I must refer to my paper (above 

 aUuded to) which has lately been published in the ' Journal of Ento- 

 mology.' The T. simplex is not imcommon within the laurel-districts 

 of Teneriffe, — where (hke the other species) it may be found adhering 

 to the undersides of pieces of wood, the fallen trunks of trees, stones.
