tibiae being simple (or unarmed with additional spines) towards 

 their outer apex; and in its tarsal claws being set more closely 

 together. 



8. Ccenopsis Waltonij Schonh. 



C. ovatus, niger, fusco-cinereo squamosus et setis rigidis longiusculis 

 dense obsitus ; capite postice longitudinal iter strigoso, rostro brevi, 

 oculis prominulis ; prothorace densissime ruguloso-punctato; elytris 

 profunda striato-punctatis, punctis magnis ; antennis pedibusque 

 ferrugineis squamosis, illis versus basin scrobis (mox ante oculos) 

 insertis, his breviusculis, tibiis ad apicem simphcibus (baud spinu- 

 loso-terminatis).

Trachyphloeus Waltoni, Schonh., Gen. et Spec. Cure. vii. 115 (1843). 



C. ovate, black, densely clothed with brownish-cinereous scales 

 and studded with long and erect setse. Head closely longitudi- 

 nally strigulose behind, with the eyes rounded and rather pro- 

 minent, and with the rostrum short ; the last with the lateral 

 scrobs likewise short and curved upwards to the upper margin 

 of the eye, and with the antennae implanted into it near its base. 

 Prothorax very densely punctured, the punctures being rather 

 small and more or less confluent. Elytra deeply striate-punc- 

 tate, the punctures being extremely large. Antennce and legs 

 ferruginous, but squamose : the former relatively longer and 

 slenderer than those of the Trachyphloms scaber, and with their 

 scape more flexuose at the base ; the latter rather short, with the 

 tibise simple at their extreme apices — not being fringed with, or 

 terminated by, minute spinules. 



A single specimen has lately been communicated by Mr. Be- 

 wicke (by whom it was captured at the Mount, above Funchal), 

 which appears to me to agree precisely with my British examples 

 of the C. Waltoni — possessing the longitudinal frontal strig^, 

 the abbreviated rostrum, the enormous elytral punctures, and 

 tlie numerous other features which distinguish that insect ; and 

 I think it far from unlikely, therefore, that it may have been 

 imported accidentally into Madeira through the medium of the 

 English residents, who have long been in the habit of bringing 

 boxes of plants, at intervals, from our own country, in order to 

 replenish their gardens with the familiar forms of more northern 

 latitudes. And, indeed, so long as such is the case, it seems 

 impossible to foretell the amount of additions which may and 

 must accumulate to the fauna in the course of every few years, 

 though happily it is not difficult, when studied in situ, to draw 

 the line of demarcation, in at all events a general way, between 

 that portion of the Coleopterous population which is truly indi-
