CANARIAN COLEOPTERA. 301 



Although attached to the Tamarisk, the present insect is appa- 

 rently quite distinct from the Mediterranean N. famarisci, palli- 

 dulus (which has unarmed femora), posticus, and stigmaticus, of which 

 the habits are similar. Indeed the first two of these are now before 

 me ; whilst the third is remarkable (inter alia) for its anterior femora 

 being- 6/spinulose, and for its elytra having merely a short, obscure, 

 darker line towards the apex of each. And judging from the de- 

 scription of the stigmaticus, I gather that that insect must have its 

 rostrum free from basal sulci, and its elytra more finely striated, and 

 with only a small speck on the third interval. I am, further, in- 

 formed by M. Jekel that he believes this species to be new, andj^er- 

 hai^s identical with an uncharacterized one from Egypt. 



Hitherto I have observed the N. lunulatus only in Grand Canary 

 — where, ou the 16th of April 1858, I brushed it, somewhat abun- 

 dantly, from off the shrubs of Tamarix gallica, L., growing at the 

 edges of the stream at Mogan, in the south-western district of that 

 island. 



(Subfam. TYCHIIDES.) 



Genus 194. SIBYNES. 

 Schonherr, Cure. Disp. Meth. 247 (1826). 

 Apart from minor distinctions, the genus Sihynes may be recog- 

 nized by its 6-jointed funiculus, and by the apices of its elytra being 

 separately rounded-off so as to expose a small portion of the pygi- 

 dium. The species are for the most part rather thick and oblong- 

 quadi-ate, though with their upper surface a little flattened ; their 

 prothorax is usually somewhat bisinuated along its hinder edge ; and 

 the scales with which they are densely clothed are more or less 

 shining and sericeous.

 This fine Sihynes is at once remarkable for the sericeous golden- 

 brown scales with which it is densely clothed, and which are be-
