MADEIRAN COLEOPTERA, 63 
mediate altitudes. Having already described this species in the 
Insecta Maderensia, I have not thought it necessary to supply, here, 
more than the above corrected diagnosis,—which will serve to distin- 
guish it from its newly discovered allies more satisfactorily than the 
one there given.

Inhabits Madeira proper, principally within the sylvan districts. 
It will be perceived that I have adopted, in this Catalogue, the title of 
gyrinoides, Mshm, instead of dimidiatus, Sturm, for the present Hphi- 
stemus, under the latter of which names I had recorded it in the 
Insecta Maderensia. Ihave felt compelled to do this, in deference 
to the right of priority, because there is no doubt whatsoever that 
the Madeiran insect is identical with that which has been universally 
known in this country as the Dermestes gyrinoides of Marsham, for 
upwards of half a century, and which was also sufficiently well cha- 
racterized by Mr. Stephens, from the original Marshamian type (still 
extant in his collection), in 1829. It is extremely variable, as re- 
gards hue, its tendency being to become more or less rufescent to- 
wards its apex; and when thus brightly coloured (the aberrant 
state in Madeira, as well as in England,—and I believe, also, through- 
out Europe generally) it is the EF. dimidiatus of the continental 
cabinets. :
