MADEIRAN COLEOPTERA. 69 
Limbs a little shorter and less robust than those of the M. spini- 
fera. 
A species which would appear to be the Madciran representative 
of the common European M. picipes. Its prothorax however is more 
quadrate, or straighter at the sides, than in that insect (being a little 
wider in front, and rather less rounded behind), and the spine at the 
anterior angle is both less developed and less outwardly-directed. Its 
elytra, also, are perhaps just perceptibly less ovate, and its antennze 
a trifle shorter (?) and more robust. Both of the Monotome here 
described, moreover, have their shoulders somewhat more porrected, 
or (which amounts to the same thing) the base of their elytra more 
scooped-out, than in the M. picipes ; and it is just possible (as in- 
deed Mr. Janson has suggested to me) that they may be but the 
sexes of a single species. Nevertheless, since they differ so mate- 
rially inter se, it is of course impossible, in the absence of any evi- 
dence to that effect, to regard them as such. Four examples only of 
the MW. congener (all captured in Madeira proper) have hitherto come 
beneath my notice: two of them were taken by myself, during the 
summer of 1855,—one in the north of the island, in the Ribeiro de 
Sao Jorge; and the other (which is now in the British Museum) on 
the Eschada of Camacha, in the south ;—the third was found by 
Mr. Bewicke, at the Mount, above Funchal; and the fourth by 
Mr. Mason, in the Boa Ventura.

Genus 72. MYCETAA. 
(Kby) Steph., IU. Brit. Ent. iii, 80 (1830). 
Mycetea, the sole exponent of which hitherto detected is so uni- 
versal throughout Europe, is very closely allied to Microchondrus ; 
but the distinctive features of the two may be partially gathered by 
a reference to that genus, in the Insecta Maderensia. We may how- 
ever briefly state, that the fully developed inner maxillary lobe of
