198 INSECTA MADERENSIA. 



front where it is considerably curved outwards. Antenna and legs a little paler than the rest of 

 the surface, being testaceous. 



Independently of the structural characters ali'eady enumerated, the present 

 insect may be at once known from the common Mycetceu liirta, to which in many 

 respects it is so nearly allied, by its broader and less acmninated outline (especially 

 posteriorly), by its shorter, ^ider and more shining prothorax (on which the raised 

 sublateral costa, which is so conspicuous in that genus, is but faintly expressed by 

 a small, obsciu-e, and exceedingly abbreviated ridge on either side beliind), and by 

 its vei-y much less sculptured smface, — its elytra (which are broad at their base, 

 and hare a distinct sutural stria on each) displaying moreover no tendency what- 

 soever to have thcii' pimctures even longitudinally disposed, and, therefore, 

 a fortiori, of being deeply and regularly punctate-s^/v'«ie(Z as in Ilycetcea. It is 

 apparently exceedingly rare, subsisting, for the most part, about, or in the imme- 

 diate Wciuity of dwellings. I tii-st captui'ed it, in November of 1847, in a house 

 in Funchal : and in the sunmicr of 1850 several specimens occurred to me beneath 

 the bark of an old Spanish chestnut-tree in the north of the island, — in Senhor 

 Louiz Acciaioly's vineyard at Santa Anna.

Ty2>h(ca (characterized wrongly by Stephens in 1830, and rightly by Curtis in 

 1838) is very nearly aUied, in its structural details, to Litargiis. It may however 

 be known by its pallid hue, by its oblong and exceedingly pubescent body, and by 

 its robust and corneous ligula. The basal joint of aU its tarsi is much less elon- 

 gated than in Litargus, whilst that of the front male pair is, lilvcwise, not so broad. 

 In its habits it is more fungivorous than subcortical; nevertheless it is often
