170 INSECTA MADERENSIA. 



maxillares articulo primo angusto flexuoso, secundo et tertio crassioribus subxqualibus, ultimo 

 ovato : lahialcs e scapis ligulae connatis surgentcs, articulo primo flexuoso, secundo crassiore 

 brevi, ultimo apice subtruncato. Mentum amplum, antice angustatum, summo apice excavato- 

 emarginato. Li(jula subquadrata, apice membranri pilosa ancta. Pedes minus robusti : tarsis 

 simplicibus (in maribus bcteromeris) ; articuiis omnibus, ultimo excepto, subjequalibus latitudiue 

 vix decrescentibus. 



The Cnjptoj)hagi may be at once clistinguislicd by the stmctm-c of theii- pro- 

 thorax, Avkich, throughout the genus, presents but slight successive modifications 

 of a type which is common to the whole of it, — in which the anterior angles are 

 developed into a more or less elongated shoulder, or ridge (which forms a kind of 

 lengthened tooth, with the apex usually pointing backwards), whUst the remaining 

 l)ortion of the edges are, either partially or altogether, subcrenulated, and have a 

 small and more or less evident spine, on either side, about the centre. The 

 species are generally somewhat pubescent and convex, and are principally of a 

 testaceous, or pale ferruginous hue ; whilst the males, u nl ike those of the Silvani, 

 are heteromerous, — the tarsal joints moreover, of both sexes, being (-nith the 

 exception of the apical one) of almost equal length. They are insects of rather 

 various habits, residing either in the open coimtry (amongst Bolcti, and beneath 

 the loose bark and moss of trees), or else attaching themselves, like the Silcani 

 and many of the Seteromera, to inhabited spots, — subsisting on grain, farinaceous 

 substances, biscuits, and other articles of commerce, to which they fi-equently do 

 considerable damage on board ship. The same species in fact wUl often adapt 

 themselves to these opposite modes of life, — as is eminently the case with the 

 single Madeiran representative of the group.

C. obloug-ovatc, convex, pale ferruginous, or sometimes almost testaceous, slightly shining, and 

 densely clothed with a long and silken pubescence. Head &\x<X prothvrdx deeply punctured : the 

 latter more or less transverse-quadrate (varying a little in length in different specimens), with 

 the anterior angles enlarged into an obtuse, shoulder-like projection, or ridge, and with a minute, 

 subrecurved tooth about the centre of cither lateral edge,— the space between which and the
