(Subfam. 5. ERIRHINIDES.) 
Genus 128. TYCHIUS. 
(Germar) Schoén., Cwre. Disp. Meth. 245 (1826). 
314. Tychius robustus. 
Tychius robustus, Woll., Ins, Mad. 344 (1854). 
Inhabits the entire Madeiran Group, being more especially abun- 
dant in Porto Santo,—where, at certain seasons, it teems beneath 
stones in low spots towards the southern coast. On the three 
Dezertas it is scarcer, nevertheless at times sufficiently common. But 
in Madeira proper it is exceedingly rare, and I have not myself 
hitherto observed it in that island ; it would appear indeed to be con- 
fined to the Sao Lourenco promontory (the nearest point to both Porto 
Santo and the Dezertas), in which locality it has been recently 
discovered by Mr. Bewicke. 
315. Tychius albosquamosus. 
Tychius albosquamosus, Woll., Ins. Mad. 345 (1854). 
Inhabits the Dezerta Grande, and is hitherto unique,—the single 
specimen (now in the British Museum) haying been captured by 
myself on that island during May 1850. 
316. Tychius filirostris. 
Tychius filirostris, Woll., Ins. Mad. 546 (1854). 
Inhabits Porto Santo; exceedingly rare. Two specimens only have 
as yet come beneath my notice. They were both captured, by my- 
self, in the low calcareous district of the Zimbral d’Areia, in the east 
of the island,—one during April 1849, and the other in May 1855,
